Jak pogrupować RadioButton z różnych LinearLayouts?

Zastanawiałem się, czy można zgrupować każdy singiel RadioButtonw unikalny sposób, RadioGroup zachowując tę ​​samą strukturę. Moja konstrukcja wygląda tak:

• LinearLayout_main
  • LinearLayout_1
    • RadioButton1
  • LinearLayout_2
    • RadioButton2
  • LinearLayout_3
    • RadioButton3

Jak widać, teraz każdy RadioButtonjest dzieckiem innym LinearLayout. Próbowałem użyć poniższej struktury, ale nie działa:

• Radiogroup
  • LinearLayout_main
    • LinearLayout_1
      • RadioButton1
    • LinearLayout_2
      • RadioButton2
    • LinearLayout_3
      • RadioButton3

Wygląda na to, że dobrzy ludzie w Google / Androidzie zakładają, że kiedy używasz RadioButtons, nie potrzebujesz elastyczności, która jest oferowana w każdym innym aspekcie systemu interfejsu / układu Androida. Mówiąc prościej: nie chcą, abyś zagnieżdżał układy i przyciski opcji. Westchnienie.

Więc musisz obejść ten problem. Oznacza to, że musisz samodzielnie zaimplementować przyciski opcji.

To naprawdę nie jest zbyt trudne. W swojej onCreate () ustaw swoje RadioButtons z ich własnym onClick (), aby po ich aktywacji ustawiały oneChecked (true) i robiły odwrotnie dla pozostałych przycisków. Na przykład:

class FooActivity {

    RadioButton m_one, m_two, m_three;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...
        m_one = (RadioButton) findViewById(R.id.first_radio_button);
        m_two = (RadioButton) findViewById(R.id.second_radio_button);
        m_three = (RadioButton) findViewById(R.id.third_radio_button);

        m_one.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                m_one.setChecked(true);
                m_two.setChecked(false);
                m_three.setChecked(false);
            }
        });

        m_two.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                m_one.setChecked(false);
                m_two.setChecked(true);
                m_three.setChecked(false);
            }
        });

        m_three.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                m_one.setChecked(false);
                m_two.setChecked(false);
                m_three.setChecked(true);
            }
        });

        ...     
    } // onCreate() 

}

Tak, wiem - stara szkoła. Ale to działa. Powodzenia!

Użyj tej klasy, którą stworzyłem. Znajdzie wszystkie możliwe do sprawdzenia dzieci w Twojej hierarchii.

import java.util.ArrayList;

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Checkable;
import android.widget.LinearLayout;

public class MyRadioGroup extends LinearLayout {

private ArrayList<View> mCheckables = new ArrayList<View>();

public MyRadioGroup(Context context) {
    super(context);
}

public MyRadioGroup(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

public MyRadioGroup(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

@Override
public void addView(View child, int index,
        android.view.ViewGroup.LayoutParams params) {
    super.addView(child, index, params);
    parseChild(child);
}

public void parseChild(final View child)
{
    if(child instanceof Checkable)
    {
        mCheckables.add(child);
        child.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                for(int i = 0; i < mCheckables.size();i++)
                {
                    Checkable view = (Checkable) mCheckables.get(i);
                    if(view == v)
                    {
                        ((Checkable)view).setChecked(true);
                    }
                    else
                    {
                        ((Checkable)view).setChecked(false);
                    }
                }
            }
        });
    }
    else if(child instanceof ViewGroup)
    {
        parseChildren((ViewGroup)child);
    }
}

public void parseChildren(final ViewGroup child)
{
    for (int i = 0; i < child.getChildCount();i++)
    {
        parseChild(child.getChildAt(i));
    }
}
}

Cóż, napisałem tę prostą lekcję.

Po prostu użyj tego w ten sposób:

// add any number of RadioButton resource IDs here
GRadioGroup gr = new GRadioGroup(this, 
    R.id.radioButton1, R.id.radioButton2, R.id.radioButton3);

lub

GRadioGroup gr = new GRadioGroup(rb1, rb2, rb3);
// where RadioButton rb1 = (RadioButton) findViewById(R.id.radioButton1);
// etc.

Możesz na przykład wywołać to w onCreate () z Activity. Bez względu na to, które RadioButtonklikniesz, pozostałe zostaną odznaczone. Nie ma też znaczenia, czy niektórzy RadioButtonssą w środku RadioGroup, czy nie.

Oto klasa:

            for (RadioButton rb : radios) {

                ViewParent p = rb.getParent();
                if (p.getClass().equals(RadioGroup.class)) {
                    // if RadioButton belongs to RadioGroup, 
                    // then deselect all radios in it 
                    RadioGroup rg = (RadioGroup) p;
                    rg.clearCheck();
                } else {
                    // if RadioButton DOES NOT belong to RadioGroup, 
                    // just deselect it
                    rb.setChecked(false);
                }
            }

            // now let's select currently clicked RadioButton
            if (v.getClass().equals(RadioButton.class)) {

                rb.setChecked(true);
            }

        }
    };

}

Możesz go używać w swoim układzie w taki sam sposób, jak zwykłego, RadioGroupz wyjątkiem tego, że działa również z RadioButtonwidokami zagnieżdżonymi :

</RecursiveRadioGroup>

To rozwiązanie nie zostało opublikowane, więc publikowanie:

Krok 0: Utwórz CompoundButton previousCheckedCompoundButton;zmienną globalną jako.

Krok 1: Utwórz OnCheckedChangedListenerdla przycisków opcji

CompoundButton.OnCheckedChangeListener onRadioButtonCheckedListener = new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (!isChecked) return;
            if (previousCheckedCompoundButton != null) {
                previousCheckedCompoundButton.setChecked(false);
                previousCheckedCompoundButton = buttonView;
            } else {
                previousCheckedCompoundButton = buttonView;
            }
        }
    };

Krok 3: dodaj słuchacza do wszystkich przycisków radiowych:

radioButton1.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton2.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton3.setOnCheckedChangeListener(onRadioButtonCheckedListener);
radioButton4.setOnCheckedChangeListener(onRadioButtonCheckedListener);

Otóż ​​to!! Jesteś skończony.

Ech ... Naprawdę winę za to, że Androidowi brakuje tak podstawowej funkcjonalności.

Na podstawie odpowiedzi @ScottBiggs, oto możliwie najkrótszy sposób na zrobienie tego z Kotlin:

var currentSelected = button1
listOf<RadioButton>(
    button1, button2, button3, ...
).forEach {
    it.setOnClickListener { _ ->
        currentSelected.isChecked = false
        currentSelected = it
        currentSelected.isChecked = true
    }
}

Stworzyłem te dwie metody, aby rozwiązać ten problem. Wszystko, co musisz zrobić, to przekazać ViewGroup, w którym znajdują się RadioButtons (może to być RadioGroup, LinearLayout, RelativeLayout itp.) I ustawia wyłącznie zdarzenia OnClick, to znaczy zawsze, gdy jeden z RadioButtons jest elementem podrzędnym ViewGroup ( na dowolnym zagnieżdżonym poziomie), pozostałe są odznaczone. Działa z dowolną liczbą zagnieżdżonych układów.

public class Utils {
    public static void setRadioExclusiveClick(ViewGroup parent) {
        final List<RadioButton> radios = getRadioButtons(parent);

        for (RadioButton radio: radios) {
            radio.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    RadioButton r = (RadioButton) v;
                    r.setChecked(true);
                    for (RadioButton r2:radios) {
                        if (r2.getId() != r.getId()) {
                            r2.setChecked(false);
                        }
                    }

                }
            });
        }
    }

    private static List<RadioButton> getRadioButtons(ViewGroup parent) {
        List<RadioButton> radios = new ArrayList<RadioButton>();
        for (int i=0;i < parent.getChildCount(); i++) {
            View v = parent.getChildAt(i);
            if (v instanceof RadioButton) {
                radios.add((RadioButton) v);
            } else if (v instanceof ViewGroup) {
                List<RadioButton> nestedRadios = getRadioButtons((ViewGroup) v);
                radios.addAll(nestedRadios);
            }
        }
        return radios;
    }
}

Sposób użycia w ramach działania wyglądałby tak:

ViewGroup parent = findViewById(R.id.radios_parent);
Utils.setRadioExclusiveClick(parent);

Napisałem własną klasę grup radiowych, która pozwala zawierać zagnieżdżone przyciski opcji. Sprawdź to. Jeśli znajdziesz błędy, daj mi znać.

 * This class is used to create a multiple-exclusion scope for a set of compound

 * previously checked compound button within the same group. Intially, all of
 * the compound buttons are unchecked. While it is not possible to uncheck a
 * particular compound button, the group can be cleared to remove the checked
 * state. Basically, this class extends functionality of

 * 
 * <b>IMPORTATNT! Follow these instruction when using this class:</b><br>
 * 1. Each direct child of this group must contain one compound button or be

 * 2. Do not set any "on click" or "on checked changed" listeners for the childs

Musisz zrobić dwie rzeczy:

1. Posługiwać się mListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
2. Stwórz własną implementację widoku wiersza Checkable.

Myślę więc, że lepszym rozwiązaniem jest zaimplementowanie Checkable wewnątrz twojego wewnętrznego LinearLayout: (dzięki daichan4649, z jego linku https://gist.github.com/daichan4649/5245378 , wziąłem cały kod wklejony poniżej)

CheckableLayout.java

    }

        super(context, attrs, defStyle);
    }

        return checked;
    }

    @Override

        if (this.checked != checked) {
            this.checked = checked;
            refreshDrawableState();

            for (int i = 0; i < getChildCount(); i++) {
                View child = getChildAt(i);
                if (child instanceof Checkable) {

                }
            }

        }

Stoję przed tym samym problemem, ponieważ chcę umieścić 4 różne przyciski radiowe w dwóch różnych układach liniowych, a ten układ będzie elementem podrzędnym grupy radiowej. Aby osiągnąć pożądane zachowanie w RadioGroup, przeładowałem funkcję addView

Oto rozwiązanie

public class AgentRadioGroup extends RadioGroup
{

    public AgentRadioGroup(Context context) {
        super(context);
    }

    public AgentRadioGroup(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onViewAdded(View child) {
        if( child instanceof ViewGroup)
        {
            ViewGroup viewGroup = (ViewGroup) child;
            for(int i=0; i<viewGroup.getChildCount(); i++)
            {
                View subChild = viewGroup.getChildAt(i);
                if( subChild instanceof ViewGroup )
                {
                    onViewAdded(subChild);
                }
                else
                {
                    if (subChild instanceof RadioButton) {
                        super.onViewAdded(subChild);
                    }
                }
            }
        }
        if (child instanceof RadioButton)
        {
            super.onViewAdded(child);
        }
    }
}

Nic nie stoi na przeszkodzie, aby wdrożyć tę strukturę układu ( RadioGroupw rzeczywistości jest to podklasa LinearLayout), ale nie powinieneś. Po pierwsze, tworzysz strukturę o głębokości 4 poziomów (używając innej struktury układu możesz to zoptymalizować), a po drugie, jeśli RadioButtonsnie jesteś bezpośrednim dzieckiem a RadioGroup, jedyny element wybrany w grupie nie będzie działał. Oznacza to, że jeśli wybierzesz jeden Radiobuttonz tego układu, a następnie wybierzesz inny RadioButton, skończysz z dwoma RadioButtonswybranymi zamiast ostatnio wybranego.

Jeśli wyjaśnisz, co chcesz zrobić w tym układzie, może polecę ci alternatywę.

Moje 0,02 $ na podstawie @infografnet i @lostdev (również dziękuję @Neromancer za sugestię przycisku złożonego!)

public class AdvRadioGroup {
    public interface OnButtonCheckedListener {
        void onButtonChecked(CompoundButton button);
    }

    private final List<CompoundButton> buttons;
    private final View.OnClickListener onClick = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            setChecked((CompoundButton) v);
        }
    };

    private OnButtonCheckedListener listener;
    private CompoundButton lastChecked;


    public AdvRadioGroup(View view) {
        buttons = new ArrayList<>();
        parseView(view);
    }

    private void parseView(final View view) {
        if(view instanceof CompoundButton) {
            buttons.add((CompoundButton) view);
            view.setOnClickListener(onClick);
        } else if(view instanceof ViewGroup) {
            final ViewGroup group = (ViewGroup) view;
            for (int i = 0; i < group.getChildCount();i++) {
                parseView(group.getChildAt(i));
            }
        }
    }

    public List<CompoundButton> getButtons() { return buttons; }

    public CompoundButton getLastChecked() { return lastChecked; }

    public void setChecked(int index) { setChecked(buttons.get(index)); }

    public void setChecked(CompoundButton button) {
        if(button == lastChecked) return;

        for (CompoundButton btn : buttons) {
            btn.setChecked(false);
        }

        button.setChecked(true);

        lastChecked = button;

        if(listener != null) {
            listener.onButtonChecked(button);
        }
    }

    public void setOnButtonCheckedListener(OnButtonCheckedListener listener) { this.listener = listener; }
}

Użycie (z dołączonym odbiornikiem):

AdvRadioGroup group = new AdvRadioGroup(findViewById(R.id.YOUR_VIEW));
group.setOnButtonCheckedListener(new AdvRadioGroup.OnButtonCheckedListener() {
    @Override
    public void onButtonChecked(CompoundButton button) {
        // do fun stuff here!
    }
});

Bonus: Możesz uzyskać ostatnio zaznaczony przycisk, listę całych przycisków, a także możesz sprawdzić dowolny przycisk po indeksie!

    int currentCheckedRadioButton = 0;
    int[] myRadioButtons= new int[6];
    myRadioButtons[0] = R.id.first;
    myRadioButtons[1] = R.id.second;
    //..
    for (int radioButtonID : myRadioButtons) {
        findViewById(radioButtonID).setOnClickListener(
                    new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (currentCheckedRadioButton != 0)
                    ((RadioButton) findViewById(currentCheckedRadioButton)).setChecked(false);
                currentCheckedRadioButton = v.getId();

            }
        });
    }

Chociaż jest to może starszy temat, chciałbym szybko podzielić się prostym, hakerskim kodem, który napisałem. Nie jest dla wszystkich i przydałoby się też pewne udoskonalenie.

Sytuacja, aby użyć tego kodu?
Ten kod jest dla osób, które mają układ oryginalnego pytania lub podobny, w moim przypadku był jak poniżej. To osobiście dotyczyło Dialogu, którego używałem.

• LinLayout_Main
  • LinLayout_Row1
    • ImageView
    • Przycisk radiowy
  • LinLayout_Row2
    • ImageView
    • Przycisk radiowy
  • LinLayout_Row3
    • ImageView
    • Przycisk radiowy

Co kod robi sam?
Ten kod wyliczy kiedykolwiek element podrzędny „LinLayout_Main”, a dla każdego elementu podrzędnego, który jest elementem „LinearLayout”, wyliczy ten widok dla wszystkich elementów RadioButtons.

Po prostu będzie wyglądać na rodzica „LinLayout_Main” i znajdzie wszystkie RadioButtons, które są w dowolnym podrzędnym układzie liniowym.

MyMethod_ShowDialog
okno dialogowe z plikiem układu XML, jednocześnie sprawdzając, czy ustawia "setOnClickListener" dla każdego znalezionego RadioButton

MyMethod_ClickRadio zapętli
każdy element RadioButton w taki sam sposób, jak „MyMethod_ShowDialog”, ale zamiast ustawiać „setOnClickListener”, zamiast tego „setChecked (false)” wyczyści każdy element RadioButton, a w ostatnim kroku „setChecked (false)” do elementu RadioButton, który nazywana zdarzeniem kliknięcia.

public void MyMethod_ShowDialog(final double tmpLat, final double tmpLng) {
        final Dialog dialog = new Dialog(actMain);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.layout_dialogXML);

        final LinearLayout tmpLayMain = (LinearLayout)dialog.findViewById(R.id.LinLayout_Main);
        if (tmpLayMain!=null) {
            // Perform look for each child of main LinearLayout
            int iChildCount1 = tmpLayMain.getChildCount();
            for (int iLoop1=0; iLoop1 < iChildCount1; iLoop1++){
                View tmpChild1 = tmpLayMain.getChildAt(iLoop1);
                if (tmpChild1 instanceof LinearLayout) {
                    // Perform look for each LinearLayout child of main LinearLayout
                    int iChildCount2 = ((LinearLayout) tmpChild1).getChildCount();
                    for (int iLoop2=0; iLoop2 < iChildCount2; iLoop2++){
                        View tmpChild2 = ((LinearLayout) tmpChild1).getChildAt(iLoop2);
                        if (tmpChild2 instanceof RadioButton) {

                                public void onClick(View v) {

        final LinearLayout tmpLayMain = (LinearLayout)dDialog.findViewById(R.id.LinLayout_Main);
        if (tmpLayMain!=null) {
            int iChildCount1 = tmpLayMain.getChildCount();
            for (int iLoop1=0; iLoop1 < iChildCount1; iLoop1++){
                View tmpChild1 = tmpLayMain.getChildAt(iLoop1);
                if (tmpChild1 instanceof LinearLayout) {
                    int iChildCount2 = ((LinearLayout) tmpChild1).getChildCount();
                    for (int iLoop2=0; iLoop2 < iChildCount2; iLoop2++){

Mogą być błędy skopiowane z projektu i przemianowane na Voids / XML / ID

Możesz także uruchomić ten sam typ pętli, aby dowiedzieć się, które elementy są zaznaczone

To jest zmodyfikowana wersja rozwiązania @ Infografnet. Jest prosty i łatwy w użyciu.

RadioGroupHelper group = new RadioGroupHelper(this,R.id.radioButton1,R.id.radioButton2); group.radioButtons.get(0).performClick(); //programmatically

Po prostu skopiuj i wklej

package com.qamar4p.farmer.ui.custom;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.view.View;
import android.widget.CompoundButton;
import android.widget.RadioButton;

public class RadioGroupHelper {

    public List<CompoundButton> radioButtons = new ArrayList<>();

    public RadioGroupHelper(RadioButton... radios) {
        super();
        for (RadioButton rb : radios) {
            add(rb);
        }
    }

    public RadioGroupHelper(Activity activity, int... radiosIDs) {
        this(activity.findViewById(android.R.id.content),radiosIDs);
    }

    public RadioGroupHelper(View rootView, int... radiosIDs) {
        super();
        for (int radioButtonID : radiosIDs) {
            add((RadioButton)rootView.findViewById(radioButtonID));
        }
    }

    private void add(CompoundButton button){
        this.radioButtons.add(button);
        button.setOnClickListener(onClickListener);
    }

    View.OnClickListener onClickListener = v -> {
        for (CompoundButton rb : radioButtons) {
            if(rb != v) rb.setChecked(false);
        }
    };
}

Jak pokazano w odpowiedziach, rozwiązaniem jest prosty niestandardowy hack. Oto moja minimalistyczna wersja w Kotlinie.

import android.widget.RadioButton

class SimpleRadioGroup(private val radioButtons: List<RadioButton>) {

    init {
        radioButtons.forEach {
            it.setOnClickListener { clickedButton ->
                radioButtons.forEach { it.isChecked = false }
                (clickedButton as RadioButton).isChecked = true
            }
        }
    }

    val checkedButton: RadioButton?
        get() = radioButtons.firstOrNull { it.isChecked }
}

wtedy po prostu musisz zrobić coś takiego w onCreate swojego działania lub onViewCreated fragmentu:

SimpleRadioGroup(listOf(radio_button_1, radio_button_2, radio_button_3))

To jest moje rozwiązanie w Kotlin dla niestandardowego układu z RadioButton w środku.

tipInfoContainerFirst.radioButton.isChecked = true

var prevSelected = tipInfoContainerFirst.radioButton
prevSelected.isSelected = true

listOf<RadioButton>(
    tipInfoContainerFirst.radioButton,
    tipInfoContainerSecond.radioButton,
    tipInfoContainerThird.radioButton,
    tipInfoContainerForth.radioButton,
    tipInfoContainerCustom.radioButton
).forEach {
    it.setOnClickListener { _it ->
    if(!it.isSelected) {
        prevSelected.isChecked = false
        prevSelected.isSelected = false
        it.radioButton.isSelected = true
        prevSelected = it.radioButton
    }
  }
}

Mam ten sam problem, muszę użyć przycisku radiowego dla płci i wszystkie były ze zdjęciem i tekstem, więc próbowałem go rozwiązać w następujący sposób.

W pliku java: Ustawiłem setOnCheckedChangeListener na wszystkich 3 przyciskach opcji i metodę nadpisywania, jak wspomniano poniżej, i działa dobrze dla mnie.

@Override
    public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
   switch (compoundButton.getId()){
       case R.id.rbMale:
           if(rbMale.isChecked()){
               rbMale.setChecked(true);
               rbFemale.setChecked(false);
               rbOther.setChecked(false);
           }
           break;
       case R.id.rbFemale:
           if(rbFemale.isChecked()){
               rbMale.setChecked(false);
               rbFemale.setChecked(true);
               rbOther.setChecked(false);
           }
           break;
       case R.id.rbOthers:
           if(rbOther.isChecked()){
               rbMale.setChecked(false);
               rbFemale.setChecked(false);
               rbOther.setChecked(true);
           }
           break;

   }
    }

Możesz użyć tego prostego kodu rozszerzenia RadioGroup. Upuść w nim dowolne układy / widoki / obrazy wraz z RadioButtons i zadziała.

Zawiera wywołanie zwrotne wyboru, które zwraca wybrany RadioButton z jego indeksem i można ustawić wybór programowo według indeksu lub identyfikatora:
