Odpowiedzi:
Posługiwać się:
String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));lub
String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));content://lub jakikolwiek inny Uri nie będący plikiem.
Metoda PathUtil będzie działać tylko w poniższym oreo, a jeśli to oreo, to prawdopodobnie ulegnie awarii, ponieważ w oreo nie otrzymamy identyfikatora, ale całą ścieżkę w data.getData (), więc wszystko, co musisz zrobić, to utworzyć plik z uri i pobierz jego ścieżkę z getPath () i podziel ją. poniżej znajduje się działający kod: -
Uri uri = data.getData();
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).Powyższy kod będzie działał w oreo i jeśli jest poniżej oreo to PathUtil będzie działał. Dzięki!
String filePath=PathUtil.getPath(context,yourURI);PathUtil.java
