Answer 1

像这样的东西应该工作

ContentResolver contentResolver = getContentResolver(); 
String columns = { 
    MediaColumns.TITLE, 
    AudioColumns.DURATION, 
    MediaColumns.DATA 
    // add more columns if you want to fetch more data 
}; 

Cursor cursor = contentResolver.query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,columns, null, null, null); 

while(cursor.moveToNext()) { 
    String title = cursor.getString(cursor.getColumnIndex(MediaColumns.TITLE)); 
    Long duration = cursor.getLong(cursor.getColumnIndex(AudioColumns.DURATION)); 
    String data = cursor.getString(cursor.getColumnIndex(MediaColumns.DATA)); 
    // handle song here 
}
