java - MediaStore 外部内容 URI 正在从 SDCARD 中获取数据

Question

我正在使用 MediaStore 和 Cursor 从指定文件夹中获取音频文件。我想要的是，它应该从手机的内部存储器中获取歌曲列表，但它是从 SDCARD 中获取的。虽然我尝试过使用 INTERNAL_CONTENT_URI 但它根本没有得到任何东西。请看一下，它有什么问题。任何帮助将不胜感激。

    String AudioFilePath = "%" +"/nexcox/voicerecorder/audio/" +"%";

    Uri uri= MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection= MediaStore.Audio.Media.DATA +" LIKE ? ";
    Cursor cursor=context.getContentResolver().query(uri,null,selection,
            new String[]{AudioFilePath},
            null);


    if (cursor!=null){
        if (cursor.moveToFirst()){
            do {
                String name = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
                String duration = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DURATION));
                String sourceLocation = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));

                AudioInfo audioInfo=new AudioInfo(name,duration,sourceLocation);
                audioInfos.add(audioInfo);
            }while (cursor.moveToNext());
        }

        cursor.close();
        audioAdapter=new AudioAdapter(context,audioInfos);

        recyclerView.setAdapter(audioAdapter);
}

例如

     String fullpath = trackcursor.getString(trackcursor.getColumnIndex(MediaStore.Audio.Media.DATA))

if(fullpath.contains(Environment.getExternalStorageDirectory(){
// you have the internal sdcard
} 

在您的代码中:

        if (cursor!=null){
        if (cursor.moveToFirst()){
            do {
                String name = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
                String duration = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DURATION));
                String sourceLocation = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));

                    if(sourceLocation.contains(Environment.getExternalStorageDirectory(){
    // you have the internal sdcard
     AudioInfo audioInfo=new AudioInfo(name,duration,sourceLocation);
                audioInfos.add(audioInfo);
    } 

            }while (cursor.moveToNext());
        }

        cursor.close();
        audioAdapter=new AudioAdapter(context,audioInfos);
        recyclerView.setAdapter(audioAdapter);
}
