Question

基本上我想在android.i中更改音频文件的专辑封面，通过以下方法获取所有音频文件：

    private void loadAudio() {
    ContentResolver contentResolver = myContext.getContentResolver();

    Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection = MediaStore.Audio.Media.IS_MUSIC + "!= 0";
    String sortOrder = MediaStore.Audio.Media.TITLE + " ASC";
    Cursor cursor = contentResolver.query(uri, null, selection, null, sortOrder);

    if (cursor != null && cursor.getCount() > 0) {
        while (cursor.moveToNext()) {
            long thisId = cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Media._ID));
            String data = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));
            String title = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.TITLE));
            long albumId = cursor.getLong(cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM_ID));
            String artist = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST));
            final Uri ART_CONTENT_URI = Uri.parse("content://media/external/audio/albumart");
            Uri albumArtUri = ContentUris.withAppendedId(ART_CONTENT_URI, albumId);
            songList.add(new songModel(thisId, title,artist,albumArtUri,data,albumId));
        }
    }
    cursor.close();
}

我无法使用Mp3agic，因为它只处理.mp3文件。我想要的是从媒体商店删除相关音频的专辑封面的路径，并插入一个新的如下：

ContentResolver res = getContext().getContentResolver();
        InputStream in = null;
        try {
            in = res.openInputStream(Uri.parse(path));
        } catch (FileNotFoundException e) {
            albumartexists = false;
        }
        if (albumartexists)
        {
            Toast.makeText(getContext(), "file exists", Toast.LENGTH_SHORT).show();
            getContext().getContentResolver().delete(ContentUris.withAppendedId(Uri.parse("content://media/external/audio/albumart"),id), null, null);
        }
        ContentValues values = new ContentValues();
        values.put("album_id",id);
        values.put("_data",Environment.getExternalStorageDirectory() + "/Thumbnail/"+targetFileName);
        Uri newuri = res.insert(Uri.parse("content://media/external/audio/albumart"), values);
        if(newuri==null)
        {
            Toast.makeText(getContext(), "nwure is null", Toast.LENGTH_SHORT).show();
            getContext().getContentResolver().delete(ContentUris.withAppendedId(Uri.parse("content://media/external/audio/albumart"),id), null, null);
            newuri = getContext().getContentResolver().insert(Uri.parse("content://media/external/audio/albumart"), values);
        }

此代码适用于某些文件，而对于某些文件，当albumart随之更改时，会更改几首歌曲的albumart。我不知道错误在哪里。请帮帮我！不知道代码或其他什么问题。
