listview音频播放自定义路径

Question

这是音乐播放器光标;它的功能很好，它显示从sdcard到listview的所有歌曲，但我只想要特定的文件夹，如何在查询时添加自定义文件夹路径？

musicAdapter = new RecordPlayerAdapter（this）;

    Cursor musicCursor = getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, null, null, null);
    if (musicCursor != null && musicCursor.moveToFirst()) {
        do {
            musicAdapter.add(new RecordPlayerBridge(
                    musicCursor.getString(musicCursor.getColumnIndex(MediaStore.Audio.Media.TITLE)),
                    musicCursor.getLong(musicCursor.getColumnIndex(MediaStore.Audio.Media.DURATION)),
                    musicCursor.getString(musicCursor.getColumnIndex(MediaStore.Audio.Media.DATA))
            ));
        } while (musicCursor.moveToNext());
    }

Answer 1

您需要添加所需的文件夹作为查询参数

码：

Cursor musicCursor = getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, 
                MediaStore.Images.Media.DATA + " like ? ", 
                //Here in the query you add the desired folder for example iron_maiden folder.
                new String[] {"%iron_maiden%"},
                null);

我希望它能解决你的问题。
