Question

在 Android 中如何在列表视图中显示带有缩略图的音频文件？

Answer 1

这里是从存储中获取音频的代码-

public class SongsManager{
// SDCard Path

private ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
Cursor cursor;
String[] projection = { MediaStore.Audio.Media.ALBUM_ID,
        MediaStore.Audio.Media.DISPLAY_NAME, MediaStore.Audio.Media.DATA,MediaStore.Audio.Media.ARTIST,
        MediaStore.Audio.Media.DURATION

};

@SuppressWarnings("deprecation")
public void getCursor(Activity context) {

    cursor = context.managedQuery(
            MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, projection,
            selection, null, null);

}

public ArrayList<HashMap<String, String>> getPlayList() {

    while (cursor.moveToNext()) {
        HashMap<String, String> song = new HashMap<String, String>();
        song.put("ID", cursor.getString(0));
        song.put("songTitle", cursor.getString(1));
        song.put("songPath", cursor.getString(2));
        song.put("Artist", cursor.getString(3));
        song.put("Duration", cursor.getString(4));
        songsList.add(song);
    }
    // return songs list array
    return songsList;
}

在 ListAdapter getview 方法中使用音频 id 获取音频拇指的代码

Uri sArtworkUri = Uri
                .parse("content://media/external/audio/albumart");
        Uri uri = ContentUris.withAppendedId(sArtworkUri,
                Long.parseLong(songsList.get(position).get("ID")));
        songimage.setImageURI(uri);
