目前我正在通过歌曲标题从 MediaStore 获取歌曲 ID:

long id = 0;
    ContentResolver cr = context.getContentResolver();

    Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection = MediaStore.Audio.Media.TITLE;
    String[] selectionArgs = {songTitle};
    String[] projection = {MediaStore.Audio.Media._ID};
    String sortOrder = MediaStore.Audio.Media.TITLE + " ASC";

    Cursor cursor = cr.query(uri, projection, selection, selectionArgs, sortOrder);

    if (cursor != null) {
        while (cursor.moveToNext()) {
            int idIndex = cursor.getColumnIndex(MediaStore.Audio.Media._ID);
            id = Long.parseLong(cursor.getString(idIndex));
        }
    }
    return id;

仅当标题不为空时才有效。
有没有直接从mp3文件的路径直接从MediaStore获取歌曲ID的方法?

最佳答案

自从找到解决方案后,我将回答我自己的问题。
解决方案是用 DATA 替换 TITLE,因为 DATA 表示 MediaStore 中媒体文件的路径。

public static long getSongIdFromMediaStore(String songPath, Context context) {
    long id = 0;
    ContentResolver cr = context.getContentResolver();

    Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
    String selection = MediaStore.Audio.Media.DATA;
    String[] selectionArgs = {songPath};
    String[] projection = {MediaStore.Audio.Media._ID};
    String sortOrder = MediaStore.Audio.Media.TITLE + " ASC";

    Cursor cursor = cr.query(uri, projection, selection + "=?", selectionArgs, sortOrder);


    Log.d(Constants.LOG_TAG, songPath);
    if (cursor != null) {
        while (cursor.moveToNext()) {
            int idIndex = cursor.getColumnIndex(MediaStore.Audio.Media._ID);
            id = Long.parseLong(cursor.getString(idIndex));
        }
    }
    return id;
}
