Answer 1

查询MediaStore内容提供者

一个例子可以是

public static void printNamesToLogCat(Context context) {
    Uri uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
    String[] projection = { MediaStore.Video.VideoColumns.DATA };
    Cursor c = context.getContentResolver().query(uri, projection, null, null, null);
    int vidsCount = 0;
    if (c != null) {
        vidsCount = c.getCount();
        while (c.moveToNext()) {
            Log.d("VIDEO", c.getString(0));
        }
        c.close();
    }
}
