如何在Android App中获取设备存储中的所有视频

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

String[] projection = { MediaStore.Video.Media._ID, MediaStore.Video.Media.DATA, MediaStore.Video.Media.DISPLAY_NAME };
String selection = null;
String[] selectionArgs = null;
String sortOrder = null;

Cursor cursor = getContentResolver().query(
    MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
    projection,
    selection,
    selectionArgs,
    sortOrder
);

if (cursor != null) {
    while (cursor.moveToNext()) {
        String videoId = cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media._ID));
        String videoPath = cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media.DATA));
        String videoName = cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media.DISPLAY_NAME));

        // 处理视频文件信息，可以将其添加到列表或进行其他操作
    }
    cursor.close();
}
