如何在andorid中获取所有视频文件

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

String[] projection = { MediaStore.Video.Media.DATA, MediaStore.Video.Media.TITLE };

ContentResolver contentResolver = getContentResolver();
Uri uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
Cursor cursor = contentResolver.query(uri, projection, null, null, null);

if (cursor != null && cursor.moveToFirst()) {
    do {
        String filePath = cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media.DATA));
        String title = cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media.TITLE));
        // 处理视频文件信息
    } while (cursor.moveToNext());
}
