如何访问Android Q中的所有图片？

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

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

try (Cursor cursor = getContentResolver().query(
        MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
        projection,
        selection,
        selectionArgs,
        sortOrder)) {
    int idColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);
    int nameColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DISPLAY_NAME);

    while (cursor.moveToNext()) {
        long id = cursor.getLong(idColumn);
        String name = cursor.getString(nameColumn);
        Uri contentUri = ContentUris.withAppendedId(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, id);

        // 处理每张图片的逻辑
        // ...
    }
}
