Answer 1

You have to first get all images from gallery in you activity then have to set the list of images to RecyclerView

Use below method to get all all images-

    private ArrayList<String> getAllShownImagesPath(Activity activity) {
        Uri uri;
        Cursor cursor;
        int column_index_data, column_index_folder_name;
        ArrayList<String> listOfAllImages = new ArrayList<String>();
        String absolutePathOfImage = null;
        uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

        String[] projection = { MediaColumns.DATA,
                MediaStore.Images.Media.BUCKET_DISPLAY_NAME };

        cursor = activity.getContentResolver().query(uri, projection, null,
                null, null);

        column_index_data = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
        column_index_folder_name = cursor
                .getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME);
        while (cursor.moveToNext()) {
            absolutePathOfImage = cursor.getString(column_index_data);

            listOfAllImages.add(absolutePathOfImage);
        }
        return listOfAllImages;
    }

Now set the This list of images to RecyclerView Adapter.

Take this RecyclerView Example as an reffrence to set all gallery images.
