我正在github https://github.com/Zomato/AndroidPhotoFilters上使用zomato库。当我在应用程序中实现该库时，它可以正常工作，但问题是，当我单击缩略图（过滤器图像在快照中看到）时，它崩溃并且不对图像应用过滤器（从过滤器图像上方查看大图像）在imageview中，我已从图库中加载，我想在加载的图像上应用缩略图（过滤器图像）。您可以在上面的链接上查看完整的库，但是onthumbnailClick方法中出现了问题。.有人可以帮助我吗...谢谢
@Override
public void onThumbnailClick(Filter filter) {
image_view = findViewById(R.id.place_holder_ImageView);
Bitmap abc = filter.processFilter(testbitmap);
image_view.setImageBitmap(abc);
}
