getDrawingCache on Framelayout and its child returns empty bitmap












1















Found so many Questions on SO related to getDrawingCache but no one seems to give a workaround to my problem. the issue might be simple but I'm unable to figure it out because of my less expertise. I've looked into following threads,




  • Saving View bitmap with getDrawingCache gives a black image

  • Bitmap created from FrameLayout is black

  • Drawing over a view and all it's children


Nothing helps.



The problem is, I have a FrameLayout and 4 Children as small ImageViews in it. One ImageView is taking full width and height as FrameLayout and all other ImageViews are being drawn over it. I need the bitmap of that FrameLayout with all the ImageViews for further processing. Here is my code to get the bitmap,



public void method(){
mainFrame.setDrawingCacheEnabled(true);
Bitmap b = mainFrame.getDrawingCache();
}


Bitmap is not null but it is blank. It does not show any child ImageView.



How can I get the Bitmap of FrameLayout with all its children ?
