Android View.getDrawingCache returns null, only null

Question

Would anyone please try to explain to me why

public void addView(View child) {
  child.setDrawingCacheEnabled(true);
  child.setWillNotCacheDrawing(false);
          


        

Answer 1

@cV2 and @nininho's answers both work for me.

One of the other reasons that i found out the hard way was that the view that i had was generating a view that has width and height of 0 (i.e. imagine having a TextView with a string text of an empty string). In this case, getDrawingCache will return null, so just be sure to check for that. Hope that helps some people out there.
