Would anyone please try to explain to me why
public void addView(View child) {
child.setDrawingCacheEnabled(true);
child.setWillNotCacheDrawing(false);
child.setWillNotDraw(false);
child.buildDrawingCache();
if(child.getDrawingCache() == null) { //TODO Make this work!
Log.w("View", "View child's drawing cache is null");
}
setImageBitmap(child.getDrawingCache()); //TODO MAKE THIS WORK!!!
}
ALWAYS logs that the drawing cache is null, and sets the bitmap to null?
Do I have to actually draw the view before the cache is set?
Thanks!
