Trace: requestLayout() improperly called?

Question

Can anyone tell me how to fix the following trace:

W/View    (16810): requestLayout() improperly called by 
theme.effects.TopCenterImageView{41dc73f0 V.ED...         


        

Answer 1

I changed a child views layout params in the onLayout method AFTER calling super.onLayout(); That lead to a recursion:

Childlayout params changed -> parent view onRequestLayout() -> parent view onLayout -> childview params changed -> ...

Answer 2

As seen here, setScaleType will call requestLayout, but the constructor of ImageView already call it before. So it will cause the layout to have multiple requestLayout called, one during the layout pass. It's just a warning because at a small scale, it's not a problem.

You will find some good research in this thread (not the roboguice part though).
