java - Custom View Width -

-

i've created class custom view, , overrode onmeasure method show next. when call getter width , height, returns 0. why happen?

@override     protected void onmeasure(int widthmeasurespec, int heightmeasurespec){         super.onmeasure(widthmeasurespec, heightmeasurespec);         int parentwidth = measurespec.getsize(widthmeasurespec);         int parentheight = measurespec.getsize(heightmeasurespec);         this.setmeasureddimension(parentwidth, parentheight);    }

the getwidth() , getheight() values available after first full layout pass (onmeasure -> onlayout) if need access values in between use getmeasuredwidth() , getmeasuredheight()
