How to measure layout performance?

I need to get some objective measures that screen renders faster. Tell me, please, how to measure the time of calculating the size of layout views and their rendering.

I tried to use hierarchyviewer, but it doesn't work properly in my case. It shows zeros for most of views.

I didn't try it before, but I think you can extend your Layout parent and override onMeasure() like this:

@override onMeasure (int widthMeasureSpec, int heightMeasureSpec) {
 float start=(float) System.currentTimeMillis();
 super.onMeasure (widthMeasureSpec, heightMeasureSpec);
 Log.i("ElapsedTime",String.valueOf(((float)System.currentTimeMillis())-start));
}

Then use this custom Layout as the root for your layout. You can do this for each View if you want to calculate them separately.
