Here is an example of one of my traceviews, there's a lot of onMeasures being called byTextView and RelativeLayout, but there is only 20 getview calls on my listadapter. I understand that there are other parts in my layout that might use these, but the rest of the layout is simple. How can I minimize this to improve my performance?
