Question

I got two views which are equally distributed on my main layout.But my two views in tern have nested childs which are again equally spaced.I am using nested layout weight’s which is working fine. Whether nested weights effects the performance.What is the work around for this?

Answer 1

Every view — or worse, every layout manager — that you add to your
application comes at a cost: initialization, layout and drawing become
slower. The layout pass can be especially expensive when you nest
several LinearLayout that use the weight parameter, which requires the
child to be measured twice.

Refer: http://developer.android.com/resources/articles/layout-tricks-efficiency.html

You can use a RelativeLayout in most cases to avoid such expensive measurements. In a RelativeLayout, views are aligned with their parent, with the RelativeLayout itself, or with other views.

To clearly understand how the views are positioned with respect to each other, a wireframe of the layout can be captured by using HierarchyViewer perspective of Android SDK.
