I was just building some UI in xml, and Lint gave me a warning and said to set android:baselineAligned to false to improve performance in ListView.

The docs for the Lint changes that added this warning say

Layout performance: Finds LinearLayouts with weights where you should
set android:baselineAligned=”false” for better performance, and also
finds cases where you have nested weights which can cause performance
problems.

Can somebody explain why this improves performance, specifically when weight is involved?

    By setting android:baselineAligned="false" , you’re preventing the extra work your app’s layout has to do in order to Align its children’s baselines; which can obviously increase the performance. (Fewer unnecessary operations on UI => Better performance)
