Basically, I have a view that needs to be split up into a 2x4 grid, with each section equal in size (i.e. each row would be 25% of the screen height, and each column would be 50% of the screen width).My approach was to use a horizontal LinearLayout with two inner LinearLayouts with a weight of 0.5 and then in each of those LinearLayouts set the weight of the children to 0.25 so that each one takes up 25% of the screen.Although this seems to work, this is apparently very bad for performance (see this thread for a reason why Why are nested weights bad for performance? Alternatives?)Are there any alternatives to achieve this? I have had a look around but I can't find a pure XML solution to this.See below a code example of how I have the LinearLayouts and their children setup<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android
