Measure, layout, and drawing time in the Hierarchyviewer

Question

What is the difference between measurement, layout, and drawing time in the Android Hierarchyviewer? There is a good article on Android developers, but I cannot find any information related to the actual values ​​of these three different time values ​​... Can someone explain the difference to me? Thanks.

There are 3 steps in the rendering process. First, your opinion is measured, it’s just the width and height. Then the controls go through the layout, it basically just shows all the views where they are inside the dimensions. And finally, everything is drawn. This is where the controls are actually drawn on the canvas. So this is probably what you are looking at.
