Ever wondering how a particular app structure their hierarchy of views? With the latest Android SDK(I’m using 21.01 currently) and Eclipse ADT plugin, you can finally do that!
1. Connect your phone, Open the app you are curious about. Switch to the DDMS perspective, See the little button over there? click on it.
2. The following screen will appear, you can now browse the view hierarchy just like a DOM tree which Web developers are familiar with.
What is does is basically dump a snapshot of the view in the current screen to the IDE. There’s quite a lot of information you can see in the “Node Detail” section, but you probably cannot reconstruct a layout XML in your own code by these info because It doesn’t show you some attributes like layout_width, layout_height, layout_weight etc. But it definitely tells you what types of views you need to build a particular layout.
