Use cases in the project

The project requires that watermarks be added to all pages, in which case the watermark layout can be set as the root layout in baseactivity

Foreground color style:

Watermark Layout Markframelayout

When you draw a watermark, you can choose to draw the foreground color on ondrawforeground (above all views), or you can choose to draw a background color on onDraw (it will be obscured by all view backgrounds).
If you need to use a watermark layout that inherits from other layout , simply change the inherited class to relativelayout or linearlayout . Nothing else needs to be changed.
