This is an example of an android open screen layout that can be used to load AD images and a countdown layout. LayoutParams is set in the program, and the proportion of extra space is divided into 5 out of 6. The specific weight proportion can be defined according to the user's own requirements, and the AD image and relevant Android code can be asynchronously loaded.
The specific implementation code is as follows:
