Although this is a simple situation, we only need to understand the principle. No matter how complex the situation is, it can be easily solved. We only need to divide each layout into one type and load different layouts in our customized adapter according to the type we distinguish. The code is as follows:

Is it easy to find? Finally, I'll post all the code together.
