Android bottom menu bar implementation
After reading ViewPager recently, I came up with the idea of making an Demo like this. Of course, I also referred to the grid menu in the examples of experts. At the beginning, I planned to use the custom imgBtn, but I found it difficult to put it in the pager TAB for typesetting, so I had better choose GridView, which is simple and practical
1. Host interface xml
activity_main.xml
The three tabs in ViewPager are xml
view_main.xml,view_set.xml,view_utils.xml
This is TAB 1view_main.xml. The last two are like this one
Finally, there is an GirdView adapter, xml
So much for the xml layout

The three tabs in ViewPager are xml
view_main.xml,view_set.xml,view_utils.xml

This is TAB 1view_main.xml. The last two are like this one
Finally, there is an GirdView adapter, xml
