Then, filter activities. In the layout, a GridView is used to display the options to be selected, and a button is used to click to return to the main activity and bring the selected value

Then there is the filter logic

The main state changes are still in the adapter

And the item layout

If you want to click the jump to select Activity and the button to be filtered, show that the state of the button that you selected before is selected. It is also very simple. As long as you cache the position after you select it, point it in to filter Activity, instantiate Adapter and use mAdapter.changeState (position). Just pass the position of the button you need to change the state
