Как сделать gridView выпадающим меню?

Question

В моем приложении Android я хочу сделать выпадающий список gridView, и для этого я использовал несколько textView вместе с одним gridView, и onClick из этих textViews Я изменяю содержимое gridView и сделав его видимым ниже, нажал textView. Мое приложение работает нормально, но проблема, если пользователь нажимает на textView1, оно будет работать нормально, и после нажатия textView1, если пользователь нажимает на textView2, он должен дважды щелкнуть по нему, чтобы сделать gridView видимым. Я хочу, чтобы он был более плавным и работал в один клик.

Вот мой XML код активности:
