Добавить Spinner as Tab с помощью библиотеки поддержки дизайна

Question

Я использую библиотеку поддержки дизайна для создания вкладок. Я добавил панель просмотра панели инструментов и вкладки.

Я хочу добавить виджет Spinner как один из TAB с поддержкой библиотеки дизайна.

Можно ли добавить Spinner в качестве одного из элементов TAB? Можете ли вы привести пример?

Answer 1

 TabLayout tabLayout = findViewById(R.id.tab_layout); 
     TabLayout.Tab tab = tabLayout.newTab(); 
     Spinner spinner = new Spinner(MainActivity.this); 
//  spinner.setAdapter(new SimpleAdapter()); 
     tab.setCustomView(spinner); 
     tabLayout.addTab(tab);
