如何在TabLayout android中的活动中获取tab click事件

前端之家收集整理的这篇文章主要介绍了如何在TabLayout android中的活动中获取tab click事件前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
这是我的活动中onCreate函数的实现.我需要动态创建标签.为简单起见,我制作了两个标签.
public class ActivityProductList extends AppCompatActivity {

    private android.support.v7.widget.SearchView searchView = null;
    private RecyclerView recyclerView;
    MyAdapter adapter;
    List<ParentListItem> parentListItems = new ArrayList<>();
    List<ParentListItem> originalProductList = new ArrayList<>();
    String query = null;
    int categoryId = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_products_final);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setTitle("PRODUCTS");
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);

        //ViewPager viewPager = (ViewPager) findViewById(R.id.pager);

        TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
        tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
        //setupViewPager(viewPager);
        //tabLayout.setupWithViewPager(viewPager);
        //viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

        searchView = (android.support.v7.widget.SearchView) findViewById(R.id.searchView);
        searchView.setIconified(false);
        searchView.onActionViewExpanded();
        searchView.clearFocus();
        searchView.setOnQueryTextListener(new android.support.v7.widget.SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {
                if (adapter != null)
                    filterData(query);
                return false;
            }

            @Override
            public boolean onQueryTextChange(String query) {
                if (adapter != null)
                    filterData(query);
                return false;
            }
        });

    }
}

我想在点击选项卡时更改编辑文本值. editText处于同一活动中.

如何在活动中获得Tab click事件?

解决方法

您可以使用onTabSelected侦听器
tabLayout.addOnTabSelectedListener(new OnTabSelectedListener() {
        @Override
        public void onTabSelected(Tab tab) {
             switch(tab.getPosition()) {
                 case 0:
                  ....
             }
        }

附:不推荐使用setOnTabSelectedListener,请改用addOnTabSelectedListener
