How to get tab click event in activity in TabLayout android

This is implementation of onCreate function in my activity. I need to create the tabs dynamically. Here for simplicity i made 2 tabs.

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);
                retu false;
            }

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

    }
}

I want to change edit-text value on click on tabs. That editText is in same activity.
