Tab change listener android

Question

My HomeActivity extends AppCompatActivity that uses 2 tabs.

public class HomeActivity extends AppCompatActivity {

    private SectionsPagerAdapter mSectionsPagerAdapter;
    private TabLayout tabLayout;
    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        ...
        mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
        tabLayout = (TabLayout) findViewById(R.id.tabs);
        tabLayout.setupWithViewPager(mViewPager);
    }

    ...

How to listen to tab change event? Let me know if I need to add any more code for clarity.

Answer 1

You can use TabLayout.OnTabChangeListener:

TabLayout tabLayout = new TabLayout(this);
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
    @Override
    public void onTabSelected(TabLayout.Tab tab) {
        //do stuff here
    }

    @Override
    public void onTabUnselected(TabLayout.Tab tab) {

    }

    @Override
    public void onTabReselected(TabLayout.Tab tab) {

    }
});

Hope it help.
