Using navigationView with tabLayout

Question

So I\'ve recently been working on updating my app to use the new material design support library. My application has one main activity with a drawerLayout and navigation vie

Answer 1

You can do it like this. I have checked by doing it myself and it works very well

Step 1 : Create a layout of your main activity like this

Step 2 :

In your activity you need to set onpagechangelistener on your viewpager:

 viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
  @Override
  public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

  }

  @Override
  public void onPageSelected(int position) {
        if(position ==0){
          tabLayout.setVisibility(View.GONE);
        }else{
          tabLayout.setVisibility(View.VISIBLE);
        }
  }

  @Override
  public void onPageScrollStateChanged(int state) {

  }
});

After this you need to add viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

Step 3 :

This is how you can make your adapter for viewpager :

public class WiFiPagerAdapter extends FragmentPagerAdapter { private final List registeredFragments = new ArrayList<>();

public WiFiPagerAdapter(final FragmentManager fm) {
  super(fm);
}

@Override
public Fragment getItem(final int pos) {
  Fragment fragment;
  fragment = WiFiFragment.newInstance(pos);
  registeredFragments.add(pos, fragment);
  return fragment;
}

@Override
public int getCount() {
  return tabLayout.getTabCount();
}

public List getRegisteredFragmentsList() {
  return registeredFragments;
}

@Nullable
public Fragment getRegisteredFragment(final int position) {
  final Fragment wr = registeredFragments.get(position);
  if (wr != null) {
    return wr;
  } else {
    return null;
  }
}

@Override
public void notifyDataSetChanged() {
  super.notifyDataSetChanged();
  for (int i = 0; i < registeredFragments.size(); i++) {
    WiFiFragment wiFiFragment = ((WiFiFragment) registeredFragments.get(i));
    wiFiFragment.setWiFiFragmentRecyclerViewAdapter();
  }
}

}
