Show hide fragment in android

Solution 1:

Don't mess with the visibility flags of the container - FragmentTransaction.hide/show does that internally for you.

So the correct way to do this is:

FragmentManager fm = getFragmentManager();
fm.beginTransaction()
          .setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out)
          .show(somefrag)
          .commit();

OR if you are using android.support.v4.app.Fragment

 FragmentManager fm = getSupportFragmentManager();
 fm.beginTransaction()
          .setCustomAnimations(android.R.anim.fade_in, android.R.anim.fade_out)
          .show(somefrag)
          .commit();

Solution 2:

In addittion, you can do in a Fragment (for example when getting server data failed):

 getView().setVisibility(View.GONE);

Solution 3:

Hi you do it by using this approach, all fragments will remain in the container once added initially and then we are simply revealing the desired fragment and hiding the others within the container.

// Within an activity
private FragmentA fragmentA;
private FragmentB fragmentB;
private FragmentC fragmentC;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if (savedInstanceState == null) {
        fragmentA = FragmentA.newInstance("foo");
        fragmentB = FragmentB.newInstance("bar");
        fragmentC = FragmentC.newInstance("baz");
    }
}


// Replace the switch method
protected void displayFragmentA() {
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    if (fragmentA.isAdded()) { // if the fragment is already in container
        ft.show(fragmentA);
    } else { // fragment needs to be added to frame container
        ft.add(R.id.flContainer, fragmentA, "A");
    }
    // Hide fragment B
    if (fragmentB.isAdded()) { ft.hide(fragmentB); }
    // Hide fragment C
    if (fragmentC.isAdded()) { ft.hide(fragmentC); }
    // Commit changes
    ft.commit();
}
