Full-screen fragment to fragment transition displayed main activity during fragment transition

Question

In my android application, I had one main activity(ieHome) and two full-screen fragments. I can access theses three using Navigation Drawer. These two fragments act as the separate screen but actually its top on main activity. In my case, I clicked the first fragment then I clicked the second fragment. During this time, I closed the first fragment and displayed the second fragment. But, main activity screen was now displayed one second during fragment transition.

 @SuppressWarnings("StatementWithEmptyBody") @Override public boolean onNavigationItemSelected(MenuItem item) { fragmentTransaction = getSupportFragmentManager().beginTransaction(); fragmentTransaction.setCustomAnimations(R.anim.slide_in, R.anim.slide_out); if(!item.isChecked()) getSupportFragmentManager().popBackStackImmediate(null, POP_BACK_STACK_INCLUSIVE); item.setChecked(true); if (previousMenuItem != item.getItemId()) { if (item.getItemId() == R.id.fragment_two) { initialiseFragmentTwo(); } else if (item.getItemId() == R.id.nav_main_activity) { getSupportFragmentManager(). popBackStackImmediate(null, POP_BACK_STACK_INCLUSIVE); getSupportActionBar().setTitle(R.string.app_name); } else if(item.getItemId() == R.id.nav_fragment_one){ initialiseFragmentOne(); } } previousMenuItem = item.getItemId(); DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); if (drawer != null) { drawer.closeDrawer(GravityCompat.START); } return true; }

Instead of using POP_BACK_STACK_INCLUSIVE try to use replace

    public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int id = item.getItemId();
    Fragment fragment = null;
    Class fragmentClass = null;
    if (id == R.id.nav_camera) {
        fragmentClass = FragmentOne.class;
    } else if (id == R.id.nav_gallery) {
        fragmentClass = FragmentTwo.class;
    } else if (id == R.id.nav_slideshow) {
        fragmentClass = FragmentOne.class;
    } else if (id == R.id.nav_manage) {
        fragmentClass = FragmentTwo.class;
    } else if (id == R.id.nav_share) {
        fragmentClass = FragmentOne.class;
    } else if (id == R.id.nav_send) {
        fragmentClass = FragmentTwo.class;
    }
    try {
        fragment = (Fragment) fragmentClass.newInstance();
    } catch (Exception e) {
        e.printStackTrace();
    }
    FragmentManager fragmentManager = getSupportFragmentManager();
    fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}
