Popup window running as background image in navigation drawer Activity

Question

[Image sample][1]I have popup screen implemented in my navigation drawer activity. Problem is that popup window is showing like background image of activity. What i want to popup come visible in foreground when Activity starts and after 3 seconds dismiss.

Here is my activity:

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

    setSupportActionBar(toolbar);

    drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.setDrawerListener(toggle);

    toggle.syncState();    

    try {
        LayoutInflater inflater1 = (LayoutInflater) MainActivity.this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        // Inflate the view from a predefined XML layout
        View layout = inflater1.inflate(R.layout.activity_pop_up,
                (ViewGroup) findViewById(R.id.relativeLayoutZaFragment));
        // create a 300px width and 470px height PopupWindow
        pw = new PopupWindow(layout, 300, 470, true);
        // display the popup in the center
        pw.showAtLocation(layout, Gravity.CENTER, 0, 0);
    } catch (Exception e) {
        e.printStackTrace();
    }

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

    FragmentMainPage pocetnaFragment = new FragmentMainPage();
    FragmentManager fragmentManager = getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.relativeLayoutZaFragment, pocetnaFragment, "1");
    fragmentTransaction.commit();

    getSupportActionBar().setTitle("Auto magazin");

    ActionBar.LayoutParams p = new ActionBar.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
    p.gravity = Gravity.LEFT;

    view = getLayoutInflater().inflate(R.layout.action_bar, null);

    ActionBar.LayoutParams params = new ActionBar.LayoutParams(
            ActionBar.LayoutParams.WRAP_CONTENT,
            ActionBar.LayoutParams.MATCH_PARENT,
            Gravity.LEFT);

    TextView Title = (TextView) view.findViewById(R.id.actionbar_title);

    Title.setText("Auto magazin");

    getSupportActionBar().setCustomView(view,params);
    getSupportActionBar().setDisplayShowCustomEnabled(true); //show custom title
    getSupportActionBar().setDisplayShowTitleEnabled(false); //hide the default title
}

boolean doubleBackToExitPressedOnce = false;

@Override
public void onBackPressed() {
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    assert drawer != null;

    if (drawer.isDrawerOpen(GravityCompat.START)) {
        drawer.closeDrawer(GravityCompat.START);
        return;
    }
    else if (doubleBackToExitPressedOnce) {
        super.onBackPressed();
        return;
    }

    this.doubleBackToExitPressedOnce = true;
    Toast.makeText(this, "Pritisnite još jednom za izlaz", Toast.LENGTH_SHORT).show();

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            doubleBackToExitPressedOnce = false;
        }
    }, 2000);
}

@Override

{
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);

    return true;

Answer 1

What you're seeing is not actually your PopupWindow. That inflate() call is attaching the inflated View directly to the relativeLayoutZaFragment, and the Fragment is being added on top of it. Then, since that View is already attached to a parent, the PopupWindow is throwing an Exception, and is never shown.

Change the second argument in the inflate() call to null:

View layout = inflater1.inflate(R.layout.activity_pop_up, null);

And pass the RelativeLayout that's in the Activity to showAtLocation(), instead of the inflated layout:

pw.showAtLocation(findViewById(R.id.relativeLayoutZaFragment‌​), Gravity.CENTER, 0, 0);

Additionally, since you're doing this in onCreate(), you'll need to defer showing the PopupWindow momentarily, or you'll get that WindowManager$BadTokenException. You can do that by putting the showAtLocation() call in a Runnable, and posting that to a View. For example:

final View rl = findViewById(R.id.relativeLayoutZaFragment‌);
rl.post(new Runnable() {
    @Override
        public void run() {
            pw.showAtLocation(rl, Gravity.CENTER, 0, 0);
        }
    }
);
