title: how to deflate/hide(invisible) ViewStub from Menu (onOptionsItemSelected)?
body: <p>I keep getting NullPointerException trying to deflate or make invisible the ViewStub from my UI. I just wanted to be sure I am doing it right.</p>
  
  <p>I am inflating my ViewStub in onItemLongClick method of GalleryView by doing the following:</p>
  
  <pre><code>@Override
              public boolean onItemLongClick(AdapterView&lt;?&gt; arg0, View viu, int arg2,
                      long arg3) {
                  Toast.makeText(GalleryView.this, "New item added to Favorites", Toast.LENGTH_SHORT).show();
  
  
                  favsCount++;
  
                 //checking to see if ViewStub is already inflated or not
                  if(!stubvis){
                  stub = (ViewStub) findViewById(R.id.stub1);
                  stub.inflate();
                  stubvis = true;
                  trayUP = true;
                  }
  
                  return true;
              }
  
              });
  </code></pre>
  
  <p>and then in onPrepareOptionsMenu() I am adding the menu item based on the visibility of ViewStub. If inflated and visible, I create a menu item to hide it, otherwise, a menu item to show/make visible.</p>
  
  <pre><code>@Override
  
  public boolean onPrepareOptionsMenu(Menu menu) {
  
  menu.clear();
  
  
  if(trayUP) {
  
  menu.add(0, HIDETRAY, 0, "Hide Favorites Tray");
  
  } else {
  
  menu.add(0, SHOWTRAY, 0, "Show Favorites Tray");
  
  }
  
  return super.onPrepareOptionsMenu(menu);
  
  }
  </code></pre>
  
  <p>Next, in onOptionsItemSelected(), I am writing the two cases based on the menu item selection. Case 1 when the tray is not visible, so I make it visible. Case 2 when it is visible, so I hide it by doing the following:</p>
  
  <pre><code>@Override
  public boolean onOptionsItemSelected(MenuItem item) {
  
      switch (item.getItemId()) {
  
          case HIDETRAY:
  
              Log.v(TAG, "Hiding Favs Tray");
              findViewById(R.id.stub1).setVisibility(View.GONE);
              trayUP = false;
  
          case SHOWTRAY:
  
              Log.v(TAG, "Showing Favs Tray");
              findViewById(R.id.stub1).setVisibility(View.VISIBLE);
              trayUP = true;
  
          }
  
      return true;
  </code></pre>
  
  <p>}</p>
  
  <p>I know I am making a silly mistake somewhere. And my mind is too saturated to think straight at the moment. Need help :(</p>
  
  <p>Thanks,</p>
