         mFieldPopup.setAccessible(true); 
         MenuPopupHelper mPopup = (MenuPopupHelper) mFieldPopup.get(popup); 
         mPopup.setForceShowIcon(true);

showPopUpMenu(View); pass View wo möchten Sie dieses Popup anhängen?

void showPopUpMenu(View anchor) { 
     PopupMenu popup = new PopupMenu(MainActivity.this, anchor); 
     //Inflating the Popup using xml file 
     popup.getMenuInflater().inflate(R.menu.popup_menu, popup.getMenu()); 

     //registering popup with OnMenuItemClickListener 
     popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { 
      public boolean onMenuItemClick(MenuItem item) { 
       Toast.makeText(MainActivity.this, "You Clicked : " + item.getTitle(), Toast.LENGTH_SHORT).show(); 
       return true; 
      }
