  <p>My ActionBar code:</p>
  
  <pre><code>@Override
  public boolean onCreateOptionsMenu(Menu menu){
      MenuInflater inflater = getMenuInflater();
      inflater.inflate(R.menu.main, menu);
  
      this.getSupportActionBar().setDisplayShowCustomEnabled(true);
      this.getSupportActionBar().setDisplayShowTitleEnabled(false);
  
      this.getSupportActionBar().setDisplayHomeAsUpEnabled(true);
      this.getSupportActionBar().setHomeButtonEnabled(true);
  
      LayoutInflater inflator = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
      View v;
  
      if(!searchView){
          v = inflator.inflate(R.layout.action_textview, null);
          ((TextView) v.findViewById(R.id.titleText)).setText(actionTitle);
          menu.getItem(0).setVisible(true);
          menu.getItem(2).setVisible(true);
          mainMenu = menu;
  
      }else{
          v = inflator.inflate(R.layout.action_searchview, null);
          actionSearch = (EditText) v.findViewById(R.id.searchText);
          actionSearch.setOnEditorActionListener(new OnEditorActionListener() {
              @Override
              public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
                  int result = actionId &amp; EditorInfo.IME_MASK_ACTION;
                  switch(result) {
                  case EditorInfo.IME_ACTION_DONE:
                  case EditorInfo.IME_ACTION_NEXT:
                  case EditorInfo.IME_ACTION_GO:
                  case 0:
                      ((InputMethodManager)getSystemService(INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(actionSearch.getWindowToken(), 0);
                      String temp = actionSearch.getText().toString();
                      searchFor(temp);
                      break;
                  }
                  return true;
              }
          });
          actionSearch.requestFocus();
          menu.getItem(0).setVisible(false);
          menu.getItem(2).setVisible(false);
      }
      this.getSupportActionBar().setCustomView(v);        
  
      return super.onCreateOptionsMenu(menu);
