title: What is the private field name of actionbar context view ?
body: <p>A Hello ,,,
  I'm using robotium framework for testing android apps and I used Robotium-actionbarsherlock extension to perform clicks on contextual actionbar menu item ... </p>
  
  <p>Here's the function I'm using ,,,</p>
  
  <pre><code>public void clickOnActionModeOverflowMenuItem(String text) {
      Activity activity = solo.getCurrentActivity();
      Log.d("aaaa", activity.toString());
      if (!(activity instanceof SherlockFragmentActivity)) {
              throw new IllegalStateException("This method should be called only in SherlockFragmentActivity.");
      }
  
      ActionBarContextView actionBarContextView = null;
  
      try {
              ActionBarSherlock actionBarSherlock = (ActionBarSherlock) invokePrivateMethodWithoutParameters(
                  SherlockFragmentActivity.class, "getSherlock", activity);
              Log.d("eeee", actionBarSherlock.toString());
              actionBarContextView = (ActionBarContextView) getPrivateField("mActionModeView", actionBarSherlock);
              Log.d("dddd", actionBarContextView.toString());
  
      } catch (Exception ex) {
              Log.d(LOG_TAG, "Can not find methods to invoke action mode overflow button.");
      }
  
      if (actionBarContextView == null) {
              Assert.fail("Contextual actionbar is not shown.");
      }
  
      actionBarContextView.showOverflowMenu();
      sleeper.sleep();
      clicker.clickOnText(text, false, 1, true, 0);
  }
  </code></pre>
  
  <p>So, I'm asking about this line ..</p>
  
  <pre><code>actionBarContextView = (ActionBarContextView) getPrivateField("mActionModeView", actionBarSherlock);
  </code></pre>
  
  <p>How can I know the private field name ?
  As the function fails and throws the assertion fail of null actionBarContextView ...</p>
