Want ActionBar's Up to mimic Back functionality, but have no way to ping it & menu layout doesn't reflect what I actually see

Issue

There are a few things I want to do, but I don't know if I did this right.

I simply created an Activity and declared its android:parentActivityName in the AndroidManifest.xml.

When I click on an item in my ListView from my first fragment in my ViewPager, it takes me to that activity. When I press the Back button on my phone, it takes me back to the exact state that the Fragment and the ViewPager were in. However, when I press the Up button in my ActionBar, I am taken back to the Fragment and ActionBar but it seems to reload everything. I have found answers for applying the Back functionality to the Up button, but for some reason I can't reference the Up button in anyway.

When I view my menu file corresponding to the top, all I see is:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      tools:context="com.unlock.gate.CommentsActivity">
    <item android:id="@+id/action_settings"
          android:title="@string/action_settings"
          android:orderInCategory="100"
          android:showAsAction="never"/>
</menu>

This is perplexing because I don't even see the three vertical dots representing the Settings but see the Up button. How do I alleviate this issue? Also, the label for this Activity is Comments. When I press the Up button, it seems to include the label in the highlighting. I would like these separated such that the Up button is by itself and the Label just sits there without being manipulated with the button.

Solution

public void onMenuItemPressed(MenuItem item){
  switch(item.getId)
  {
    case android.R.id.home :
         onBackPressed();
         ....
         return;
    ...
  }
}

You can override up button pressed like this.
