Question

I have a custom home icon for my app and I want it to align all the way to the left of the actionbar, so that it\'s touching the edge of the screen. Is this possible, and if

I finally managed to get this. You need to use a custom actionbar view. It's actually quite easy:

(This is using ActionbarSherlock, it should work with the stock compat library also...)

• First in your res/values/themes.xml, set the actionbar display options to "custom":

  showCustom
  

• Then create a file called res/layout/actionbar_layout.xml and place in it something like:

• Next, in your activity code add the following:

  View mActionCustomView = getSherlockActivity().getLayoutInflater()
      .inflate(R.layout.actionbar_layout, null);
  getSherlockActivity().getSupportActionBar().setCustomView(
          mActionCustomView);
  
  ImageView homeIcon = (ImageView)mActionCustomView
      .findViewById(R.id.home_icon);
  int abHeight = getSherlockActivity().getSupportActionBar()
      .getHeight();
  homeIcon.setLayoutParams(new RelativeLayout.LayoutParams(
              abHeight, abHeight));
  

That's basically it! Let me know if there's anything I left out. There are some nice benefits of having a customisable actionbar view, just stick to the basics and it will look great.
