title: Back Arrow in Action bar Sherlock is not displaying
body: <p>In my project I have used action bar sherlock library. I want to make back button in action bar I used following code</p>
  
  <pre><code>getSupportActionBar().setHomeButtonEnabled(true);
  </code></pre>
  
  <p><strong>And</strong></p>
  
  <pre><code>@Override
      public boolean onOptionsItemSelected(MenuItem item) {
          switch (item.getItemId()) {
  
          case android.R.id.home:
               finish();
               break;
  
          default:
              return super.onOptionsItemSelected(item);
          }
          return false;
      }
  </code></pre>
  
  <p>Every thing is working fine, but back Arrow (to the left of icon) is not displaying. I want to show Back Arrow also. Can anyone tell me what I am doing wrong.</p>
