ActionBar Design for Android 4

Implementation of Action Bar in Android version 4 (only above)

1. MyActivity.java

public class MyActivity extends Activity {

 public static Context con;
 public MyActivity() {
  con = MyActivity.this;
 }

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.my_activity);
  ActionBar actionbar = getActionBar();
  actionbar.setHomeButtonEnabled(true);
  actionbar.setDisplayShowTitleEnabled(false);
  actionbar.setLogo(R.drawable.logout);
  Drawable d = getResources().getDrawable(R.drawable.top_bar_logo);
  actionbar.setBackgroundDrawable(d);
  actionbar.setIcon(R.drawable.login_logo);
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  MenuInflater inflater = getMenuInflater();
  inflater.inflate(R.menu.menu_option, menu);
  return true;
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
  switch (item.getItemId()) {
  case R.id.menuitem_search:
   Toast.makeText(con, "search", Toast.LENGTH_SHORT).show();
   return true;
  case android.R.id.home:
   Toast.makeText(con, "Home", Toast.LENGTH_SHORT).show();
   return true;
  }
  return false;
 }
}

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/menuitem_search"
        android:icon="@drawable/bubble"
        android:showAsAction="ifRoom"
        android:title="search">
