How to Create ActionBar Menu Items in Android

In this article we will learn to create an application which add action items and menu items to action bar.

When we use ActionBar in the application , few important points are to be remember as follows:

1. Extend ActionBarActivity or AppCompatActivity instead of Activity,
   
   public class MainActivity extends ActionBarActivity{
   or
   public class MainActivity extends AppCompatActivity {
   
   
2. Select the right title for showAsAction for instance : “always”, “ifRoom”
   
   1. <menu xmlns:android="http://schemas.android.com/apk/res/android" Xmlns:app="http://schemas.android.com/apk/res-auto">
   2. <item android:id="@+id/action_user" android:icon="@drawable/ic_action_user" android:title="@string/action_user" app:showAsAction="ifRoom" /> ...
   3. </menu>
3. Define your Menu in Activity,
   
   1. @Override
   2. public boolean onCreateOptionsMenu(Menu menu)
   3. {
   4. // Inflate the menu; this adds items to the action bar if it is present.
   5. getMenuInflater().inflate(R.menu.menu_main, menu);
   6. return true;
   7. }
   8. @Override
   9. public boolean onOptionsItemSelected(MenuItem item)
   10. {
   11. // Handle action bar item clicks here. The action bar will
   12. // automatically handle clicks on the Home/Up button, so long
   13. // as you specify a parent activity in AndroidManifest.xml.
   14. switch (item.getItemId())
   15. {
   16. case R.id.action_user:
   17. Toast toast0 = Toast.makeText(getApplicationContext(), "User Profile", Toast.LENGTH_SHORT);
   18. toast0.show();
   19. return true;
   20. case R.id.search:
   21. Toast toast00 = Toast.makeText(getApplicationContext(), "Search", Toast.LENGTH_SHORT);
   22. toast00.show();
   23. return true;
   24. case R.id.action_settings:
   25. Toast toast = Toast.makeText(getApplicationContext(), "Action Settings", Toast.LENGTH_SHORT);
   26. toast.show();
   27. return true;
   28. case R.id.help_center:
   29. Toast toast1 = Toast.makeText(getApplicationContext(), "Help Center", Toast.LENGTH_SHORT);
   30. toast1.show();
   31. return true;
   32. case R.id.Rating:
   33. Toast toast3 = Toast.makeText(getApplicationContext(), "Rating", Toast.LENGTH_SHORT);
   34. toast3.show();
   35. return true;
   36. case R.id.More:
   37. Toast toast2 = Toast.makeText(getApplicationContext(), "More", Toast.LENGTH_SHORT);
   38. toast2.show();
   39. return true;
   40. default:
   41. return super.onOptionsItemSelected(item);
   42. }
   43. }
