    copied!<p>From <a href="https://developer.android.com/training/basics/actionbar/adding-buttons.html" rel="nofollow">https://developer.android.com/training/basics/actionbar/adding-buttons.html</a>:</p> <p><strong>Specify the Actions in XML</strong></p> <p>All action buttons and other items available in the action overflow are defined in an XML menu resource. To add actions to the action bar, create a new XML file in your project's res/menu/ directory.</p> <p>Add an element for each item you want to include in the action bar. For example:</p> <pre><code>res/menu/main_activity_actions.xml &lt;menu xmlns:android="http://schemas.android.com/apk/res/android" &gt; &lt;!-- Search, should appear as action button --&gt; &lt;item android:id="@+id/action_search" android:icon="@drawable/ic_action_search" android:title="@string/action_search" android:showAsAction="ifRoom" /&gt; &lt;!-- Settings, should always be in the overflow --&gt; &lt;item android:id="@+id/action_settings" android:title="@string/action_settings" android:showAsAction="never" /&gt; &lt;/menu&gt; </code></pre> <p><strong>Add the Actions to the ActionBar</strong></p> <pre><code>@Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu items for use in the action bar MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.main_activity_actions, menu); return super.onCreateOptionsMenu(menu); } </code></pre> <p><strong>Respond to Action Buttons</strong></p> <pre><code>@Override public boolean onOptionsItemSelected(MenuItem item) { // Handle presses on the action bar items switch (item.getItemId()) { case R.id.action_search: openSearch(); return true; case R.id.action_settings: openSettings(); return true; default: return super.onOptionsItemSelected(item); } } </code></pre>
