title: Toolbar Item Click
body: <p>I am using toolbar in my app. Toolbar layout looks like this. I add <code>imageButton</code> inside toolbar as menu item. (Is that is a problem?) As I am new to Toolbar I don't know if this is the right way.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/toolbar"
  android:layout_width="match_parent"
  android:layout_gravity="top"
  android:layout_height="@dimen/abc_action_bar_default_height_material"
  android:minHeight="?attr/actionBarSize"
  android:gravity="right"
  android:background="?attr/colorPrimaryDark"&gt;
  
  
  &lt;ImageButton
      android:src="@drawable/ic_action_social_share"
      android:layout_width="48dp"
      android:layout_height="48dp"
      android:layout_gravity="right"
      android:layout_marginRight="8dp"
      android:background="?selectableItemBackground"
      android:id="@+id/shareButton" /&gt;
  
  &lt;ImageButton
      android:src="@drawable/ic_tag"
      android:layout_width="48dp"
      android:layout_height="48dp"
      android:layout_gravity="right"
      android:layout_marginRight="8dp"
      android:background="?selectableItemBackground"
      android:id="@+id/tagButton" /&gt;
  
  &lt;ImageButton
      android:src="@drawable/ic_action_action_bookmark"
      android:layout_width="48dp"
      android:layout_height="48dp"
      android:layout_gravity="right"
      android:layout_marginRight="8dp"
      android:background="?selectableItemBackground"
      android:id="@+id/bookmarkButton" /&gt;
  
  &lt;/android.support.v7.widget.Toolbar&gt;
  </code></pre>
  
  <p>And in <code>onCreate</code>:</p>
  
  <pre><code>@Override
  protected void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
      setContentView(R.layout.newsdetail_activity);
      mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar);
      setSupportActionBar(mActionBarToolbar);
      ActionBar actionBar = getSupportActionBar();
      actionBar.setDisplayHomeAsUpEnabled(true);
      actionBar.setHomeButtonEnabled(true);
   }
  </code></pre>
  
  <p>And <code>onOptionItemSelected</code>:</p>
  
  <pre><code>@Override
  public boolean onOptionsItemSelected(MenuItem item) {
  
  
      switch (item.getItemId()) {
          case android.R.id.home:
              onBackPressed();
              break;
          case R.id.shareButton:
  
              Log.d(TAG, "SHARE BUTTON");
  
              break;
      }
      return true;
  }
  </code></pre>
  
  <p>The click on <code>shareButton</code> in toolbar is not firing. Can anyone tell the reason for this?</p>
