title: Android Toolbar Covering Content
body: <p>I am using the new toolbar and setting it as the supportActionBar.  My problem is that it is covering my content.</p>
  
  <p>Here is the code I am using to setup the toolbar.</p>
  
  <pre><code> public void setupNavBar() {
      mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar);
      if (mToolbar != null) {
          setSupportActionBar(mToolbar);
  
          mActionBar = getSupportActionBar();
          mActionBar.setDisplayShowHomeEnabled(true);
          mActionBar.setDisplayShowTitleEnabled(false);
      }
  }
  </code></pre>
  
  <p>The Styles:</p>
  
  <pre><code>    &lt;!-- Base application theme. --&gt;
  &lt;style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"&gt;
      &lt;!-- Customize your theme here. --&gt;
  &lt;/style&gt;
  
  &lt;style name="ToolBarStyle" parent=""&gt;
      &lt;item name="android:elevation"&gt;5dp&lt;/item&gt;
      &lt;item name="popupTheme"&gt;@style/ThemeOverlay.AppCompat.Light&lt;/item&gt;
      &lt;item name="theme"&gt;@style/ThemeOverlay.AppCompat.Dark.ActionBar&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p></p>
  
  <p>and the layout:</p>
  
  <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context=".MainActivity"&gt;
  
  &lt;android.support.v7.widget.Toolbar
      style="@style/ToolBarStyle"
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:background="@color/material_blue_grey_800"
      android:minHeight="@dimen/abc_action_bar_default_height_material"
      android:id="@+id/toolbar_actionbar"
  
      /&gt;
  
  &lt;TextView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="#478"
      android:text="@string/hello_world" /&gt;
  </code></pre>
  
  <p></p>
  
  <p>I thought that by calling setSupportActionbar the system would take care of positioning content below the toolbar view but that is not what I am seeing.</p>
  
  <p>What is the correct way of using the toolbar. I have some activities where I wan the toolbar to be transparent with the content behind it it and others where I want it to be opaque with the content below.</p>
  
  <p>Thanks</p>
