title: Toolbar overlapping below status bar
body: <p>I want to have appcompat v21 toolbar in my activity. But the toolbar I'm implementing is overlapping below status bar. How can I fix it?</p>

  <p>Here is the activity layout xml:</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:orientation="vertical"&gt;
  
      &lt;include
          android:id="@+id/toolbar"
          layout="@layout/toolbar" /&gt;
  
      &lt;FrameLayout
          android:id="@+id/container"
          android:layout_width="fill_parent"
          android:layout_height="0dp"
          android:layout_weight="1" /&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>Toolbar view:</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_height="wrap_content"
      android:minHeight="?attr/actionBarSize"
      android:background="?attr/colorPrimary" /&gt;
  </code></pre>
  
  <p>Theme style:</p>
  
  <pre><code>&lt;style name="AppTheme" parent="MaterialNavigationDrawerTheme.Light.DarkActionBar"&gt;
      &lt;item name="colorPrimary"&gt;@color/primary&lt;/item&gt;
      &lt;item name="colorPrimaryDark"&gt;@color/primary_dark&lt;/item&gt;
      &lt;item name="colorAccent"&gt;@color/accent&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
