title: EditText & TextView textColorPrimary does not follow Theme color for API < 21
body: <p>There some issue in styling the Toolbar view to make it work for both API 21 and below but consider I have this styles.xml</p>
  
  <pre><code>&lt;!-- Base application theme. --&gt;
  &lt;style name="AppTheme" parent="AppTheme.Base"&gt;
      &lt;!-- Customized theme for API &lt; 21 --&gt;
  &lt;/style&gt;
  
  &lt;style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar"&gt;
      &lt;item name="colorPrimary"&gt;@color/colorPrimary&lt;/item&gt;
      &lt;item name="colorPrimaryDark"&gt;@color/colorPrimaryDark&lt;/item&gt;
  &lt;/style&gt;
  
  &lt;style name="AppToolbarTheme" parent="ThemeOverlay.AppCompat.Dark.ActionBar"&gt;
      &lt;item name="android:background"&gt;@color/colorPrimary&lt;/item&gt;
      &lt;item name="android:textColorPrimary"&gt;@color/white&lt;/item&gt;
      &lt;item name="android:textColorSecondary"&gt;@color/grey&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>and this in my screen1.xml Toolbar</p>
  
  <pre><code>&lt;android.support.v7.widget.Toolbar
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      app:theme="@style/AppToolbarTheme"
      app:popupTheme="@style/AppPopupToolbarTheme"
      android:id="@+id/app_bar"&gt;
  
      &lt;RelativeLayout
          android:layout_width="match_parent"
          android:layout_height="wrap_content"&gt;
          &lt;TextView
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:id="@+id/toolbar_text"
              android:textColor="?android:textColorPrimary"
              android:gravity="center"/&gt;
          &lt;!-- other views here --&gt;
      &lt;/RelativeLayout&gt;
  &lt;/android.support.v7.widget.Toolbar&gt;
  </code></pre>
  
  <p>The <code>"?android:textColorPrimary"</code> above does not work in API &lt; 21 and fall back to dark text color instead of my <code>@color/white</code>.</p>
  
  <p>However I still believe it possible since "auto-generated" TextView title by using <code>setSupportActionBar((Toolbar) findViewById(R.id.app_bar));</code> in <code>Activity.onCreate()</code>, I can see the TextView follow my <code>textColorPrimary</code>.</p>
  
  <ol>
  <li>What should be in the <code>android:textColor=</code>? or</li>
  <li>how can I see the generated TextView from ActionBar support (like browser F12)? so I can apply the same.</li>
  </ol>
