<p>I am developing application which have multi screen support. I have completed all remain layout as per device size but I am unable to increase Actionbar/Toolbar size for same. its looking small in 10inch tablet. How can I increase size of toolbar text ?</p>

<p>My Style XML is like below </p>

<pre><code>&lt;resources&gt;

&lt;!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
--&gt;
&lt;style name="AppBaseTheme" parent="android:Theme.Light"&gt;

&lt;/style&gt;


&lt;style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"&gt;
    &lt;!-- Customize your theme here. --&gt;
    &lt;item name="colorPrimary"&gt;@color/colorPrimary&lt;/item&gt;
    &lt;item name="colorPrimaryDark"&gt;@color/colorPrimaryDark&lt;/item&gt;
    &lt;item name="colorAccent"&gt;@color/colorAccent&lt;/item&gt;
&lt;/style&gt;

&lt;style name="AppTheme.NoActionBar"&gt;
    &lt;item name="windowActionBar"&gt;false&lt;/item&gt;
    &lt;item name="windowNoTitle"&gt;true&lt;/item&gt;
&lt;/style&gt;
&lt;style name="AppTheme.FullScreen" parent="noActionBar"&gt;
&lt;item name="android:windowFullscreen"&gt;true&lt;/item&gt;
&lt;/style&gt;
&lt;style name="noActionBar" parent="Theme.AppCompat.NoActionBar"&gt;
    &lt;item name="colorPrimary"&gt;@color/colorPrimary&lt;/item&gt;
    &lt;item name="colorPrimaryDark"&gt;@color/colorPrimaryDark&lt;/item&gt;
    &lt;item name="colorAccent"&gt;@color/colorAccent&lt;/item&gt;
&lt;/style&gt;
&lt;style name="OptionDialog" parent="Theme.AppCompat.Dialog.Alert"&gt;

    &lt;item name="colorAccent"&gt;#C5CAE9&lt;/item&gt;
    &lt;item name="android:background"&gt;#3F51B5&lt;/item&gt;
    &lt;item name="android:textColor"&gt;?android:attr/textColorPrimaryInverseDisableOnly&lt;/item&gt;
&lt;/style&gt;


&lt;style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" /&gt;

&lt;style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" /&gt;

&lt;style name="SelectableItemTheme"&gt;
    &lt;item name="colorControlHighlight"&gt;#888888&lt;/item&gt;
&lt;/style&gt;

&lt;style name="SelectableItemBackground"&gt;
    &lt;item name="android:theme"&gt;@style/SelectableItemTheme&lt;/item&gt;
    &lt;item name="android:background"&gt;?attr/selectableItemBackground&lt;/item&gt;
&lt;/style&gt;


&lt;style name="HomeTabTextStyle" 
    parent="TextAppearance.Design.Tab"&gt; 
    &lt;item name="android:textSize"&gt;35sp&lt;/item&gt; 
    &lt;item name="android:textStyle"&gt;bold&lt;/item&gt; 
    &lt;/style&gt;

&lt;!-- Action Bar Style --&gt;
</code></pre>

<p></p>

<p>and my layout xml which including toolbar is like below</p>

<pre><code>&lt;android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay"&gt;

    &lt;android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="110dp"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" /&gt;

    &lt;android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        app:tabTextAppearance="@style/HomeTabTextStyle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" /&gt;


&lt;/android.support.design.widget.AppBarLayout&gt;
</code></pre>

<p>My Java Code is like below</p>

<pre><code>setContentView(R.layout.activity_home);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    setTitle("My App Name");
</code></pre>
