Default AppCompatButton not writing in all caps <p>I have the support library added as a dependency</p> <p><code>compile 'com.android.support:appcompat-v7:24.2.1'</code></p> <p>My styles.xml looks like this:</p> <pre><code>&lt;resources xmlns:android="http://schemas.android.com/tools"&gt; &lt;!-- Base application theme. --&gt; &lt;style name="AppTheme" parent="Theme.AppCompat"&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;/resources&gt; </code></pre> <p>and my buttons themselves:</p> <pre><code>&lt;android.support.v7.widget.AppCompatButton android:layout_width="88dp" android:layout_height="48dp" android:layout_marginBottom="16dp" android:layout_marginEnd="16dp" android:layout_marginStart="75dp" android:layout_marginTop="82dp" android:text="RETURN" android:textSize="14sp"/&gt; </code></pre> <p>The button currently looks like this: <a href="https://i.stack.imgur.com/slL12.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/slL12.png" alt="enter image description here"></a></p> <p>Also note how I have set the text to all caps but it's getting overwritten with normal lettering. Is the style being overridden somewhere?</p> <p>I have tried adding: </p> <p><code>style="@style/Widget.AppCompat.Button"</code> to the button but nothing has happened. Where am I going wrong?</p>
