  <p>The device is Samsung Galaxy SIII
  Emulator is Nexus 5</p>
  <p>Button code :</p>
  <p>This is the XML code of the button</p>
  <pre><code>        &lt;Button
          android:id=&quot;@+id/button_main_start&quot;
  
          android:text=&quot;@string/button_Start&quot;
          android:textSize=&quot;30sp&quot;
  
          android:layout_width=&quot;270dp&quot;
          android:layout_height=&quot;60dp&quot;
  
          android:theme=&quot;@style/buttonTheme&quot;
          android:textAllCaps=&quot;false&quot;
  
          android:gravity=&quot;center_horizontal&quot; /&gt;
  
  
  &lt;style name=&quot;buttonTheme&quot; parent=&quot;android:style/Theme.NoTitleBar&quot;&gt;
      &lt;item name=&quot;android:buttonStyle&quot;&gt;@style/button&lt;/item&gt;
  &lt;/style&gt;
  
          &lt;style name=&quot;button&quot; parent=&quot;android:Widget.Button&quot;&gt;

      &lt;item name=&quot;android:shadowDx&quot;&gt;0&lt;/item&gt;
      &lt;item name=&quot;android:shadowDy&quot;&gt;-1&lt;/item&gt;
      &lt;item name=&quot;android:shadowRadius&quot;&gt;0.2&lt;/item&gt;
      &lt;item name=&quot;android:textSize&quot;&gt;16sp&lt;/item&gt;
      &lt;item name=&quot;android:textStyle&quot;&gt;bold&lt;/item&gt;
      &lt;item name=&quot;android:background&quot;&gt;@drawable/button&lt;/item&gt;
      &lt;item name=&quot;android:focusable&quot;&gt;true&lt;/item&gt;
      &lt;item name=&quot;android:clickable&quot;&gt;true&lt;/item&gt;
  
  &lt;/style&gt;
  
  &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
  
   &lt;shape xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot; android:shape=&quot;rectangle&quot;&gt;
  &lt;gradient
      android:startColor=&quot;#00CCFF&quot;
      android:centerColor=&quot;#0000CC&quot;
      android:endColor=&quot;#00CCFF&quot;
      android:angle=&quot;90&quot;/&gt;
  &lt;padding android:left=&quot;7dp&quot;
      android:top=&quot;7dp&quot;
      android:right=&quot;7dp&quot;
      android:bottom=&quot;7dp&quot; /&gt;
  &lt;stroke
      android:width=&quot;2dip&quot;
      android:color=&quot;#FFFFFF&quot; /&gt;
  &lt;corners android:radius= &quot;8.0dp&quot; /&gt;
  &lt;/shape&gt;

  <p>New to Mobile development so tell me if more information is needed.</p>
  <p>MY SOULUTION:
  Not sure if this is the proper solution but I put &quot;android:theme=&quot;@style/buttonTheme&quot; in the manifest.xml and it worked out.</p>
