<p><a href="https://i.stack.imgur.com/nP4Ev.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/nP4Ev.jpg" alt="enter image description here"></a></p>

<p>I want change colour for positive button in <code>Alertdialog</code>, and here is what i'm doing below:</p>

<p>// <code>style.xml</code></p>

<pre><code>&lt;style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert"&gt;
    &lt;item name="android:buttonBarPositiveButtonStyle"&gt;@style/positive&lt;/item&gt;
&lt;/style&gt;

&lt;style name="positive"&gt;
    &lt;item name="android:textColor"&gt;@color/accent&lt;/item&gt;
&lt;/style&gt;
</code></pre>

<p>I use the style by:</p>

<pre><code>AlertDialog.Builder builder = new AlertDialog.Builder(getActivity(), R.style.AlertDialogCustom);
</code></pre>

<p>But what i'm doing is not working, i just want to change positive button colour. I don't want change the button's colour in java code.</p>

<p>Thanks in advance :-)</p>
