How to increase hit area of Android button without scaling background?
<p>I have a button with a custom drawable.</p>

<pre><code>&lt;Button
    android:layout_width="22dip"
    android:layout_height="23dip"
    android:background="@drawable/triangle" /&gt;
</code></pre>

<p>The drawable is a triangle with transparent background. </p>

<pre><code>|\
| \
|__\
</code></pre>

<p>I find this button hard to tap. First, it's relatively small. Second, the transparent pixels are not tappable. I would like to keep the drawable the same size, but make the hit area a square shape twice the size of the triangle.</p>

<pre><code>_____________
|            |
|    |\      |
|    | \     |
|    |__\    |
|____________|
</code></pre>
