How keep aspect ratio in bitmap drawable
<p>How I can keep aspect ratio if I am using gravity <code>fill_vertical</code> or <code>fill_horizontal</code>? In this code:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;bitmap xmlns:android="http://schemas.android.com/apk/res/android" 
    android:src="@drawable/_toogle_green"
    android:gravity="bottom|fill_vertical"
/&gt;
</code></pre>

<p>bitmap fills vertical, but in horizontal keeps original width and aspect ratio is broken.</p>

<p>I believe this question was asked, but I really can't find it, only for ImageView or ImageButton. But I need do that in drawables.</p>
