Inset drawable not working as described in documentation

Question

As described on Android Developer site:

A drawable defined in XML that insets another drawable by a specified distance. This is useful when a View

Answer 1

Another option: if you want to use DP instead of PX, try my suggestion below. From my experience, InsetDrawable only works with pixels, which I find... unhelpful. To be honest, I am not happy with this solution, but hey, it works.

<?xml version="1.0" encoding="utf-8"?>
<layer-list
    xmlns:android="http://schemas.android.com/apk/res/android">

<item
        android:bottom="10dp"
        android:drawable="@drawable/image_placeholder"
        android:top="10dp" />
</layer-list>

Answer 2

By default, setting a background drawable also applies that drawable's padding to the view. Set the padding explicitly if you don't want it to match the background drawable.

Answer 3

Try to use shape with left-padding instead of inset:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <solid android:color="@android:color/darker_gray"/>
    <padding android:left="100dp"/>
</shape>
