Here is what I want to do: I have this scale xml:
<?xml version="1.0" encoding="utf-8"?>
<scale xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="@drawable/mydrawable" android:scaleGravity="bottom"
android:scaleHeight="50%" />
And I want to use it with this drawable xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#FFFFFFFF"
android:endColor="#FFFF0000"
android:angle="90" />
</shape>
</item>
</layer-list>
Then I set the scale xml as a background for a LinearLayout, but I don't see anything. Am I missing something or is it not possible to do this (with XML)?

This is an issue with the ScaleDrawable object which cannot be resolved in XML.
ReplyDeleteBut it is easy, just do the following:
// Get the scale drawable from your resources
ScaleDrawable scaleDraw = (ScaleDrawable)getResources().getDrawable(R.drawable.background_scale);
// set the Level to 1 (or anything higher than 0)
scaleDraw.setLevel(1);
// Now assign the drawable where you need it
layout.setBackgroundDrawable(scaleDraw);
I tested your code using this solution and it worked fine.
