I was looking for opportunities to define different shapes inside the same shape.xml and refer to each of them on some specific events.
I finally found a solution to my question. And the answer is to use a list-level.
<?xml version="1.0" encoding="utf-8"?> <level-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:maxLevel="0"> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <gradient android:startColor="#aaa" android:endColor="#eee" android:angle="270" /> <corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp" android:topLeftRadius="7dp" android:topRightRadius="7dp" /> </shape> </item> <item android:maxLevel="1"> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval"> <gradient android:startColor="#eee" android:centerColor="#ddd" android:endColor="#00fff2" android:angle="270" /> <corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp" android:topLeftRadius="7dp" android:topRightRadius="7dp" /> </shape> </item> </level-list>
Apply this to the background attribute in the style. Change between different forms can be achieved by setting the level on this element.
For example: findViewById(R.id.mybutton).getBackground().setLevel(1);
In the above code, I set the second shape to the button with id mybutton.
