I have a shape in circle.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval"
    >
    <solid android:color="@color/colorAccent" />
    <size
        android:width="200dp"
        android:height="200dp" />
    <corners android:radius="100dp" />
</shape>
How do i refer it from java and change its color ?
