How to programmatically round corners and set random background colors

by

Instead of setBackgroundColor, retrieve the background drawable and set its color:

v.setBackgroundResource(R.drawable.tags_rounded_corners);

GradientDrawable drawable = (GradientDrawable) v.getBackground();
if (i % 2 == 0) {
  drawable.setColor(Color.RED);
} else {
  drawable.setColor(Color.BLUE);
}

Also, you can define the padding within your tags_rounded_corners.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
  <corners android:radius="4dp" />
  <padding
    android:top="2dp"
    android:left="2dp"
    android:bottom="2dp"
    android:right="2dp" />
</shape>
