Use the below code in your rounded_edittext.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#FFFFFF" />
<stroke
android:width="1dp"
android:color="#2f6699" />
<corners
android:radius="10dp"
/>
</shape>
This should work
