To make a ListView with rounded corners make a new xml file which will handle the rounded corners. “roundedlistview.xml”
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#ffffff" android:endColor="#000000"
android:angle="270"/>
<corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp" android:topRightRadius="7dp"/>
</shape>
Now to call this you can do this by code or through xml.
listView.setBackgroundResource(R.drawable.roundedlistview);
android:background="@drawable/roundedlistview"
