Change scrollbar color in Android

You can set Listview property as

android:scrollbarSize="10dp"
android:scrollbarThumbVertical="@drawable/custom_scroll_style"

Here custom_scroll_style is a xml file under the drawable folder. Lets create the custom_scroll_style.xml.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

<gradient
    android:angle="45"
    android:endColor="#FF3401"
    android:centerColor="#ff5c33"
    android:startColor="#FF3401" />

<corners android:radius="8dp" />
<size android:width="4dp"/>
<padding
    android:left="0.5dp"
    android:right="0.5dp" />

</shape>

Here I got a Orange color scrollbar. You can use images also if the image size is less than 2px instead of xml.
