Custom SeekBar in Android Studio .

In this post, you will learn to create a custom seekbar in android studio. A SeekBar is an extension of ProgressBar that adds a draggable thumb. The user can touch the thumb and drag left or right to set the current progress level or use the arrow keys to do so. To create a custom seekbar need follow these steps . 

  • Create a drawable resource file in the drawable folder. Name it whatever you want. In this we will create a custom appearance for the thumb of the seekbar . 
  • Copy the following code in this drawable folder : 
custom_thumb.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@color/colorPrimary"/>
<size android:height="55dp" android:width="25dp"/>
<corners android:radius="5dp"/>
</shape>
