    we can set arrow based seekbar using following trick like this : First of all you have to set a image of scale then below that image set a seekbar with progressDrawable transparent and then set arrow image as a thumb.

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical" android:layout_width="match_parent"
        android:layout_height="match_parent">
       
        <TextView
            android:id="@+id/tvValue"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:gravity="center"
            android:text="0/100"
            android:textSize="22sp"
            android:textStyle="bold" />
    
    
        <FrameLayout
