[android-developers] onscrollchanged in horizontal scroll view

Hi there,

i need to implement onscrollchanged method in my class so that when scroll is changing i will update seek bar position as per scroll value.

i implemented a customhorizontalview class with extends HorizontalScrollView.

also created customhorizontalview in xml . but my problem is that how to override onscrollchange method in my class so that as scroll is changing i could update seek bar corresponding to horizontal scroll.

here is my customhorizontalview class

import android.content.Context;

import android.util.AttributeSet;

import android.util.Log;

import android.widget.HorizontalScrollView;

public class CustomHorizontalScroll extends HorizontalScrollView  {

   

    public interface onScrollChangedListener{

        public abstract void onScrollChanged(int l, int t, int oldl, int oldt);

    }

   

    onScrollChangedListener mMyScrollViewListener; 

    public void setMyScrollViewListener(onScrollChangedListener listener ){

        mMyScrollViewListener = listener;

    }

   

    @Override

    protected void onScrollChanged(int l, int t, int oldl, int oldt) {

        super.onScrollChanged(l, t, oldl, oldt);

        Log.v("Positions",l+","+t) ;

    }

    public CustomHorizontalScroll(Context context, AttributeSet attrs) {

        super(context, attrs);

        // TODO Auto-generated constructor stub

       

    }

}

i am using this in my java file 

hs_scroll_view = (CustomHorizontalScroll) findViewById(R.id.id_hs_scroll_view) ;

i want to override onscrollchanged in my java file so that i could update seek bar as per scroll but i don't know how to do that .

please suggest me any idea ?

thanks
