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, intoldt);
}
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
