import android.content.Context;

import android.util.AttributeSet;

import android.view.MotionEvent;

import android.widget.ScrollView;

/**

public class NoScrollView extends ScrollView {

public NoScrollView(Context context) {

super(context);

}

public NoScrollView(Context context, AttributeSet attrs) {

super(context, attrs);

}

public NoScrollView(Context context, AttributeSet attrs, int defStyleAttr) {

super(context, attrs, defStyleAttr);

}

@Override

public boolean onTouchEvent(MotionEvent ev) {

return true;

}

}
