Android中监听ScrollView滑动停止和滑动到底部

1.监听ScrollView滑动停止:

/********************监听ScrollView滑动停止*****************************/
scrollView.setOnTouchListener(new OnTouchListener() {
    private int lastY = 0;
    private int touchEventId = -9983761;
    Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            View scroller = (View) msg.obj;
            if (msg.what == touchEventId) {
                if (lastY == scroller.getScrollY()) {
                    handleStop(scroller);
                } else {
                    handler.sendMessageDelayed(handler.obtainMessage(touchEventId, scroller), 5);
                    lastY = scroller.getScrollY();
                }
            }
        }
    };


    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            handler.sendMessageDelayed(handler.obtainMessage(touchEventId, v), 5);
        }
        return false;
    }


    private void handleStop(Object view) {
        ScrollView scroller = (ScrollView) view;
        scrollY = scroller.getScrollY();
    }
});
/***********************************************************/

2.监听ScrollView滑动到底部:

package com.example.webviewdemo;

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ScrollView;

public class ScrollBottomScrollView extends ScrollView {

    private ScrollBottomListener scrollBottomListener;

    public ScrollBottomScrollView(Context context) {
        super(context);
    }

    public ScrollBottomScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public ScrollBottomScrollView(Context context, AttributeSet attrs,int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onScrollChanged(int l, int t, int oldl, int oldt){
        if(t + getHeight() >=  computeVerticalScrollRange()){
            //ScrollView滑动到底部了
            scrollBottomListener.scrollBottom();
        }
    }

    public void setScrollBottomListener(ScrollBottomListener scrollBottomListener){
        this.scrollBottomListener = scrollBottomListener;
    }

    public interface ScrollBottomListener{
        public void scrollBottom();
    }

}
