效果图省略。。

。

activity_main.xml（仅仅有一个自己定义ListView）

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.dampingdemo.MainActivity" >

    <com.example.dampingdemo.DampingListView1
        android:id="@+id/listView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >
    </com.example.dampingdemo.DampingListView1>

</RelativeLayout>

MainActivity(ArrayListAdapter 为了简化代码)

package com.example.dampingdemo;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;


public class MainActivity extends Activity {

	private DampingListView1 dampingListView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        dampingListView = (DampingListView1) findViewById(R.id.listView);
        
        //data
        String[] data = http://www.mamicode.com/{"A","B","C","A","B","C","A","B","C","A","B","C","A","B","C","A","B","C","A","B","C","A","B","C"};  
        //获取适配器  
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,data );  
        //设置适配器  
        dampingListView.setAdapter(adapter);  
    }
}

DampingListView1（第一种方法）

package com.example.dampingdemo;

import android.content.Context;
import android.util.AttributeSet;
import android.util.DisplayMetrics;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.ExpandableListView;
import android.widget.ListView;
/**
 *   1. 在View中添加了overSrollBy方法,用于记录x, y 轴上滚动

     2. 在AbsListView的onTouchEvent中推断是否到达边界(顶部 或 底部) ,然后调用view.overScrollBy ,传入 mScrollY等參数

     3. overScrollBy 终于赋值给View的mScrollX, mScrollY 两个变量

     4. 在AbsListView中调用完overScrollBy之后,调用invalidate重绘
 *
 */
public class DampingListView1 extends ListView {
	private static final int MAX_Y_OVERSCROLL_DISTANCE = 200;

	private Context mContext;
	private int mMaxYOverscrollDistance;

	public DampingListView1(Context context) {
		super(context);
		mContext = context;
		initBounceListView();
	}

	public DampingListView1(Context context, AttributeSet attrs) {
