Android高仿QQ消息滑动删除(附源码)

大家都应该使用过QQ吧,他的消息中可以滑动删除功能,我觉得比较有意思,所以模仿写了一个,并且修改了其滑动算法.我先贴几个简单示范图吧

其实主要用的是算法以及对ListView的把控.

一下是适配器的类

package com.fay.adapter;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

import android.app.Activity;
import android.content.Context;
import android.graphics.Point;

}

　多余的我不说了,你们直接看源码吧.
