使用过蘑菇街的用户基本上都知道有一个加入购物车的动画效果，此处不具体描述想知道的可以去下载体验一下。
1、思路
目前想到两种方式实现这种效果，一是使用Tween动画，直截了当的进行一个移动，蘑菇街就是使用这样的方法。二是使用WindowManager创建一个View，然后对这个View进行移动。
2、实现
本文先用方式一方法实现，之后会用方式二方法实现。
方式一：
Activity代码：
- package com.kince.mogujie;
- import android.app.Activity;
- import android.content.Context;
- import android.graphics.drawable.ColorDrawable;
- import android.os.Bundle;
- import android.os.Handler;
- import android.view.Gravity;
- import android.view.LayoutInflater;
- import android.view.View;
- import android.view.View.OnClickListener;
- import android.view.animation.Animation;
- import android.view.animation.Animation.AnimationListener;
- import android.view.animation.AnimationUtils;
- import android.widget.ImageView;
- import android.widget.PopupWindow;
- import android.widget.RelativeLayout.LayoutParams;
- import android.widget.TextView;
- /**

- * @issue 1、第一次执行动画效果图片放大效果明显，之后放大效果不明显，蘑菇街也有这样的问题。
- * 2、弹出的popubWindow变形 希望对这方面了解的朋友告知一下
