ViewFlipper类和WindowManager类
animation动画效果translate和alpha
设置布局文件，其内容如下：activity_image_flipper_shade.xml
动画效果配置文件，其内容如下：A.push_left_in.xml（从左边进入屏幕）
实现图片轮播切换的类为ImageFlipperShadeActivity.java，其内容为：/** * */package com.i114gbox.aglieguy;import android.annotation.SuppressLint;import android.content.Context;import android.graphics.PixelFormat;import android.os.Bundle;import android.os.Handler;import android.view.Gravity;import android.view.MotionEvent;import android.view.View;import android.view.View.OnClickListener;import android.view.WindowManager;import android.view.WindowManager.LayoutParams;import android.view.animation.AnimationUtils;import android.widget.Button;import android.widget.ImageView;import android.widget.ViewFlipper;import com.i114gbox.sdk.activity.I114gBoxActivity;import com.i114gbox.sdk.utils.I114gBoxCollectActivityUtils;import com.i114gbox.sdk.utils.I114gBoxLogUtils;import com.i114gbox.sdk.utils.I114gBoxResourceUtils;/** * 图片滑动渐变Activity * * @author SJC * */public class ImageFlipperShadeActivity extends I114gBoxActivity { private static String TAG = 'ImageFlipperShadeActivity';

需要设置WindowManager的属性，包含type、format和flags等等
创建左右边图片动画加载效果，并实现onTouchEvent事件，其中MotionEvent.ACTION_DOWN为按下监听事件，MotionEvent.ACTION_UP为按下后松开事件
