我又没钱买奔驰，我也来谈996，再说我又不是刘*东，也没法带这些996的兄弟们一起到国外去喝奶茶。不对不对，跑题了。

好，那么下面我们来进入正题。话说我如果是电商王子，我就叫小马，我全力支持996这种工作模式，别问我为什么，因为我对钱没有兴趣。

嗨，终究是沉浸于逻辑程序逻辑中无法自拔了，写个博客都要跑题半天。好吧话不多说，话说这个IPTV桌面背景图片自动播放效果，嗯，IPTV之所以有这般夕阳红的景象多得益于*电的垄断式运营模式。靠

跑题了！

ViewFlipper简单使用

xml定义

<ViewFlipperandroid:id="@+id/images"android:layout_width="match_parent"android:layout_height="match_parent" >
</ViewFlipper>

Activity怎么弄

    private int[] imgs = { R.drawable.photo1, R.drawable.photo2,R.drawable.photo3 };private ViewFlipper flipper;private int delayMillis = 5 * 1000;
@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);flipper = (ViewFlipper) findViewById(R.id.images);LayoutInflater inflater = LayoutInflater.from(this);for (int i = 0; i < imgs.length; i++) {ImageView iv=new ImageView ();iv.setScaleType(ImageView.ScaleType.FIT_XY);iv.setBackgroundResource( imgs[i]);flipper.addView(iv);}// 图片播放的时间flipper.setFlipInterval(delayMillis);// 是否允许自动播放flipper.setAutoStart(true);// 启动，开始播放if (flipper.isAutoStart() && !flipper.isFlipping()) {flipper.startFlipping();}
}

图片倒影

自动播放图片就是这么简单，不加一点动画或图片处理什么的也太对不起996大佬对我们的厚爱了，下面做一下图片倒影处理；

public static Bitmap createReflectedImage(Context context, int drawable) {Bitmap bmp = BitmapFactory.decodeResource(context.getResources(),drawable);final int reflectionGap = 1;int width = bmp.getWidth();int height = bmp.getHeight();Matrix matrix = new Matrix();matrix.preScale(1, -1);Bitmap reflectionImage = Bitmap.createBitmap(bmp, 0, height / 2, width,height / 2, matrix, false);Bitmap bitmapWithReflection = Bitmap.createBitmap(width,(height + height / 5), Config.ARGB_8888);Canvas canvas = new Canvas(bitmapWithReflection);canvas.drawBitmap(bmp, 0, 0, null);Paint defaultPaint = new Paint();canvas.drawRect(0, height, width, height + reflectionGap, defaultPaint);canvas.drawBitmap(reflectionImage, 0, height + reflectionGap, null);Paint paint = new Paint();LinearGradient shader = new LinearGradient(0, bmp.getHeight(), 0,bitmapWithReflection.getHeight() + reflectionGap, 0x70000000,0x00000000, TileMode.MIRROR);paint.setShader(shader);paint.setXfermode(new PorterDuffXfermode(Mode.DST_IN));canvas.drawRect(0, height, width, bitmapWithReflection.getHeight()+ reflectionGap, paint);return bitmapWithReflection;}

遥控器左右键切换图片

完了该滚的也滚了，该倒的也倒过来了，别误解，我说的是图片哈，下面来说一下实际应该场景吧！这玩意一般可以用于滚动广告，酒店服务介绍界面等，好吧，举一个栗子，遥控器左右键切换；

@Override
public boolean dispatchKeyEvent(KeyEvent event) {int keyCode = event.getKeyCode();final boolean uniqueDown = event.getRepeatCount() == 0&& event.getAction() == KeyEvent.ACTION_DOWN;// 上键上一页if (uniqueDown && keyCode == KeyEvent.KEYCODE_DPAD_LEFT) {flipper.showPrevious();pauseFlipping();return true;}// 按右键下一页else if (uniqueDown && keyCode == KeyEvent.KEYCODE_DPAD_RIGHT) {flipper.showNext();pauseFlipping();return true;}return super.dispatchKeyEvent(event);}/*** 暂停一会了*/
public void pauseFlipping() {flipper.stopFlipping();if (startFlippingTask != null) {startFlippingTask.cancel();startFlippingTask = null;}startFlippingTask = new TimerTask() {@Overridepublic void run() {// TODO Auto-generated method stubhandler.sendEmptyMessage(1);}};mTimer.schedule(startFlippingTask, delayMillis);
}/*** 开始播放*/
public Timer mTimer = new Timer();
public TimerTask startFlippingTask;
@SuppressLint("HandlerLeak")
Handler handler = new Handler() {public void handleMessage(android.os.Message msg) {flipper.startFlipping();};
};

来来来，总结一下，其实不用写这一推没用，只是为了好看一点罢了，当然你可以做一下手势判断，做左右滑动切换，看下面这里：

flipper.showPrevious();//上一张
flipper.showNext();//下一张
flipper.startFlipping();//开始播放
