Android gallery 实现定时滑动并添加动画效果

    private int currentItem = 0;
    #new一个Handler 和 Runnable
    private final Handler myHandler = new Handler();
    private final Runnable slideRunnable = new Runnable() {
        @Override
        public void run() {
            currentItem++;
            mGallery.setSelection(currentItem,false);
            #模拟动画效果
            mGallery.onKeyDown(KeyEvent.KEYCODE_DPAD_RIGHT,null);
            #设置下次滑动的定时器
            myHandler.postDelayed(this, 4000);
        }
    };
    #启动定时器
    myHandler.postDelayed(slideRunnable, 4000);

注： 关闭此定时器方法
myHandler.removeCallbacks(slideRunnable);
