Android ViewPager自动播放

在开发Android应用的过程中，ViewPager有时候需要自动播放的功能，今天就介绍一下自动播放功能的实现，直接上代码：

 // viewpager auto play
     private static final long ANIM_VIEWPAGER_DELAY = 3000;

     private Handler h = new Handler();
     private Runnable animateViewPager = new Runnable() {
         public void run() {
             if (mViewList.size() > 0) {
                 mViewPager.setCurrentItem((mViewPager.getCurrentItem() + 1)
                         % mViewList.size(), true);
                 h.postDelayed(animateViewPager, ANIM_VIEWPAGER_DELAY);
             }
         }
     };

     @Override
     public void onPause() {
         super.onPause();
         if (h != null) {
             h.removeCallbacks(animateViewPager);
         }
     }

     @Override
     public boolean dispatchTouchEvent(MotionEvent ev) {
         if (ev.getAction() == MotionEvent.ACTION_DOWN) {
             if (h != null) {
                 h.removeCallbacks(animateViewPager);
             }
         }
         if (ev.getAction() == MotionEvent.ACTION_UP) {
             h.postDelayed(animateViewPager, ANIM_VIEWPAGER_DELAY);
         }
         return super.dispatchTouchEvent(ev);
     }

     @Override
     protected void onResume() {
         super.onResume();
         h.postDelayed(animateViewPager, ANIM_VIEWPAGER_DELAY);
    }
