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);
   }
