在Android中不停地自动滚动viewpager [英] Non stop auto scroll of viewpager in android

问题描述

我已经使用计时器自动滑动Viewpager.但是到达最后一页后计时器停止.如何使其从首页再次继续?

I have used timer to auto swipe the viewpager. But after reaching the last page the timer stops. How to make it to continue again from the first page?

final Handler mHandler = new Handler();
    final Runnable mUpdateResults = new Runnable() {
        public void run() {
            pager.setCurrentItem(page++);

        }
    };

    int delay = 1000; // delay for 1 sec.

    int period = 4000; // repeat every 4 sec.

    Timer timer = new Timer();

    timer.scheduleAtFixedRate(new TimerTask() {

    public void run() {

         mHandler.post(mUpdateResults);

    }

    }, delay, period);

推荐答案

final Runnable mUpdateResults = new Runnable() {
    public void run() {
        int numPages = pager.getAdapter().getCount();
        page = (page + 1) % numPages;
        pager.setCurrentItem(page);

    }
};

当当前项目超过寻呼机限制时，会将当前项目设置为0

That will set the current item to 0 when it exceeds the pager limits
