android - ViewPager ループ?

Question

ViewPager の実装を、最後のビューで停止するのではなく、ビュー間を循環させたいと考えています。たとえば、ViewPager を介して表示する 3 つのビューがある場合、3 番目のビューで停止するのではなく、フリングで 3 番目のビューの後に最初のビューに戻る必要があります。ユーザーが最後のページで前方に飛んだときに、最初のページ/ビューに戻りたい

どうもありがとう、

mViewPager.setOnPageChangeListener(new OnPageChangeListener() {
    @Override
    public void onPageSelected(int arg0) {

    }
    @Override
    public void onPageScrolled(int arg0, float arg1, int arg2) {
        if(arg0 == 0 && (arg1 <= 0.001f && arg1 >= -0.001f)){
            mVp.setCurrentItem(list.size()-2, false);
        }else if(arg0 == list.size() - 1){

        }
    }
