我知道与画廊插件，我能够使用getSelectedItemPosition（）;检索当前位置，但它似乎并不ViewPager都有。

I know with the Gallery widget I was able to use getSelectedItemPosition(); to retrieve the current position, however it doesnt seem ViewPager has that.

我知道我可以设置一个监听和检索的位置时，页面切换。但我想当前视图位置。

I know I can setup a listener and retrieve the position when the page is switched. But I want the current view position.

推荐答案

创建一个监听器，并在你的viewpager设置：

Create a listener and set it on your viewpager:

    /**
     * Get the current view position from the ViewPager by
     * extending SimpleOnPageChangeListener class and adding your method
     */
    public class DetailOnPageChangeListener extends ViewPager.SimpleOnPageChangeListener {

        private int currentPage;

        @Override
        public void onPageSelected(int position) {
            currentPage = position;
        }

        public final int getCurrentPage() {
            return currentPage;
        }
    }
