设置onPageChangeListener方法即可

viewPagerl.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {@Overridepublic void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}@Overridepublic void onPageSelected(int position) {// 把当前显示的position传递出去Log.i("Lgq","ssssssslllllll=="+position);}@Overridepublic void onPageScrollStateChanged(int state) {}
});
