类要实现implements ViewPager.OnPageChangeListener
// rudiobutton小点点和轮播图做关联，这是viewPager的监听
@Override
public void onPageSelected(int position) {
Log.e("wy", "position: " + position + " mBannerCount:" + mBannerCount);

Log.e("wy", "onPageSelected: " + realPos);
RadioButton childAt = (RadioButton) mRgHomeFragBanner.getChildAt(realPos);
childAt.setChecked(true);
}
}
