添加setOnPageChangeListener后程序進不去了
viewPager.setOnPageChangeListener(?new?ViewPager.OnPageChangeListener()?{
????@Override
????public?void?onPageScrolled(int?index,?float?v,?int?i1)?{
????????for?(int?i?=?0;?i?<?fragments.size();?i++)?{
????????????llindicator.getChildAt(?i?).setBackgroundResource(?index==i?R.drawable.dot_focus:R.drawable.dot_normal?);
????????}
??}

這個程序有些小問題，不是這樣for的
