SUN 今天用TabLayout的时候发现，TabLayout的setOnPageChangeListener的方法过期了，良好的编程习惯是不在项目中使用过时的方法的，所以要找一个替代的方案：
addOnPageChangeListener
- setOnPageChangeListener
mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
- addOnPageChangeListener
mViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
selectedTab(position);
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
