今天想在一个Activity的子类里实现两个TAB左右滑动切换的效果。
于是想借助ViewPager和Fragment来搞
主要代码大概如下
mViewPager = (ViewPagerExt) findViewById(R.id.viewpager);//mViewPager是定义在当前Layout中的 mViewPager.setAdapter(new FragmentPagerAdapter(FragmentManager, List<Fragment>)); //传入的参数，第一个参数是 MainFragment.getInstance().getSupportFragmentManager()
报了如下异常，感觉很莫名其妙 No view found for id 0x7f0a0075 (com.xxx.xxx:id/viewpager) for fragment
查了半天，原来setAdapter的时候会在传入的第一个参数MainFragment所在的layout中查找该ID
于是不得不改变当前类的父类
OrderActivity extends FragmentActivity 而不是继承Activity
