无法从导航抽屉中的fragment/FragmentActivity中打开FragmentActivity

Question

我有一个问题，我不能解决我的应用程序的导航抽屉。导航抽屉中的一个链接是打开一个FragmentActivity（其中包含一个ViewPager）。其他链接是片段。现在，我已经将它设置为启动该活动的意图，但我的一个片段Mapspage出现了错误。和嵌套碎片有关。我会把logcat贴在下面。现在我的NavigationDrawer onClick已经设置好：

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {

            Fragment newFragment = new MapsPage();
            FragmentManager fm = getSupportFragmentManager();
            switch(i) {
            case 0:
                newFragment = new FragOne();
                fm.popBackStack();
                break;
            case 1:
                newFragment = new FragTwo();
                fm.popBackStack();
                break;
            case 2:
                newFragment = new FragThree();
                fm.popBackStack();
                break;
            case 3:
                Intent in = new Intent(getApplicationContext(), FragmentPagerActivity.class);
                startActivity(in);
                fm.popBackStack();
                break;
            }
            fm.beginTransaction().add(R.id.main, newFragment).addToBackStack("fragback").commit();
            drawerLayout.closeDrawer(rl);
}

我的问题是“案例3：”。MapsPage是我的应用程序的核心，它在XML中有一个map片段，这在调用它时导致了一个异常。下面是一个例外：

这是关键错误：

Answer 1

你在打电话

fm.beginTransaction().add(R.id.main,newFragment).addToBackStack("fragback").commit();

在调用startactivity()之后
