我有解决方案，而不是使用onViewCreated（）方法代替onActivityCreated（）方法，而是使用了构建版本目标API 23，谢谢。
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
insertNestedFragment();
}
// Embeds the child fragment dynamically
private void insertNestedFragment() {
FragmentManager fm = getChildFragmentManager();
mSupportMapFragment = (SupportMapFragment) fm.findFragmentById(R.id.child_fragment_container);
if (mSupportMapFragment == null) {
mSupportMapFragment = SupportMapFragment.newInstance();
fm.beginTransaction().replace(R.id.child_fragment_container, mSupportMapFragment).commit();
}
}
