推荐答案

你可以像这样在片段中设置SupportActionbar:

You can setSupportActionbar like this in fragments:

((AppCompatActivity)getActivity()).setSupportActionBar(mToolbar);

您需要在 Fragment 的 onCreateView 中对 tabbar_layout 进行膨胀.像这样:

You need to inflate tabbar_layout in onCreateView of Fragment. Like this:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tabbar_layout, container, false);
 //YOUR STUFF
return rootView;
}
