如何从 Android 中的片段启动浏览器 activity

Question

我想从我的片段打开浏览器但是当我启动我的应用程序时它崩溃了怎么了？

public class C_spider extends Fragment {

Button btn_off2;

public C_spider() {
    // Required empty public constructor
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view=  inflater.inflate(R.layout.fragment_cspider, container, false);

    btn_off2 = (Button)view.findViewById(R.id.btn_off2);
    btn_off2.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent i = new Intent(Intent.ACTION_VIEW);
            i.setData(Uri.parse("https://www.google.com"));
            getActivity().startActivity(i);

        }
    });

    return view;
}

}

尝试将您的代码放入 onActivityCreated()

public class C_spider extends Fragment {

    Button btn_off2;

    public C_spider() {
     // Required empty public constructor
    }

    @Override
         public View onCreateView(LayoutInflater inflater, ViewGroup container,
         Bundle savedInstanceState) {
         // Inflate the layout for this fragment
         View view=  inflater.inflate(R.layout.fragment_cspider, container,   false);  
        return view;
    }



    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        btn_off2 = (Button)getActivity().findViewById(R.id.btn_off2);
        btn_off2.setOnClickListener(new View.OnClickListener() {
       @Override
        public void onClick(View v) {
            Intent i = new Intent(Intent.ACTION_VIEW);
            i.setData(Uri.parse("https://www.google.com"));
            getActivity().startActivity(i);

            }
        });

    }

 }
