如何从选项卡式 Activity 内的片段的 Textview/Button 开始新的 activity

Question

如上图所示，我创建了一个名为CustomerFragLogin的Fragment，代码如下：-

    public class customerFragLogin extends Fragment {
    

    private static final String ARG_PARAM1 = "param1";
    private static final String ARG_PARAM2 = "param2";

    private String mParam1;
    private String mParam2;

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


    public static customerFragLogin newInstance(String param1, String param2) {
        customerFragLogin fragment = new customerFragLogin();
        Bundle args = new Bundle();
        args.putString(ARG_PARAM1, param1);
        args.putString(ARG_PARAM2, param2);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
            mParam1 = getArguments().getString(ARG_PARAM1);
            mParam2 = getArguments().getString(ARG_PARAM2);
        }

    }


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


}

现在，当我单击 'Login' 按钮或 'Forget password' 文本视图时，我想打开一个新的 activity。我该如何实施？

将此添加到您的 CustomerFragLogin

@Override
    public void onViewCreated(@NotNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        
        TextView textView= findViewById(R.id.textView)
        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                startActivity(new Intent(getActivity(), NewActivity.class));   
            }
        });
       
    }

确保您的 activity 已在清单中声明
