我正在尝试通过检查我的片段中的文档来运行个性洞察力

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final View x = inflater.inflate(R.layout.fragment_analyzer, container, false);
        PersonalityInsights service = new PersonalityInsights();
        service.setUsernameAndPassword("", "");
        service.setEndPoint("https://gateway.watsonplatform.net/personality-insights/api");
        EditText content=  x.findViewById(R.id.content);
        TextView output=  x.findViewById(R.id.output);
//        String text = content.getText().toString();
        String text =getResources().getString(R.string.demo);
        Profile profile = service.getProfile(text);
        System.out.println(profile);
        return x;
    }

为此，我插入了我的 gradle 文件

compile 'com.squareup.okhttp3:okhttp:3.10.0'
    compile 'com.google.code.gson:gson:2.8.2'
    compile 'com.ibm.watson.developer_cloud:java-sdk:2.10.0'

有没有人遇到过这个错误？可以证明我做错了什么吗？提前谢谢你！

new Thread(new Runnable(){Profile profile = service.getProfile(text);
}).start();

或者使用异步任务。您只能在onCreateView. 所有其他对象初始化必须在您的onActivityCreated

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onActivityCreated(savedInstanceState);
      final  String text =getResources().getString(R.string.demo);

            new AsyncTask<Void, Void, Void>() {
                @Override
                protected Profile doInBackground(Void... params) {

        PersonalityInsights service = new PersonalityInsights();
                            service.setUsernameAndPassword("", "");
        service.setEndPoint("https://gateway.watsonplatform.net/personality-insights/api");

        Profile profile = service.getProfile(text);
       return profile;
               }

                @Override
                protected void onPostExecute(Profile profile) {
                    super.onPostExecute(profile);

        TextView output =  x.findViewById(R.id.output);
                 output.setText(profile.toString())
           }
              }.execute();

}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final View x = inflater.inflate(R.layout.fragment_analyzer, container, false);
        EditText content=  x.findViewById(R.id.content);
        TextView output =  x.findViewById(R.id.output);
//        String text = content.getText().toString();
        return x;
    }
