开发人员希望一切都很好，我陷入了从onclick方法命中api的url的问题。我想发送头中的jwt令牌和点击布局时的id值。api接受头和id参数。我无法做到这一点，因为我是一个非常新的编程世界任何帮助你的人必须非常感谢：下面是我的功能代码：

profile.setOnClickListener(new View.OnClickListener(){
            public void onClick(View v){
                String str = taginput.getText().toString();
                tag_id = taginput.getText().toString();
                    session = new SessionManager(getApplicationContext());
          //I want to send these two things to the next activity JWT to haders and id to hit api   
                    token = session.getStringData("jwtToken");
                    id = session.getStringData("mtagid");
                if(!str.isEmpty()) {

                    session = new SessionManager(getApplicationContext());
                    token = session.getStringData("jwtToken");
                    tag_id = session.getStringData("tagid");

                    Intent intent = new Intent(getApplicationContext(), CInfo.class);
                    startActivity(intent);
                }
                else {
                    Toast.makeText(getApplicationContext(),
                            "Please Enter CNIC first!", Toast.LENGTH_LONG)
                            .show();
                }

            }
        });

下面给出了编写api调用和所有功能的类：

public class CInfo extends AppCompatActivity {
    private String TAG = CInfo.class.getSimpleName();
    private ProgressDialog pDialog;
    private static final int MY_SOCKET_TIMEOUT_MS = 50000;
    ListView listView;
    List<ConstantClass> constantClassList;

    ProgressBar progressBar;
    private RequestQueue mRequestQueue;
    private SessionManager session;
    String token;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_c_info);
        Bundle extras = getIntent().getExtras();
        listView=(ListView)findViewById(R.id.listView);
        progressBar=(ProgressBar)findViewById(R.id.progress);
        pDialog = new ProgressDialog(this);
        pDialog.setCancelable(false);
        constantClassList=new ArrayList<>();

        sendAndRequestResponse();

        session = new SessionManager(getApplicationContext());
        token = session.getStringData("jwtToken");

    }

    private void sendAndRequestResponse() {

        mRequestQueue= Volley.newRequestQueue(this);

        JsonObjectRequest jsonObjectRequest = new JsonObjectRequest ( Request.Method.POST, AppConfig.URL_CARS_INFO+DemoClass.tag_id, null, new Response.Listener<JSONObject> () {

                    for (int i = 0; i < jsonArray.length (); i++) {
                        JSONObject jsonObject = jsonArray.getJSONObject ( i );

                        String ownername = jsonObject.getString ( "ownername" );

                        String tokenno = jsonObject.getString ( "tokenno" );
                        String registration = jsonObject.getString ( "registration" );
                        String cnic = jsonObject.getString("cnic");

                    }
                }

            }

        }

        )
        {
