多个截击请求的java问题

Question

每当我想根据用户输入执行截击请求时，我必须按两次按钮来获得请求的响应，而不是只单击一次按钮

我使用了wait（）函数，但仍然存在同样的问题，应用程序已损坏，而我希望应用程序能正常工作

这就是我到目前为止所做的：

   String URL="https://apifootball.com/api/?action=get_countries&APIkey=b4c74bf2fcf3937f783b752649018a42a3b1bde9d5d7c03ff36f61fc06c00c77";
        RequestQueue rq= Volley.newRequestQueue(this);

        JsonArrayRequest objreq= new JsonArrayRequest(

                Request.Method.GET,
                URL,
                null,
                new Response.Listener<JSONArray>()
                {
                    @Override
                    public void onResponse(JSONArray response) {
                        try {

                            Log.e("result:",response.get(0).toString());
                            JSONObject obj;
                            for (int count = 0; count < response.length(); count++) {
                                obj = response.getJSONObject(count);
                                String name = obj.getString("country_name");
                                Log.e("Country:",name);
                                send(name,true);
                                //  Team t=new Team(2,"mki");
                                //x.insertTeam(t);
                                //so on
                            }

                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                },
                new Response.ErrorListener(){

                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Log.e("rest response",error.toString());
                    }
                }
        );
        rq.add(objreq);

        btn_send_message.setOnClickListener(new View.OnClickListener() {
            ChatModel model;
public void onClick(View v) {
                String text = editText.getText().toString();
else if(text.contains("result"))
                {
                    ChatModel model = new ChatModel(text, true); // user send message
                    list_chat.add(model);

                    String result="";
                    String head2Head;
                    String input[] = text.split(" ");
                    String[] arr=null ;
                    DBAdapter dbAdapter=new DBAdapter(x);
                    try{
                        result=dbAdapter.getResultfromDB("Bristol City","Reading");

                    }catch (Exception e)
                    {
                        result="error";
                    }

                    if(result.equals("error")==true) {

                        APIAdapter ap = new APIAdapter();
                        head2Head = ap.getResult("Bristol City", "Reading", "kjkn", getApplicationContext());
                        finres = head2Head;
                        Log.e("headto",head2Head);
                        arr = head2Head.split("\n");
                        }
                    model = new ChatModel("First team:"+arr[0]+"\nSecond team:"+arr[1]+"\n"+"Date:"+arr[2], false);
                    list_chat.add(model);
                }
}
