获取随机ID

Question

我的方法showTrajects我循环我id的所有trajects，直到这里好。

编辑： 我一直在寻找并且问题总是得到AllPendingTrajects的最后一个ID，但为什么它没有进入第一个或第二个？ 问题出在AllPendingTrajects()：

中

public void showTrajects() {
        for (indexTrajecte = 0; indexTrajecte < contador; indexTrajecte++) {
            AllPendingTrajects();
        }
    }

 public void AllPendingTrajects(){

    AsyncHttpClient client = new AsyncHttpClient();
    String URL = "http://url.net/api/link1/"+IDTrajecte[indexTrajecte];
    client.get(URL,new AsyncHttpResponseHandler() {

        @Override
        public void onStart() {}

        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {

            JSONObject trajectes = new JSONObject();

            String strResponseBody = new String(responseBody);

            try {
                trajectes = new JSONObject(strResponseBody);
            }catch (JSONException e){
                Toast.makeText(PendingTrajectRecyclerView.this, "Error", Toast.LENGTH_SHORT).show();
            }

            try {
                JSONArray realitzas = trajectes.getJSONArray("realitzas");

                dniTaxista = trajectes.getString("taxistes_dni");
                idTraject = Integer.parseInt(trajectes.getString("ID"));

                if(DadesTaxista.DNI.equals(dniTaxista)){
                    showPendingTraject();
                }
                else {
                    SeeAllTrajects();
                }
            }catch (JSONException e){
                e.printStackTrace();
            }

        }

        @Override
        public void onFailure(int statusCode, cz.msebera.android.httpclient.Header[] headers, byte[] responseBody, Throwable error) {
            Log.d("ERROR",""+statusCode);
        }

    });
}

当我在日志中输入方法SeeAllTrajects()时，我总是得到一个随机ID 而我不知道可能是什么，这是没有意义的，我试过了创建一个全局变量但没有成功

  public void SeeAllTrajects(){
    AsyncHttpClient client = new AsyncHttpClient();
    String URL = "http://url.net/api/link2";
    client.get(URL,new AsyncHttpResponseHandler() {

        @Override
        public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {

            JSONArray trajectesJSON = new JSONArray();

            String strResponseBody = new String(responseBody);

            try {
                trajectesJSON = new JSONArray(strResponseBody);
            }catch (JSONException e){
                Toast.makeText(PendingTrajectRecyclerView.this, "Error", Toast.LENGTH_SHORT).show();
            }
            try {
                Log.d("ID TRAJECT:","d"+idByTraject);

                    }
                }catch (JSONException e){
                    e.printStackTrace();
                }
        }

        @Override
        public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
            Log.d("ERROR",""+statusCode);
        }
    });
}
