调用使用异步任务的android web服务? [英] Calling web service using Async task in android?
问题描述
我在哪,我传递这是需要提出请求并得到响应数据的响应方法,URL和数组列表我单独的Web服务类。我喜欢这个我登录活动调用这个Web服务
I have my separate web service class in which i just pass response method, url and array list of data which is required for making the request and getting the response. I call this web service in my login activity like this
JifWebService webServices = new JifWebService();
webServices.Execute(RequestMethod.POST,
Jifconstant.LOGIN_URL, null, logindata);
loginResponse = webServices.getResponse();
loginResponseCode = webServices.getResponseCode();
在此登录数据是包含一些数据的数组列表。现在,我想用异步任务调用后台此Web服务。但我只是没有得到它正确。我的Web服务的逻辑是用完全不同的Java文件和它工作正常,但我想打电话给我的内部异步任务的Web服务方法。在此输入code
In this login data is a array list which contains some data. Now i want to call this web service in background using async task. But i am just not getting it correctly. My web service logic is written in totally different java file and its working fine but i want to call my web service methods inside async task.enter code here
推荐答案
您可以试试下面$ C $下异步任务和还调用Web服务的 doInBackground
You can try below code for Async Task and also call web service in doInBackground:
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
public class AsyncExample extends Activity{
private String url="http://www.google.co.in";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new AsyncCaller().execute();
}
private class AsyncCaller extends AsyncTask<Void, Void, Void>
{
ProgressDialog pdLoading = new ProgressDialog(AsyncExample.this);
@Override
protected void onPreExecute() {
super.onPreExecute();
//this method will be running on UI thread
pdLoading.setMessage("Loading...");
pdLoading.show();
}
@Override
protected Void doInBackground(Void... params) {
//this method will be running on background thread so don't update UI frome here
//do your long running http tasks here,you dont want to pass argument and u can access the parent class' variable url over here
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
//this method will be running on UI thread
pdLoading.dismiss();
}
}
}
完成
