我想在我的Android应用程序中使用.net Web服务.我通过使用asynctask将请求发送到Web服务.但是请求的价值不正确.我在许多androID应用程序中使用了这种结构,但从未遇到这样的错误.问题是什么？

我有权限(互联网).命名空间和方法名称为true.

编辑：我编辑了代码,但不使用对话框.请不要写关于对话框的答案.对话框不会出现问题.

解决方法:

您将需要在onPreExecute而不是在类级别初始化ProgressDialog：

private ProgressDialog dialog;  //declare here    @OverrIDe     protected voID onPreExecute() {        dialog = new ProgressDialog(MainActivity.this); //<< initialize here        dialog.setMessage("Loading...");        dialog.show();     } //.....protected voID onPostExecute(String[][] items){    ASFinish();    if(null !=dialog)     if(dialog.isShowing())       dialog.dismiss();}
