我正在开发一个连接到Web服务并在列表视图中显示数据的应用程序。我可以成功显示数据[我使用了自定义列表视图并显示我使用自定义适配器类的数据由基础适配器扩展]。现在我正在尝试连接到另一个Web服务时，单击一个接受按钮[在列表视图中]。我已经开发了从服务中获取字符串响应的方法，并且这些方法运行良好。[我已经通过我的应用程序进行了测试]。
我的问题是，我希望在连接到服务时显示一些进度对话框，并使用Toast消息显示响应。我已经使用AsyncTask类了。首先，我刚刚运行一个线程让它睡了一段时间。这与我的AsyncTask完全一致。但是当我在[{1}}]内使用它来调用Web服务时，我收到了一个错误：
活动com.jsonlist.jsonlist.ViewList已泄露窗口 com.android.internal.policy.impl.PhoneWindow$DecorView@41814e38那个 最初在这里添加了android.view.WindowLeaked：Activity com.jsonlist.jsonlist.ViewList已泄露窗口 com.android.internal.policy.impl.PhoneWindow$DecorView@41814e38那个 最初是在这里添加的 android.view.ViewRootImpl。（ViewRootImpl.java:374）at android.view.WindowManagerImpl.addView（WindowManagerImpl.java:292）
我的代码如下：
此方法位于我的Adapter类
中doInBackground()当我按下对话框中的“是”按钮时。它应该调用我的 public void dialogshow(final String Date,final String Start,final String End){
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(activity);
alertDialogBuilder.setTitle("Confirm your Action!");
// set dialog message
alertDialogBuilder
.setMessage("Click yes Confirm!!")
.setCancelable(false)
.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
//Toast.makeText(mContext, "Yes clicked", Toast.LENGTH_LONG).show();
new ShowResponceForAccept().execute();
}
})
.setNegativeButton("No",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
// if this button is clicked, just close
// the dialog box and do nothing
dialog.cancel();
}
});
alertDialogBuilder.show();
}
。
这是我的AsyncTask
AsyncTask这也在同一个适配器类中。
有人可以帮我吗？？
修改
这是我的完整适配器类

答案 0 :(得分：0)
调用AsyncTask后添加dialog.dismiss()
new ShowResponceForAccept().execute();
dialog.dismiss();
答案 1 :(得分：0)
在
中使用YourActivity.this代替activity
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(activity);
和
pDialog = ProgressDialog.show(activity, "Sending Request", "getting Responce.", true, false);
希望这有帮助。
