我正在開發一個應用程序，它正在連接到一個web服務並在列表視圖中顯示數據。我可以成功顯示數據[我已經使用自定義列表視圖並顯示我使用自定義數據由Base Adapter擴展的適配器類]。現在我正在嘗試連接到另一個Web服務，當一個接受按鈕被點擊時[在列表視圖中]。我開發了從服務獲得字符串響應的方法，這些方法運行良好[我已通過我的應用測試過]。異步任務錯誤Android
我的問題是，我想在連接到服務時顯示一些進度對話框，並使用Toast消息顯示響應。我已經使用AsyncTask類。首先，我剛剛運行一個線程並讓它睡了一段時間。這與我的AsyncTask完美配合。但是，當我打電話[中doInBackground()]使用它的網絡服務，我得到了一個錯誤：
Activity com.jsonlist.jsonlist.ViewList has leaked window [email protected] that was originally added here android.view.WindowLeaked: Activity com.jsonlist.jsonlist.ViewList has leaked window [email protected] that was originally added here at android.view.ViewRootImpl.(ViewRootImpl.java:374) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:292)
我的代碼如下：
這個方法是我的適配器類的內部
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();
}
時我從對話框中按下「是」按鈕。它應該打電話給我的AsyncTask。
這裏是我的AsyncTask
public class ShowResponceForAccept extends AsyncTask<String, String, String>{
private ProgressDialog pDialog;
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
pDialog = ProgressDialog.show(activity, "Sending Request", "getting Responce.", true, false);
}
@Override
protected String doInBackground(String... arg0) {
// TODO Auto-generated method stub
// ShortList sendandget = new ShortList();
// String resp = sendandget.getResponceFromServer(Appid, null, Uid);
ShortList sendandget = new ShortList();
String resp = sendandget.getResponceFromServer(Appid,"",Uid);
//Thread.sleep(10000);
//String x="Your Request Accepted";
return resp;
//return x;
}
@Override
protected void onPostExecute(String resp) {
// TODO Auto-generated method stub
pDialog.dismiss();
String x = resp;
Toast.makeText(mContext, x, Toast.LENGTH_LONG).show();
}
}
這也是在同一個適配器類。
任何人都可以幫助我...？
