Question

我想在列表上设置对话框。当用户选择列表项时，它应该显示警告框“是”/“否”。我试过这样的。但它给出 BadTokenException

     @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        HashMap<String, String> itemAtPosition = (HashMap<String, String>) l.getItemAtPosition(position);
        HashMap<String, String> hashMap = itemAtPosition;
        keyword = hashMap.get("routeCode");
        positions = position;
        if(itinerarySelection.equals("1") || itinerarySelection.equals(" ") ||itinerarySelection == null){
            AlertDialog.Builder routeDefaultQue = new AlertDialog.Builder(this);
            routeDefaultQue.setMessage("Do you want to set this route as defalut route?");
            routeDefaultQue.setCancelable(false);
            routeDefaultQue.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
//                      String[] nameFilds = {"BusinessUnit","ExecutiveCode","VisitNumber","TerritoryCode","RouteCode","VisitDate","StartTime","Status","UploadedOn","UploadedBy"};
//                      String[] valuesFilds = {strBusinessUnit,strExecutive,"",strTerritoryCode,keyword,DateFormat.getInstance().format(date),DateFormat.getTimeInstance(DateFormat.SHORT).format(date),"1",DateFormat.getInstance().format(date),strExecutive};
//                      insertRecords("", nameFilds, valuesFilds);
//                      getListView().getChildAt(positions).setBackgroundColor(R.color.red);
                }
            });
            routeDefaultQue.setNegativeButton("No", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
                }
            });

            routeDefaultQue.setTitle("Default Route setup...");
            routeDefaultQue.setIcon(R.drawable.icon);
            routeDefaultQue.show();
         }

这是我在activityGroup上的这个列表。

这是错误

请帮帮我

提前致谢

Answer 1

AlertDialog.Builder routeDefaultQue = new AlertDialog.Builder(yourRunningActivity.this);

试试这个

Answer 2

你在这里使用错误的context，尝试使用你传递给AlertDialog.Builder的正确上下文你的问题将会完成。

您已使用此

AlertDialog.Builder routeDefaultQue = new AlertDialog.Builder(this);

在onListItemClick内，你传递this来创建错误的AlertDialog.Builder，你必须在那里传递Activity或Application的上下文。

Answer 3

如果Tab的内容是Activity，那么您需要将TabActivity的上下文传递给警报对话框而不是内容活动的上下文。

试试这个：

AlertDialog.Builder routeDefaultQue = new AlertDialog.Builder(getParent());

Answer 4

请尝试以下代码

AlertDialog.Builder routeDefaultQue = new AlertDialog.Builder(getApplicationContext());

列表onListItemClick（）方法上的对话框..它给出了BadTokenException
