如何在prepareDialog设置setSingleChoiceItems的内容？

问题描述

大家好，在onCreateDialog我有这样的：

Guys, in onCreateDialog i have this:

case DIALOG_REVIEW: {
    if (bundle.containsKey("POSITION")) {
    final int position = bundle.getInt("POSITION");
    ArrayList<String> alterNumbers = numbers.get(position);
    final String[] phoneNums = new String[alterNumbers.size()];
    for (int i = 0; i < alterNumbers.size(); i++) {
        phoneNums[i] = alterNumbers.get(i);
    }
    AlertDialog.Builder dialog = new AlertDialog.Builder(this);
    dialog.setTitle(names.get(position) + "'s number(s)");
    dialog.setSingleChoiceItems(phoneNums, 0,
        new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog,
                int which) {
            // get selected item and close the dialog
            String selectedNumber = phoneNums[which];
            updateUserSelectedNumber(position , selectedNumber);
            }
        });
    return dialog.create();
    }

这是工作和伟大的。

which is working and great.

但要注意行

dialog.setSingleChoiceItems(phoneNums, 0,
        new DialogInterface.OnClickListener() {

phoneNums是假设每一个对话框弹出时间来改变。我重写的prepareDialog方法，但我不知道如何分配新的值给它。并且也没有setSingleChoiceItems那里

phoneNums are suppose to be changing each time the dialog pops up.I've overriden onPrepareDialog method but I don't know how to assign new values to it.and also there is no setSingleChoiceItems there.

这是我在prepareDialog方法

here is my onPrepareDialog method

case DIALOG_REVIEW: {
    final int position = bundle.getInt("POSITION");
    ArrayList<String> alterNumbers = numbers.get(position);
    final String[] phoneNums = new String[alterNumbers.size()];
    for (int i = 0; i < alterNumbers.size(); i++) {
    phoneNums[i] = alterNumbers.get(i);
    }
    AlertDialog alertDialog = (AlertDialog) dialog;
    alertDialog.setTitle(names.get(position) + "'s number(s)");
    ???
    break;
}

解决方案是什么？在此先感谢球员。

What is the solution?thanks in advance guys.

推荐答案

您需要使用getListView方法从AlertDialog类。然后使用setItemChecked方法对返回的对象。例如：

You need to use getListView method from AlertDialog class. Then use setItemChecked method on returned object. Example:

alertDialog.getListView（）setItemChecked（1，真）。

alertDialog.getListView().setItemChecked(1, true);
