如何在onPrepareDialog中设置setSingleChoiceItems的内容？ [英] how to set contents of setSingleChoiceItems in onPrepareDialog?

问题描述

在onCreateDialog中的人，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();
    }

这是非常有用的。

但请注意线

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

phoneNums假设每次弹出对话框时都会更改
I我已经在PrepareDialog方法上覆盖了，但我不知道如何为它分配新的值
，也没有setSingleChoiceItems。

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.

这里是我的onPrepareDialog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;
}

有什么解决方案？
感谢提前的家伙。

What is the solution? thanks in advance guys.

推荐答案

您需要使用 getListView 方法。然后在返回的对象上使用 setItemChecked 方法。示例：

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


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