使用复选框在Android的AlertDialog [英] AlertDialog with checkbox In android

问题描述

我是新来的Andr​​oid。我工作的一个应用程序中，我需要显示一个对话框，用户可以选择多个项目。为此，我想一个复选框添加到每个项目在对话框中。

I am new to Android. I am working on an app in which I need to show a dialog in which user can select more than one item. For this I want to add a checkbox to each item in the dialog.

我看了下帖子的计算器：

I read following posts on StackOverflow:

其中一个职位描述如何创建XML定义除复选框以膨胀的对话框中，但我无法得到它的工作。

.setTitle("Select The Difficulty Level")
.setMultiChoiceItems(items, null, new DialogInterface.OnMultiChoiceClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int indexSelected, boolean isChecked) {
        if (isChecked) {
            // If the user checked the item, add it to the selected items
            seletedItems.add(indexSelected);
        } else if (seletedItems.contains(indexSelected)) {
            // Else, if the item is already in the array, remove it
            seletedItems.remove(Integer.valueOf(indexSelected));
        }
    }
}).setPositiveButton("OK", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int id) {
        //  Your code when user clicked on OK
        //  You can write the code  to save the selected item here
    }
