AlertDialog MultiChoiceItems监听器问题 [英] AlertDialog MultiChoiceItems Listener problems

问题描述

我目前使用的AlertDialog.builder创建multichoice列表中的用户（复选框）。这个伟大的工程，但我们希望其中一个按钮来取消选择列表中的所有其他人。

I am currently using the AlertDialog.builder to create a multichoice list for the user (checkboxes). This works great, except we want one of the buttons to deselect all of the others in the list.

builder.setMultiChoiceItems(list, checked,
  new DialogInterface.OnMultiChoiceClickListener() {
   public void onClick(DialogInterface dialog,
     int item, boolean isChecked) {

    if(item == ANY_ITEM_BUT_0)
    {

     ((AlertDialog) dialog).getListView().setItemChecked(0, false);

    }
   }
  });

在使用真，它将成功地选中该复选框，但使用虚假不取消它时，（除非我有手动设置为true前手。）有，我应该使用，以检测当一个单独的侦听器用户点击这些？在我看来，有两个设置复选标记，一个在setItemChecked（0，真）;，以及一个由实际选择它

When using "true" it will successfully check the box, but when using false it does not uncheck it (unless i have manually set it to true before hand.) Is there a separate listener I should be using to detect when a user clicks these? It seems to me that there are two checkmarks set, one by the "setItemChecked(0, true);", and one by actually selecting it.

这是我发疯了几天，现在，任何帮助将大大AP preciated。

This has been driving me nuts for a couple days now, any help would be greatly appreciated.
