我想保留一次选择多个联系人号码的能力，使用checkbox. 我使用了一个带有两个textview和一个的自定义布局checkbox来为列表创建一行。我已经成功地用联系人填写了列表，但是当用户单击完成按钮时，我无法配置如何检索已选中（勾选）联系人的电话号码。请指导我。

您应该为每个复选框设置一个标签以及一个 onCheckChanged 侦听器或类似的东西。当状态变为选中时，只需获取与该复选框关联的标签（这样您就会知道列表中的哪些元素被选中）。然后，您必须重新查询以获取该列索引处的电话号码。您已经在此处存储了您的电话号码

String phoneNumber = phones
                    .getString(phones
                                  .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
