我正在尝试通过提供电话号码来获取未本地存储在我的设备上但在 Microsoft Exchange ActiveSync 目录中找到的联系人。我关注了 igorepst 的帖子，该帖子提供了一个简单的按名称检索联系人的解决方案，并且我尝试对其进行修改以满足我的需要，但我被卡住了。
这是代码让我按名称获取联系人

现在，为了按号码获取联系人，我将搜索方法（MainActivity）的第一个 Uri 更改为：
Uri uri = ContactsContract.Contacts.CONTENT_FILTER_URI.buildUpon().appendEncodedPath("SOME PHONE NUMBER")
.appendQueryParameter(ContactsContract.DIRECTORY_PARAM_KEY, idStr).build();
但它永远找不到任何结果。我在这里错过了什么？
