Java Android：如何通过电话号码将联系人存储在一个目录中？

我试图通过提供电话号码来获取并非本地存储在我的设备上，而是在Microsoft Exchange ActiveSync目录中找到的联系人。我遵循了这一点，它提供了一个按姓名检索联系人的简单解决方案，我尝试对其进行修改以满足我的需要，但我被卡住了

这是密码让我按姓名抓取联系人

            }
        }
        if (bld.length() == 0) {
            String result = "Cannot find matching contacts for the string '" + searchString + "'";
            Log.d(TAG, result);
            return result;
        }
        return bld.toString();
    }
}

现在，为了按号码抓取联系人，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();

---

但它从未找到任何结果。我遗漏了什么？

我发现了问题所在。该目录不支持按数字搜索，只支持按名称搜索。根据谷歌文档，一个目录必须支持Contacts.CONTENT\u FILTER\u URI。但是，CommonDataTypes.Phone.CONTENT\u FILTER\u URI是可选的。我发现了这个问题。该目录不支持按数字搜索，只支持按名称搜索。根据谷歌文档，一个目录必须支持Contacts.CONTENT\u FILTER\u URI。但是，CommonDataTypes.Phone.CONTENT_FILTER_URI是可选的。

    Uri uri = ContactsContract.Contacts.CONTENT_FILTER_URI.buildUpon().appendEncodedPath("SOME PHONE NUMBER")
        .appendQueryParameter(ContactsContract.DIRECTORY_PARAM_KEY, idStr).build();
