按电话号码搜索联系人

发布于 2024-09-18 18:38:27 字数 320 浏览 9 评论 0原文

在我的应用程序中，用户输入一个电话号码，我想查找该电话号码的联系人姓名？

我通常这样搜索联系人：

Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);

但我这样做是为了访问所有联系人...在这个应用程序中，我只想获取给定电话号码的联系人姓名...如何限制查询？

或者我是否必须遍历所有联系人并查看是否有给定的电话号码？但我相信这样会很慢......

In my app, user writes a phone number, and I want to find the contact name with that phone number?

I usually search the contacts like this:

Cursor cur = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
            null, null, null, null);

But I do this to access all contacts... In this app I only want to get the contact name of the given phone number... How can I restrict the query?

Or do I have to go trough all contacts and see if any has the given phone number? But I believe that this can be very slow this way...

如果你想要完整的代码：

public String getContactDisplayNameByNumber(String number) {
    Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
    String name = "?";

    ContentResolver contentResolver = getContentResolver();
    Cursor contactLookup = contentResolver.query(uri, new String[] {BaseColumns._ID,
            ContactsContract.PhoneLookup.DISPLAY_NAME }, null, null, null);

    try {
        if (contactLookup != null && contactLookup.getCount() > 0) {
            contactLookup.moveToNext();
            name = contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
            //String contactId = contactLookup.getString(contactLookup.getColumnIndex(BaseColumns._ID));
        }
    } finally {
        if (contactLookup != null) {
            contactLookup.close();
        }
    }

    return name;
}

If you want the complete code:

public String getContactDisplayNameByNumber(String number) {
    Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
    String name = "?";

    ContentResolver contentResolver = getContentResolver();
    Cursor contactLookup = contentResolver.query(uri, new String[] {BaseColumns._ID,
            ContactsContract.PhoneLookup.DISPLAY_NAME }, null, null, null);

    try {
        if (contactLookup != null && contactLookup.getCount() > 0) {
            contactLookup.moveToNext();
            name = contactLookup.getString(contactLookup.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
            //String contactId = contactLookup.getString(contactLookup.getColumnIndex(BaseColumns._ID));
        }
    } finally {
        if (contactLookup != null) {
            contactLookup.close();
        }
    }

    return name;
}

您应该查看推荐的 ContactsContract.PhoneLookup 提供商

A表，表示查找电话号码的结果，例如呼叫者 ID。要执行查找，您必须将要查找的号码附加到 CONTENT_FILTER_URI。该查询经过高度优化。

Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
resolver.query(uri, new String[]{PhoneLookup.DISPLAY_NAME,...

You should have a look at the recommended ContactsContract.PhoneLookup provider

A table that represents the result of looking up a phone number, for example for caller ID. To perform a lookup you must append the number you want to find to CONTENT_FILTER_URI. This query is highly optimized.

Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
resolver.query(uri, new String[]{PhoneLookup.DISPLAY_NAME,...
