Search contact by phone number
提问by Tiago Costa
In my app, user writes a phone number, and I want to find the contact name with that phone number?
在我的应用程序中，用户写了一个电话号码，我想找到该电话号码的联系人姓名？
I usually search the contacts like this:
我通常这样搜索联系人：
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?
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？
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...
还是我必须通过所有联系人查看是否有给定的电话号码？但我相信这样会很慢......

If you want the complete code:
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;
}

You should have a look at the recommended ContactsContract.PhoneLookupprovider
你应该看看推荐的ContactsContract.PhoneLookupprovider
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.
表示查找电话号码的结果的表格，例如来电显示。要执行查找，您必须将要查找的数字附加到 CONTENT_FILTER_URI。这个查询是高度优化的。
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
resolver.query(uri, new String[]{PhoneLookup.DISPLAY_NAME,...
