Android:从电话号码中检索联系人姓名 [英] Android: Retrieve contact name from phone number

问题描述

我想检索与传入电话号码相关联的联系人姓名.当我在广播接收器中处理传入号码时，有一个带有来电者姓名的字符串将极大地帮助我的项目.

I would like to retrieve the name of a contact associated with an incoming telephone number. As I process the incoming number in the broascastreceiver having a String with the name of the incoming caller would help my project greatly.

我认为这涉及使用 sql WHERE 子句作为过滤器的查询，但我需要对联系人进行排序吗?一个例子或提示会很有帮助.

I would think this involves a query using the sql WHERE clause as a filter, but do I need to sort the contacts? An example or hint would be of great assistance.

推荐答案

为此，您需要按照描述使用优化的 PhoneLookup 提供程序.

For that you need to use the optimized PhoneLookup provider as described.

在AndroidManifest.xml中添加权限:

<uses-permission android:name="android.permission.READ_CONTACTS"/>

那么:

public String getContactName(final String phoneNumber, Context context)
{
    Uri uri=Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,Uri.encode(phoneNumber));

    String[] projection = new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME};

    String contactName="";
    Cursor cursor=context.getContentResolver().query(uri,projection,null,null,null);

    if (cursor != null) {
        if(cursor.moveToFirst()) {
            contactName=cursor.getString(0);
        }
        cursor.close();
    }

    return contactName;
}
