Android：从电话号码中检索联系人姓名

Android: Retrieve contact name from phone number

提问by Noah Seidman

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.

我想检索与传入电话号码相关联的联系人姓名。当我在 broascastreceiver 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 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.

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

Although this has already been answered, but here is the complete function to get the contact name from number. Hope it will help others:

虽然这已经得到了回答，但这里是从号码中获取联系人姓名的完整功能。希望它会帮助其他人：

public static String getContactName(Context context, String phoneNumber) {
    ContentResolver cr = context.getContentResolver();
    Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
    Cursor cursor = cr.query(uri, new String[]{PhoneLookup.DISPLAY_NAME}, null, null, null);
    if (cursor == null) {
        return null;
    }
    String contactName = null;
    if(cursor.moveToFirst()) {
        contactName = cursor.getString(cursor.getColumnIndex(PhoneLookup.DISPLAY_NAME));
    }

    if(cursor != null && !cursor.isClosed()) {
        cursor.close();
    }

    return contactName;
}

You will have to ask for this permission:

您必须获得此许可：

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

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

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

为此，您需要使用优化的 PhoneLookup 提供程序，如上所述。

Add the permission to AndroidManifest.xml:

添加权限AndroidManifest.xml：

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

Then:

然后：

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;
}

This was very helpful, here's my final code for retrieving the caller's Name, id, and Photo:

这非常有帮助，这是我检索呼叫者姓名、ID 和照片的最终代码：

private void uploadContactPhoto(Context context, String number) {

Log.v("ffnet", "Started uploadcontactphoto...");

String name = null;
String contactId = null;
InputStream input = null;

// define the columns I want the query to return
String[] projection = new String[] {
        ContactsContract.PhoneLookup.DISPLAY_NAME,
        ContactsContract.PhoneLookup._ID};

// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));

// query time
Cursor cursor = context.getContentResolver().query(contactUri, projection, null, null, null);

if (cursor.moveToFirst()) {

    // Get values from contacts database:
    contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup._ID));
    name =      cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));

    // Get photo of contactId as input stream:
    Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long.parseLong(contactId));
    input = ContactsContract.Contacts.openContactPhotoInputStream(context.getContentResolver(), uri);

    Log.v("ffnet", "Started uploadcontactphoto: Contact Found @ " + number);            
    Log.v("ffnet", "Started uploadcontactphoto: Contact name  = " + name);
    Log.v("ffnet", "Started uploadcontactphoto: Contact id    = " + contactId);

} else {

    Log.v("ffnet", "Started uploadcontactphoto: Contact Not Found @ " + number);
    return; // contact not found

}

// Only continue if we found a valid contact photo:
if (input == null) {
    Log.v("ffnet", "Started uploadcontactphoto: No photo found, id = " + contactId + " name = " + name);
    return; // no photo
} else {
    this.type = contactId;
    Log.v("ffnet", "Started uploadcontactphoto: Photo found, id = " + contactId + " name = " + name);
}

... then just do whatever you want with "input" (their photo as an InputStream), "name", and "contactId".

...然后用“input”（他们的照片作为InputStream）、“name”和“contactId”做任何你想做的事情。

And here are the docs listing the ~15 or so columns you have access to, just add them to the projection near the start of the code up above: http://developer.android.com/reference/android/provider/ContactsContract.PhoneLookup.html

以下是列出您可以访问的大约 15 列左右的文档，只需将它们添加到上面代码开头附近的投影中即可：http: //developer.android.com/reference/android/provider/ContactsContract。电话查询.html

This version is the same as Vikram.exe's answer with code to avoid the ANR

此版本与 Vikram.exe 的答案相同，带有避免 ANR 的代码

interface GetContactNameListener {
    void contactName(String name);
}

public void getContactName(final String phoneNumber,final GetContactNameListener listener) {
    new Thread(new Runnable() {
        @Override
        public void run() {
            ContentResolver cr = getContentResolver();
            Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
            Cursor cursor = cr.query(uri, new String[]{ContactsContract.PhoneLookup.DISPLAY_NAME}, null, null, null);
            if (cursor == null) {
                return;
            }
            String contactName = null;
            if(cursor.moveToFirst()) {
                contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
            }

            if(cursor != null && !cursor.isClosed()) {
                cursor.close();
            }

            listener.contactName(contactName);
        }
    }).start();

}

Pass the contact number from which you are getting the call in the following method. This Method will check whether the contact is saved in your mobile or not. If the contact is saved then it will return the contact name otherwise it return a string unknown number

通过以下方法传递您接到电话的联系电话。此方法将检查联系人是否保存在您的手机中。如果联系人已保存，则返回联系人姓名，否则返回字符串未知号码

Add this code in your Broadcast receiver class

在您的广播接收器类中添加此代码

    public String getContactDisplayNameByNumber(String number,Context context) {
    Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
    name = "Incoming call from";

    ContentResolver contentResolver = context.getContentResolver();
    Cursor contactLookup = contentResolver.query(uri, null, null, null, null);

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

    return name;
}
