Android：從電話號碼中檢索聯系人姓名

Question

我想檢索與傳入電話號碼關聯的聯系人姓名。 當我在 broascastreceiver 中處理傳入號碼時，如果有一個帶有傳入呼叫者姓名的字符串，將對我的項目有很大幫助。

我認為這涉及使用 sql WHERE 子句作為過濾器的查詢，但我需要對聯系人進行排序嗎？ 一個例子或提示會有很大的幫助。

Answer 1

雖然這已經得到了解答，但這里是從數字中獲取聯系人姓名的完整功能。 希望它能幫助別人：

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;
}

[根據Marcus的評論更新 ]

你必須要求這個許可：

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

Answer 2

為此，您需要使用優化的PhoneLookup提供程序，如上所述。

將權限添加到AndroidManifest.xml ：

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

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;
}

Answer 3

這非常有用，這是我檢索調用者姓名，ID和照片的最終代碼：

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);
}

...然后用“輸入”（他們的照片作為InputStream），“name”和“contactId”做任何你想做的事。

此版本與Vikram.exe的答案相同，代碼是為了避免ANR

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();

}

Answer 5

使用以下方法傳遞接聽電話的聯系號碼。 此方法將檢查聯系人是否已保存在您的手機中。 如果保存聯系人，則它將返回聯系人姓名，否則返回字符串未知號碼

在您的廣播接收器類中添加此代碼

    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;
}

為此，我們可以使用PhoneLookup提供程序使用手機號碼獲取姓名或聯系方式。

為AndroidManifest.xml添加權限：

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

在您的活動中添加以下自定義 kotlin 方法，並使用所需的手機號碼調用該方法。

fun getContactNameByPhoneNumber(context: Context, phoneNumber: String): String? {
        var phone = phoneNumber
        if(phoneNumber != null && phoneNumber.length > 0 && phoneNumber[0].equals('+'))
            phone = phoneNumber.substring(3)

        val projection = arrayOf(
            ContactsContract.PhoneLookup.DISPLAY_NAME,
            ContactsContract.CommonDataKinds.Phone.NUMBER
        )
        val cursor = context.contentResolver.query(
            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            projection,
            ContactsContract.CommonDataKinds.Phone.NUMBER, null, null
        ) ?: return ""
        for (i in 0 until cursor.count) {
            cursor.moveToPosition(i)
            val nameFieldColumnIndex = cursor
                .getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME)
            val phoneFieldColumnIndex = cursor
                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)

            if(phone.equals(cursor.getString(phoneFieldColumnIndex)))
                return cursor.getString(nameFieldColumnIndex)
        }
        return "Unknown"
    }
