Android:从电话号码中检索联系人姓名

Question

我想检索与传入电话号码关联的联系人姓名.当我处理broascastreceiver中的传入号码时,有一个带有传入呼叫者姓名的字符串将极大地帮助我的项目.

我认为这涉及使用sql WHERE子句作为过滤器的查询,但是我是否需要对联系人进行排序？一个例子或提示将是非常有帮助的.

Answer 1

虽然这已经得到了解答,但这里是从数字中获取联系人姓名的完整功能.希望它能帮助别人:

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;
}

你必须要求这个许可:

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

Answer 2

为此,您需要使用优化的PhoneLookup提供程序,如上所述.

将权限添加到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

这非常有用,这是我检索调用者姓名,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);
}

...然后用"输入"(他们的照片作为InputStream),"name"和"contactId"做任何你想做的事.

以下是列出您可以访问的约15个左右列的文档,只需将它们添加到上面代码开头附近的投影中:http: //developer.android.com/reference/android/provider/ContactsContract. PhoneLookup.html
