Phone.NUMBER爲所有聯繫人返回空

我試圖從具有API 23權限的聯繫人中獲取電話號碼，但電話號碼始終返回空字符串。獲取聯繫人的權限已被驗證，並且聯繫人顯示有效，但對於任何聯繫人而言，該電話號碼字段似乎不存在。「cr.query ...」似乎沒有帶回任何東西，因爲「while（phones.moveToNext）」從不顯示爲真。我正在使用下面的代碼來獲取電話號碼。任何想法爲什麼電話號碼不顯示任何聯繫人？Phone.NUMBER爲所有聯繫人返回空

   ContentResolver cr = getContentResolver(); 
       cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
       if (cursor.moveToFirst()) { 
        String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID)); 

        Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
          ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null); 
        while (phones.moveToNext()) { 
         String number = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
         int type = phones.getInt(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE)); 
         switch (type) { 
          case ContactsContract.CommonDataKinds.Phone.TYPE_HOME: 
           // do something with the Home number here... 
           break; 
          case ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE: 
           PhoneNumber = number; 
           break; 
          case ContactsContract.CommonDataKinds.Phone.TYPE_WORK: 
           // do something with the Work number here... 
           break; 
         } 
        } 
        phones.close(); 
       } 
       cursor.close();

UPDATE：不知道爲什麼這種方法是行不通的，但發現另一種確實可行的方法。

 Uri result = data.getData(); 
     String id = result.getLastPathSegment(); 
     cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?", new String[] { id }, null); 
    int phoneIdx = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA); 

     if (cursor.moveToFirst()) { 
        PhoneNumber = cursor.getString(phoneIdx).toString(); 
       }

此方法工作正常。

沒有錯誤，只是空洞的手機串。我編輯了上面的帖子，展示了一種可行的方法。測試的手機是Nexus 6P，以防有所作爲。 – user2431174

你可以嘗試用下面的方法使用ContactContract拿到電話號碼的詳細信息：

private void retrieveContactNumber() { 

    String contactNumber = null; 

    // getting contacts ID 
    Cursor cursorID = getContentResolver().query(uriContact, 
      new String[]{ContactsContract.Contacts._ID}, 
      null, null, null); 

    if (cursorID.moveToFirst()) { 

     contactID = cursorID.getString(cursorID.getColumnIndex(ContactsContract.Contacts._ID)); 
    } 

    cursorID.close(); 

    Log.d(TAG, "Contact ID: " + contactID); 

    // Using the contact ID now we will get contact phone number 
    Cursor cursorPhone = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
      new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER}, 

      ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " + 
        ContactsContract.CommonDataKinds.Phone.TYPE + " = " + 
        ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, 

      new String[]{contactID}, 
      null); 

    if (cursorPhone.moveToFirst()) { 
     contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
    } 

    cursorPhone.close(); 

    Log.d(TAG, "Contact Phone Number: " + contactNumber); 
}
