Question

entsprechende Cursor-Aufzeichnungen übereinstimmen In onCreate Ich habe ein Cursor genannt Telefone:

// this query only return contacts with phone number and is not duplicated 
     phones = getContentResolver().query(
//    the table to query 
       ContactsContract.Contacts.CONTENT_URI, 
//    the columns to return 
       null, 
//    selection criteria : 
// we only want contacts that have a name and a phone number. If they have a phone number, the value is 1 (if not, it is 0) 
       ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '" + ("1") + "'" + " AND " + ContactsContract.Contacts.HAS_PHONE_NUMBER + "=1", 
//    selection criteria 
       null, 
//    display in ascending order 
       ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC"); 

// phones.getCount returns 134 records, which is the correct number of contacts with corresponding phone number. 

ich Schleife durch die Namen aller 134 Kontakte zu erhalten:

if (phones != null) { 


      if (phones.getCount() == 0) { 
       Toast.makeText(MainActivity.this, "No contacts in your contact list.", Toast.LENGTH_LONG).show(); 
      } 

      while (phones.moveToNext()) { 


       String name = phones.getString(phones.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 

Jetzt muss ich die 134 passenden Telefonnummern bekommen. Knapp unterhalb der letzten Zeile oben, noch in der While Loop, mache ich einen neuen Cursor, phonestwo:

// phoneContactId returns 134 records, which is the correct number - it matches the number of contacts with corresponding phone numbers. 
     String phoneContactId = phones.getString(phones.getColumnIndexOrThrow(BaseColumns._ID)); 


     phonestwo = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
            null, 
            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", 
            new String[]{phoneContactId}, 
            null); 



     while (phonestwo.moveToNext()) { 
     int phoneType = phonestwo.getInt(phonestwo.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.TYPE)); 
     String phoneNumber = phonestwo.getString(phonestwo.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER)); 


//For every contact in the phonebook, show the name and number 
     SelectContact selectContact = new SelectContact(); 
     selectContact.setName(name); 
     selectContact.setPhone(phoneNumber); 
     selectContacts.add(selectContact); 
          } 


         } 

        } 

        phones.close(); 
        return null; 
       } 

In meinem Logcat,

I 134 "Telefone" Aufzeichnungen haben, was richtig ist.

Ich habe 134 "phoneContactId" Datensätze, die korrekt ist.

Ich habe 1 und manchmal 2 "phonestwo" Datensätze. Aber ich möchte, dass die Anzahl der Phonestwo-Einträge 134 beträgt, die der entsprechenden 134 Telefonnummern. Irgendwelche Ideen?

Hier ist ein Ausschnitt aus meiner logcat:
