안드로이드 장치 오류에서 모든 연락처 가져 오기

Question

배경 서비스를 시작하는 phonegap으로 응용 프로그램을 작성 중이며 백그라운드 서비스에서 json 형식으로 모든 사용자 연락처를 가져 오는 방법이 호출됩니다. 다음은

http://code.tutsplus.com/tutorials/build-a-contacts-application-with-jquery-mobile-the-android-sdk-part-1--mobile-5727 

코드 : 여기

는에서 입수 한과 코드 오전 테스트입니다

protected JSONObject initialiseLatestResult() { 
    // TODO Auto-generated method stub 
    final String ContactData = ContactUtility.getAllContactDisplaysJSON(getContentResolver()); 
    return null; 
} 

내가 얻을 :과 같이 다른 클래스에서 호출

public static String getAllContactDisplaysJSON(ContentResolver contentResolver){ 
    // Obtain all ContactDisplay objects from database and sort them 
    ArrayList<ContactDisplay> list = getAllContactDisplays(contentResolver); 
    Collections.sort(list); 

    // Populate the data structure consisting of ContactList-ContactGroup-ContactDisplay objects 
    // Start with initializing some variables 
    ContactList contactList = new ContactList(); 
    String key = ""; 
    ArrayList<ContactDisplay> values = new ArrayList<ContactDisplay>(); 
    ContactGroup group = null;  
    StringWriter writer = new StringWriter(); 

    // Process the list ContactDisplay objects to construct the data structure 
    if(list != null && !list.isEmpty()){    
     for(ContactDisplay display:list){ 
      if(!display.getKey().equals(key)){ 
       if(values.size() > 0){ 
        group = new ContactGroup(); 
        group.setKey(key); 
        group.setValues(values); 
        contactList.getContacts().add(group); 
       } 
       key = display.getKey(); 
       values = new ArrayList<ContactDisplay>();          
      } 
      values.add(display); 
     } 
     // Add the last group 
     if(values.size() > 0){ 
      group = new ContactGroup(); 
      group.setKey(key); 
      group.setValues(values); 
      contactList.getContacts().add(group); 
     } 
    }else{ 
     return EMPTY_CONTACT_LIST; 
    } 

    // We have the data structure of ContactList-ContactGroup-ContactDisplay objects where 
    // contactList is the root level element. Write it to a JSON formatted string using 
    // org.codehaus.jackson.map.ObjectMapper. 
    try{ 
     ObjectMapper mapper = new ObjectMapper(); 
     mapper.writeValue(writer, contactList); 
    }catch(Exception e){ 
     return EMPTY_CONTACT_LIST; 
    } 
    return writer.toString();    
} 

logcat의 다음 오류 :

안드로이드 (자바) 그래서 난 정말

Answer 1

당신이 내 코드를 통해 연락처 이름과 전화 번호를 가져 오기 및 이미지를 가져 오기하려면 다음 말해 당신이 할 수있는 무슨 일이 일어나고 있는지 이해하지에 오전 새로운 모든 데이터를 객체 arraylist에 저장하고 사용자 정의 어댑터에 표시 할 수 있습니다.

try { 
        Cursor phones = getContentResolver().query(
          ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
          null, null, null, null); 

        while (phones.moveToNext()) { 
    //you can define String name and phone number globally use 
         String name = phones 
           .getString(phones 
             .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); 
         Log.d("NAME", name); 

         String phoneNumber = phones 
           .getString(phones 
             .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 


         } 


        } 
        phones.close(); 

       } catch (Exception e) { 

       }
