得到在HTC欲望的联系人列表android

Question

我想获得列表视图上的联系人列表。我可以使用这个代码来显示。

private ContactList getContacts() { 
     ContactList contactList = new ContactList(); 
     Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; 
     String[] projection = new String[] { 
       ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, 
       ContactsContract.CommonDataKinds.Phone.NUMBER }; 

     Cursor people = getContentResolver().query(uri, projection, null, null, 
       null); 

     int indexName = people 
       .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME); 
     int indexNumber = people 
       .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER); 

     people.moveToFirst(); 
     do { 
      Contact c = new Contact(); 
      String name = people.getString(indexName); 
      String number = people.getString(indexNumber); 
      Log.d("number", "" + number); 
      c.setDisplayName(name); 
      c.set_phoneNumber(number); 
      contactList.addContact(c); 
     } while (people.moveToNext()); 
     people.close(); 
     return contactList; 
    } 

但是当我尝试在HTC渴望c将其不能工作的代码。任何人都可以告诉我为什么。 ？ 什么是实际问题。以及如何解决它。
