Question

我只是将所有联系人列表添加到对象（PhoneBookContact）：

 private static final Uri                         PURI      = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
 private static final String                      PID       = ContactsContract.CommonDataKinds.Phone._ID;
 private static final String                      PNAME     = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME;
 private static final String                      PNUM      = ContactsContract.CommonDataKinds.Phone.NUMBER;


 String[] projection = new String[]{PID, PNAME, PNUM};

 String sortOrder = PNAME + " COLLATE LOCALIZED ASC";

 Cursor people = mContext.getContentResolver().query(PURI, projection, null, null, sortOrder);

 int indexid = people.getColumnIndex(PID);
 int indexName = people.getColumnIndex(PNAME);
 int indexNumber = people.getColumnIndex(PNUM);

 people.moveToFirst();
 do {
    PhoneBookContact phoneBookContact = new PhoneBookContact();
    phoneBookContact.setmCursorId(people.getLong(indexid));
    phoneBookContact.setmDisplayName(people.getString(indexName));
    phoneBookContact.setmPhoneNumber(UriFactory.formatNumberToInternational(people.getString(indexNumber)));
    phoneList.put(phoneBookContact.getmPhoneNumber(), phoneBookContact);
 } while (people.moveToNext());
 people.close();

要从Android通讯录中获取用户的照片，我使用此方法：

   public static Uri loadContactPhotoUri(ContentResolver contentResolver, long id) {
      try {
         Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
         return person;
      }
      catch (Exception e) {
         e.printStackTrace();
         return null;
      }
   }

最后，此代码为特定用户提供此URI：

content://com.android.contacts/contacts/5907

由于我使用ContactsContract.CommonDataKinds.Phone._ID id调用此URI，因此无法成功获取用户的照片。实际上，它应该是ContactsContract.Contacts._ID的id。如何查询用户的照片并解决此问题？

Answer 1

您必须使用ContactsContract.CommonDataKinds.Phone.CONTACT_ID来保存Contacts表的cursorID，而不是ContactsContract.CommonDataKinds.Phone._ID。它解决了我的问题。
