android search widget을 사용하여 검색 검색 후 올바른 위치가 표시되지 않습니다.

Question

내 안드로이드 응용 프로그램에서 목록보기를 검색하고 싶습니다. 그래서이 android 검색보기 위젯을 사용했습니다. 검색을 성공적으로 구현했으나 검색 후 문제가 발생했습니다. 내가 검색 할 때 검색 결과가 필터링되지만 필터링 된 항목을 클릭하면 잘못된 위치가 표시됩니다. 도와주세요.

Answer 1

문제는 검색 어댑터 coverList내부 배열 필터링된다는 점이다. 따라서 어댑터에서 항목의 위치는 정상입니다.

그런 다음 어댑터 (클래스) mList의 외부을 호출합니다. 그 시점에서 필터가없는 원래 배열을보고 있습니다. 그래서 입장이 잘못되었습니다.

어댑터의 필터링 된 배열에서 연락처를 복구해야합니다. 따라서 귀하의 MainActivity :

mcontact.setOnItemClickListener(new AdapterView.OnItemClickListener() 
    { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
     { 
      number = mMyContactsAdapter.getItem(position).getNumber(); 
      email = mMyContactsAdapter.getItem(position).getEmail(); 
      view.setSelected(true); 
    } 
}); 

Answer 2

mMyContactsAdapter.getItem(position); 
Contacts mList = getSearchResults(sv.getQuery().toString()).get(position); 
number = mList.get(position).getNumber(); 
email = mList.get(position).getEmail();
