[java] 조각으로 Android 검색

나는 그것을 달성했다고 생각합니다 : 실제로 조각을 사용하고 작업 표시 줄에 검색 아이콘을 추가하여 조각 내에서 검색 할 수 있습니다. 요령은 액션 바, 액션 뷰, 리스너, 로더 및 어댑터를 사용하는 것입니다.

이것은 안드로이드 플랫폼 검색 메커니즘을 완전히 우회하지만 잘 작동합니다 (그러나 @Alex Lockwood가 설명하고 조각에 검색을 전달하는 작업으로 완료 할 수 있습니다). 활동의 경우 예상대로 의도에 반응하지 않지만 작동합니다. 사용자는 조각 내부를 검색 할 수 있습니다.

코드는 다음과 같습니다.

MenuItem item = menu.add("Search");
SearchView sv = new SearchView(getActionBar().getThemedContext());
item.setActionView(sv);
item.setIcon(R.drawable.ic_search);
item.setShowAsAction(MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW
        | MenuItem.SHOW_AS_ACTION_IF_ROOM);
sv.setOnQueryTextListener(new OnQueryTextListener() {
    @Override
    public boolean onQueryTextSubmit(String query) {
        //...
        return false;
    }
    @Override
