AUTO Navigation SDK가 기기 위치 및 현지 시간에 따라 적절한 모드를 결정할 수 있습니다.
FORCE_NIGHT: 야간 모드를 강제로 사용 설정합니다.
FORCE_DAY: 주간 모드를 강제로 사용 설정합니다.
다음 예는 탐색 프래그먼트 내에서 야간 모드를 강제로 사용 설정하는 방법을 보여줍니다.
// Force night mode on.
mNavFragment.setForceNightMode(FORCE_NIGHT);
경로 목록 표시
먼저 뷰를 만들고 계층 구조에 추가합니다.
setupDirectionsListView(){
// Create the view.
DirectionsListView directionsListView = new DirectionsListView(getApplicationContext());
// Add the view to your view hierarchy.
ViewGroup group = findViewById(R.id.directions_view);
group.addView(directionsListView);
// Add a button to your layout to close the directions list view.
ImageButton button = findViewById(R.id.close_directions_button); // this button is part of the container we hide in the next line.
button.setOnClickListener(
v -> findViewById(R.id.directions_view_container).setVisibility(View.GONE));
}
NaviagtionView에서처럼 수명 주기 이벤트를 DirectionsListView에
전달해야 합니다. 예를 들면 다음과 같습니다.
사용자 인터페이스가 너무 많은 정보로 인해 혼잡해지면 기본 경로보다 적은 대체 경로 (2개)를 표시하거나 대체 경로를 전혀 표시하지 않음으로써 혼란을 줄일 수 있습니다. 경로를 가져오기 전에 다음 열거형 값 중 하나로 RoutingOptions.alternateRoutesStrategy() 메서드를 호출하여 이 옵션을 구성할 수 있습니다.
열거형 값
설명
AlternateRoutesStrategy.SHOW_ALL
기본값입니다. 최대 2개의 대체 경로를 표시합니다.
AlternateRoutesStrategy.SHOW_ONE
대체 경로 하나를 표시합니다 (사용 가능한 경우).
AlternateRoutesStrategy.SHOW_NONE
대체 경로를 숨깁니다.
예
다음 코드 예는 대체 경로를 모두 숨기는 방법을 보여줍니다.
RoutingOptions routingOptions = new RoutingOptions();
routingOptions.alternateRoutesStrategy(AlternateRoutesStrategy.SHOW_NONE);
navigator.setDestinations(destinations, routingOptions, displayOptions);
