이 예에서는 Google지도를 구현했습니다. 이 응용 프로그램에는 탐색 서랍도 있습니다. 탐색 창에는 앱의 메뉴 역할을하는 목록보기가 있습니다. 메뉴 항목은 "map"과 "Fragment 1"입니다. 탐색 창에서 '지도'를 선택하면 화면이 2 초 동안 정지 한 후 탐색 서랍이 뒤로 밀려지도가로드됩니다. 이것은 사용자 경험에 좋지 않습니다. 이 상황에서 앱이 정지되는 것을 방지 할 수있는 방법이 있습니까? 탐색 창을 정상적으로 작동시키고 사용자의지도가 아직로드 중임을 나타내는 방법?Google지도를로드하는 동안 얼어 붙는 것을 방지하는 방법

MainActivity.java : 여기에 코드입니다.
나는 이렇게 했어.하지만 같은 결과. 대신 당신은 아마 직접지도보기 클래스를 사용해야합니다 SupportMapFragment를 사용
final SupportMapFragment[] mapFragment = new SupportMapFragment[1];
Runnable runnable = new Runnable() {
@Override
public void run() {
mapFragment[0] = (SupportMapFragment) getChildFragmentManager()
.findFragmentById(R.id.map);
}
};
try {
Thread thread = new Thread(runnable);
thread.start();
thread.join();
mapFragment[0].getMapAsync(MapFragment.this);
} catch (InterruptedException e) {
e.printStackTrace();
}
당신은 어떤 일을 변경하지 않은? –
