파일에서 좌표를로드하고 비동기 작업에서 내지도에 도형을 추가하고 싶습니다. 그러나 나는 오류를 겪고 있으며 왜 나는 모릅니다. 여기 내 코드입니다 :Google지도에 항목을 추가하는 중에 Android AsyncTask 오류가 발생했습니다.
private class shpLoading extends AsyncTask<GoogleMap, Void, String> {
ProgressDialog dialog;
@Override
protected String doInBackground(GoogleMap... params) {
ShpReader shpRead = new ShpReader();
GoogleMap map = params[0];
try {
shpRead.reading();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InvalidShapeFileException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for(LatLng a : shpRead.points())
map.addMarker(new MarkerOptions()
.position(a)
.draggable(false));
int i = 0;
for(List<LatLng> a: shpRead.lines()){
map.addPolyline(new PolylineOptions()
.addAll(a)
.width(3)
.color(Color.RED));
}
for(List<LatLng> a: shpRead.polygons()){
map.addPolygon(new PolygonOptions()
.addAll(a)
.strokeWidth(3)
.strokeColor(Color.RED)
.fillColor(0x3F00FF00));
}
return "Done";
}
@Override
protected void onPreExecute() {
dialog = new ProgressDialog(Measuring.this);
dialog.setMessage("Kraunama...");
dialog.setIndeterminate(true);
dialog.setCancelable(false);
dialog.show();
}
@Override
protected void onProgressUpdate(Void... values) {
}
@Override
protected void onPostExecute(String result) {
dialog.dismiss();
}
}
그리고 이것은 내가 코드를 실행하는 방법입니다
shpLoading load = new shpLoading();
load.execute(mMap);
MMAP
이 GoogleMap으로 변수입니다. 모든doInBackground 코드를
onPostExecute 메소드에 추가하고 변수
map을 전역 변수
mMap으로 변경하면 eveything이 작동하지만 백그라운드에서이 작업을 수행하고 동시에 로딩 대화 상자를 표시하려고합니다. 여기

그리고 어쩌면 파일에서 좌표를로드와 맵에 추가 할 좋은 방법은 아니다? 아마 이것을 할 수있는 더 좋은 방법이 있을까요?
당신이'ShpReader' 클래스를 보일 수 있는가? 또한 당신은'doInbackground'에서 ui를 업데이트 할 수 없습니다. – Raghunandan
DoInBackGround 메소드에서 수행하지 않아야 할 일이있는 것 같습니다. 그래서 DoInBackground 메소드가 메인 쓰레드에서 실행되지 않기 때문에 우리는 "Not on the main thread"를 가지고 있습니다. 또한 "누수 된 창"은 컨텍스트를 변경하기 전에 열려 있거나 닫히지 않은 대화 상자 /보기로 활동을 마무리해야합니다. –
'ShpReader'가 정상적으로 작동합니다. 그것은 내가 원하는대로 완벽하게 좌표를 반환합니다. 지도에 도형을 추가하는 중에 오류가 발생했습니다. 그래서, 어떻게 맵핑하기 위해 모든 도형을 추가하고 로딩 메시지를 동시에 표시해야합니까? 나는 AsyncTask가 완벽 할 것이라고 생각했다. – user2617937
