我有一些标记并更新了这个标记的位置（我发送服务器请求）。但是，当我放置新标记时，我做到了这一点：
public void putMarkers() {
Singleton si = Singleton.getInstance();
Drawable newMarker = getApplication().getResources().getDrawable(R.drawable.znacznik_new);
Drawable newMarkerAktywny = getApplication().getResources().getDrawable(R.drawable.ikona_znacznik_pojazd_aktywna);
mResourceProxy = new DefaultResourceProxyImpl(getApplicationContext());
activeOverlayItemArray.clear();
anotherOverlayItemArray.clear();
for(ObjectDefExtends object : si.getListaVisible()){
if (object.lon == null) object.lon = 0.0;
if (object.lat == null) object.lat = 0.0;
/*if (si.getListaVisible().get(a).lon!=null&&si.getListaVisible().get(a).lon!=0)*/
if (object == Singleton.getInstance().currentObject) {
activeOverlayItemArray.add(new OverlayItem(object.name,
object.name, new GeoPoint(object.lat, object.lon)));
} {
anotherOverlayItemArray.add(new OverlayItem(object.name,
object.name, new GeoPoint(object.lat, object.lon)));
}
}
anotherItemizedIconOverlay = new ItemizedIconOverlay<>(anotherOverlayItemArray, newMarker, new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
@Override
public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
indexs = index + 1;
mPin.hideInfoWindow();
mapView.getOverlays().remove(mPin);
mPin.setPosition(anotherItemizedIconOverlay.getItem(index).getPoint());
mPin.setTitle(anotherItemizedIconOverlay.getItem(index).getTitle());
try {
tvStreetName.setText(getCityAndStreet(anotherItemizedIconOverlay.getItem(index).getPoint().getLatitude(), anotherItemizedIconOverlay.getItem(index).getPoint().getLongitude(), getBaseContext()));
} catch (IOException e) {
e.printStackTrace();
}
currentNumber = index;
Singleton.getInstance().setCurrentObjectIndex(currentNumber);
Log.e("azymut ", Singleton.getInstance().getListaODE().get(currentNumber).azimuth + "");
updateEverything();
mPin.showInfoWindow();
mapView.getOverlays().add(mPin);
return true;
}
@Override
public boolean onItemLongPress(final int index, final OverlayItem item) {
return false;
}
}, mResourceProxy);
activeItemizedIconOverlay = new ItemizedIconOverlay<>(activeOverlayItemArray, newMarkerAktywny, new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
@Override
public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
mPin.hideInfoWindow();
mapView.getOverlays().remove(mPin);
mPin.setPosition(activeItemizedIconOverlay.getItem(index).getPoint());
mPin.setTitle(anotherItemizedIconOverlay.getItem(index).getTitle());
currentNumber = index;
Singleton.getInstance().setCurrentObjectIndex(currentNumber);
updateEverything();
mPin.showInfoWindow();
mapView.getOverlays().add(mPin);
return true;
}
@Override
public boolean onItemLongPress(final int index, final OverlayItem item) {
return false;
}
}, mResourceProxy);
for (int a = 0; a < anotherItemizedIconOverlay.size(); a++) {
if (si.listaVisible.indexOf(Singleton.getInstance().currentObject) == a) {
activeItemizedIconOverlay.removeAllItems();
activeItemizedIconOverlay.addItem(new OverlayItem(
si.getListaVisible().get(a).name,
si.getListaVisible().get(a).name,
new GeoPoint(si.getListaVisible().get(a).lat,
Singleton.getInstance().getListaVisible().get(a).lon)));
mPin.setPosition(anotherItemizedIconOverlay.getItem(a).getPoint());
mPin.setAnchor(0.5f, 0.5f);
mPin.setIcon(getResources().getDrawable(R.drawable.pusty));
mPin.setTitle(anotherItemizedIconOverlay.getItem(a).getTitle());
break;
}
}
runOnUiThread(new Runnable() {
@Override
public void run() {
mapView.getOverlays().add(mPin);
mapView.getOverlays().add(anotherItemizedIconOverlay);
mapView.getOverlays().add(activeItemizedIconOverlay);
mapView.invalidate();
}
});
}
这就是我更新职位的方式：
public void aktualizujCoInterwal(int interwal) {
aktualizacja = true;
executor = Executors.newScheduledThreadPool(1);
executor.scheduleAtFixedRate(new Runnable() {
public void run() {
Log.e("aktualizacja", "akt");
if (timeout) {
executor.shutdown();
timedOut();
} else {
aktualizacjaDanych();
}
}
}, 0, interwalAktualizacji, TimeUnit.SECONDS);
}
public void aktualizacjaDanych() {
SmokConnectorImplPortBinding srv1 = new SmokConnectorImplPortBinding(null, URL);
try {
Singleton si = Singleton.getInstance();
ObjectLastStateResult lastState2;
lastState2 = srv1.GetObjectLastState(uid, now);
int rozmiarNowych = lastState2.objectState.size();
int value = (Integer) lastState2.getProperty(0);
if (value != 1) {
timeout = true;
executor.shutdownNow();
timedOut();
} else {
int rozmiarObecnych = si.getListaODE().size();
runOnUiThread(new Runnable() {
@Override
public void run() {
//czyszczenie poprzednio dodanych na mape obiektow
anotherOverlayItemArray.clear();
activeOverlayItemArray.clear();
mapView.getOverlays().clear();
}
});
for (int i = 0; i < rozmiarNowych; i++) {
for (int b = 0; b < rozmiarObecnych; b++) {
if (si.getListaODE().get(b).id.equals(lastState2.objectState.get(i).id)) {
if (lastState2.objectState.get(i).lon != null && lastState2.objectState.get(i).lon.doubleValue() != 0) {
if (lastState2.objectState.get(i).lat != null && lastState2.objectState.get(i).lat.doubleValue() != 0) {
si.getListaODE().get(b).lat = lastState2.objectState.get(i).lat.doubleValue();
si.getListaODE().get(b).lon = lastState2.objectState.get(i).lon.doubleValue();
}
si.getListaODE().get(b).azimuth = lastState2.objectState.get(i).azimuth.intValue();
si.getListaODE().get(b).lastDataTime = lastState2.objectState.get(i).dateTime;
si.getListaODE().get(b).statusGPS = lastState2.objectState.get(i).statusGPS;
try {
si.getListaODE().get(b).mySensors = lastState2.objectState.get(i).sensors.sensor;
} catch (NullPointerException e) {
Log.e("Null", "sensory są puste");
}
si.getListaODE().get(b).description1 = lastState2.objectState.get(i).description1;
si.getListaODE().get(b).description2 = lastState2.objectState.get(i).description2;
si.getListaODE().get(b).velocity = lastState2.objectState.get(i).velocity.intValue();
try {
si.getListaODE().get(b).icons = lastState2.objectState.get(i).sensors.icon;
} catch (NullPointerException e) {
Log.e("Null", "sensory są puste");
}
}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
now = DateTime.now();
Singleton si = Singleton.getInstance();
if (si.getListaVisible().size() > 0) {
obiektyNaMape();
updateEverything();
}
showCurrentMarker();
}
来自服务器的所有对象都有一个方位角，我从所有标记中旋转一个标记图标，当首先完成更新时，我会看到一个默认标记，然后我看到一个旋转标记。
