我的地图片段存在问题。当我加载地图时，我可以拖动地图，一切正常。在我的地图中，当我点击一个标记时，它会显示一个relativeLayout，当我触摸一个relativeLayout时，它会启动一个新活动，其中包含有关该标记的更多信息。
问题在于，当我按下设备的后退按钮时，它会返回到地图但我无法拖动地图但我可以点击另一个标记，因此，再次启动活动。
我复制了我的代码，看看是否有人可以解决这个问题：
-Map Fragment：
public class DondeFragment extends ListFragment implements OnMapClickListener, OnScrollListener,
OnCameraChangeListener, OnClickListener {
GlobalClass global;
public MainActivity main;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
rootView = inflater.inflate(R.layout.fragment_donde, container, false);
if (container != null) {
container.removeAllViews();
}
addMap();
return rootView;
}
public void addMap() {
// obtengo el mapa
global.mapa = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
// Move the camera instantly to my position with a zoom of 15.
LatLng miPosicion = new LatLng(main.obtLatitud, main.obtLongitud);
global.mapa.moveCamera(CameraUpdateFactory.newLatLngZoom(miPosicion , 17) );
// Zoom in, animating the camera.
global.mapa.animateCamera(CameraUpdateFactory.zoomTo(17), 2000, null);
global.mapa.setOnCameraChangeListener(this);
global.mapa.setOnMapClickListener(this);
}
@Override
public void onStart() {
super.onStart();
// handler to the list
if (mWasLoading) {
mWasLoading = false;
mIsLoading = true;
mHandler.postDelayed(mAddItemsRunnable, 1000);
}
}
@Override
public void onStop() {
super.onStop();
// handler to the list
mHandler.removeCallbacks(mAddItemsRunnable);
mWasLoading = mIsLoading;
mIsLoading = false;
ventana = ventana;
// destroy the map
Fragment f = getActivity().getSupportFragmentManager().findFragmentById(R.id.map);
if (f != null) {
getActivity().getSupportFragmentManager().beginTransaction().remove(f).commitAllowingStateLoss();
}
}
@Override
public void onMapClick(LatLng arg0) {
if (global.stateOnClickMap == 1) {
hideSlideUp();
String colorLocal = ((MainActivity) getActivity()).colorCategoriaBackup;
((MainActivity) getActivity()).markerUnselected(colorLocal);
((MainActivity) getActivity()).markerBackup = null;
Log.v("EY", "You clicked the map ");
}
}
public void hideSlideUp() {
RelativeLayout slideLayout;
slideLayout = (RelativeLayout) rootView.findViewById(R.id.sliding_up);
if (slideLayout.getVisibility() != View.GONE) {
slideLayout.setVisibility(View.GONE);
}
}
@Override
public void onCameraChange(CameraPosition arg0) {
// TODO Auto-generated method stub
((MainActivity) getActivity()).markerBackup = null;
hideSlideUp();
Log.v("ONCAMERACHANGE","CHANGE: ha cambiado la camara");
LatLng centerMap = global.mapa.getCameraPosition().target;
Log.v("Datos Mapa","CHANGE: Centro Mapa: " + centerMap);
VisibleRegion widthPoint = global.mapa.getProjection().getVisibleRegion();
Log.v("Datos Mapa","CHANGE: Visible: " + widthPoint);
LatLng topRight = widthPoint.latLngBounds.northeast;
LatLng bottonLeft = widthPoint.latLngBounds.southwest;
double lat1 = topRight.latitude;
double lon1 = topRight.longitude;
double lat2 = bottonLeft.latitude;
double lon2 = bottonLeft.longitude;
double R = 6378.137; // km
double dLat = Math.toRadians(lat2-lat1);
double dLon = Math.toRadians(lon2-lon1);
double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2)) *
Math.sin(dLon/2) * Math.sin(dLon/2);
double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
double d = R * c;
Log.v("Datos Mapa","CHANGE: Distancia total: " + d);
((MainActivity) getActivity()).addItemsToMap(d, centerMap);
}
}
