百度地图v3.5最新版本使用覆盖物，通用版。

好久没用百度地图了。以前用的是2.4.0，现在更新到3.5了，发现很多接口用不了，或者重构了。为此写了一份比较通用的项目。

如果下载后项目运行有误，可以评论私聊。

1.单个添加覆盖物 MapActivity主要代码

public class MapAvtivity extends FragmentActivity{

private MyMapFragment map;

@Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
setContentView(R.layout.my_map);
FragmentManager fm = getSupportFragmentManager();
PUser user = new PUser();
user.setLatitude(25.856013);
user.setLongitude(114.958339);
map = MyMapFragment.newInstance(user);
if (fm.findFragmentById(R.id.fragment) == null) {
fm.beginTransaction().add(R.id.fragment, map).commit();
}
}

public static class MyMapFragment extends MFragment<PUser> implements OnMarkerClickListener{

public static MyMapFragment newInstance(PUser user) {
MyMapFragment f = new MyMapFragment();
Bundle args = new Bundle();
args.putParcelable("user", user);
f.setArguments(args);
return f;
}

private PUser user;
private Marker mMarkerA;
private InfoWindow mInfoWindow;

@Override
public void onCreate(Bundle arg0) {
super.onCreate(arg0);

}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);

user = getArguments().getParcelable("user");

LatLng llA = new LatLng(user.getLatitude(), user.getLongitude());
BitmapDescriptor bdA = BitmapDescriptorFactory
.fromResource(R.drawable.ic_launcher);
OverlayOptions over = new MarkerOptions().position(llA).icon(bdA)
.zIndex(9).draggable(true);

mBaiduMap.addOverlay(over);
mBaiduMap.setOnMarkerClickListener(this);
mMarkerA = (Marker) mBaiduMap.addOverlay(over);

}

@Override
public Loader<PUser> onCreateLoader(int id, Bundle args) {
return null;
}

@Override
public boolean onMarkerClick(final Marker marker) {
Button button = new Button(getActivity());
button.setBackgroundResource(R.drawable.popup);
OnInfoWindowClickListener listener = null;
if (marker == mMarkerA) {
button.setText("更改位置");
listener = new OnInfoWindowClickListener() {
public void onInfoWindowClick() {
LatLng ll = marker.getPosition();
LatLng llNew = new LatLng(ll.latitude + 0.005,
ll.longitude + 0.005);
marker.setPosition(llNew);
mBaiduMap.hideInfoWindow();
}
};
LatLng ll = marker.getPosition();
mInfoWindow = new InfoWindow(BitmapDescriptorFactory.fromView(button), ll, -47, listener);
mBaiduMap.showInfoWindow(mInfoWindow);
}
return true;
}
}

}

2.基类MFragment是继承Fragment的，至于为什么不继承SupportMapFragment是为了更好的在一般项目中通用。

有了以下个类就可以实现定位自己的位置，并添加单个覆盖物。上代码在说：

public abstract class MFragment<T> extends Fragment implements LoaderCallbacks<T>, OnMapClickListener{

protected BaiduMap mBaiduMap;
protected MapView mapView;
public MyLocationListenner myListener = new MyLocationListenner();
private LocationClient mLocClient;

private boolean isFirstLoc = true;

@Override
public void onCreate(Bundle arg0) {
super.onCreate(arg0);

getLoaderManager().initLoader(1, null, this);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle arg2) {
View v = inflater.inflate(R.layout.map, container, false);
mapView = (MapView) v.findViewById(R.id.map);
mBaiduMap = mapView.getMap();
mBaiduMap.setMyLocationEnabled(true);
MapStatusUpdate msu = MapStatusUpdateFactory.zoomTo(16.0f);
mBaiduMap.setMapStatus(msu);
mBaiduMap.setOnMapClickListener(this);
mBaiduMap.setMaxAndMinZoomLevel(3, 20);
mLocClient = new LocationClient(getActivity());
mLocClient.registerLocationListener(myListener);
LocationClientOption option = new LocationClientOption();
option.setOpenGps(true);
option.setCoorType("bd09ll");
option.setScanSpan(1000);
mLocClient.setLocOption(option);
mLocClient.start();

return v;
}

public void forceLoad() {
getLoaderManager().restartLoader(1, null, this);
}

public class MyLocationListenner implements BDLocationListener {

@Override
public void onReceiveLocation(BDLocation location) {
if (location == null || mapView == null)
return;
MyLocationData locData = new MyLocationData.Builder()
.accuracy(location.getRadius())
.direction(100).latitude(location.getLatitude())
.longitude(location.getLongitude()).build();
mBaiduMap.setMyLocationData(locData);
if (isFirstLoc) {
isFirstLoc = false;
LatLng ll = new LatLng(location.getLatitude(),
location.getLongitude());
MapStatusUpdate u = MapStatusUpdateFactory.newLatLng(ll);
mBaiduMap.animateMapStatus(u);
}
}

public void onReceivePoi(BDLocation poiLocation) {
}
}

@Override
public void onStart() {
super.onStart();

}

@Override
public void onResume() {
super.onResume();
}

@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
}

@Override
public void onPause() {
super.onPause();
}

@Override
public void onStop() {
super.onStop();
}

@Override
public void onDestroy() {
super.onDestroy();
//		mBaiduMap.setMyLocationEnabled(false);
//		mapView.onDestroy();
//		mapView = null;
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
}

@Override
abstract public Loader<T> onCreateLoader(int id, Bundle args);

@Override
public void onLoadFinished(Loader<T> loader, T data) {
}

@Override
public void onLoaderReset(Loader<T> loader) {

}

@Override
public void onMapClick(LatLng arg0) {

}

@Override
public boolean onMapPoiClick(MapPoi arg0) {
String title = "";
if (arg0 != null){
title = arg0.getName();
Toast.makeText(getActivity(), title, Toast.LENGTH_SHORT).show();
}
return false;
}

}

3.很多情况下不需要添加覆盖物，只需要定位。这里写了一个定位的Service.

public class BaiduLocationService extends Service {

public static final String ACTION_LOCATION_CHANGED = "com.yundi.wlqc.service.action.location_changed";
private static final String TAG = "BaiduLocationService";
public boolean isAutoStopSelf;
public LocationClient mLocationClient;
public MyocationListenner myListener = new MyocationListenner();
private SDKReceiver mReceiver;

public void onCreate() {
super.onCreate();
SDKInitializer.initialize(getApplicationContext());
mLocationClient = new LocationClient(getApplicationContext());
mLocationClient.registerLocationListener(myListener);
IntentFilter iFilter = new IntentFilter();
iFilter.addAction(SDKInitializer.SDK_BROADTCAST_ACTION_STRING_PERMISSION_CHECK_ERROR);
iFilter.addAction(SDKInitializer.SDK_BROADCAST_ACTION_STRING_NETWORK_ERROR);
mReceiver = new SDKReceiver();
registerReceiver(mReceiver, iFilter);
}

public int onStartCommand(Intent intent, int flags, int startId) {
if(!mLocationClient.isStarted()) {
Log.d("BaiduLocationService", "Start locate");
LocationClientOption option = getLocationOption();
mLocationClient.setLocOption(option);
mLocationClient.requestLocation();
mLocationClient.start();
} else {
Log.d("BaiduLocationService", "Request locate");
mLocationClient.requestLocation();
}
if(intent != null) {
isAutoStopSelf = intent.getBooleanExtra("extra_stop", true);
}
return 0x1;
}

private LocationClientOption getLocationOption() {
LocationClientOption option = new LocationClientOption();
option.setOpenGps(true);
option.setCoorType("bd09ll");
option.setAddrType("all");
option.setScanSpan(1000);
option.setIsNeedAddress(true);
return option;
}

public void onDestroy() {
super.onDestroy();
Log.d("BaiduLocationService", "Stop locate");
mLocationClient.stop();
}

public IBinder onBind(Intent intent) {
return null;
}

public class MyocationListenner implements BDLocationListener {

public void onReceivePoi(BDLocation poiLocation) {
}

@Override
public void onReceiveLocation(BDLocation location) {
StringBuffer sb = new StringBuffer(256);
if (location.getLocType() == BDLocation.TypeGpsLocation) {
sb.append("GPS");
} else if (location.getLocType() == BDLocation.TypeNetWorkLocation) {
sb.append("Network");
}

sb.append("\nlatitude : ");
sb.append(location.getLatitude());
sb.append("\nlontitude : ");
sb.append(location.getLongitude());
sb.append("\naddr : ");
sb.append(location.getAddrStr());

Log.i(TAG, sb.toString());
System.out.println(sb.toString());
Toast.makeText(getApplicationContext(), sb.toString(), Toast.LENGTH_SHORT).show();

writeLocationAndSendBroadcast(location);

if (isAutoStopSelf) {
stopSelf();
}
}

}

private void writeLocationAndSendBroadcast(BDLocation bdlocation) {
Location location = new Location("local");
location.setLatitude(bdlocation.getLatitude());
location.setLongitude(bdlocation.getLongitude());
LocalBroadcastManager lbm = LocalBroadcastManager.getInstance(this);
Intent intent = new Intent("com.yundi.wlqc.service.action.location_changed");
intent.putExtra("extra_location", location);
intent.putExtra("exra_radius", bdlocation.getRadius());
//        intent.putExtra("extra_derect", bdlocation.getDerect());
lbm.sendBroadcast(intent);
}

private Context getService() {
return this;
}

public class SDKReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (action.equals(SDKInitializer.SDK_BROADTCAST_ACTION_STRING_PERMISSION_CHECK_ERROR)) {
Toast.makeText(getService(), "key error", Toast.LENGTH_SHORT)
.show();
}
if (action.equals(SDKInitializer.SDK_BROADCAST_ACTION_STRING_NETWORK_ERROR)) {
Toast.makeText(getService(), "network...", Toast.LENGTH_SHORT)
.show();
}
}
}
}

4.重点来了，需要添加一个列表呢？多个覆盖物呢？以下代码来：

public class MapListAvtivity extends FragmentActivity{

private MyMapFragment map;

@Override
protected void onCreate(Bundle arg0) {
super.onCreate(arg0);
setContentView(R.layout.my_map);
FragmentManager fm = getSupportFragmentManager();
map = MyMapFragment.newInstance();
if (fm.findFragmentById(R.id.fragment) == null) {
fm.beginTransaction().add(R.id.fragment, map).commit();
}
}

public static class MyMapFragment extends MListFragment<PUser> implements OnMarkerClickListener{

public static MyMapFragment newInstance() {
MyMapFragment f = new MyMapFragment();
return f;
}

@Override
protected List<PUser> loadData(Context context) throws Exception {
List<PUser> list = new ArrayList<PUser>();
PUser user = new PUser();
user.setId("1");
user.setLatitude(25.856013);
user.setLongitude(114.958339);
list.add(user);
PUser user1 = new PUser();
user1.setId("2");
user1.setLatitude(25.8444676614);
user1.setLongitude(114.908875473);
list.add(user1);
PUser user2 = new PUser();
user2.setId("3");
user2.setLatitude(25.830770050254);
user2.setLongitude(114.9804583851);
list.add(user2);
return list;
}

@Override
protected OverlayOptions getOverlayItem(PUser item) {
View v = View.inflate(getActivity(), R.layout.mdwd_map_item, null);
TextView t_name = (TextView) v.findViewById(R.id.t_name);
t_name.setText(item.getLatitude()+ "");
//            BitmapDrawable b = new BitmapDrawable(getResources(),
//                    ViewUtils.getBitmapFromView(v));
LatLng l = new LatLng(item.getLatitude(), item.getLongitude());
BitmapDescriptor bdA = BitmapDescriptorFactory.fromView(v);
Bundle b = new Bundle();
b.putParcelable("user", item);
OverlayOptions o = new MarkerOptions().position(l).
icon(bdA).zIndex(9).draggable(true).extraInfo(b);
mBaiduMap.setOnMarkerClickListener(this);
return o;
}

@Override
public boolean onMarkerClick(Marker arg0) {
for(Marker m : markers){
if(arg0 == m){
PUser user = arg0.getExtraInfo().getParcelable("user");
Toast.makeText(getActivity(), user.getId(), Toast.LENGTH_SHORT).show();
}
}
return true;
}

}

}

和MListFragment

public abstract class MListFragment<T> extends MFragment<List<T>> {

private Exception ex;
private OverlayManager overlayManager;
protected List<OverlayOptions> overlayOptions;
protected List<Marker> markers;

@Override
public Loader<List<T>> onCreateLoader(int id, Bundle args) {
return new ListAsyncTaskLoader<T>(getActivity()) {

@Override
protected List<T> loadInBackground(Context context) {
try {
return loadData(context);
} catch (Exception e) {
e.printStackTrace();
ex = e;
}
return null;
}

};
}

@Override
public void onLoadFinished(Loader<List<T>> loader, List<T> data) {
super.onLoadFinished(loader, data);
if (ex != null) {
ex = null;
return;
}

overlayOptions = new ArrayList<OverlayOptions>();
markers = new ArrayList<Marker>();
for (int i = 0; i < data.size(); i++) {
OverlayOptions item = getOverlayItem(data.get(i));
overlayOptions.add(item);
Marker m = (Marker) mBaiduMap.addOverlay(item);
markers.add(m);
}

}

abstract protected List<T> loadData(Context context) throws Exception;

abstract protected OverlayOptions getOverlayItem(T item);

public List<OverlayOptions> getOverlayOptions() {
return overlayOptions;
}

public void setOverlayOptions(List<OverlayOptions> overlayOptions) {
this.overlayOptions = overlayOptions;
}

}

5.此小demo里的MFragment, MListFragment在一般项目中很通用，需要的XML和LoaderCallbacks，有需要的话可以下载项目。
