#Lon=116486291,Lat=39899332,Speed=0,Alt=65,Direction=0# Android地图和定位学习总结 首届 Google 暑期大学生博客分享大赛——2010 Android 篇 android.location包下有这么一些接口和类： Interfaces GpsStatus.Listener GpsStatus.NmeaListener LocationListener Classes Address Criteria Geocoder GpsSatellite GpsStatus Location LocationManager LocationProvider com.google.android.maps包下有这些类： All Classes GeoPoint ItemizedOverlay ItemizedOverlay.OnFocusChangeListener MapActivity MapController MapView MapView.LayoutParams MapView.ReticleDrawMode MyLocationOverlay Overlay Overlay.Snappable OverlayItem Projection TrackballGestureDetector 我们边看代码边熟悉这些类。 要获取当前位置坐标，就是从Location对象中获取latitude和longitude属性。那Location对象是如何创建的？ LocationManager locMan=(LocationManager)getSystemService(Context.LOCATION_SERVICE);//LocationManager对象只能这么创建，不能用new Locationlocation=locMan.getLastKnownLocation(LocationManager.GPS_PROVIDER);if(location==null){ location=locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);} //注意要为应用程序添加使用权限 自然是获取最新的地理位置信息，那LocationManager.GPS_PROVIDER和LocationManager.NETWORK_PROVIDER有什么区别呢？俺也不是学通信的，对这个不了解，在网上看到有人想“在室外有GPS定位，在室内想用Wifi或基站定位”。 除了直接使用LocationManager提供的静态Provider（如GPS_PROVIDER和NETWORK_PROVIDER等）外，还可以使用我们自己创建的LocationProvider对象。创建LocationProvider对象一般要先创建Criteria对象，来设置我们的LocationProvider要满足什么样的标准 Criteria myCri=new Criteria();myCri.setAccuracy(Criteria.ACCURACY_FINE);//精确度 myCri.setAltitudeRequired(false);//海拔不需要 myCri.setBearingRequired(false);//Bearing是“轴承”的意思，此处可理解为地轴线之类的东西，总之Bearing Information是一种地理位置信息的描述 myCri.setCostAllowed(true);//允许产生现金消费 myCri.setPowerRequirement(Criteria.POWER_LOW);//耗电 String myProvider=locMan.getBestProvider(myCri,true);public String getBestProvider(Criteria criteria, boolean enabledOnly)Returns the name of the provider that best meets the given criteria.Only providers that are permitted to be accessed by the calling activity will be returned.If several providers meet the criteria, the one with the best accuracy is returned.If no provider meets the criteria, the criteria are loosened in the following sequence: power requirement accuracy bearing speed altitude Note that the requirement on monetary cost is not removed in this process.Parameters criteria the criteria that need to be matched enabledOnly if true then only a provider that is currently enabled is returned Returns name of the provider that best matches the requirements only翻译为“最适合的“ Location location=locMan.getLastKnownLoation(myProvider);double latitude=location.getLatitude();//获取纬度 double longitude=location.getLongitude();//获取经度 我想知道当前位置描述（比如“武汉华中科技大学”而不是一个经纬值）呢？这就要使用GeoCoder创建一个Address对象了。 Geocoder gc=new Geocoder(context,Locale.CHINA);//Locale是java.util中的一个类 List getFromLocation(double latitude, double longitude, int maxResults)Returns an array of Addresses that are known to describe the area immediately surrounding the given latitude and longitude.(返回给定经纬值附近的一个Address）既然是“附近”那实际编码时我们没必要把经纬值给的那么精确，而取一个近似的整数，像这样： /*自经纬度取得地址，可能有多行地址*/ List Address address=listAddress.get(0); for(int i=0;i sb.append(address.getAddressLine(i)).append(”n“); } sb.append(address.getLocality()).append(”n“); sb.append(address.getPostalCode()).append(”n“); sb.append(address.getCountryName()).append(”n“);} public int getMaxAddressLineIndex() Since: API Level 1 Returns the largest index currently in use to specify an address line.If no address lines are specified,-1 is returned.public String getAddressLine(int index) Since: API Level 1 Returns a line of the address numbered by the given index(starting at 0), or null if no such line is present.String getCountryName()Returns the localized country name of the address, for example ”Iceland“, or null if it is unknown.String getLocality()Returns the locality of the address, for example ”Mountain View“, or null if it is unknown.反过来我们可以输入地址信息获取经纬值 Geocoder mygeoCoder=new Geocoder(myClass.this,Locale.getDefault());List //strAddress是输入的地址信息 if(!lstAddress.isEmpty()){ Address address=lstAddress.get(0); double latitude=address.getLatitude()*1E6; double longitude=adress.getLongitude()*1E6; GeoPoint geopoint=new GeoPoint((int)latitude,(int)longitude);} A class for handling geocoding and reverse geocoding.Geocoding is the process of transforming a street address or other description of a location into a(latitude, longitude)coordinate.Public Constructors Geocoder(Context context, Locale locale)Constructs a Geocoder whose responses will be localized for the given Locale.Geocoder(Context context)Constructs a Geocoder whose responses will be localized for the default system Locale.public List Since: API Level 1 getFromLocationName(String locationName, int Returns an array of Addresses that are known to describe the named location, which may be a place name such as ”Dalvik, Iceland“, an address such as ”1600 Amphitheatre Parkway, Mountain View, CA“, an airport code such as ”SFO", etc..The returned addresses will be localized for the locale provided to this class's constructor.The query will block and returned values will be obtained by means of a network lookup.The results are a best guess and are not guaranteed to be meaningful or correct.It may be useful to call this method from a thread separate from your primary UI thread.Parameters locationName maxResults Returns a user-supplied description of a location max number of results to return.Smaller numbers(1 to 5)are recommended a list of Address objects.Returns null or empty list if no matches were found or service available.there is no backend Throws IllegalArgumentException IOException 说了半天还只是个定位，地图还没出来。下面要用到com.google.android.maps包了 下面的代码我们让地图移到指定点 GeoPoint p=new GeoPoint((int)(latitude*1E6),(int)(longitude*1E6));MapView mapview=(MapView)findViewById(R.id.mv);MapController mapContr=mapview.getController();mapview.displayZoomControls(true);//显示地图缩放的按钮 mapContr.animateTo(p);//带动画移到p点 mapContr.setZoom(7);setZoom public int setZoom(int zoomLevel)Sets the zoomlevel of the map.The value will be clamped to be between 1 and 21 inclusive, though not all areas have tiles at higher zoom levels.This just sets the level of the zoom directly;for a step-by-step zoom with fancy interstitial animations, use if locationName is null if the network is unavailable or any other I/O problem occurs zoomIn()or zoomOut().Parameters: zoomLevelThe Canvas upon which to draw.Note that this may already have a transformation applied, so be sure to leave it the way you found it.mapViewIf true, draw the shadow layer.If false, draw the overlay contents.public boolean draw(android.graphics.Canvas canvas, MapView mapView, boolean shadow, long when)when-The timestamp of the draw.Draw call for animated overlays.By default, calls through to draw(Canvas, MapView, boolean)and returns false.Canvas公共方法 void drawBitmap(Bitmap bitmap, Rect src, Rect dst, Paint paint) Draw the specified bitmap, scaling/translating automatically to fill the destination rectangle.第二篇：Android地图和定位学习总结
