LocationListener Classes Address Criteria Geocoder GpsSatellite GpsStatus Location LocationManager LocationProvider com.google.android.maps包下有這些類： All Classes GeoPoint ItemizedOverlay ItemizedOverlay.OnFocusChangeListener MapActivity MapController MapView MapView.LayoutParams MapView.ReticleDrawMode MyLocationOverlay Overlay Overlay.Snappable OverlayItem Projection TrackballGestureDetector 我們邊看代碼邊熟悉這些類。 要獲取當前位置坐標，就是從Location對象中獲取latitude和longitude屬性。那Location對象是如何創建的？ LocationManager locMan=(LocationManager)getSystemService(Context.LOCATION_SERVICE);//LocationManager對象只能這么創建，不能用new Locationlocation=locMan.getLastKnownLocation(LocationManager.GPS_PROVIDER);if(location==null){ location=locMan.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);} //注意要為應用程序添加使用權限 自然是獲取最新的地理位置信息，那LocationManager.GPS_PROVIDER和LocationManager.NETWORK_PROVIDER有什么區別呢？俺也不是學通信的，對這個不了解，在網上看到有人想“在室外有GPS定位，在室內想用Wifi或基站定位”。 除了直接使用LocationManager提供的靜態Provider（如GPS_PROVIDER和NETWORK_PROVIDER等）外，還可以使用我們自己創建的LocationProvider對象。創建LocationProvider對象一般要先創建Criteria對象，來設置我們的LocationProvider要滿足什么樣的標準 Criteria myCri=new Criteria();myCri.setAccuracy(Criteria.ACCURACY_FINE);//精確度 myCri.setAltitudeRequired(false);//海拔不需要 myCri.setBearingRequired(false);//Bearing是“軸承”的意思，此處可理解為地軸線之類的東西，總之Bearing Information是一種地理位置信息的描述 myCri.setCostAllowed(true);//允許產生現金消費 myCri.setPowerRequirement(Criteria.POWER_LOW);//耗電 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翻譯為“最適合的“ Location location=locMan.getLastKnownLoation(myProvider);double latitude=location.getLatitude();//獲取緯度 double longitude=location.getLongitude();//獲取經度 我想知道當前位置描述（比如“武漢華中科技大學”而不是一個經緯值）呢？這就要使用GeoCoder創建一個Address對象了。 Geocoder gc=new Geocoder(context,Locale.CHINA);//Locale是java.util中的一個類 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.(返回給定經緯值附近的一個Address）既然是“附近”那實際編碼時我們沒必要把經緯值給的那么精確，而取一個近似的整數，像這樣： /*自經緯度取得地址，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.反過來我們可以輸入地址信息獲取經緯值 Geocoder mygeoCoder=new Geocoder(myClass.this,Locale.getDefault());List //strAddress是輸入的地址信息 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 說了半天還只是個定位，地圖還沒出來。下面要用到com.google.android.maps包了 下面的代碼我們讓地圖移到指定點 GeoPoint p=new GeoPoint((int)(latitude*1E6),(int)(longitude*1E6));MapView mapview=(MapView)findViewById(R.id.mv);MapController mapContr=mapview.getController();mapview.displayZoomControls(true);//顯示地圖縮放的按鈕 mapContr.animateTo(p);//帶動畫移到p點 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地圖和定位學習總結
