获取当前地理位置和经纬度实例：

1、实现定位监听接口

implements AMapLocationListener {

2、创建获取地理位置实例

  //声明AMapLocationClient类对象，定位发起端private AMapLocationClient mLocationClient = null;//声明mLocationOption对象，定位参数public AMapLocationClientOption mLocationOption = null;//声明mListener对象，定位监听器private LocationSource.OnLocationChangedListener mListener = null;//标识，用于判断是否只显示一次定位信息和用户重新定位private boolean isFirstLoc = true;private void location() {//初始化定位mLocationClient = new AMapLocationClient(getApplicationContext());//设置定位回调监听mLocationClient.setLocationListener(this);//初始化定位参数mLocationOption = new AMapLocationClientOption();//设置定位模式为Hight_Accuracy高精度模式，Battery_Saving为低功耗模式，Device_Sensors是仅设备模式mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);//设置是否返回地址信息（默认返回地址信息）mLocationOption.setNeedAddress(true);//设置是否只定位一次,默认为falsemLocationOption.setOnceLocation(false);//设置是否强制刷新WIFI，默认为强制刷新mLocationOption.setWifiActiveScan(true);//设置是否允许模拟位置,默认为false，不允许模拟位置mLocationOption.setMockEnable(false);//设置定位间隔,单位毫秒,默认为2000msmLocationOption.setInterval(30000);//给定位客户端对象设置定位参数mLocationClient.setLocationOption(mLocationOption);//启动定位mLocationClient.startLocation();}@Overridepublic void onLocationChanged(AMapLocation aMapLocation) {if (aMapLocation != null) {if (aMapLocation.getErrorCode() == 0) {//定位成功回调信息，设置相关消息aMapLocation.getLocationType();//获取当前定位结果来源，如网络定位结果，详见官方定位类型表aMapLocation.getLatitude();//获取纬度aMapLocation.getLongitude();//获取经度aMapLocation.getAccuracy();//获取精度信息SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");Date date = new Date(aMapLocation.getTime());df.format(date);//定位时间aMapLocation.getAddress();//地址，如果option中设置isNeedAddress为false，则没有此结果，网络定位结果中会有地址信息，GPS定位不返回地址信息。aMapLocation.getCountry();//国家信息aMapLocation.getProvince();//省信息aMapLocation.getCity();//城市信息aMapLocation.getDistrict();//城区信息aMapLocation.getStreet();//街道信息aMapLocation.getStreetNum();//街道门牌号信息aMapLocation.getCityCode();//城市编码aMapLocation.getAdCode();//地区编码// 如果不设置标志位，此时再拖动地图时，它会不断将地图移动到当前的位置if (isFirstLoc) {//点击定位按钮 能够将地图的中心移动到定位点
//                    mListener.onLocationChanged(aMapLocation);//添加图钉//  aMap.addMarker(getMarkerOptions(amapLocation));//获取定位信息StringBuffer buffer = new StringBuffer();buffer.append(aMapLocation.getCountry() + ""+ aMapLocation.getProvince() + ""+ aMapLocation.getCity() + ""+ aMapLocation.getProvince() + ""+ aMapLocation.getDistrict() + ""+ aMapLocation.getStreet() + ""+ aMapLocation.getStreetNum());addrlg = aMapLocation.getAddress();startlo =String.valueOf(aMapLocation.getLongitude()) ;dstartla = aMapLocation.getLatitude();dstartlo = aMapLocation.getLongitude();Log.i("lgq","谷歌等等-======"+dstartla+"......"+dstartlo);ShareUtil.sharedPstring("nowla", String.valueOf(dstartla));ShareUtil.sharedPstring("nowlo", String.valueOf(dstartlo));ShareUtil.sharedPstring("nowad", addrlg);isFirstLoc = false;}} else {//显示错误信息ErrCode是错误码，errInfo是错误信息，详见错误码表。Log.e("lgqAmapError", "location Error, ErrCode:"+ aMapLocation.getErrorCode() + ", errInfo:"+ aMapLocation.getErrorInfo());Toast.makeText(getApplicationContext(), "定位失败", Toast.LENGTH_LONG).show();}}}

3、执行

location();

设置显示中心位置，比例

aMap.moveCamera(CameraUpdateFactory.changeLatLng(latLonPoint));//中心显示位置

aMap.moveCamera(CameraUpdateFactory.zoomTo(17));//比例

aMap.setMyLocationEnabled(true);// 设置为true表示启动显示定位蓝点，false表示隐藏定位蓝点并不进行定位，默认是false。

if (mMap != null && mLocation != null) {CameraUpdate newLatLngZoom = CameraUpdateFactory.newLatLngZoom(new LatLng(mLocation.getLatitude(), mLocation.getLongitude()), bili);mMap.moveCamera(newLatLngZoom);
}

地图刷新位置监听

     aMap.setOnCameraChangeListener(new AMap.OnCameraChangeListener() {@Overridepublic void onCameraChange(CameraPosition cameraPosition) {}@Overridepublic void onCameraChangeFinish(CameraPosition cameraPosition) {
//                addMarkerInScreenCenter();LatLng target = cameraPosition.target;LgqLog.e("刷新数据-=======");int ifyou = ShareUtil.getSharedInt("youss");if (ifyou==0){regeocodeSearch(target.latitude, target.longitude, 3000);}}});
