基本配置，依赖lib，配置权限，配置key等这些这里就不做介绍了
1.首先在布局xml文件中添加地图控件:
<com.amap.api.maps.MapViewandroid:id="@+id/map"android:layout_width="match_parent"android:layout_height="match_parent"/>
2.简述地图生命周期的管理：
public class MainActivity extends Activity {MapView mMapView = null;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState); setContentView(R.layout.activity_main);//获取地图控件引用mMapView = (MapView) findViewById(R.id.map);//在activity执行onCreate时执行mMapView.onCreate(savedInstanceState)，创建地图mMapView.onCreate(savedInstanceState);}@Overrideprotected void onDestroy() {super.onDestroy();//在activity执行onDestroy时执行mMapView.onDestroy()，销毁地图mMapView.onDestroy();}@Overrideprotected void onResume() {super.onResume();//在activity执行onResume时执行mMapView.onResume ()，重新绘制加载地图mMapView.onResume();}@Overrideprotected void onPause() {super.onPause();//在activity执行onPause时执行mMapView.onPause ()，暂停地图的绘制mMapView.onPause();}@Overrideprotected void onSaveInstanceState(Bundle outState) {super.onSaveInstanceState(outState);//在activity执行onSaveInstanceState时执行mMapView.onSaveInstanceState (outState)，保存地图当前的状态mMapView.onSaveInstanceState(outState);} }
3.显示地图
//定义了一个地图viewmapView = (MapView) findViewById(R.id.map);mapView.onCreate(savedInstanceState);// 此方法须覆写，虚拟机需要在很多情况下保存地图绘制的当前状态。//初始化地图控制器对象AMap aMap;if (aMap == null) {aMap = mapView.getMap(); }
下面一个案例
效果图如下：
下面是代码
MainActivity
public class MainActivity extends AppCompatActivity implements LocationSource, AMapLocationListener {MapView mMapView = null;//初始化地图控制器对象AMap aMap;//定位需要的数据LocationSource.OnLocationChangedListener mListener;AMapLocationClient mlocationClient;AMapLocationClientOption mLocationOption;//定位蓝点MyLocationStyle myLocationStyle;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//获取地图控件引用mMapView = (MapView) findViewById(R.id.map);//在activity执行onCreate时执行mMapView.onCreate(savedInstanceState)，创建地图mMapView.onCreate(savedInstanceState);if (aMap == null) {aMap = mMapView.getMap();}//设置地图的放缩级别aMap.moveCamera(CameraUpdateFactory.zoomTo(12));// 设置定位监听aMap.setLocationSource(this);// 设置为true表示显示定位层并可触发定位，false表示隐藏定位层并不可触发定位，默认是falseaMap.setMyLocationEnabled(true);// 设置定位的类型为定位模式，有定位、跟随或地图根据面向方向旋转几种aMap.setMyLocationType(AMap.LOCATION_TYPE_LOCATE);//蓝点初始化myLocationStyle = new MyLocationStyle();//初始化定位蓝点样式类myLocationStyle.myLocationType(MyLocationStyle.LOCATION_TYPE_LOCATION_ROTATE);//连续定位、且将视角移动到地图中心点，定位点依照设备方向旋转，并且会跟随设备移动。（1秒1次定位）如果不设置myLocationType，默认也会执行此种模式。myLocationStyle.interval(2000); //设置连续定位模式下的定位间隔，只在连续定位模式下生效，单次定位模式下不会生效。单位为毫秒。aMap.setMyLocationStyle(myLocationStyle);//设置定位蓝点的Style//aMap.getUiSettings().setMyLocationButtonEnabled(true);设置默认定位按钮是否显示，非必需设置。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。myLocationStyle.myLocationType(MyLocationStyle.LOCATION_TYPE_LOCATION_ROTATE);//连续定位、且将视角移动到地图中心点，定位点依照设备方向旋转，并且会跟随设备移动。（1秒1次定位）默认执行此种模式。myLocationStyle.showMyLocation(true);aMap.setOnMyLocationChangeListener(new AMap.OnMyLocationChangeListener() {@Overridepublic void onMyLocationChange(Location location) {//从location对象中获取经纬度信息，地址描述信息，建议拿到位置之后调用逆地理编码接口获取}});}@Overrideprotected void onResume() {super.onResume();//在activity执行onResume时执行mMapView.onResume ()，重新绘制加载地图mMapView.onResume();}@Overrideprotected void onPause() {super.onPause();//在activity执行onPause时执行mMapView.onPause ()，暂停地图的绘制mMapView.onPause();}@Overrideprotected void onSaveInstanceState(Bundle outState) {super.onSaveInstanceState(outState);//在activity执行onSaveInstanceState时执行mMapView.onSaveInstanceState (outState)，保存地图当前的状态mMapView.onSaveInstanceState(outState);}//--定位监听---------/*** 激活定位*/@Overridepublic void activate(OnLocationChangedListener onLocationChangedListener) {mListener = onLocationChangedListener;if (mlocationClient == null) {//初始化定位mlocationClient = new AMapLocationClient(this);//初始化定位参数mLocationOption = new AMapLocationClientOption();//设置定位回调监听mlocationClient.setLocationListener(this);//设置为高精度定位模式mLocationOption.setLocationMode(AMapLocationClientOption.AMapLocationMode.Hight_Accuracy);//设置定位参数mlocationClient.setLocationOption(mLocationOption);// 此方法为每隔固定时间会发起一次定位请求，为了减少电量消耗或网络流量消耗，// 注意设置合适的定位时间的间隔（最小间隔支持为2000ms），并且在合适时间调用stopLocation()方法来取消定位请求// 在定位结束后，在合适的生命周期调用onDestroy()方法// 在单次定位情况下，定位无论成功与否，都无需调用stopLocation()方法移除请求，定位sdk内部会移除mlocationClient.startLocation();//启动定位}}/*** 停止定位*/@Overridepublic void deactivate() {mListener = null;if (mlocationClient != null) {mlocationClient.stopLocation();mlocationClient.onDestroy();}mlocationClient = null;}//定位回调 在回调方法中调用“mListener.onLocationChanged(amapLocation);”可以在地图上显示系统小蓝点。@Overridepublic void onLocationChanged(AMapLocation aMapLocation) {if (mListener != null && aMapLocation != null) {if (aMapLocation != null && aMapLocation.getErrorCode() == 0) {mListener.onLocationChanged(aMapLocation);// 显示系统小蓝点} else {String errText = "定位失败," + aMapLocation.getErrorCode() + ": " + aMapLocation.getErrorInfo();Log.e("定位AmapErr", errText);}}}@Overrideprotected void onDestroy() {super.onDestroy();//在activity执行onDestroy时执行mMapView.onDestroy()，销毁地图mMapView.onDestroy();if (null != mlocationClient) {mlocationClient.onDestroy();}}}
activity_main

显示小蓝点可以根据自己想要的去做更改详情可以看官方的文档：/api/android-sdk/guide/create-map/mylocation
