第1步:
在高德开放平台添加应用,添加新Key,获取Key值;
第2步:
下载高德地图SDK、高德定位SDK,将其中的jar包添加到Android Studio工程下的libs目录下,并添加与当前应用的依赖关系;
第3步:
在AndroidManifest.xml文件中添加地图和定位使用的相关权限;
<!--//地图包、搜索包需要的基础权限-->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!--//定位包、导航包需要的额外权限(注:基础权限也需要)-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<!--用于进行网络定位-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!--用于访问GPS定位-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!--获取运营商信息,用于支持提供运营商信息相关的接口-->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<!--用于访问wifi网络信息,wifi信息会用于进行网络定位-->
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<!--这个权限用于获取wifi的获取权限,wifi信息会用来进行网络定位-->
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<!--用于访问网络,网络定位需要上网-->
<uses-permission android:name="android.permission.INTERNET" />
<!--用于读取手机当前的状态-->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<!--写入扩展存储,向扩展卡写入数据,用于写入缓存定位数据-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
第4步:
添加应用中定位用到的服务
<!--添加服务-->
<service android:name="com.amap.api.location.APSService"/>
第5步:
在应用中配置相关的Key值
<meta-data
android:name="com.amap.api.v2.apikey"
android:value="此处填写你申请的Key值" />第6步: 1)在对应的布局文件中 添加MapView控件 2)代码实现 public class DingWei extends AppCompatActivity implements LocationSource, AMapLocationListener {
private TextView currentText;
private static final int WRITE_COARSE_LOCATION_REQUEST_CODE = 100;
private MapView mapView = null;
//AMap是地图对象
private AMap aMap;
//声明AMapLocationClient类对象,定位发起端
private AMapLocationClient mLocationClient = null;
//声明mLocationOption对象,定位参数
private AMapLocationClientOption mLocationOption = null;
//声明mListener对象,定位监听器
private 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 double lat;
private double lon;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ding_wei);
//6.0定位权限
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
//申请WRITE_EXTERNAL_STORAGE权限
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION},
WRITE_COARSE_LOCATION_REQUEST_CODE);//自定义的code
}
//获取地图引用控件
mapView = (MapView) findViewById(R.id.map_dingwei);
currentText= (TextView) findViewById(R.id.current_text);
//在activity执行onCreate时执行mapView.onCreate(savedInstanceState),实现生命周期管理
mapView.onCreate(savedInstanceState);
if (aMap == null) {
aMap = mapView.getMap();
//设置显示定位按钮,并且可以点击
UiSettings uiSettings = aMap.getUiSettings();
//设置了定位的监听,这里要实现LocationSource接口
aMap.setLocationSource(this);
//设置是否显示定位按钮
uiSettings.setMyLocationButtonEnabled(true);
//显示定位层并且可以出发定位,默认是false
aMap.setMyLocationEnabled(true);
}
//开始定位
location();
}
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
//可在此继续其他操作。
}
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);
//设置是否定位定位一次,默认为false
mLocationOption.setOnceLocation(false);
//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2000ms
mLocationOption.setInterval(2000);
//给定位客户端对象设置定位参数
mLocationClient.setLocationOption(mLocationOption);
//启动定位
mLocationClient.startLocation();
}
@Override

//在activity执行onDestory时执行mapView.onDestory(),实现地图生命周期管理
mapView.onDestroy();
