1、配置app获取位置信息权限
1、配置app获取位置信息权限
<!-- 允许程序访问CellID或WiFi热点来获取粗略的位置 -->
<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"/>
2、获取经纬度工具类
public class LocationUtil {
public static void getCurrentLocation(Context context, LocationCallBack locationCallBack) {
if (locationCallBack == null) {
return;
}
if (context == null) {
locationCallBack.onFail("请确保传入的参数context不为null");
}
//如果系统版本号在23及其以上则检查权限
if (Build.VERSION.SDK_INT >= 23 &&
ContextCompat.checkSelfPermission(context, Manifest.permission_group.LOCATION) == PackageManager.PERMISSION_GRANTED) {
locationCallBack.onFail("请确保已经获取定位权限");
}
//获取LocationManager对象
LocationManager locationM = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
//实例化MyLocationListener
MyLocationListener locationListener = new MyLocationListener(locationM, locationCallBack);
//配置Criteria耗电低
Criteria cri = new Criteria();
cri.setPowerRequirement(Criteria.POWER_LOW);
// 获取可用的provider,第二个参数标识 provider是否可用.
String bestProvider = locationM.getBestProvider(cri, true);
if (!TextUtils.isEmpty(bestProvider)) {
LogUtil.e("bestProvider = " + bestProvider + "可用");
locationM.requestLocationUpdates(bestProvider, 0, 0, locationListener);
} else if (locationM.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
LogUtil.e(LocationManager.NETWORK_PROVIDER + "可用");
locationM.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
} else if (locationM.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
LogUtil.e(LocationManager.GPS_PROVIDER + "可用");
locationM.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
} else {
//定位不可用,提示打开GPS
LogUtil.e("定位不可用,提示打开GPS");
locationCallBack.onFail("无可用的定位方式,请打开GPS");
}
}
/**
* LocationListener 的实现类
*/
private static class MyLocationListener implements LocationListener {
private LocationManager mLocationManager;
private LocationCallBack mLocationCallBack;
public MyLocationListener(LocationManager locationManager, LocationCallBack locationCallBack) {
this.mLocationManager = locationManager;
this.mLocationCallBack = locationCallBack;
}
@Override
public void onLocationChanged(Location location) {
if (location != null) {
if (mLocationCallBack != null) {
mLocationCallBack.onSuccess(location);
}
if (mLocationManager != null) {
mLocationManager.removeUpdates(this);
}
} else {
if (mLocationCallBack != null) {
mLocationCallBack.onFail("location == null");
}
}
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
}
/**
* 定位结果回调
*/
public interface LocationCallBack {
/**
* 定位成功
*
* @param location
*/
void onSuccess(Location location);
/**
* 定位失败
*
* @param msg
*/
void onFail(String msg);
}
}
3、根据经纬度获取位置信息工具类
/**
* 根据经纬度获取地址信息
*/
public class GetAddressUtil {
Context context;
public GetAddressUtil(Context context) {
this.context = context;
}
public String getAddress(double lnt, double lat) {
Geocoder geocoder = new Geocoder(context);
boolean falg = geocoder.isPresent();
LogUtil.e("the falg is " + falg);
StringBuilder stringBuilder = new StringBuilder();
try {
//根据经纬度获取地理位置信息---这里会获取最近的几组地址信息,具体几组由最后一个参数决定
List<Address> addresses = geocoder.getFromLocation(lat, lnt, 1);
if (addresses.size() > 0) {
Address address = addresses.get(0);
for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
//每一组地址里面还会有许多地址。这里我取的前2个地址。xxx街道-xxx位置
if (i == 0) {
stringBuilder.append(address.getAddressLine(i)).append("-");
}
if (i == 1) {
stringBuilder.append(address.getAddressLine(i));
break;
}
}
stringBuilder.append(address.getCountryName()).append("_");//国家
stringBuilder.append(address.getFeatureName()).append("_");//周边地址
stringBuilder.append(address.getLocality()).append("_");//市
// stringBuilder.append(address.getPostalCode()).append("_");
// stringBuilder.append(address.getCountryCode()).append("_");//国家编码
// stringBuilder.append(address.getAdminArea()).append("_");//省份
// stringBuilder.append(address.getSubAdminArea()).append("_");
// stringBuilder.append(address.getThoroughfare()).append("_");//道路
// stringBuilder.append(address.getSubLocality()).append("_");//香洲区
// stringBuilder.append(address.getLatitude()).append("_");//经度
// stringBuilder.append(address.getLongitude());//维度
Log.d("thistt", "地址信息--->" + stringBuilder);
}
} catch (Exception e) {
LogUtil.d("获取经纬度地址异常");
e.printStackTrace();
}
return stringBuilder.toString();
}
}
4、使用
LocationUtil.getCurrentLocation(this, object : LocationUtil.LocationCallBack {
override fun onSuccess(location: Location) {
val s = GetAddressUtil(this@MainActivity).getAddress(
location.longitude,
location.latitude
)
LogUtil.e(s)
}
override fun onFail(msg: String) {
LogUtil.e(msg)
}
})
