我与安普森号的位置有关。
我尝试了以下法典:
LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location loc = getLastKnownLocation(LocationManager.GPS_PROVIDER);
什么是错的?

在您的<代码>AndroidManifest.xml文档中,您是否登记了一位现场听众?
LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location loc = getLastKnownLocation(LocationManager.GPS_PROVIDER);
lm.requestLocationUpdates(LocationManager.GPS, 100, 1, locationListener);
然后有完成您任务的方法,即<代码>。
private final LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
latitude = location.getLatitude();
longitude = location.getLongitude();
}
我的问题与你一样,我总是收到一片废地物体,但最后是容易解决。 您必须有一个有效的全球定位系统定位,因此,如果全球定位系统无法运行,而且你有足够的信号,定位物体将等于ALWAYS。
您是否在安妮斯·曼尼费斯颁发许可证? 您需要这些许可才能进入用户地点申请:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" />
这里,你可以使用:
LocationManager lm = (LocationManager) mContext.getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
String bestProvider = lm.getBestProvider(criteria, false);
Location loc = lm.getLastKnownLocation(bestProvider);
last_lat = loc.getLatitude();
last_lng = loc.getLongitude();
你们需要ParaManger这样的案例:
初审:
LocationManager lm = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
Wrong:
Location loc = getLastKnownLocation(LocationManager.GPS_PROVIDER);
更正:
Location loc = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
