我写的是带来了当前位置的代码，但它是不是给我的位置，因为它从来不打电话onLocationChanged()是有什么办法可以找到的位置。
mobileLocation为这个即将到来的情况下0，那么执行转到else块。
我的代码
public class FindLocation {
private LocationManager locManager;
private LocationListener locListener;
private Location mobileLocation;
private String provider;
public FindLocation(Context ctx){
locManager = (LocationManager) ctx.getSystemService(Context.LOCATION_SERVICE);
locListener = new LocationListener() {
@Override
public void onStatusChanged(String provider, int status,
Bundle extras) {
}
@Override
public void onProviderEnabled(String provider) {
}
@Override
public void onProviderDisabled(String provider) {
}
@Override
public void onLocationChanged(Location location) {
System.out.println("mobile location is in listener="+location);
mobileLocation = location;
}
};
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 1, locListener);
if (mobileLocation != null) {
locManager.removeUpdates(locListener);
String londitude = "Londitude: " + mobileLocation.getLongitude();
String latitude = "Latitude: " + mobileLocation.getLatitude();
String altitiude = "Altitiude: " + mobileLocation.getAltitude();
String accuracy = "Accuracy: " + mobileLocation.getAccuracy();
String time = "Time: " + mobileLocation.getTime();
Toast.makeText(ctx, "Latitude is = "+latitude +"Longitude is ="+londitude, Toast.LENGTH_LONG).show();
} else {
System.out.println("in find location 4");
Toast.makeText(ctx, "Sorry location is not determined", Toast.LENGTH_LONG).show();
}
}
}
你永远不会得到一个位置，或者仅作为您在您的评论写“有时它得到的位置，但没有点击的时间。”？
可能是你的代码比的LocationManager，这可能尚未被称为onLocationChanged（）更快。 更改您的代码，以获得最后已知的位置，或者等到locListener被称为：
locManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, 1000, 1, locListener);
mobileLocation = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (mobileLocation != null) {
我跑我在真机上的应用程序。 我使用网络，而不是GPS和onLocationChanged被称为：
locMan.requestSingleUpdate(LocationManager.NETWORK_PROVIDER, this, null);
我的事情你忘了许可

要么
声明适当的类象
public class MyLocationListener implements LocationListener {
@Override
public void onLocationChanged(Location arg0) {
latitude = arg0.getLatitude();
longitude = arg0.getLongitude();
}
}

public class AndroidLocationServices extends Service {

String MODULE="AndroidLocationServices",TAG="";
private LocationManager locationManager;
double getLattitude=0,getLogitude=0;
private static final long MIN_TIME_BW_UPDATES = 1; // 1 minute

wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "DoNotSleep");
// Toast.makeText(getApplicationContext(), "Service Created",

Log.e("Google", "Service Created");
}
@Override

//locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 2500, 0, listener);
locationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, listener);
}
public LocationListener listener = new LocationListener() {

};
@Override
public void onDestroy() {

super.onDestroy();
// wakeLock.release();
}
}
表现：
<service android:name=".services.AndroidLocationServices"/>
使用之前启动服务：
startService(new Intent(this, AndroidLocationServices.class));
后直接locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 1, locListener)中，添加以下代码：
locManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 1000, 1, locListener);
编辑：纠正代码要归功于@Fabian Streitel评论。
在我的情况下，应用程序是没有要求的权限。 虽然我已经添加在menifest文件的权限。 所以，我不能让我的应用程序来访问该位置。
作为一个解决方法，我手动去： Settings->Permissions->Your location并启用位置同意我欠开发应用程序。 这固定我的问题。
我认为只有当应用程序通过Android Studio中安装了此问题。 我希望当应用程序从谷歌播放安装就不会发生。
