在模拟器中,我的 gps 代码工作正常。但是当我在设备中安装我的应用程序时,我无法获得当前的纬度和经度。
当我从模拟器发送 lat long 时,它会得到正确的 lat long,这是通过模拟器发送的。我不知道为什么不能在设备中工作?
我已经启用Option > Advance option > gps > gps servce
并将位置设置为 ON。是否有任何其他设置可以获取设备中的当前位置?
private boolean currentLocation() {
boolean retval = true;
try {
LocationProvider lp = LocationProvider.getInstance(null);
if (lp != null) {
lp.setLocationListener(new LocationListenerImpl(), interval, 1, 1);
} else {
// GPS is not supported, that sucks!
// Here you may want to use UiApplication.getUiApplication() and post a Dialog box saying that it does not work
retval = false;
}
} catch (LocationException e) {
System.out.println("Error: " + e.toString());
}
return retval;
}
private class LocationListenerImpl implements LocationListener {
public void locationUpdated(LocationProvider provider, Location location) {
if (location.isValid()) {
heading = location.getCourse();
longitude = location.getQualifiedCoordinates().getLongitude();
latitude = location.getQualifiedCoordinates().getLatitude();
altitude = location.getQualifiedCoordinates().getAltitude();
speed = location.getSpeed();
// This is to get the Number of Satellites
String NMEA_MIME = "application/X-jsr179-location-nmea";
satCountStr = location.getExtraInfo("satellites");
if (satCountStr == null) {
satCountStr = location.getExtraInfo(NMEA_MIME);
}
// this is to get the accuracy of the GPS Cords
QualifiedCoordinates qc = location.getQualifiedCoordinates();
accuracy = qc.getHorizontalAccuracy();
}
