我正在按照教程來獲取我的當前位置。我寫了教程所說的內容,但我只是不明白我的經驗。我正在使用無線連接。我試過了:
geo fix -77.036519 38.896143
仍然沒有獲得緯度/經度。我的代碼如下;當前位置在Android模擬器中不工作
import java.util.List;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationManager;
import android.location.LocationListener;
import android.os.Bundle;
import android.widget.TextView;
public class TestProviderController extends Activity {
LocationManager locationManager;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String location_context=Context.LOCATION_SERVICE;
locationManager=(LocationManager)getSystemService(location_context);
testProvider();
}
public void testProvider(){
TextView tv = (TextView)findViewById(R.id.myTextView);
StringBuilder sb = new StringBuilder("Enabled Providers:");
List<String> providers = locationManager.getProviders(true);
for (String provider : providers) {
locationManager.requestLocationUpdates(provider, 1000, 0,
new LocationListener() {
public void onLocationChanged(Location location) {}
public void onProviderDisabled(String provider){}
public void onProviderEnabled(String provider){}
public void onStatusChanged(String provider, int status,
Bundle extras){}
});
sb.append("\n").append(provider).append(":");
Location location = locationManager.getLastKnownLocation(provider);
if (location != null) {
double lat = location.getLatitude();
double lng = location.getLongitude();
sb.append(lat).append(",").append(lng);
} else {
sb.append("No Location");
}
}
tv.setText(sb);
}
}
任何人都可以幫忙解決問題嗎?
