我對我的android應用程序有點麻煩。我想使用手機的GPS顯示當前的經緯度。我能夠獲得手機的當前座標,但它顯示爲一個雙倍數值...我認爲小數點後6-8位。有沒有辦法減少小數點後的位數?有沒有辦法減少小數點後的位數?
這裏是我的代碼:
public class Localisation extends Activity implements LocationListener{
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
private String TripDescription;
private String tripID;
TextView txtLat;
String lat;
String provider;
protected String latitude, longitude;
protected boolean gps_enabled, network_enabled;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_localisation);
txtLat = (TextView) findViewById(R.id.textView1);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
@Override
public void onLocationChanged(Location location) {
txtLat = (TextView) findViewById(R.id.textView1);
txtLat.setText("Latitude:" + location.getLatitude() + ", Longitude:" + location.getLongitude());
}
@Override
public void onProviderDisabled(String arg0) {
Log.d("Latitude","disable");
}
@Override
public void onProviderEnabled(String provider) {
Log.d("Latitude","enable");
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("Latitude","status");
}
考慮我的答案upvote,這是正確的。 – AlexWien
