Android TextView setText superposiciones anterior Texto

Me gustaría establecer un texto en un TextView de mi aplicación (lication). Este es el código que usé:

TextView lonTextView = (TextView) findViewById(R.id.textViewLonWert); lonTextView.setText(longitude.toString()); 

En realidad funciona, pero el texto anterior todavía se muestra! Por ejemplo, un 4 superpone un 8 (no se puede leer el texto más).

Tengo una Actividad iniciando un servicio. A continuación, registrar un LocalBroadcastReceiver en la actividad. El servicio periódicamente envía objetos de ubicación a la actividad. Desde la ubicación me sale por ejemplo la longitud y me gustaría actualizar un textview (sólo contiene la longitud) con la nueva longitud.

Yo estaría muy contento si alguien tiene una idea para resolver este problema.

ACTUALIZACIÓN: El código completo es bastante largo, así que aquí están los fragmentos relevantes:

TrackingActivity.java

 public class TrackingActivity extends Activity { // GPSTracker class GPSTracker gps; public String filename; /* Um eigene Position anzuzeigen */ ArrayList<OverlayItem> overlayItemArray; protected MapView mapView; protected MapController mapController; public Boolean isPause; public Boolean isTracking; public MyLocationOverlay myLocationOverlay; PathOverlay myPath; List<GeoPoint> path; public BroadcastReceiver screenReceiver; /* Textviews setzen */ TextView lonTextView; TextView latTextView; TextView altTextView; TextView accTextView; // Initiating Menu XML file (menu.xml) /*@Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater menuInflater = getMenuInflater(); menuInflater.inflate(R.menu.menu_tracking, menu); MenuItem mi_startTracking = menu.findItem(R.id.start_tracking); mi_startTracking.setVisible(true); return true; }*/ /** * Event Handling for Individual menu item selected * Identify single menu item by it's id * */ @Override public boolean onOptionsItemSelected(MenuItem item) { ... } @Override public boolean onPrepareOptionsMenu(Menu menu) { ... } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_tracking); isTracking = false; isPause = false; // create GPS-class object gps = new GPSTracker(TrackingActivity.this ,null); myPath = new PathOverlay(Color.RED, this); path = new ArrayList<GeoPoint>(); /* Map anzeigen */ mapView = new MapView(this, 500); mapView.setTileSource(TileSourceFactory.MAPNIK); org.osmdroid.views.MapView.LayoutParams mapParams = new org.osmdroid.views.MapView.LayoutParams( org.osmdroid.views.MapView.LayoutParams.MATCH_PARENT, org.osmdroid.views.MapView.LayoutParams.MATCH_PARENT, null, 0, 0, 0); /*löst Fehler aus: mapView.setClickable(true);*/ mapView.setBuiltInZoomControls(true); mapController = new MapController(mapView); mapView.getController().setZoom(15); //--- Create Overlay overlayItemArray = new ArrayList<OverlayItem>(); DefaultResourceProxyImpl defaultResourceProxyImpl = new DefaultResourceProxyImpl(this); MyItemizedIconOverlay myItemizedIconOverlay = new MyItemizedIconOverlay( overlayItemArray, null, defaultResourceProxyImpl); mapView.getOverlays().add(myItemizedIconOverlay); //--- //Add current position myLocationOverlay = new MyLocationOverlay(this, mapView); mapView.getOverlays().add(myLocationOverlay); /* Lege Pfad auf Karte */ mapView.getOverlays().add(myPath); mapView.invalidate(); LinearLayout myLayout = (LinearLayout) findViewById(R.id.trackingLinearLayoutMap); myLayout.addView(mapView,mapParams); } private BroadcastReceiver gpsDataReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { //Log.d("TrackingActivity", "in Receiver"); /* alles was der Service liefert */ String action = intent.getAction(); Double altitude = intent.getDoubleExtra("altitude", 0); Double longitude = intent.getDoubleExtra("longitude", 0); Double latitude = intent.getDoubleExtra("latitude", 0); Bundle b = intent.getExtras(); Location location = (Location)b.get("location"); Log.d("received","Receiver: "+longitude+" ; "+latitude); //Log.d("TrackingActivity", "vor GeoPoint"); GeoPoint locGeoPoint = new GeoPoint(latitude, longitude); /* Erstelle Pfad */ if(isTracking){ path.add(locGeoPoint); myPath.addPoint(locGeoPoint); } //Log.d("TrackingActivity", "nach GeoPoint: "+locGeoPoint.toString()); mapController.setCenter(locGeoPoint); setOverlayLoc(location); /* Textviews Werte setzen */ lonTextView = (TextView) findViewById(R.id.textViewLonWert); lonTextView.setText(longitude.toString()); //lonTextView.invalidate(); latTextView = (TextView) findViewById(R.id.textViewLatWert); latTextView.setText(latitude.toString()); //latTextView.invalidate(); altTextView = (TextView) findViewById(R.id.textViewAltWert); altTextView.setText(altitude.toString()); //altTextView.invalidate(); accTextView = (TextView) findViewById(R.id.textViewAccWert); accTextView.setText(Float.toString(location.getAccuracy())+" m"); //accTextView.invalidate(); /* Karte aktualisieren */ mapView.invalidate(); } }; ... @Override protected void onResume() { super.onResume(); /* Registriere BroadcastReceiver für GPSDaten */ LocalBroadcastManager.getInstance(this).registerReceiver(gpsDataReceiver, new IntentFilter("gpsdata")); ... } ... 

Aquí mi diseño .xml:

¡Espero eso ayude!
