내 문제는 특정 위치에 PushPin이있는 Google지도를 표시하지만 내 애플리케이션에서 압정을 클릭하면 위치 이름이 토스트 또는 텍스트보기에 표시되지만 어떻게해야할지 모르겠다. 이것을하기 위해?Google MapOverlay 문제

도와주세요. 다음

내 코드입니다 : -

Map_Activity.java:-

public class Map_Activity extends MapActivity { 

    String mArea; 
    MapView mapView; 
    MapController mc; 
    GeoPoint p; 
    String[] mLongitude,mLatitude,mAreaArray; 
    double lat,lng; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.google_map_screen); 

     Bundle bdl=getIntent().getExtras(); 
     mArea= bdl.getString("Area Name"); 

     mAreaArray=getResources().getStringArray(R.array.PlaceName); 
     mLongitude=getResources().getStringArray(R.array.Longitude); 
     mLatitude=getResources().getStringArray(R.array.Latitude); 

     for(int i=0;i<mAreaArray.length;i++){ 
      if(mArea.equals(mAreaArray[i])){ 
       lat=Float.valueOf(mLatitude[i]); 
       lng=Float.valueOf(mLongitude[i]); 
      } 
     } 

     mapView = (MapView) findViewById(R.id.googlemap); 
     LinearLayout zoomLayout = (LinearLayout) findViewById(R.id.zoom); 
     @SuppressWarnings("deprecation") 
     View zoomView = mapView.getZoomControls(); 

     zoomLayout.addView(zoomView, new LinearLayout.LayoutParams(
       LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); 
     mapView.displayZoomControls(true); 

     mc = mapView.getController(); 

     p = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6)); 

     mc.animateTo(p); 
     mc.setZoom(17); 
     MapOverlay mapOverlay = new MapOverlay(); 
     List<Overlay> listOfOverlays = mapView.getOverlays(); 
     listOfOverlays.clear(); 
     listOfOverlays.add(mapOverlay); 
     mapView.invalidate(); 

    } 

    @Override 
    protected boolean isRouteDisplayed() { 
     // TODO Auto-generated method stub 
     return false; 
    } 

    public boolean onKeyDown(int keyCode, KeyEvent event) { 
     MapController mc = mapView.getController(); 
     switch (keyCode) { 
     case KeyEvent.KEYCODE_3: 
      mc.zoomIn(); 
      break; 
     case KeyEvent.KEYCODE_1: 
      mc.zoomOut(); 
      break; 
     } 
     return super.onKeyDown(keyCode, event); 
    } 

    class MapOverlay extends com.google.android.maps.Overlay { 
     @Override 
     public boolean draw(Canvas canvas, MapView mapView, boolean shadow, 
       long when) { 
      super.draw(canvas, mapView, shadow); 

      // ---translate the GeoPoint to screen pixels--- 
      Point screenPts = new Point(); 
      mapView.getProjection().toPixels(p, screenPts); 

      // ---add the marker--- 
      Bitmap bmp = BitmapFactory.decodeResource(getResources(), 
        R.drawable.pushpin); 
      canvas.drawBitmap(bmp, screenPts.x, screenPts.y - 50, null); 
      return true; 
     } 

     @Override 
     public boolean onTap(GeoPoint p, MapView mapView) { 
      // TODO Auto-generated method stub 
      Toast.makeText(Google_Map_Activity.this, "Sorry Don't Click", Toast.LENGTH_SHORT).show(); 
      return super.onTap(p, mapView); 
     } 
    } 
}
