android - onInfoWindowClick 方法在 android 中不起作用

Question

我创建了一个在 map 中显示我当前位置的应用程序。我想在 onInfoWindowClick 方法下的 toast 消息中显示位置。但是 toast 不起作用。在此先感谢您的帮助!

这是我的代码:

public  class SearchProviderLocation extends Activity implements LocationListener,OnInfoWindowClickListener   {

class MyInfoWindowAdapter implements InfoWindowAdapter{

    private final View myContentsView;

    MyInfoWindowAdapter(){
        myContentsView = getLayoutInflater().inflate(R.layout.custom_info_contents, null);
    }

    @Override
    public View getInfoContents(Marker marker) {

        TextView tvTitle = ((TextView)myContentsView.findViewById(R.id.title));
        tvTitle.setText(marker.getTitle());
        TextView tvSnippet = ((TextView)myContentsView.findViewById(R.id.snippet));
        tvSnippet.setText(marker.getSnippet());

        return myContentsView;
    }

    @Override
    public View getInfoWindow(Marker marker) {
        // TODO Auto-generated method stub
        return null;
    }

}


final int RQS_GooglePlayServices = 1;
TextView tvLocInfo;
GoogleMap map;
private LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
String provider;
double latitude;
protected double longitude; 
protected boolean gps_enabled,network_enabled;

private String val,val1;
private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters
private static final long MINIMUM_TIME_BETWEEN_UPDATES = 1000; // in Milliseconds

boolean isGPSEnabled ;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_search_provider_location);


    try {

        LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
           lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);
               map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
                .getMap();

               map.setInfoWindowAdapter(new MyInfoWindowAdapter());

         }      

    catch (Exception e) {
            e.printStackTrace();
                        }
}


@Override
public void onLocationChanged(Location location) {
    // TODO Auto-generated method stub

    map.clear();

    Geocoder geo = new Geocoder(this.getApplicationContext(), Locale.getDefault());
  try {
        List<Address> addresses = geo.getFromLocation(location.getLatitude(), location.getLongitude(), 1);

        MarkerOptions mp = new MarkerOptions();

           mp.position(new LatLng(location.getLatitude(), location.getLongitude()));
           mp.icon(BitmapDescriptorFactory.fromResource(R.drawable.marker));

           mp.snippet("Address:"+" "+" "+addresses.get(0).getFeatureName()+" "+addresses.get(0).getAdminArea()+" "+addresses.get(0).getLocality()+" "+addresses.get(0).getPostalCode()+""+addresses.get(0).getCountryCode());
           mp.title(addresses.get(0).getLocality()+", "+addresses.get(0).getCountryName());

           map.addMarker(mp);
           map.animateCamera(CameraUpdateFactory.newLatLngZoom(
            new LatLng(location.getLatitude(), location.getLongitude()), 14)); 
  } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

@Override
protected void onResume() {
    super.onResume();

    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());

    if (resultCode == ConnectionResult.SUCCESS){
        Toast.makeText(getApplicationContext(), 
                "GooglePlayServicesAvailable", 
                Toast.LENGTH_LONG).show();
    }else{
        GooglePlayServicesUtil.getErrorDialog(resultCode, this, RQS_GooglePlayServices);    
    }
}

public void onMapLongClick(LatLng point) {
    tvLocInfo.setText("New marker added@" + point.toString());

    Marker newMarker = map.addMarker(new MarkerOptions()
                                .position(point)
                                .snippet(point.toString()));
    newMarker.setTitle(newMarker.getId());

}
@Override
public void onInfoWindowClick(Marker marker)
{
   marker.getTitle();
   final String ssid = marker.getTitle(); 

   Toast.makeText(getBaseContext(),"You click @" + ssid,Toast.LENGTH_SHORT).show();

}

@Override
public void onProviderDisabled(String provider) {

}

@Override
public void onProviderEnabled(String provider) {


}                   

@Override
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
    // TODO Auto-generated method stub

}}

尝试下面的代码:

map.setOnInfoWindowClickListener(new OnInfoWindowClickListener()
{
    @Override public void onInfoWindowClick(Marker arg0) {
        final String ssid = arg0.getTitle(); 
        Toast.makeText(SearchProviderLocation.this,"You click @" + ssid,Toast.LENGTH_SHORT).show();
    }
});
