私は、GoogleMapsAPIとGooglePlacesAPIに関して次のチュートリアルを使用しています。

http://www.androidhive.info/2012/08/android-working-with-google-places-and-maps-tutorial/

とても良いです。近くの場所のマーカーを地図上に表示し、カテゴリごとに異なる種類のマーカーを表示することができました。ただし、ユーザーが私のマーカーの1つをクリックしたときに、アラートダイアログに施設の電話番号を表示したいと思います。このために、私は場所の詳細検索を使用しています。

以下に、問題が発生しているマップアクティビティコードのスニペットを示します。

//Map Activity OnCreate()
//Check for null nearPlaces
if(nearPlaces.results!=null)
{
    //Loop through all places
    for(Place place:nearPlaces.results)
    {

        latitude=place.geometry.location.lat;
        longitude=place.geometry.location.lng;
        placeRef=place.reference;

        new LoadDetails().execute(placeRef);

        for(String s:place.types)
        {
            if(s.contains("restaurant"))
            {
                Drawable rMarker=this.getResources().getDrawable(R.drawable.restaurant);

                //phone=lp.getPhone();
                iOverlay=new MyItemizedOverlay(rMarker,this);

                //GeoPoint to place on map
                gp=new GeoPoint((int)(latitude*1E6),(int)(longitude*1E6));

                //Map overlay item
                oItem=new OverlayItem(gp, place.name, place.vicinity+"\n"+"Rating: "+place.rating+" "+phone);

                iOverlay.addOVerlay(oItem);

                iOverlay.addOVerlay(oItem);
                mapOverlays.add(iOverlay);
            }

施設の電話番号になりたい可変文字列電話があります。

これは、AsyncTaskを拡張するLoadDetailsクラスです。

private class LoadDetails extends AsyncTask<String, String, String>
{
    @Override
    protected void onPostExecute(String result) {
                if(placeDetails!=null)
                {
                    if(placeDetails.status.equals("OK"))
                    {
                        if(placeDetails.result!=null)
                        {
                            phone=placeDetails.result.formatted_phone_number;
                            Log.d("Phone #'s",phone);
                        }
                    }
                }



    }

    @Override
    protected String doInBackground(String... params) {

        String reference=params[0];
        googlePlaces=new GooglePlaces();

        try{
            placeDetails=googlePlaces.getPlaceDetails(reference);
        }catch (Exception e){
            e.printStackTrace();
        }
        return null;
    }


}

OnPostExecuteでは、可変電話が設定され、LogCatにさまざまな場所の電話番号が表示されます。ただし、電話でマップアクティビティに移動し、レストランのマーカーをクリックすると、可変電話は常にnullになります。これを修正するにはどうすればよいですか？

どんな助けでも素晴らしいでしょう。

前もって感謝します。
