Ich arbeite in einer Android App. Der Benutzer sucht in Google Maps nach Restaurants. In der Google-Karte werden Markierungen für das gesamte Restaurant seines Nachbarn angezeigt. Wenn er auf eine Markierung tippt, wird ein benutzerdefiniertes InfoWindow angezeigt. Mein Problem ist, dass ich das von Google Places zurückgegebene Bild nicht laden kann. Ich bekomme die URL des Bildes richtig, aber ich kann es nicht im Fenster anzeigen.

InfoWindow

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@color/bg_color" >

<ImageView
        android:id="@+id/place_icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:focusable="false"" />

<TextView
    android:id="@+id/place_title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<TextView
    android:id="@+id/place_vicinity"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

<LinearLayout 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:background="@color/bg_color" >

    <RatingBar
         android:id="@+id/place_rating"
         style="?android:attr/ratingBarStyleSmall"
         android:numStars="5"
         android:rating="0"
         android:isIndicator="false"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="5dip" />

    <ImageView
        android:id="@+id/navigate_icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:focusable="false"
        android:src="@drawable/navigate" />

</LinearLayout>

Beim Erstellen habe ich dies

mGoogleMap.setInfoWindowAdapter(new InfoWindowAdapter() {

            // Use default InfoWindow frame
            @Override
            public View getInfoWindow(Marker arg0) {
                return null;
            }

            // Defines the contents of the InfoWindow
            @Override
            public View getInfoContents(Marker arg0) {

                // Getting view from the layout file info_window_layout
                View v = getLayoutInflater().inflate(R.layout.info_window_layout, null);

                // Getting the snippet from the marker
                String snippet = arg0.getSnippet();

                // Getting the snippet from the marker
                String titlestr = arg0.getTitle();

                String cutchar1= "%#";
                String cutchar2= "%##";
                String ratingstr = snippet.substring(0,snippet.indexOf( cutchar1 ));
                String vicinitystr = snippet.substring(snippet.indexOf( cutchar1 )+2, snippet.indexOf( cutchar2 ) );
                String iconurl= snippet.substring(snippet.indexOf( cutchar2 )+3);

                // Getting reference to the TextView to set latitude
                TextView title = (TextView) v.findViewById(R.id.place_title);

                TextView vicinity = (TextView) v.findViewById(R.id.place_vicinity);

                ImageView image = (ImageView) v.findViewById(R.id.navigate_icon);

                // Setting the latitude
                title.setText(titlestr);

                // declare RatingBar object
                RatingBar rating=(RatingBar) v.findViewById(R.id.place_rating);// create RatingBar object
                if( !(ratingstr.equals("null")) ){
                    rating.setRating(Float.parseFloat(ratingstr));
                }
                vicinity.setText(vicinitystr);                  

                final DownloadImageTask download = new DownloadImageTask((ImageView) v.findViewById(R.id.place_icon) ,arg0);
                download.execute(iconurl);
                // Returning the view containing InfoWindow contents
                return v;

            }

});

und der DownloadImage-Code lautet:

private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
      ImageView bmImage;
      Marker marker;
      boolean refresh;

      public DownloadImageTask(final ImageView bmImage, final Marker marker) {
          this.bmImage = bmImage;
          this.marker=marker;
          this.refresh=false;
      }

     public void SetRefresh(boolean refresh ){
         this.refresh=true;

     }

    /*  @Override
      protected void onPreExecute() 
      {
          super.onPreExecute();
          bmImage.setImageBitmap(null);
      }*/

      @Override
      protected Bitmap doInBackground(String... urls) {
          String urldisplay = urls[0];
          Bitmap mIcon11 = null;
          try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
          } catch (Exception e) {
              Log.e("Error", e.getMessage());
              e.printStackTrace();
          }
          return mIcon11;
      }
      @Override
      protected void onPostExecute(Bitmap result) {
          if(!refresh){
              SetRefresh(refresh);
              bmImage.setImageBitmap(result);
              marker.showInfoWindow();
          }
      }
    }

Wenn ich den Code ausführe und auf die Markierung tippe, wird die Ausführung von getInfoContents nicht unterbrochen und das Symbol wird nicht angezeigt.

Warum ist das passiert?
