如何在Google Maps V2的自定义InfoWindow中创建图片幻灯片-Android API

Question

I am a newbie wrt android development. My goal is to have a video running inside a customized info window in google maps V2 API android. I know how to make a video run inside a view (by loading series of images making them to look like a movie) Also I learnt how to load image inside a customized infowindow. I am trying to have image slide show inside the infowindow. But the problem is only the first image is getting loaded. Unless otherwise I click on the marker again, the infoWindow contents are not getting updated. I am attaching my code below

main_activity.java

public class BasicMapActivity extends FragmentActivity {
   private GoogleMap mMap;
   static final LatLng MELBOURNE = new LatLng(-37.81319, 37.00);
   public static LatLng argOut = null;
   public static String msg = "1";

   private static ImageView imageView;
   int i=0;
   int imgid[]={R.drawable.a,R.drawable.b,R.drawable.c,R.drawable.d};
   RefreshHandler refreshHandler=new RefreshHandler();

   class RefreshHandler extends Handler{
       @Override
       public void handleMessage(Message msg) {
        BasicMapActivity.this.updateUI(null);
       }
       public void sleep(long delayMillis){
           this.removeMessages(0);
           sendMessageDelayed(obtainMessage(0), delayMillis);
       }
   };

  public void updateUI(Marker markerShowingInfoWindow){
        refreshHandler.sleep(2000);
        if(i<imgid.length){
            imageView.setImageResource(imgid[i]);
            if (markerShowingInfoWindow != null && true) {
                markerShowingInfoWindow.showInfoWindow();
            } 
            i++;
          }
   }


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

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


private void setUpMapIfNeeded() {
    if (mMap == null) {
        mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                .getMap();
        if (mMap != null) {
            setUpMap();
        }
    }
}

private void setUpMap() {

    Marker melbourne = mMap.addMarker(new MarkerOptions()
    .position(MELBOURNE)
    .title("Melbourne")
    .snippet("Population: 4,137,400"));

   // when a infowindow is tapped (infowindow open request)
    mMap.setInfoWindowAdapter(new InfoWindowAdapter() {
        @Override
        public View getInfoWindow(Marker arg0) {
            return null;
        }

        @Override
        public View getInfoContents(Marker arg0) {
            String test = arg0.getTitle();
            View v = getLayoutInflater().inflate(R.layout.windowlayout, null);
            imageView = (ImageView) v.findViewById(R.id.imageView1);
            imageView.setVisibility(View.VISIBLE);
            if(!test.equalsIgnoreCase("Melbourne")){
                 updateUI(arg0);
            } else {
                imageView.setImageDrawable(getResources().getDrawable(R.drawable.badge_wa));
            }

            return v;
        }
    });

}

}

I am trying to call the showInfoWindow() on the marker object that is passed on to the updateUI function within the getInfoContents. What am i doing wrong and whats the correct way to call the showInfo window after the imageView inside the infoWindow gets a new image?

Answer 1

My goal is to have a video running inside a customized info window in google maps V2 API android

That is not possible, sorry. The map, including its info window, is rendered by another process (the one running the Play Services Framework). It cannot handle animation, let alone videos.

But the problem is only the first image is getting loaded.

Correct.

You are welcome to call showInfoWindow() again on the Marker , to trigger it to call your InfoWindowAdapter again, where you can show the next image in sequence, and see if that works to your satisfaction.

Answer 2

I was stuck on a similar problem I solved it by closing the infowindow and showing it again, Time between these two events doesn't even give off a flicker. I also added a Cache Array. I found this link very useful in solving my own issue Link

public View getInfoContents(Marker marker) {
    View popup = contentsCache.get(marker.getId()); // cache array


        if(popup == null){
                contentsCache.put(marker.getId(), popup);
                popup = mInflater.inflate(R.layout.custom_info_contents, null);
                TextView tv=(TextView)popup.findViewById(R.id.title);
                tv.setText(marker.getTitle());
                ImageView i = (ImageView) popup.findViewById(R.id.img);
                Uri image=images.get(marker.getId());
                Log.i(TAG, marker.getId()+"");
                if (image != null) {
                    Picasso.with(mContext).load(image).placeholder(R.drawable.ic_launcher).into(i, new MarkerCallback(marker));
                }
        }       

    return popup;
}

MarkerCallback.java

public class MarkerCallback implements Callback {
    Marker marker=null;

    MarkerCallback(Marker marker) {
      this.marker=marker;

    }

    @Override
    public void onError() {
      Log.e(getClass().getSimpleName(), "Error loading thumbnail!");
    }

    @Override
    public void onSuccess() {
      if (marker != null && marker.isInfoWindowShown()) {
        marker.hideInfoWindow();
        marker.showInfoWindow();
      }
    }
}
