动态显示信息窗口到GoogleMap的V2 [英] Show dynamically to InfoWindow Googlemap V2

问题描述

我正在开发一个旅游应用程序。在谷歌地图API V2的功能，我想每一个信息窗口有一个不同的图像。

I'm developing a travel app. On Google map API V2 feature, I want each InfoWindow have an different image.

我已经覆盖WindowInfoAdapter为自定义标题和细节文本。

I've override WindowInfoAdapter for custom title and detail text.

public class MyInfoWindowAdapter implements InfoWindowAdapter {
    private final View  mView;
    public MyInfoWindowAdapter(Activity activity) {
        mView = activity.getLayoutInflater().inflate(R.layout.custom_info_window, null);
    }
    @Override
    public View getInfoContents(Marker marker){
        String title = marker.getTitle();
        final String snippet = marker.getSnippet();
        final TextView titleUi = (TextView) mView.findViewById(R.id.title);
        // final View subtitleUi = mView.findViewById(R.id.subtitle);
        final TextView snippetUi = ((TextView) mView.findViewById(R.id.snippet));
        final TextView placeid = ((TextView) mView.findViewById(R.id.placeid));
        final RatingBar voteUi = ((RatingBar) mView.findViewById(R.id.ratingBar1));
        final ImageView imageUi = ((ImageView) mView.findViewById(R.id.imageView1));
        titleUi.setText(title);

        //other code
        return mView;
    }

    @Override
    public View getInfoWindow(Marker marker){
        return null;
    }
}

这正常工作，因为它是字符串。结果
现在我想使用的ImageView的InforWindow添加图像。结果
出现问题，因为我使用的图像来自断言和数据流。这件事情是这样

It work fine because It's String.
Now I want to add an image on that InforWindow using ImageView.
The problem appear because I used image from asserts and stream. It's something like this

InputStream ims = getSherlockActivity().getAssets().open("images/" + imageSubPath + "/" + splitedImages[i].toLowerCase());
Drawable iImages = Drawable.createFromStream(ims, null);

我不能把可绘制对象片段，因为我之前做过的字符串。
我想在这里的结果：

I can't put Drawable object to snippet as I did with String before. The result I want here:

我怎样才能在信息窗口显示图像，任何意见都很大！

How can I display images on InfoWindows, any advices are great!

推荐答案

您需要创建额外的数据结构来保存您的图像，例如：

You would have to create additional data structure to hold your images, e.g.:

Map<Marker, Drawable> allMarkersMap = new HashMap<Marker, Drawable>();

在您添加标记的GoogleMap ：

allMarkersMap.put(marker, iImages);

在 getInfoContents ：

Drawable iImages = allMarkersMap.get(marker);

和它添加到的ImageView 。

另一种方法是使用 Android地图扩展，其中有像方法Marker.setData（对象）和对象Marker.getData（）。这个你可以用它来直接分配可绘制来标记，就像你做的片段。

Another way would be to use Android Maps Extensions, which has methods like Marker.setData(Object) and Object Marker.getData(). This you can use to directly assign Drawable to marker, just like you do with snippet.
