图像未加载到使用 UiL 的谷歌地图标记中

我正在使用universal-image-loader-1.9.5.jar .我正在尝试在标记上显示用户图像。但是图像未显示。

我做了什么.

UIL 初始化

imageLoader = ImageLoader.getInstance();
        defaultOptions = new DisplayImageOptions.Builder()
        .showImageOnLoading(R.drawable.profile_image) // resource or drawable
        .showImageForEmptyUri(R.drawable.profile_image) // resource or drawable
        .showImageOnFail(R.drawable.profile_image) // resource or drawable
        .resetViewBeforeLoading(false)  // default
        .delayBeforeLoading(1000)
        .cacheInMemory(false) // default
        .cacheOnDisk(false) // default
        .considerExifParams(false) // default
        .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2) // default
        .bitmapConfig(Bitmap.Config.ARGB_8888) // default
        .displayer(new SimpleBitmapDisplayer()) // default
        .handler(new Handler()) // default
        .build();

File cacheDir = StorageUtils.getCacheDirectory(this);
config = new ImageLoaderConfiguration.Builder(this)
.memoryCacheExtraOptions(480, 800) // default = device screen dimensions
.diskCacheExtraOptions(480, 800, null)
.threadPoolSize(3) // default
.threadPriority(Thread.NORM_PRIORITY - 2) // default
.tasksProcessingOrder(QueueProcessingType.FIFO) // default
.denyCacheImageMultipleSizesInMemory()
.memoryCache(new LruMemoryCache(2 * 1024 * 1024))
.memoryCacheSize(2 * 1024 * 1024)
.memoryCacheSizePercentage(13) // default
.diskCache(new UnlimitedDiskCache(cacheDir)) // default
.diskCacheSize(50 * 1024 * 1024)
.diskCacheFileCount(100)
.diskCacheFileNameGenerator(new HashCodeFileNameGenerator()) // default
.defaultDisplayImageOptions(DisplayImageOptions.createSimple()) // default
.writeDebugLogs()
.build();
imageLoader.init(config);

使用 InfoWindowAdapter

googleMap.setInfoWindowAdapter(new MyCustomAdapterForItems());
public class MyCustomAdapterForItems implements InfoWindowAdapter {
    private final View myContentsView;
    MyCustomAdapterForItems() {
        myContentsView = mainFragmentActivity.getLayoutInflater().inflate(
                R.layout.map_info_window_dialog, null);
    }
    @Override
    public View getInfoContents(Marker marker) {
        return null;
    }
    @Override
    public View getInfoWindow(Marker marker) {
        try {
            JSONObject jsonMarker = new JSONObject(marker.getSnippet());
            String name = jsonMarker.getString("name");
            double distance = jsonMarker.getDouble("distance");
            String imagePath = jsonMarker.getString("profile_pic_address");
            String gender = jsonMarker.getString("gender");
            String birthDate = jsonMarker.getString("birthdate");
            age = hiApplication.getAge(birthDate);
            TextView tvName = ((TextView) myContentsView
                    .findViewById(R.id.tvMapChatName));
            TextView tvAge = ((TextView) myContentsView
                    .findViewById(R.id.tvMapChatAge));
            TextView tvDistance = ((TextView) myContentsView
                    .findViewById(R.id.distance));
            TextView tvGender = (TextView) myContentsView.findViewById(R.id.tvChatGender);
            RoundedImageView  image = (RoundedImageView) myContentsView.findViewById(R.id.profile_pic);
            imageLoader.displayImage(imagePath, image , defaultOptions , simpleLoader); //Image loading here
            tvName.setText(name);
            if(age == 0 ) tvAge.setText("");
            else tvAge.setText(age+"");
            tvGender.setText(gender);
            tvDistance.setText(new DecimalFormat("##.##").format(distance)+ " km.");
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return myContentsView;
    }
}

图像加载侦听器

private class SimpleLoader implements ImageLoadingListener {
        @Override
        public void onLoadingCancelled(String arg0, View arg1) {
            Log.d("d", "image cancelled");
        }
        @Override
        public void onLoadingComplete(String arg0, View view, Bitmap bitmap) {
            Log.d("d", "loading complete");
            ImageView imageView = (ImageView) view;
            imageView.setImageBitmap(bitmap);
        }
        @Override
        public void onLoadingFailed(String arg0, View arg1, FailReason arg2) {
            Log.d("d", "image loading failed");
        }
        @Override
        public void onLoadingStarted(String arg0, View arg1) {
            Log.d("d", "image loading started");
        }
    }

虽然我的日志显示图像已完全加载.这是我的日志.

01-21 02:38:13.561: D/d(7832): image loading started
01-21 02:38:13.567: D/ImageLoader(7832): Delay 1000 ms before loading...  [http://192.168.1.9:8080/chatme_userimages/ttestttt@gmail.com.jpg_100x100]

但只有默认的绘制R.drawable.profile_image一直显示。谁能告诉我，我在这里错过了什么吗？代码有什么问题？

*您应该创建一个自定义的 xml 布局文件，然后在方法 getInfoContent（Marker arg0）中膨胀

您的图像已准备好，但我认为它没有加载到标记上。

试试这个

 @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 position from the marker
            LatLng latLng = arg0.getPosition();
            // Getting reference to the TextView to set latitude
            TextView tvLat = (TextView) v.findViewById(R.id.tv_lat);
            // Getting reference to the TextView to set longitude
            TextView tvLng = (TextView) v.findViewById(R.id.tv_lng);
            // Setting the latitude
            tvLat.setText("Latitude:" + latLng.latitude);
            // Setting the longitude
            tvLng.setText("Longitude:"+ latLng.longitude);
            // Returning the view containing InfoWindow contents
            return v;
        }
    });

我找到了解决问题的方法，遵循地图V2信息窗口中动态内容的一些建议

和Android GoogleMap 2通过通用图像加载器在InfoWindow中使用ImageView动态更新信息

上述代码的问题在于getInfoWindow(Marker marker)在下载图像之前被调用，因此它没有显示更新的 UI。

所以我正在使用marker.showInfoWindow()更新信息窗口（），并在图像下载后marker.hideInfoWindow().

我已经在我的代码中完成了以下更改.

@Override
        public View getInfoContents(Marker marker) {
            if ( FragmentMap.this.marker != null && FragmentMap.this.marker.isInfoWindowShown()) {
                FragmentMap.this.marker.hideInfoWindow();
                FragmentMap.this.marker.showInfoWindow();
                FragmentMap.this.marker  = null ;
            }
            return null;
        }

@Override
        public View getInfoWindow(Marker marker) {
            try {
                Log.d("d", "inside getinfowindow");
                FragmentMap.this.marker = marker;
                JSONObject jsonMarker = new JSONObject(marker.getSnippet());
                String name = jsonMarker.getString("name");
                double distance = jsonMarker.getDouble("distance");
                String imagePath = jsonMarker.getString("profile_pic_address");
                String gender = jsonMarker.getString("gender");
                String birthDate = jsonMarker.getString("birthdate");
                age = hiApplication.getAge(birthDate);
                TextView tvName = ((TextView) myContentsView
                        .findViewById(R.id.tvMapChatName));
                TextView tvAge = ((TextView) myContentsView
                        .findViewById(R.id.tvMapChatAge));
                TextView tvDistance = ((TextView) myContentsView
                        .findViewById(R.id.distance));
                TextView tvGender = (TextView) myContentsView.findViewById(R.id.tvChatGender);
                RoundedImageView  image = (RoundedImageView) myContentsView.findViewById(R.id.profile_pic);
                imageLoader.displayImage(imagePath, image , defaultOptions , simpleLoader);
                tvName.setText(name);
                if(age == 0 ) tvAge.setText("");
                else tvAge.setText(age+"");
                tvGender.setText(gender);
                tvDistance.setText(new DecimalFormat("##.##").format(distance)+ " km.");
            } catch (JSONException e) {
                e.printStackTrace();
            }
            return myContentsView;
        }

内部类简单加载器

@Override
        public void onLoadingComplete(String arg0, final View view,  Bitmap bitmap) {
            markerCustomAdapter.getInfoContents(marker);
        }

更新

上面的代码在 android

4.0.4 上运行良好，但是当我在 android lolipop 上尝试这段代码时，图像没有加载。所以我遵循了将图像从 url 添加到自定义信息窗口谷歌地图 v2 并使用 http://square.github.io/picasso/毕加索图书馆。现在它对我来说工作正常。

谢谢大家。
