谢谢你的帮助


更新:从加载的JSON创建标记。如果是,则可能导致此问题。

这可能是线程问题。在从URL加载图像之前,将返回您的
视图组
。解决此问题的一个简单方法是使用第三方图像加载库
Picasso

示例代码:

 ImageView imageView = (ImageView)myContentsView.findViewById(R.id.ivRowImage);
 if (not_first_time_showing_info_window) {
     Picasso.with(getApplicationContext()).load("YOUR_IMG_URL").into(imageView);
 } else { // if it's the first time, load the image with the callback set
     not_first_time_showing_info_window=true;
     Picasso.with(getApplicationContext()).load("YOUR_IMG_URL").into(imageView,new InfoWindowRefresher(marker));
 }
然后您可以使用private helper方法来确保第一次单击中显示的异步:

 private class InfoWindowRefresher implements Callback {
        private Marker markerToRefresh;

        private InfoWindowRefresher(Marker markerToRefresh) {
            this.markerToRefresh = markerToRefresh;
        }

        @Override
        public void onSuccess() {
            markerToRefresh.showInfoWindow();
        }

        @Override
        public void onError() {}
    }
您可以参考此GitHub页面了解完整的实现:

如果您真的想使用ImageLoader,可以查看以下帖子:
(但与使用毕加索从URL加载相比要复杂得多)

我尝试使用默认信息窗口,但仍然面临同样的问题。我将尝试在我以前的活动中使用毕加索,该活动使用AsyncTask加载图像。也许它会解决这个问题。谢谢,我把所有的图像加载器都改成毕加索,合子错误消失了。
