Android - EBADF（坏文件编号）OnClickInfoMarker [英] Android - EBADF (Bad file number) OnClickInfoMarker
问题描述
我已经搜索了相关的问题，但找不到它。我创建了一个显示图片，名称和地址的InfoWindowMarker。然后我创建OnInfoWindowClickListener，它将显示所选标记的纬度和经度。但是，当我点击信息窗口，我得到了这个错误信息。

感谢您提供任何解决方案。
更新：从加载的JSON创建标记。如果这可能导致此问题。
这可能是一个线程问题。在从URL加载图像之前，会返回 viewGroup 。解决此问题的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）; $（b）if（not_first_time_showing_info_window）{
Picasso.with（getApplicationContext（））。load（YOUR_IMG_URL）。（imageView）;
} else {//如果这是第一次，使用回调集
加载图像not_first_time_showing_info_window = true;
Picasso.with（getApplicationContext（））。load（YOUR_IMG_URL）。（imageView，new InfoWindowRefresher（marker））;
}
然后你可以有一个专用的辅助方法来确保异步显示第一次点击：
private class InfoWindowRefresher实现回调{
private Marker markerToRefresh;
私人InfoWindowRefresher（Marker markerToRefresh）{
this.markerToRefresh = markerToRefresh;
}
@Override
public void onSuccess（）{
markerToRefresh.showInfoWindow（）;
$ b @Override
public void onError（）{}
}
你可以参考这个GitHub页面来获得完整的实现： https://github.com/jbj88817/GoogleMap-InfoWindow-android/blob/master/app/src/main/java/com/ bjiang / map_ex / MainActivity.java
如果你真的想用ImageLoader来做，你可以看看这篇文章： http://androidfreakers.blogspot.com/2013/08/display-custom-info- window-with.html
（但与使用Picasso从URL加载相比，它更复杂）
I have searched related issues but can't find it. I create an InfoWindowMarker which shows Picture, Name and Address. Then i create OnInfoWindowClickListener that will showing Latitude and Longitude of selected Marker. But when i click the Info Window i got this error message.

Thanks for any solution.
Update: Markers created from loaded JSON. If it is could causing this issue.
This might be a threading issue. Your viewGroup is returned before your image is load from the URL. An easy way to solve the problem is to use the third party image loading library Picasso.
Sample code:
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));
}
And then you can have a private helper method to make sure the asynchronous shown in the first click:
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() {}
}
You can refer to this GitHub page for complete implementation: https://github.com/jbj88817/GoogleMap-InfoWindow-android/blob/master/app/src/main/java/com/bjiang/map_ex/MainActivity.java
If you really want to do it with ImageLoader, you can check out this post: http://androidfreakers.blogspot.com/2013/08/display-custom-info-window-with.html (But it is more complicated compared to using Picasso to load from URL)
