Android - EBADF（错误文件号）OnClickInfoMarker

我搜索过相关问题但没有找到。我创建了一个显示图片、名称和地址的 InfoWindowMarker。然后我创建 OnInfoWindowClickListener 将显示所选标记的纬度和经度。但是当我单击信息窗口时，我收到此错误消息。

信息窗口适配器：

public GoogleMap.InfoWindowAdapter CustomMarkerInfo = new GoogleMap.InfoWindowAdapter() {
    @Override
    public View getInfoWindow(Marker marker) {
        ViewGroup viewGroup = (ViewGroup)getLayoutInflater().inflate(R.layout.custom_info_window, null);
        ImageView ivRow = (ImageView)viewGroup.findViewById(R.id.ivRowImage);
        TextView locationName = (TextView)viewGroup.findViewById(R.id.tvRowTitle);
        TextView locationAddress = (TextView)viewGroup.findViewById(R.id.tvRowTitle2);
        Bitmap locationImage;

        locationName.setText(marker.getTitle());
        locationAddress.setText(marker.getSnippet());
        URL imageURL;
        try {
            imageURL = new URL(markerInfo.get(marker.getId()));
            locationImage = BitmapFactory.decodeStream(imageURL.openConnection().getInputStream());
            ivRow.setImageBitmap(locationImage);
        }catch (Exception e){
            e.printStackTrace();
        }
        return viewGroup;
    }

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

OnInfoWindowClickListener：

 private GoogleMap.OnInfoWindowClickListener onInfoWindowClickListener = new GoogleMap.OnInfoWindowClickListener() {
    @Override
    public void onInfoWindowClick(Marker marker) {
        LatLng myLatLng = myLatLng();
        Toast.makeText(getApplicationContext(),myLatLng.toString(),Toast.LENGTH_LONG).show();
    }
};

private final LocationListener locationListener = new LocationListener() {
    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {}

    @Override
    public void onProviderEnabled(String provider) {}

    @Override
    public void onProviderDisabled(String provider) {}

    @Override
    public void onLocationChanged(Location newLocation) {

    }
};

private LatLng myLatLng(){
    LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    String provider;
    Location location;
    LatLng myLatLng = null;

    if(locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
        provider = LocationManager.GPS_PROVIDER;
        Toast.makeText(getApplicationContext(),"GPS tidak aktif.",Toast.LENGTH_LONG).show();
    }else if(locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
        provider = LocationManager.NETWORK_PROVIDER;
    }else{
        provider = LocationManager.PASSIVE_PROVIDER;
    }


    if(locationManager.getLastKnownLocation(provider) == null){
        locationManager.requestLocationUpdates(provider,2000,10,locationListener);
        location = locationManager.getLastKnownLocation(provider);
        if(location == null){
            Toast.makeText(getApplicationContext(),"Tidak dapat menemukan lokasi saat ini, coba lagi.",Toast.LENGTH_LONG).show();
        }else{
            location = locationManager.getLastKnownLocation(provider);
            myLatLng = new LatLng(location.getLatitude(),location.getLongitude());
        }
    }else{
        location = locationManager.getLastKnownLocation(provider);
        myLatLng = new LatLng(location.getLatitude(),location.getLongitude());
    }
    return myLatLng == null ? myLatLng() : myLatLng;
}

感谢任何解决方案。

更新：从加载的 JSON 创建的标记。如果是的话可能会导致这个问题。

这可能是线程问题。你的viewGroup在从 URL 加载图像之前返回。解决这个问题的一个简单方法就是使用第三方图片加载库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));
 }

然后你可以有一个私有帮助器方法来确保第一次单击时显示异步：

 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() {}
    }

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 http://androidfreakers.blogspot.com/2013/08/display-custom-info-window-with.html（但是比使用Picasso从URL加载要复杂一些）
