每次点击我的错误都会显示`Listview`到`Activity`我在下面显示它并且在尝试显示它时崩溃但它不会使整个应用程序崩溃。



这里它说错误位于：



ImageLoader imageLoaderFS = AppController.getInstance（）。getImageLoader（）;

字符串bitmapfull = i.getStringExtra（ imagefs）;

NetworkImageView thumbNailFS =（NetworkImageView）findViewById（R.id.thumbnailFS）;

thumbNailFS.setImageUrl （bitmapfull，imageLoaderFS）;



任何帮助将不胜感激



这是代码如果需要，其余的活动

The error shows whenever I click from my `Listview` to the `Activity` I showed below and it crashes when trying to show it but it does not crash the whole app.

This where it says the error is located:

ImageLoader imageLoaderFS = AppController.getInstance().getImageLoader();
String bitmapfull = i.getStringExtra("imagefs");
NetworkImageView thumbNailFS = (NetworkImageView) findViewById(R.id.thumbnailFS);
thumbNailFS.setImageUrl(bitmapfull, imageLoaderFS);

Any help would be appreciated

Here is the code for the rest of that activity if needed
