I am trying to use a grid with a custom component but when I try to
inflate the view I get the following exception:

Here is the code I am using to try to inflate the view:
@Override
public View getView(int index, View convertView, ViewGroup parent)
{
View iconLayout;
ImageView icon;
TextView fileName;
if (convertView == null)
{
iconLayout = View.inflate(FileBrowser.this, R.layout.icon,
null);
icon = (ImageView)iconLayout.findViewById(R.id.Icon);
icon.setScaleType(ImageView.ScaleType.FIT_CENTER);
icon.setLayoutParams(new GridView.LayoutParams(50, 50));
fileName = (TextView)iconLayout.findViewById(R.id.FileName);
}
else
{
iconLayout = convertView;
icon = (ImageView)convertView.findViewById(R.id.Icon);
fileName = (TextView)convertView.findViewById(R.id.FileName);
}
icon.setImageResource(getIcon(index));
fileName.setText(mFiles.get(index).getName());
return iconLayout;
}
and here is the layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android";
android:orientation="vertical"
android:id="@+id/IconLayout">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/Icon"
android:maxHeight="48px"
android:maxWidth="48px"
android:minHeight="48px"
android:minWidth="48px" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/FileName"
android:maxLength="15"
android:maxLines="1" />
</LinearLayout>
Does anyone know what is causing this exception?
