I have a `Fragment` with a `ListView`. In the adapter I want to create a dialog.

```
class ViewHolder {
...
  @Override
  public void onClick(View v) {
    ...
    AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
    ...
   }
...
}

```

`mContext` is the `Context` from my `Fragment`, which I save global when the adapter is created.
I get the error.

`unable to add window -- token null is not for an application`

The method `getActivity()` is not available so how to get the `Context` of my `Activity`?
