title: Android - Getting context of a fragment in a pager
body: <p>I have a android application using a pager as navigation. For the tabs I have 3 layouts as content. On one of the fragments is a gallery and I want to add images to it. For that I have to set an ImageAdapter but I need to know how to access the context of a fragment.</p>
  
  <pre><code>final LayoutInflater factory = getLayoutInflater();
  final View view = factory.inflate(R.layout.pictures, null);
  Gallery g = (Gallery) view.findViewById(R.id.gallery1);
  g.setAdapter(new ImageAdapter(view.getContext()));
  </code></pre>
  
  <p>I use this code above in the onCreate method to get the gallery from a layout that is not the contentview.
  I have to give a Context to the ImageAdapter. But what context do I have to set there?</p>
  
  <p><strong>EDIT:</strong> This is my complete code:</p>
