Doc: Fixed a code sample to use standard methods. Also some formatting

uses a string array as the data source:</p>

<pre>

SpinnerAdapter mSpinnerAdapter = ArrayAdapter.createFromResource(this, R.array.action_list,

          android.R.layout.simple_spinner_dropdown_item);

SpinnerAdapter mSpinnerAdapter = ArrayAdapter.createFromResource(this,

        R.array.action_list, android.R.layout.simple_spinner_dropdown_item);

</pre>

<p>The {@link android.widget.ArrayAdapter#createFromResource createFromResource()} method takes

  public boolean onNavigationItemSelected(int position, long itemId) {

    // Create new fragment from our own Fragment class

    ListContentFragment newFragment = new ListContentFragment();

    FragmentTransaction ft = openFragmentTransaction();

    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();

    // Replace whatever is in the fragment container with this fragment

    //  and give the fragment a tag name equal to the string at the position selected

    // and give the fragment a tag name equal to the string at the position

    // selected

    ft.replace(R.id.fragment_container, newFragment, strings[position]);

    // Apply changes

    ft.commit();

    return true;

    @Override

    public void onAttach(Activity activity) {

      // This is the first callback received; here we can set the text for

      // the fragment as defined by the tag specified during the fragment transaction

      // the fragment as defined by the tag specified during the fragment

      // transaction

      super.onAttach(activity);

      mText = getTag();

    }
