Using android Inflate outside of onCreateView

Question

I have a fragment. In my On create I do set my inflater as follows.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    v= inflater.inflate(R.layout.dashboard_two, container, false);  
    getActivity().getActionBar().setTitle("NV Technologies");
    new HttpRequestFaultList().execute();
    return v;
}

I want to change the inflater ti display A different Layout outside of onCreate view. I have tried:

v= inflater.inflate(R.layout.custom_dash, container, false);

custom_dash.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:id="@+id/testFrag"
  android:layout_height="match_parent"
  android:orientation="vertical" >

   <ImageView
      android:id="@+id/imageView1"
      android:layout_width="269dp"
      android:layout_height="387dp"
      android:layout_gravity="center"
      android:scaleType="centerInside"
      android:src="@drawable/message" />

</LinearLayout>

But because it is outside of the onCreate there does not exist an inflater or a container. I want to change the Layout in a catch block and if there is a catch the Layout must change. Is it even possible to change the layout in the Fragment but outside of the onCreate method? And how

This seems like something you should just use a separate Fragment for. If the UI is entirely different, you should just replace the Fragment. — Kevin Coppock, Oct 09 '14 at 22:22

You can inflate from within your fragment like this:

FrameLayout container = (FrameLayout) getActivity().findViewById(R.id.fragment_container);
LayoutInflater.from(getActivity())
        .inflate(R.layout.custom_dash, container, false);

If that doesn't work out for you (for some reason), you can always save references to both the inflater and the container in your onCreateView method and use them whenever:

private LayoutInflater mInflater;
private ViewGroup mContainer;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    mInflater = inflater;
    mContainer = container;
    v = inflater.inflate(R.layout.dashboard_two, container, false);  
    getActivity().getActionBar().setTitle("NV Technologies");
    new HttpRequestFaultList().execute();
    return v;
}

public View someOtherMethod() {
    mInflater.inflate(R.layout.custom_dash, mContainer, false);
}

What do you mean with fragment container. I placed the custom_dash.xml in my question. Is it one of the fields in that xml? – Jonathan Oct 09 '14 at 20:52
@Jonathan fragment_container is the id of the view that holds you fragment. It should be located in you activity's layout and probably is a FrameLayout. Updated my answer. – Simas Oct 09 '14 at 20:54
@Simas How would you implement `someOtherMethod()`? If I try to reinflate a `View` in `onResume()`, doing something like: `mView = someOtherMethod();` has no effect. The `View` doesn't inflate. – pez Jul 16 '15 at 04:21

@pez in this case inflating doesn't add the view to the hierarchy. You need to do it manually afterwards, e.g. mContainer.addView(mView); – Simas Jul 16 '15 at 05:23
@Simas Doesn't seem to work for me, because it seems like the `View` doesn't actually inflate. If you're interested, see my question [here](http://stackoverflow.com/questions/31359994/swap-nested-fragments-onresume) for more information. Thanks. – pez Jul 17 '15 at 03:35
