ListFragment Layout from xml

Question

How to create a ListFragment (of the support v4 library) layout from xml? ListFragment sets up its layout programmatically, so if you want to modify it, you need to mess with add/remove view.

Solution

I've converted the created layout to xml, you can add/remove your widgets or e.g. add pulltorefresh solutions. You shouldn't change the needed ids. Because of internal ids needed for some of the widgets an helper function needs to be called and it needs to be in support v4 namespace since constants are internal with default visibility.

list_loader.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:id="@+id/progress_container_id"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:orientation="vertical"
        android:visibility="gone" >

        <ProgressBar
            style="?android:attr/progressBarStyleLarge"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
    </LinearLayout>

    <FrameLayout
        android:id="@+id/list_container_id"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <TextView
            android:id="@+id/empty_id"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center" />

        <ListView
            android:id="@android:id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:drawSelectorOnTop="false" >
        </ListView>
    </FrameLayout>
</FrameLayout>

and the class ListFragmentLayout in android.support.v4.app (in your project, you don't need to modify support v4 jar)

package android.support.v4.app;

import your.package.R;
import android.view.View;

public class ListFragmentLayout
{
    public static void setupIds(View view)
    {
        view.findViewById(R.id.empty_id).setId(ListFragment.INTERNAL_EMPTY_ID);
        view.findViewById(R.id.progress_container_id).setId(ListFragment.INTERNAL_PROGRESS_CONTAINER_ID);
        view.findViewById(R.id.list_container_id).setId(ListFragment.INTERNAL_LIST_CONTAINER_ID);
    }
}

in your fragment that extends ListFragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    View view = inflater.inflate(R.layout.list_loader, container, false);
    ListFragmentLayout.setupIds(view);
    return view;
}
