including list_content into list layout to retain ListFragment functionality

Question

First of, I\'m using The Android Compatibility Library V4 rev.3 for my 1.6(Donut)

When you first create a ListFragment it displays an indeterminant progress indicator u

Answer 1

The ListFragment included in the compatibility library doesn't appear to use that layout (list_content) as the real one does. This might be because it is offered as a jar and it is not possible to package resources. Here are the contents of its onCreateView:

ListFragment from compatibility library:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    final Context context = getActivity();

    FrameLayout root = new FrameLayout(context);

    // ------------------------------------------------------------------

    LinearLayout pframe = new LinearLayout(context);
    pframe.setId(INTERNAL_PROGRESS_CONTAINER_ID);
    pframe.setOrientation(LinearLayout.VERTICAL);
    pframe.setVisibility(View.GONE);
    pframe.setGravity(Gravity.CENTER);

    ProgressBar progress = new ProgressBar(context, null,
            android.R.attr.progressBarStyleLarge);
    pframe.addView(progress, new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));

    root.addView(pframe, new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

    // ------------------------------------------------------------------

    FrameLayout lframe = new FrameLayout(context);
    lframe.setId(INTERNAL_LIST_CONTAINER_ID);

    TextView tv = new TextView(getActivity());
    tv.setId(INTERNAL_EMPTY_ID);
    tv.setGravity(Gravity.CENTER);
    lframe.addView(tv, new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

    ListView lv = new ListView(getActivity());
    lv.setId(android.R.id.list);
    lv.setDrawSelectorOnTop(false);
    lframe.addView(lv, new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

    root.addView(lframe, new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

    // ------------------------------------------------------------------

    root.setLayoutParams(new FrameLayout.LayoutParams(
            ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT));

    return root;
}

ListFragment from Android 4.0:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(com.android.internal.R.layout.list_content, container, false);
}

Given the choice between copying the layout file from APIv11 source and including this view initialisation code, I think it is clear which one would be considered 'hackery' ;)
