Answer 1

This sounds like an issue that's been reported to Google already.

If this is indeed your issue, there's a couple of suggestions at the bottom of that page for fixing it (well, more making it work than fixing it).

Answer 2

Create the layout file list_content.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/progressContainer"
            android:orientation="vertical"
            android:layout_width="match_parent" 
            android:layout_height="match_parent"
            android:visibility="gone"
            android:gravity="center">
        
        <ProgressBar style="?android:attr/progressBarStyleLarge"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content" />
        <TextView android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textAppearance="?android:attr/textAppearanceSmall"
                android:text=""
                android:paddingTop="4dip"
                android:singleLine="true" />
            
    </LinearLayout>
        
    <FrameLayout android:id="@+id/listContainer"
            android:layout_width="match_parent" 
            android:layout_height="match_parent">
            
        <ListView android:id="@android:id/list"
                android:layout_width="match_parent" 
                android:layout_height="match_parent"
                android:drawSelectorOnTop="false" />
        <TextView android:id="@+id/internalEmpty"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:gravity="center"
                android:textAppearance="?android:attr/textAppearanceLarge" />
    </FrameLayout>
        
</FrameLayout>

Put this inside your ListFragment class:

public ListView mList;
boolean mListShown;
View mProgressContainer;
View mListContainer;

public void setListShown(boolean shown, boolean animate){
    if (mListShown == shown) {
        return;
    }
    mListShown = shown;
    if (shown) {
        if (animate) {
            mProgressContainer.startAnimation(AnimationUtils.loadAnimation(
                    getActivity(), android.R.anim.fade_out));
            mListContainer.startAnimation(AnimationUtils.loadAnimation(
                    getActivity(), android.R.anim.fade_in));
        }
        mProgressContainer.setVisibility(View.GONE);
        mListContainer.setVisibility(View.VISIBLE);
    } else {
        if (animate) {
            mProgressContainer.startAnimation(AnimationUtils.loadAnimation(
                    getActivity(), android.R.anim.fade_in));
            mListContainer.startAnimation(AnimationUtils.loadAnimation(
                    getActivity(), android.R.anim.fade_out));
        }
        mProgressContainer.setVisibility(View.VISIBLE);
        mListContainer.setVisibility(View.INVISIBLE);
    }
}
public void setListShown(boolean shown){
    setListShown(shown, true);
}
public void setListShownNoAnimation(boolean shown) {
    setListShown(shown, false);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    int INTERNAL_EMPTY_ID = 0x00ff0001;
    View root = inflater.inflate(R.layout.list_content, container, false);
    (root.findViewById(R.id.internalEmpty)).setId(INTERNAL_EMPTY_ID);
    mList = (ListView) root.findViewById(android.R.id.list);
    mListContainer =  root.findViewById(R.id.listContainer);
    mProgressContainer = root.findViewById(R.id.progressContainer);
    mListShown = true;
    return root;
}

Now you can use normally:

setListShown(boolean shown);
setListShown(boolean shown, boolean animate);
setListShownNoAnimation(boolean shown);

Another solution that worked for me as well is just to put this line

<include layout="@android:layout/list_content" />

instead of your list view.

You are able to build your own content on top of it or surround it with some other views. For example, here is how my layout looks like:

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

<RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="@dimen/default_view_padding"
        android:gravity="center"
        android:weightSum="4">

    <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/btnCounterBack"
            android:src="?attr/ic_previous"
            android:background="?android:attr/selectableItemBackground"
            android:contentDescription="@null"/>

    <TextView
            android:id="@+id/tvCounterLevel"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:text="@string/counter_categories"
            android:layout_gravity="center"
            android:paddingTop="@dimen/default_view_padding"
            android:paddingBottom="@dimen/default_view_padding"
            android:layout_alignParentTop="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:gravity="center"/>

</RelativeLayout>

<LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center_vertical"
        android:background="?attr/dropShadowBackground"
        android:orientation="vertical" >

    <include layout="@android:layout/list_content" />

</LinearLayout>

Answer 4

Try to remove setListShown(true);?

I had same problem, some time ago. It's seams that you cant use it if you have custom layout in ListFragment.
