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);
