android - Using the "animated circle" in an ImageView while loading stuff

Question

I am currently using in my application a listview that need maybe one second to be displayed.

What I currently do is using the @id/android:empty property of the listview to create a "loading" text.

 <TextView android:id="@id/android:empty"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:background="#FF0000"
           android:text="Loading..."/>

Now, I would like to replace that with the animated circle that is used in a loading dialog instead of this text, i guess you all know what I mean:

Edit: I do not want a dialog. I want to show that inside my layout.

Thank a lot for your help!

Simply put this block of xml in your activity layout file:

<RelativeLayout
    android:id="@+id/loadingPanel"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center" >

    <ProgressBar
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:indeterminate="true" />
</RelativeLayout>

And when you finish loading, call this one line:

findViewById(R.id.loadingPanel).setVisibility(View.GONE);

The result (and it spins too):
