how to set android progress bar in center of the screen

I am trying to show the progress bar in the center of the screen, but it doesn't show up in the center. Below is my layout. What am i doing wrong here? Basically this is a layout to show image and android gallery widget on top. When the user clicks on the thumbnails, I am loading an image from the web and I want to show the progress dialog while the image is loading.

<LinearLayout xmlns:android=""
android:id="@+id/container" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical">

<Gallery android:id="@+id/gallery" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:gravity="top" />

<ImageView android:id="@+id/actualimage" android:scaleType="fitCenter"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:visibility="gone" android:layout_gravity="center_vertical|center_horizontal|center"
android:adjustViewBounds="true" />

<ProgressBar android:id="@+android:id/progress_small1"
android:layout_height="wrap_content" android:layout_width="wrap_content"
android:visibility="visible" android:layout_gravity="center_vertical|center_horizontal"
android:gravity="center_vertical|center_horizontal" />

Using a LinearLayout will stack your views vertically. Right now, your ImageView and ProgressBar are fighting for the centered position. For this type of situation, I would definitely recommend a RelativeLayout.

With RelativeLayout, you use android:layout_centerInParent="true".
