Remove Progress bar from ScrollView and place it as the first child of parent layout and use android:layout_centerInParent="true"

  <RelativeLayout 
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/relativeLayout1"
        android:orientation="vertical"    
        android:background="#F1F1F1">

         <ProgressBar
            android:id="@+id/progressBar"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"    
            android:indeterminateDrawable="@drawable/my_progress_indeterminate"
            android:layout_centerInParent="true" >
         </ProgressBar>

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