I had the same issue and finally figured it out. This is for a vertical ScrollView.

Put your ScrollView inside a RelativeLayout and center it in the RelativeLayout. In order for this to work, your ScrollView should have

android:layout_height="wrap_content" 

This is how the final code should look like:

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent">      <ScrollView         android:id="@+id/scrollView1"         android:layout_width="fill_parent"         android:layout_height="wrap_content"          android:layout_centerVertical="true" >          <LinearLayout             android:id="@+id/linearLayout1"             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:orientation="vertical">              <Button                 android:id="@+id/button1"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:text="b1"/>             <Button                 android:id="@+id/button2"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:text="b2"/>             <Button                 android:id="@+id/button3"                 android:layout_width="wrap_content"                 android:layout_height="wrap_content"                 android:text="b3"/>         </LinearLayout>      </ScrollView>  </RelativeLayout>

How about this?

<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/scrollView1"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:paddingTop="12dp"     android:paddingBottom="20dp"     android:scrollbarStyle="outsideOverlay" >       <LinearLayout         android:id="@+id/linearLayout1"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:orientation="vertical"          android:layout_gravity="center"         android:gravity="center">          <Button             android:id="@+id/button1"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:text="check"              android:gravity="center_vertical|center_horizontal"/>     </LinearLayout>  </ScrollView>
