making a linear layout horizontally scrollable

Question

How can I make a Linear layout horizontally scrollable? I just wrap a linear layout in myscrollview, I did what's needed in my XML file too but it still cannot scroll horizontally for contents which exceeds the linear layout size. Here is my XML:

    <ScrollView 
        android:id="@+id/scroller"
        android:layout_marginTop="16dip"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/popup"
        android:fadingEdgeLength="5dip"
        android:scrollbars="horizontal"
        android:overScrollMode="always" 
        android:isScrollContainer="true" 
        android:scrollbarAlwaysDrawHorizontalTrack="true"
        >

        <LinearLayout
            android:id="@+id/tracks"
            android:orientation="horizontal"
            android:layout_width="wrap_content"
            android:layout_height="fill_parent"
            android:layout_weight="1"
            android:padding="10dip"/>

    </ScrollView >

    <ImageView
        android:id="@+id/arrow_up"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/arrow_up" />

    <ImageView
        android:id="@+id/arrow_down"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/scroller"
        android:layout_marginTop="-4dip"
        android:src="@drawable/arrow_down" />

</RelativeLayout>

  public class HorizontalscroolActivity extends Activity {


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ImageButton btn11 = (ImageButton) findViewById(R.id.imageButton1);


    ImageButton btn2 = (ImageButton) findViewById(R.id.imageButton2);
