Horizontal scroll view does not scroll properly

Question

I have a horizontal scroll view that moves horizontally only 100 dp while it should be much wider, not scroll all the content. What can I do?

<HorizontalScrollView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:fillViewport="true">

    <LinearLayout
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_marginTop="10dp" 
      android:orientation="vertical">

        <LinearLayout
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_marginTop="10dp"
          android:orientation="horizontal" >

           <TextView

            android:layout_height="30dp"
            android:layout_marginLeft="10dp"
            android:gravity="center_vertical"
            android:text="@string/oggi"
            android:textSize="12dp" />

          <LinearLayout

            android:layout_width="455dp"
            android:layout_height="2dp"
            android:background="#000000"
           android:layout_gravity="center"
           android:orientation="horizontal" >

          </LinearLayout>

I'm not 100% sure but did you try making your scrollview fill parent? If your scrollview and your layout has the same sizes, there's no point in using a scrollview. ScrollView needs to have a size so that if the layout exceed the size of your scrollview, you can scroll.
