Add programmatically a scrollable linear layout

Question

I've this layout file and the java code.

I need to create a horizontally scrollable linear layout to scroll over the buttons. In this way it doesn't scroll at all.

<ScrollView
    android:id="@+id/questionListSV"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:fillViewport="true">

    <LinearLayout
        android:id="@+id/questionList_LL"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
    </LinearLayout>
</ScrollView>

for (int i =0; i<maxQuestionNo;i++) {
    Button qbtn = new Button(mContext);
    qbtn.setText(String.valueOf(i + 1));
    ll.addView(qbtn);
}

You need to use HorizontalScrollView instead of ScrollView

 <HorizontalScrollView
    android:id="@+id/questionListSV"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:fillViewport="true">

    <LinearLayout
        android:id="@+id/questionList_LL"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
    </LinearLayout>
</HorizontalScrollView>
