        scrollView.addView(layout,new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));

Define one LinearLayout under ScrollView in xml file. Give id field to LinearLayout:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:id="@+id/<ID> >
    </LinearLayout>
</ScrollView>

Map LinearLayout in your class:

LinearLayout layout = (LinearLayout) findViewById(R.id.<ID>);

Add TextBox dynamically here:

TextView textBox = new TextView(context);
layout.addView(textBox);
