Android: Adding view dynamically in a nested layout

I have an abc.xml with the following structure.

<ScrollView
  android:layout_width="match_parent"
  android:layout_height="match_parent">
 <RelativeView
   android:layout_width="match_parent"
   android:layout_height="wrap_content">
  <LinearLayout
    android:id="@+id/linear"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    >
  </LinearLayout>
 </RelativeLayout>
</ScrollView>

I want to add textviews dynamically to linear layout. Below is my code. I don't get any errors but I am not getting the desired results.

LayoutInflater Inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = Inflater.inflate(R.layout.abc, null);

LinearLayout layout = (LinearLayout) view.findViewById(R.id.linear);

        TextView Tag = new TextView(getActivity());
        Tag.setText("textString");
        Tag.setBackgroundResource(R.color.bg_color);
        Tag.setTextAppearance(getActivity(), R.style.SmallFont);
        layout.addView(Tag);
