Making TextView scrollable on Android

Question

The text I'm showing in a TextView seems to be too long to fit on one screen. My TextView needs to be scrollable. How can I go about doing that?

This is the key:

final TextView tv = new TextView(this);
tv.setBackgroundResource(R.drawable.splash);
tv.setTypeface(face);
tv.setTextSize(18);
tv.setTextColor(R.color.BROWN);
tv.setGravity(Gravity.CENTER_VERTICAL| Gravity.CENTER_HORIZONTAL);
tv.setOnTouchListener(new OnTouchListener() {
    public boolean onTouch(View v, MotionEvent e) {
        Random r = new Random();
        int i = r.nextInt(101);
        if (e.getAction() == e.ACTION_DOWN) {
            tv.setText(tips[i]);
            tv.setBackgroundResource(R.drawable.inner);
        }
        return true;
    }
});
setContentView(tv);

This is how I did it purely in XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <ScrollView
        android:id="@+id/SCROLLER_ID"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:scrollbars="vertical"
        android:fillViewport="true">

        <TextView
            android:id="@+id/TEXT_STATUS_ID"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_weight="1.0"/>
    </ScrollView>
</LinearLayout>
