Help with displaying HTML formatted strings from an ArrayAdapter

I appologize for the absolute beginner questions, but I am having a
tough time understanding this.

I need some help of how to display the strings that I have marked up
with simple html into a TextView. I have found "Spanned
fromHtml(String source)", but I don't know how to plug it into my java
code or really how to use it. In my code below would HistoryList be my
string source?

Here is my Java:

package com.SorenWinslow.TriumphHistory;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.ArrayAdapter;

public class TriumphHistory extends ListActivity {
String[] HistoryList;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

ArrayAdapter<String> adapter;
HistoryList = getResources().getStringArray(R.array.history);
adapter = new ArrayAdapter<String>
(this,R.layout.historylistlayout,HistoryList);
setListAdapter(adapter);

}
}

Here is a sample of history:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="history">
<item><b>1883</b><br/>Some stuff happened</item>
<item><b>1884</b><br/>Some more stuff happened <i>before</i> the other
stuff
</item>
<resources>

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:textColor="#ffffff"
android:background="#000050"
android:layout_marginTop="5px"
android:minHeight="?android:attr/listPreferredItemHeight"
android:padding="3px"
android:textSize="8pt" android:layout_gravity="top|left"/>


And here is my main.xml

<?xml version="1.0" encoding="utf-8"?>


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:textColor="#ffffff"
android:background="#000080"
android:isScrollContainer="true"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:scrollbarStyle="insideOverlay">

<ListView xmlns:android="http://schemas.android.com/apk/res/
android"
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:dividerHeight="1px"/>

</LinearLayout>

Try this:

....
String[] plainStrings =
getResources().getStringArray(R.array.history);
Spanned[] htmlStrings = new Spanned[plainStrings.length];
for(int i = 0 ; i < plainStrings.length; i++) {
htmlStrings[i] = Html.fromHtml(plainStrings[i]);
}
setListAdapter(new ArrayAdapter<CharSequence>(this,
R.layout.list_item, htmlStrings));
....
