Custom SimpleAdapter only shows Sample Text Android

Before making my own SimpleAdapter object because I wanted to change the color of the rows, I was just using new SimpleAdapter(...). Now that I am using my own custom SimpleAdapter, the row color is changing, but my text is not getting updated. I have called adapter.notifyDataSetChanged(), but it is still showing only the sample text- "TextView". As I said, everything was working fine when I didn't create my own adapter. I suspect it might have something to do with the order I am initializing things:

public class AddScreen extends Activity implements OnClickListener,
    OnItemClickListener, OnItemLongClickListener {
SimpleAdapter adapter;
List<HashMap<String, String>> painItems = new ArrayList<HashMap<String, String>>();
ListView listthings;
int[] to;
    String[] from;

public void onCreate(Bundle savedInstanceState) {
...
listthings = (ListView) findViewById(R.id.listthings);
    from = new String[] { "row_1", "row_2" };
    to = new int[] { R.id.row1, R.id.row2 };

    adapter = new Adapter(this, painItems, R.layout.mylistlayout,
            from, to);

    listthings.setAdapter(adapter);
...
}

public class Adapter extends SimpleAdapter{
    HashMap<String, String> map = new HashMap<String, String>();
    public Adapter(Context context, List<? extends Map<String, String>> data,
            int resource, String[] from, int[] to) {
        super(context, data, resource, from, to);

    }
@Override
    public View getView(int position, View convertView, ViewGroup parent){
        View row = convertView;
        if (row == null) {
            LayoutInflater mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            row = mInflater.inflate(R.layout.mylistlayout, parent, false);
            }
        row.setBackgroundColor(0xFF0000FF);
       TextView rw1 = (TextView)findViewById(R.id.row1);
      // TextView rw2 = (TextView)findViewById(R.id.row2);
       rw1.setText(map.get(position));
       return row;
    }

}
// to add the item, put it in the map, and add the map into the list
private void addItem() {
    HashMap<String, String> map = new HashMap<String, String>();
    map.put("row_1", row1);
    map.put("row_2", row2);
    map.put("row_3", painLevelString);
    map.put("row_4", painLocation);
    map.put("row_5", timeOfPainString);
    map.put("row_6",textTreatmentString);
    painItems.add(map);

        adapter.notifyDataSetChanged();




}

EDIT:Added Code

This is how I am getting the data from the intent(onActivityResult()), placed before the addItem Code:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == 1) {
        row1 = data.getStringExtra("com.painLogger.row1");
        row2 = data.getStringExtra("com.painLogger.row2");

        painLevelString = data.getStringExtra("com.painLogger.painLevel");
        painLocation = data.getStringExtra("painLocation");
        timeOfPainString = data.getStringExtra("com.painLogger.painTime");
        textTreatmentString = data
                .getStringExtra("com.p开发者_StackOverflow社区ainLogger.treatment");
        addItem();
    }
}

*Also, just in case this is relevant the order of placement is this: onCreate() -> custom Adapter class -> onActivityResult() -> addItem()* **

Here is a screenshot of what it looks like. The two TextView fields in each item should be filled with info(which they were, until I did this).

If it worked previously with just using new SimpleAdapter(...) then in your getView(...) implementation change the first line to this:

View row = super.getView(position, convertView, parent);

And see if that is what you're expecting. Take out the LayoutInflater stuff too.

In getView(), about where you are setting the row background, you should also set the text for the TextView.

Calling notifyDataSetChanged(), doesn't automagically set your texts right, it just causes the ListView to redraw the visible rows with the new data...practically calling getView() for each row that needs a refresh.

I also suggest setting the background color from the mylistlayout.xml file, and if the getView() function starts taking on a few findViewByID's, you should also consider using a "view holder" approach like in this sample: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html

You need to set the text in getView(). Like this:

public View getView(int position, View convertView, ViewGroup parent){

    TextView text;

    if (convertView == null) {
        LayoutInflater mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.mylistlayout, parent, false);
        text = (TextView) convertView.findViewById(R.id.more_list_text);
    }
    convertView.setBackgroundColor(0xFF0000FF);
    text.setText(map.get(position));
    return convertView;
}

Also, and this is VERY important - store you map as a member variable of the SimpleAdapter
ie, put this line at the top of your object definition:

HashMap<String, String> map = new HashMap<String, String>();
