自定义SimpleAdapter只显示示例​​文本的Andr​​oid

在做我自己的SimpleAdapter对象，因为我想改变行的颜色，我只是用新的SimpleAdapter（...）。现在，我用我自己的自定义SimpleAdapter，该行的颜色是变化的，但我的文字是不会得到更新。我呼吁adapter.notifyDataSetChanged（），但它仍然只显示文本的样本的TextView。正如我所说，一切工作的时候我没有创造我自己的适配器罚款。我怀疑这可能是与我初始化事物的秩序：

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();




}

编辑：添加code

这是我如何从意图（onActivityResult（）），置于前的addItem code获取数据：

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.painLogger.treatment");
        addItem();
    }
}

的*此外，为了以防万一，这是有关安置的顺序是这样的：的onCreate（） - >自定义适配器类 - > onActivityResult（） - >的addItem（）* **

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

下面是什么样子的屏幕截图。在每个项目两个TextView的领域应该充满信息（其中他们，直到我这样做）。

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).
