Question

I am trying to enter something into two different EditTexts, then display them onto one item of a list. My code looks like this, and compiles, but does not add the item. Any help appreciated.

package com.painLogger;

import java.util.ArrayList; ///ALL IMPORTS

public class PainLoggerActivity extends Activity implements OnClickListener, 
OnKeyListener {
/** Called when the activity is first created. */
EditText txtItem;
EditText txtItem2;
Button btnAdd;
ListView listItems; 
ArrayAdapter<String> aa;
List<HashMap<String, String>> painItems = new ArrayList<HashMap<String, String>>();

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    txtItem = (EditText)findViewById(R.id.txtItem);
    txtItem2 = (EditText)findViewById(R.id.txtItem2);

    btnAdd = (Button)findViewById(R.id.btnAdd);
    listItems = (ListView)findViewById(R.id.listItems);

    btnAdd.setOnClickListener(this);

    String[] from = new String[] {"row_1", "row_2"};
    int[] to = new int[] { R.id.row1, R.id.row2};

    SimpleAdapter adapter = new SimpleAdapter(this, painItems, R.layout.mylistlayout, 
    from, to);
    listItems.setAdapter(adapter);




}
private void addItem(){      
              HashMap<String,String>map = new HashMap<String, String>();
                    map.put("row_1",txtItem.getText().toString());
                    map.put("row_2",txtItem2.getText().toString());
                    painItems.add(map);

    }
@Override
public void onClick(View v) {
    if(v == this.btnAdd)
        addItem();

}
@Override
public boolean onKey(View v, int keyCode, KeyEvent event) {

    if(event.getAction() == KeyEvent.ACTION_DOWN && keyCode == 
            KeyEvent.KEYCODE_DPAD_CENTER){
        this.addItem();
    }
    return false;

}

}

Have you tried manually updating the display with

adapter.notifyDataSetChanged();

that may help or try to log exactly what is going in and out of your list.
