row, that row detail should display into toast or into Dialog box .
Here i am using Toast. But instead of displaying the names it shows

Please help me how i solve this problem

package org.kah;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.ListActivity;
import android.content.ContentValues;
import android.content.DialogInterface;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.provider.BaseColumns;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.CursorAdapter;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.Toast;
public class SQLiteDemo extends ListActivity
{
private static final int DIALOG_ID = 100;
private SQLiteDatabase database;
private CursorAdapter dataSource;
private View entryView;
private EditText firstNameEditor;
private EditText lastNameEditor;
private static final String fields[] = { "first", "last",
BaseColumns._ID };
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
DatabaseHelper helper = new DatabaseHelper(this);
database = helper.getWritableDatabase();
Cursor data = database.query("names", fields, null, null, null,
null,
null);
dataSource = new SimpleCursorAdapter(this, R.layout.row, data,
fields,
new int[] { R.id.first, R.id.last });
ListView view = getListView();
view.setHeaderDividersEnabled(true);
view.addHeaderView(getLayoutInflater().inflate(R.layout.row,
null));
setListAdapter(dataSource);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(0, DIALOG_ID, 1, R.string.addItem);
return true;
}
@Override
protected void onListItemClick(ListView l, View v, int position, long
id) {
super.onListItemClick(l, v, position, id);
// Get the item that was clicked
Object o = this.getListAdapter().getItem(position);
String keyword = o.toString();
Toast.makeText(this, "You selected: " + keyword,
Toast.LENGTH_LONG)
.show();
}
@Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
if (item.getItemId() == DIALOG_ID) {
showDialog(DIALOG_ID);
}
return true;
}
@Override
protected Dialog onCreateDialog(int id)
{
AlertDialog.Builder builder = new AlertDialog.Builder(this);
entryView = getLayoutInflater().inflate(R.layout.entry, null);
builder.setView(entryView);
firstNameEditor = (EditText)
entryView.findViewById(R.id.firstName);
lastNameEditor = (EditText)
entryView.findViewById(R.id.lastName);
builder.setTitle(R.string.addDialogTitle);
builder.setPositiveButton(R.string.addItem,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface
dialog, int which) {
dialog.dismiss();
ContentValues values = new
ContentValues();
values.put("first",
firstNameEditor.getText()
.toString());
values.put("last",
lastNameEditor.getText().toString());
database.insert("names", null,
values);
dataSource.getCursor().requery();
}
});
builder.setNegativeButton(R.string.cancelItem,
new DialogInterface.OnClickListener()
{
@Override
public void onClick(DialogInterface
dialog, int which) {
dialog.cancel();
}
});
return builder.create();
}
}
