用xml布局来实现，不多说，直接贴代码

Test4Activity.java 代码：

public class Test4Activity extends Activity {
   
 
 private Button button;
 private TextView textView;
 private ArrayList<HashMap<String, Object>> listItem;
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        button = (Button)findViewById(R.id.button);
        textView = (TextView)findViewById(R.id.textView);
        button.setOnClickListener(new OnClickListener(){

   @Override
&
