            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                    long arg3) {
                    new AlertDialog.Builder(MainActivity.this).setMessage("您选中的是:"+names[arg2]).show();
            }
        });
    }
    
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

ps:1.simpleadapter的初始化。

      第一个为上下文，第二个为列表项，第三个为界面布局文件的资源ID，第四个为列表项的Key，第五个为填充的组件.

     2. 列表项资源文件的布局。
