C# mono ListView实例带按钮事件

在网上找到个JAVA的实例看起来不错 就是没有按钮事件,

现在把他改成VS mono 平台开发,如下,

Layout文件夹下 city_item.axml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="0dip"
android:paddingLeft="0dip"
android:background="#9ACD32">
<ImageView
android:paddingTop="0dip"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/weather_image" />
<Button
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="35dp"
android:layout_marginRight="0px"
android:layout_marginBottom="0px"
android:id="@+id/btn_click" />
<TextView
android:id="@+id/city"
android:layout_width="fill_parent"
android:paddingTop="0dip"
android:layout_height="35dp"
android:textColor="#ffffff" />
</RelativeLayout>

Layout文件夹下 content_item.axml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout02"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="0dip"
android:paddingLeft="0dip"
android:paddingRight="0dip">
<!--android:background="@drawable/listview_bg"-->
<ImageView
android:paddingTop="0dip"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/weather_image" />
<TextView
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:id="@+id/content"
android:paddingTop="0dip" />
<TextView
android:text=""
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_below="@+id/content"
android:id="@+id/date"
android:paddingRight="0dip" />
</RelativeLayout>

Layout文件夹下 Main.axml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:dividerHeight="1dip"
android:id="@+id/list_items" />
<!--android:divider="@color/white"-->
</LinearLayout>

Layout文件夹下 layout1.axml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px">

</LinearLayout>

只为实现,不为别的 ,运行图如下,
