简易到航天的实现（ListView SimpleAdapeter）

一：main 界面代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

   <ListView
       android:id="@+id/myList"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:dividerHeight="2px"
       android:layout_marginLeft="4px">

   </ListView>

</LinearLayout>
