获取城市天气信息的简单例子-----WebService

本例是通过第三方类库ksoap2来调用天气WebService的简单实例

前提：

1.下载kSoap2.jar包；

2.在AndroidManifest.xml文件中声明网络访问权限

<uses-permission android:name="android.permission.INTERNET" />//这句话放在</activity>标签后面即可；

先上代码：

1.activity_main.xml代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/container"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"       >    <EditText        android:id="@+id/cityName"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:hint="请输入城市名称"        android:ems="10" >        <requestFocus />    </EditText>    <Button        android:id="@+id/getWeather"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="获取天气信息" />       </LinearLayout>

2.MainActivity代码：
