Android应用开发UI（多选框）

Android平台使用CheckBox来实现多项选择。效果图如下：

 

代码：

1.res/values/string.xml

 

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="title_tx">调查：你喜欢Android的原因：</string>
    <string name="app_name">A007</string>
    <string name="checkBox1">无界限的应用程序</string>
    <string name="checkBox2">应用程序是在平等的条件下创建的。</string>
    <string name="checkBox3">应用程序可以轻松的嵌入到网络。</string>
    <string name="checkBox4">应用程序可以并行运行。</string>
    <string name="btn_submit">提交</string>
    <string name="u_selected">你选择了：</string>
    <string name="i_tem">项。</string>
     <string name="about_80080088">更多详情，可登录http://www.80080088.com了解。</string>
</resources>

 

 

2.res/layout/main.xml

<?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"
    >
	<TextView  
	    android:layout_width="fill_parent" 
	    android:layout_height="wrap_content" 
	    android:text="@string/title_tx"
	    android:id="@+id/title_tx"/>
	<TextView 
		android:layout_width="wrap_content" 
		android:layout_height="wrap_content" 
		android:id="@+id/about_80080088">
	</TextView>
	<CheckBox
