CheckBox复选框用法，先看效果图
选择点击按钮后，会在标题栏显示选中的项。
main.xml代码：
01
<CheckBox android:id="@+id/box1"
02
android:text="我是BOX1"
03
android:layout_width="fill_parent"
04
android:layout_height="wrap_content"
05
/>
06
<CheckBox android:id="@+id/box2"
07
android:text="我是BOX2"
08
android:layout_width="fill_parent"
09
android:layout_height="wrap_content"
10
/>
11
<Button android:id="@+id/b1"
12
android:layout_width="wrap_content"
13
android:layout_height="wrap_content"
14
android:text="按我"
15
/>
