Spinner的三级联动

(采用ArrayAdapter)
使用entries设置显示数组数据
android:dropDownWidth：设置下拉列表的宽度
android:dropDownSelector：设置Spinner组件的下拉框被选择的动态效果属性
android:popupBackground:下拉框的背景
使用ArrayAdapter为其设置相应数据、Spinner样式及下拉窗口样式等内容
android.R.layout.simple_spinner_item:设置spinner的样式
adapter.setDropDownViewResouce(android.R.simple_spinner_dropdown_item)：设置下拉框的样式
添加setOnItemSelectedListener(OnItemSelectedListener)事件监听器
