(採用ArrayAdapter)
使用entries設定顯示陣列資料
android:dropDownWidth：設定下拉列表的寬度
android:dropDownSelector：設定Spinner元件的下拉框被選擇的動態效果屬性
android:popupBackground:下拉框的背景
使用ArrayAdapter為其設定相應資料、Spinner樣式及下拉視窗樣式等內容
android.R.layout.simple_spinner_item:設定spinner的樣式
adapter.setDropDownViewResouce(android.R.simple_spinner_dropdown_item)：設定下拉框的樣式
新增setOnItemSelectedListener(OnItemSelectedListener)事件監聽器
