樣式二：android.R.layout.simple_list_item_2 (一行 text 較大，一行 text 較小)
樣式三：android.R.layout.simple_list_item_single_choice (單選)
樣式四：android.R.layout.simple_list_item_multiple_choice (複選)
樣式五：android.R.layout.simple_list_item_checked (勾選盒+單選)
樣式六：android.R.layout.simple_list_item_checked (勾選盒+複選)
樣式一：android.R.layout.simple_list_item_1 (一行 text)
樣式二：android.R.layout.simple_list_item_2 (一行 text 較大，一行 text 較小)
