2、的值，可以在edittext編輯工作事項(xiàng)，通過(guò)listview顯示所有的工作事項(xiàng)。利用service設(shè)計(jì)視力保護(hù)程序：服務(wù)的生命周期比activity簡(jiǎn)單，但因?yàn)榉?wù)可能在用戶不知情的情況下在后臺(tái)運(yùn)行，因此需要關(guān)注服務(wù)如何創(chuàng)建和銷毀。3、 程序源碼main.xmlmcy.xmllinearlayout android:id=+id/linearlayout01 android:layout_width=fill_parent android:layout_height=fill_parent xmlns:android= strings.xml hello world, mcy579! mcy
