Android程序的基本組件有4個,分別為:Activity,BroadcastReceiver,ContentProvider和Service。Activity(活動窗
從ImageButton這個字面意思上來看,它是一個圖片按鈕,那麼我們就可以使用它做一個我們想要的圖片按鈕了,但是我們在實際使用的過程當中,就會發現該按鈕的使用並沒有想像
標准VideoView播放示例 在Android SDK中的ApiDemos內, 提供標准播放視頻的代碼,使用VideoView
最開始使用AndroidStudio的時候,各種不適應,各種懷戀Eclipse,寫了幾千行代碼勉強熟悉了AndroidStudio後,感覺AndroidStudio不要太
