編輯:關於Android編程
最近在做一個項目,要求實現上下能滾動,每項能左右滾動,最後效果是實現了,可數據的通信可能有點麻煩,暫時又被砍掉了,先放上來存檔,轉載請注明出處,謝謝
代碼如下

方法一:Android的界面布局可以用兩種方法,一種是在xml中布局,一種是和JAVA中Swing一樣在JAVA代碼中實現Ui界面的布局,用xml的布局管理器布局是很方便
TabLayout的默認樣式: app:theme=@style/Widget.Design.TabLayout從系統定義的該樣式繼續深入: <style name
前言通過“計算器”應用我們已經熟悉了安卓應用開發的大致流程,具備了開發的初步知識。接下來,我們將開始制作一個“視頻播放器”
周末閒著沒事,寫了個手勢解鎖的view,實現起來也蠻快的,半天多一點時間就完事。把源碼和資源貼出來,給大家分享,希望對大家有用。效果,就跟手機上的九點手勢解鎖一樣,上個圖
