思路：就是先設置Gridlayout的行列數，然后往里面放置一定數目的自定義日歷按鈕控件，最后實現日歷邏輯就可以了。
步驟：
第一步：自定義日歷控件（初步）
第二步：實現自定義單個日期按鈕控件
第三步：將第二步得到的控件動態添加到第一步的布局中，并實現日期邏輯
第四步：編寫單個日期點擊監聽器接口

//設置下標是index的日期按鈕的點擊事件監聽器public void setOnClickButtonListener(OnClickListener l,int index){ buttons[index].setOnClickListener(l); }以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
