首先还是先看一下效果
不说废话,直接上代码:
调用处代码,就这两句,放在要调用的onclick方法中:
birth = new SelectBirthday(PersonalProfileActivity.this); birth.showAtLocation(PersonalProfileActivity.this.findViewById(R.id.activity_root),//这里标红要注意下,在你当前activity的页面xml中最外层的父节点定义一个id,不会的可以参照原版资源 Gravity.BOTTOM, 0, 0);
下面贴插件代码,这个代码也是我从网上下的,为了适应项目有改动,原版只是一个展示效果,拿到任何一个项目都是用不了的,等下我会把原版资源分享出来,要用的时候直接把原版资源拷贝进项目里,再参照我改的插件代码处修改就行,改动处我会标红
