自定义 popWindow弹框工具包

　　前言：因为Android 没有像IOS一样的ActionSheet，虽然在github上看到有一些类似ActionSheet的库，总觉得不好用，不如自己写一个弹框通用类，样式全部自已来多好。

　　Step 1

　　废话不多说，直接上代码。

}

　　 Step 2

　 make a example.举一个分享的例子吧。

　　点击分享，弹出这样的一个分享框。

　　Step 3

　　怎么用呢？

1.调用的函数，展示一个分享的pop弹框，用kotlin来写。　声明一下：popWindow_share是CustomPopWindow类型的。　

fun showShareDialog(title:String,content:String,link:String,id:String){
        val contentView:View=LayoutInflater.from(context).inflate(R.layout.ask_share,null)
        hanleShareDialog(contentView,title,content,link,id)//分享处理函数
        popWindow_share= CustomPopWindow.PopupWindowBuilder(context)
                .setView(contentView)
                .enableBackgroundDark(true)
                .setBgDarkAlpha(0.7f)
                .setFocusable(true)
                .setOutsideTouchable(true)
                .setAnimationStyle(R.style.ask_share_anim)
                .create()
        popWindow_share!!.showAtLocation(ask_main_right_btn,Gravity.CENTER,0,0)

    }

View Code

　 2.分享的布局--ask_share.xml
