最近一直在搞自定义的AlertDialog，先贴一下图。

这几种都是自定义的AlertDialog，还支持从Service弹出。好了，话不多说，看使用方法：

CustomDialogBuilder.With(this)//上下文.load(R.layout.dialog_loading)//自定义的布局文件.setDimAmount(0.5f)//设置背景透明度.setCancelable(true)//是否点击区域外隐藏.setHeigh(DensityUtil.dip2px(this,100))//设置高度.setWidth(DensityUtil.dip2px(this,100))//设置宽度.setWidth(0.5f)//设置宽度，以屏幕宽度为基准，取百分比.InitView(null)//初始化View.InitEvent(null)//初始化事件.show();//显示

是不是觉得简单好多，我们关心的只有，我们该关心的，至于其他的繁琐的东西，我们不关心好伐。

我们这里看一下是怎么写的，下面会贴出GitHub链接

好吧其实我也知道你们根本不会看这些代码的，我就是要贴出来。
