CommonDialog是一个基于AlertDialog的封装，支持弹出动画。
这个库的主要作用就是封装了一个AlertDialog的基类。
大家可以根据自己实际项目的需要，仿照CommonDialog实现一个。
BaseDialog
abstract class BaseDialog<T : BaseDialogBuilder<*, *>>(context: Context, style: Int) : AlertDialog(context, style), BaseDialogInterface {

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

initDialog()
bindView(savedInstanceState)
}
open fun initDialog() {
window?.let {
var params = it.attributes
params.gravity = dialogBuilder.gravity
params.width = dialogBuilder.width
params.height = dialogBuilder.height
if (dialogBuilder.animStyle != 0) it.setWindowAnimations(dialogBuilder.animStyle)
if (dialogBuilder.dimAmount in 0.0..1.0) params.dimAmount = dialogBuilder.dimAmount
it.attributes = params
}
}
abstract fun bindView(saveInstanceState: Bundle?)
abstract fun setContentView(): Int
