AppCompatDialogFragment自定义模态弹框
很多时候系统自带的AlertDialog并不能满足我们模态弹框的需求，我们的app具体业务可能需要定制化的模态弹框，这个时候我们可以通过继承AppCompatDialogFragment来定制化开发我们需要的模态弹框。
现在大家看看威哥在威哥开发的《妙生活自助称重》App上的继承自AppCompatDialogFrament的定制化弹框效果图：
童鞋们，怎么样？威哥做出来的效果还不错吧。
废话少说，直接上代码，和大家一起分享分享，之后大家就可以自行动手了：
1.xml布局（addfruit_dialog_layout.xml）：
2、自定义弹框java类：
