仿ios各种对话框实现，妈妈再也不用担心了

自定义Dialog的实现

版权声明：本文为博主原创文章，未经博主允许不得转载。

• 首先呢这个需求很普遍，在开发中几乎每个项目都会用到，也比较简单，嘎嘎，博主的 处女作哦，较菜谅解。：

• 让我们来想想一个Dialog它需要写什么呢？

• 1. 内容几乎是必不可少的了

• 2.我们也有能用到标题，标题也有可能附带图标

• 3.也有可能我们需求比较不普通的内容，用不到我们预先的内容显示的控件，直接addView形式展示内容

• 4.最后一步当然是我们两个按钮的点击事件的回调了

• 好了，bb了这么就 ，下面直接开车了

首先上一张效果图，这是我看ios效果仿了一下

接下来就是代码实现了

public class BaseDialog extends Dialog {

    public BaseDialog(Context context) {
        super(context);
    }

    public BaseDialog(Context context, int themeResId) {
        super(context, themeResId);
    }

    protected BaseDialog(Context context, boolean cancelable, OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
    }

        private int Image = 0;

        private DialogInterface.OnClickListener
                positiveButtonClickListener,
                negativeButtonClickListener;

以上就是主要全部代码的实现了，博主初入android，所以嘿嘿嘿，基本都是比较简单的东西啦，就不做解释了，这里顺便贴一下布局的实现

到这里就差不多结束了 drawable这里就不贴了，我瞅瞅demo怎么上传把

另外需要学习小伙伴可以加群！大家一起讨论哈哈！一起开车！我在里面只是一个小小的萌新。群号：188089649！转载请注明出处！谢谢！
Demo：仿ios提示弹出框

仿ios各种弹窗实现

下面，介绍一下各种ios弹窗的实现：是借鉴自一位大神的，嘿嘿嘿嘿

这是大神的博客地址，大家可以去看看](http://m.blog.csdn.net/article/details?id=47058159)
话不多说 先开车
先上效果图，本来是想上一直动态图的 ，奈何萌新不会！！！！被我金子一喷，会了。。。
