一、前言：
1、PopupWindow与AlertDialog的区别
最关键的区别是AlertDialog不能指定显示位置，只能默认显示在屏幕最中间（当然也可以通过设置WindowManager参数来改变位置）。而PopupWindow是可以指定显示位置的，随便哪个位置都可以，更加灵活。

效果图如下：https://gitee.com/luoyanyong/PopupWindowDemo

右侧弹出.png
下方弹出.png
上方弹出.png
2、PopupWindow的相关函数
（1）、构造函数：
//方法一：
public PopupWindow (Context context)
//方法二：
public PopupWindow(View contentView)
//方法三：
public PopupWindow(View contentView, int width, int height)
//方法四：
public PopupWindow(View contentView, int width, int height, boolean focusable)
首要注意：看这里有四个构造函数，但要生成一个PopupWindow最基本的三个条件是一定要设置的：View contentView，int width, int height ；少任意一个就不可能弹出来PopupWindow！！！！
所以，如果使用方法一来构造PopupWindow，那完整的构造代码应该是这样的：
View contentView = LayoutInflater.from(MainActivity.this).inflate(R.layout.popuplayout, null);
PopupWindwo popWnd = PopupWindow (context);
popWnd.setContentView(contentView);
popWnd.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT);
popWnd.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
有关为什么一定要设置width和height的原因，我们后面会讲，这里说一下为什么样强制设置contentView；很简单的原因是因为PopupWindow没有默认布局，它不会像AlertDialog那样只setTitle,就能弹出来一个框。PopupWindow是没有默认布局的，它的布局只有通过我们自己设置才行。由于方法三中，含有了这三个必备条件，不用单独设置contentview或者width、height，所以构造方法三是用的最多的一个构造方法。
最后，方法四中的focusable变量不是必须的，有关它的方法和意义，我们会在下一篇中细讲。
（2）显示函数
显示函数主要使用下面三个：
//相对某个控件的位置（正左下方），无偏移
showAsDropDown(View anchor)：
//相对某个控件的位置，有偏移;xoff表示x轴的偏移，正值表示向左，负值表示向右；yoff表示相对y轴的偏移，正值是向下，负值是向上；
showAsDropDown(View anchor, int xoff, int yoff)：
//相对于父控件的位置（例如正中央Gravity.CENTER，下方Gravity.BOTTOM等），可以设置偏移或无偏移
showAtLocation(View parent, int gravity, int x, int y)：
这里有两种显示方式：
1、显示在某个指定控件的下方
showAsDropDown(View anchor)：
showAsDropDown(View anchor, int xoff, int yoff)；
2、指定父视图，显示在父控件的某个位置（Gravity.TOP,Gravity.RIGHT等）
showAtLocation(View parent, int gravity, int x, int y)；
（3）、其它函数
//关闭弹窗
public void dismiss()
//设置PopupWindow可聚焦
public void setFocusable(boolean focusable)
//设置PopupWindow可触摸
public void setTouchable(boolean touchable)
//设置外部点击退出
public void setOutsideTouchable(boolean touchable)
//设置背景
public void setBackgroundDrawable(Drawable background)
这几个函数里，这篇只会用到dismiss()，用于不需要的时候，将窗体隐藏掉。
二、使用：
下方是自定义一下popupWindow，使用起来更加方便。
