推荐答案

对话框

"A dialog是一个小窗口，提示用户做出决定或输入其他信息.对话框不会填满屏幕，通常用于模态事件，要求用户先执行操作他们可以继续."

"A dialog is a small window that prompts the user to make a decision or enter additional information. A dialog does not fill the screen and is normally used for modal events that require users to take an action before they can proceed."

AlertDialog有很多变体，据我所知，您可以在对话框的右上角也有一个十字按钮(您可以在任何位置设置图标，因为您可以提供自定义布局进入AlertDialog).

AlertDialog has many variants and as far as I can assume your problem, You can have a cross button too in the top-right corner of the dialog (You can set the icons anywhere, as you can provide a custom layout to an AlertDialog).

-可以添加任何视图

-易于编辑

-只需修改布局即可适用于横向或纵向的平板电脑或手机

-Can be adapted to tablets or cellphones in landscape or portrait just by modifying the layout

-可以专门设计一个全新的类

-Can dedicate a whole new class just to modify it your way

PopupWindows

此类表示popup window，可用于显示任意视图.弹出窗口是显示在当前活动顶部的浮动容器."

"This class represents a popup window that can be used to display an arbitrary view. The popup window is a floating container that appears on top of the current activity."

PopupWindow是另一个可自定义屏幕上任意位置的自定义弹出窗口的工具.如果您总是在屏幕中间显示此弹出窗口，那么我建议您不要使用此弹出窗口. AlertDialog应该可以正常工作.

PopupWindow is another tool to customize your custom pop up anywhere in the screen. If you're showing this popup always in the middle of the screen, then I would like to suggest not to use this. The AlertDialog should work fine.

-简单

-更易于编码

-这是更标准的，因此用户很难与它混淆

-It's more standard so it'll be harder for the user to be confused with it
