Android：从aleetdialog中的按钮打开alertdialog时失败
[英]Android : Fail while openning an alertdialog from a button inside an aleetdialog
问题描述
I want an alertDialog ( with editText and spinner inside) to add some data in a database. 
我想要一个alertDialog（内部带有editText和spinner）在数据库中添加一些数据。 I added some "new" button next to the spinner if the user wants to add a value that isn't in the spinner. 如果用户想要添加不在微调器中的值，则在微调器旁边添加了一些“新”按钮。 This should open a new alertDialog with custom fields related to a new table. 这将打开一个新的alertDialog，其中包含与新表相关的自定义字段。 Everything works exept the show() method inside the onClick() of my "new" button. 一切正常，而我的“新建”按钮的onClick（）中的show（）方法除外。 My code : 我的代码：

You use dialogView for both alert dialogs. 您对两个警报对话框都使用dialogView 。 I think this is the problem. 我认为这是问题所在。
The first dialog sets the dialogView 's parent. 第一个对话框设置dialogView的父级。 When you try to create the second dialog the dialogView already has a parent. 当您尝试创建第二个对话框时， dialogView已经有一个父级。
Create a different dialogView for the 2nd dialog. 为第二个对话框创建一个不同的dialogView 。
