Question

创建聊天应用程序并在创建组时遇到问题（Recycler View的列表项）并通过片段容器对其进行充气。

实际上，有两种观点被夸大了。一个是将在片段容器中膨胀的根视图，另一个是作为Dialog的另一个自定义布局膨胀请求输入组名称。

FAB实现为单击事件以启动Dialog以输入通道名称。第一次单击FAB时，会出现一个对话框，要求输入通道名称来创建组。传递后，创建一个输入组并创建通道/组（Recycler View的列表项）并在容器上膨胀。但是当我第二次单击FAB，重复该过程，创建另一个组/通道时，应用程序崩溃并在logcat上遇到错误。

＆＃34;指定的孩子已经有父母。您必须先在孩子的父母身上调用removeView（）＆＃34; 我不太了解碎片，也不知道这个错误意味着什么。请帮助解决此错误。

谢谢

Answer 1

更改为

radGridView1.FilterDescriptors.Clear();

到

final AlertDialog.Builder b = new AlertDialog.Builder(getActivity());
            b.setView(layout);
            b.show();

尝试改变这样的事情

必须首先在孩子的父母身上调用removeView（）
