ViewGroup.java AddViewInner问题 [英] ViewGroup.java AddViewInner issue

问题描述

我一直在追随错误，基本上是相同的错误，但是总是在不同的行上发生

i keep getting following errors, it's basically same error but keeps occuring on different lines

致命异常:java.lang.IllegalStateException:指定的子代已经有一个父代.您必须先在孩子的父母上调用removeView(). 在android.view.ViewGroup.addViewInner(ViewGroup.java:3883)

Fatal Exception: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first. at android.view.ViewGroup.addViewInner(ViewGroup.java:3883)

致命异常:java.lang.IllegalStateException:指定的子代已经有一个父代.您必须先在孩子的父母上调用removeView(). 在android.view.ViewGroup.addViewInner(ViewGroup.java:4312)

Fatal Exception: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first. at android.view.ViewGroup.addViewInner(ViewGroup.java:4312)

致命异常:java.lang.IllegalStateException:指定的子代已经有一个父代.您必须先在孩子的父母上调用removeView(). 在android.view.ViewGroup.addViewInner(ViewGroup.java:4310)

我尝试过的事情:-

• 在添加任何片段的同时，我将此代码添加到onCreateView

• while adding any fragment i add this code in onCreateView

((ViewGroup)view.getParent()).removeView(view); view = inflater.inflate(R.layout.create_carpool_layout，container，false); 返回视图；

((ViewGroup) view.getParent()).removeView(view); view = inflater.inflate(R.layout.create_carpool_layout, container, false); return view;

然后扩大视图

在适配器中扩大布局/视图的同时，我还确保将视图从父视图中移除

While inflating layouts / views in adapter also i make sure the view is removed from parent view

我不确定是什么原因导致了此问题

I am not sure what is causing this problem

推荐答案

尝试仔细检查一下如何放大视图.

Try double checking how you are inflating the view.

有两种可能的方法:

1. 将父项传递给充气机:

1. Passing the parent to the inflater:

LayoutInflater.from(context).inflate(R.layout.layout, this, true);

保留没有父视图的视图:

Keep the view without the parent:

LayoutInflater.from(context).inflate(R.layout.layout, null);

使用第一种方法时，不能使用view作为参数调用addView().
使用第二种方法，视图未固定到父视图，因此您可以调用addView()

When using the first method, you cannot call addView() with the view as parameter.
Using the second way, the view is not pinned to parent, therefore you can invoke addView()
