java - 在 addHeaderView 和 addFooterView 之后设置 StaggeredGridView setAdapter

Question

我尝试在我的新应用程序中使用 StaggeredGridView。一切正常。现在我想添加一个 HeaderView 和一个 FooterView，但这给了我以下错误:

java.lang.IllegalStateException: The content of the adapter has changed but ExtendableListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. [in ExtendableListView(2131165194, class com.tundem.numbersreloaded.view.NumbersGridView) with Adapter(class com.etsy.android.grid.HeaderViewListAdapter)]

我在 AsynchTask 的 onPostExecute 方法中设置适配器，它在我的 Activity 的 onCreate 中有它的 onExecute 方法。在启动 AsynchTask 之前，我还在 onCreateMethod 中添加了 Header 和 FooterView。

我还尝试从 runOnUiThread 运行它，并且我还通过 Looper.myLooper() == Looper.getMainLooper() 检查了我是否在 UI 线程中。任何有提示我如何解决这个问题的人。

Answer 1

我自己已经找到了答案。

这不是我一直遇到的问题。这是 AndroidStaggeredGrid 当前存在的问题。已经有一个带有修复的合并 Pull-Request，但它还没有上传到 Maven。

我指的是这两个提交:

• https://github.com/etsy/AndroidStaggeredGrid/commit/18e9ae8251ff30ae29125613c8fd909e5e8c27a6

• https://github.com/etsy/AndroidStaggeredGrid/commit/2fce475c197bb18871d2a1076e259a57d8513104

目前的解决方案是自己构建库并将其发布到私有(private) Maven 存储库，或者将项目作为库项目包含在内!
