StaggeredGridView setAdapter addHeaderView和addFooterView之後

Question

我嘗試在我的新應用程序中使用StaggeredGridView。一切工作正常。現在我想添加一個HeaderView和FooterView，但是這給了我以下錯誤：

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)]

我設定的適配器中，有它在我的活動的OnCreate onExecute方法的AsynchTask的onPostExecute方法。 在我開始AsynchTask之前，我還在onCreateMethod中添加了Header和FooterView。我也嘗試從runOnUiThread運行它，我也通過Looper.myLooper（）== Looper.getMainLooper（）檢查，如果我在UI線程中。任何人提示我如何解決這個問題。

Answer 1

我發現答案已經在我自己的。

這不是我一直以來的問題。這是AndroidStaggeredGrid目前的問題。 已經有一個合併的Pull-Request，但沒有上傳到maven。

我指的是那些兩次提交：

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

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

對於現在的解決方案是建立在自己的圖書館，將其發佈到私人maven回購，或者您將該項目作爲圖書館項目加入！

Answer 2

您是否嘗試過在您的AsyncTask的onPostExecute方法中調用adapter.notifiyDataSetChanged（）？

這個順序是爲我工作：

• 添加頁眉和頁腳視圖在onCreate方法，然後設置適配器，然後執行異步任務
• 在你的AsyncTask的onPostExecute方法添加的所有項目到你的適配器（addAll或添加取決於SDK版本），並調用adapter.notifyDataSetChanged（）
