新しいアプリケーションで StaggeredGridView を使用しようとしています。すべてが正常に機能しています。ここで、HeaderView と FooterView を追加したいのですが、これにより次のエラーが発生します。
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.

アクティビティの onCreate に onExecute メソッドを持つ AsynchTask の onPostExecute メソッドにアダプタを設定しました。また、AsynchTask を開始する前に、onCreateMethod に Header と FooterView を追加します。
また、runOnUiThread から実行しようとしましたが、UI スレッドにいる場合は Looper.myLooper() == Looper.getMainLooper() で確認しました。この問題を解決する方法のヒントを持っている人。
