[Android] IllegalStateException: Cannot add header view to list : setAdapter has already been called.

Pocket

Android アプリ開発にて、ListFragment で setListAdapter した後に addHeaderView や addFooterView を呼び出すと java.lang.IllegalStateException 例外が発生して、アプリがクラッシュしてしまいます。

Android 4 系だと例外は発生しなくて、Android 2.3 系だと例外でクラッシュするみたいです。

正しいコード

// addHeaderView 後に setListAdapter
listView.addHeaderView(headerView);
listView.addFooterView(footerView);
 
setListAdapter(arrayAdapter);

IllegalStateException でクラッシュするコード

// setListAdapter 後に addHeaderView
setListAdapter(arrayAdapter);
 
listView.addHeaderView(headerView);
listView.addFooterView(footerView);

必ず setListAdapter する前に、addHeaderView や addFooterView を呼び出すようにしましょう。
