私はメソッドdisplayDialogを使用しています...それは機能しますが、Eclipseはこれに関する警告を表示します：
showDialog(showRetry ? 1 : 0);
方法：
private void displayDialog(final boolean showRetry) {
mHandler.post(new Runnable() {
public void run() {
setProgressBarIndeterminateVisibility(false);
showDialog(showRetry ? 1 : 0);
}
});
}
検索私は、問題を回避するために使用できるFragmentManagerがあることを確認した同様の質問を見つけましたが、FroyoおよびGingerBreadとのレトロ互換性を維持しながら、特定のシナリオで問題を修正するためにどのように使用できるかわかりません。
私たちを手伝ってくれますか？
