Question

我正在尝试在片段被销毁之前将值保存在我的首选项中，但是出现一条错误消息

android.support.v4.app.SuperNotCalledException：片段未调用到super.onDestroyView（）

这是我的代码

@Override
public void onDestroyView() {
    pref3.edit().clear().commit();
    for (int i = 0; i < movies1.size(); i++) {
        favouritemovies1.add(movies1.get(i));
        SharedPreferences.Editor editor3 = pref3.edit();
        editor3.putStringSet("favouritemovies", favouritemovies1);
        editor3.commit();
        Toast.makeText(getActivity(), "destroyed", Toast.LENGTH_SHORT).show();
        super.onDestroyView();

    }
}

当我为循环评论时，一切正常！

Answer 1

只需将super.onDestroyView();移出for循环并放在@Override方法内，如下所示：-

   @Override
    public void onDestroyView() {
        // or here 
        pref3.edit().clear().commit();
        for (int i = 0; i < movies1.size(); i++) {
            favouritemovies1.add(movies1.get(i));
            SharedPreferences.Editor editor3 = pref3.edit();
            editor3.putStringSet("favouritemovies", favouritemovies1);
            editor3.commit();
            Toast.makeText(getActivity(), "destroyed", Toast.LENGTH_SHORT).show();

        }
        super.onDestroyView();
    }

解决您的问题。快乐的编码

Answer 2

从循环中删除 super.onDestroyView();并将其写在顶部，如下所示。

@Override
public void onDestroyView() {
    super.onDestroyView();
    pref3.edit().clear().commit();
    for (int i = 0; i < movies1.size(); i++) {
        favouritemovies1.add(movies1.get(i));
        SharedPreferences.Editor editor3 = pref3.edit();
        editor3.putStringSet("favouritemovies", favouritemovies1);
        editor3.commit();
        Toast.makeText(getActivity(), "destroyed", Toast.LENGTH_SHORT).show();


    }
}

希望它对您有帮助。 快乐编码
