Issue1：
每当我将setOnPreferenceChangeListener调用onCreate中的引用键后，首选项摘要都会更新，但当我返回上一个活动（主页）并再次返回此活动时，摘要会被删除为先前选择的值存储的选项（如重新创建活动）
Issue2：
我将setOnPreferenceChangeListener设置为EditTextPreference，每当添加新值时，它应更新其首选项摘要，并将首选项摘要设置为已定义的文本（如果此值为0）。问题是每当我放入onCreate中的方法app force关闭。
此外，当我尝试删除onCreate中的方法时，新值不会存储为首选项摘要。
以下是我的代码：
