Answer 1

我通过在 onResume() 中移动代码自己解决了我的问题

@Override
        protected void onResume() {
            super.onResume();

            tg1pref = preferences.getBoolean("tg1pref", true);
            if (tg1pref) {
                toggleMap.setChecked(true);
            } else {
                toggleMap.setChecked(false);
            }
        }

Answer 2

tg1pref = preferences.getBoolean("tg1pref", true);

在上面的行中使用false而不是 true。那应该行得通。
