SharedPreferences.OnSharedPreferenceChangeListener

SharedPreferences.OnSharedPreferenceChangeListener 用于监听首选项的变化

测试小结论；

我每次写的数值都是1，这个key的值后面没有一直变化，实际不会一直触发onSharedPreferenceChanged

PreferencesUtil.getPreferences().edit().putLong(ExtraName.ORDER_CHANGE, 1).commit();

private SharedPreferences.OnSharedPreferenceChangeListener spChangeListen = new SharedPreferences.OnSharedPreferenceChangeListener() {@Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {if (ExtraName.PHONE_NUM.equals(key)) {setUserInfo();
        } else if (ExtraName.ORDER_CHANGE.equals(key)) {getUserInfoData();
        }}
};
