你现在怎么做？

我希望你理解我,我希望你能帮助我.

这是我想要保存和加载东西的代码：

@OverrIDe        public boolean onCreateOptionsMenu(Menu menu) {        menu.add(2, MENU_SAVE, 2, "Save");        menu.add(3, MENU_LOAD, 3, "Load");        return true;    }    @OverrIDe    public boolean onoptionsItemSelected(MenuItem item) {        switch (item.getItemID()) {    case MENU_SAVE:        Here save the checkBoxes        return true;    case MENU_LOAD:        Here load the checkBoxes    return true;

@R_502_6120@:

SharedPreferences怎么样？您可以以键：值格式存储和加载复选框的状态和名称. How to use.
E. g.这样的事情：

// Init SharedPreferences settings = getSharedPreferences("mysettings", 0);SharedPreferences.Editor editor = settings.edit();// Saveboolean checkBoxValue = v42.isChecked();                editor.putBoolean("v42", checkBoxValue);        editor.commit();;// Loadv42.setChecked(settings.getBoolean("v42", false));

但是,您应该实现更有效的方法,可能是通过所有复选框循环读取其名称或ID,您可以在离开活动之前调用它.
