【问题描述】：

I have a custom listView of the users installed apps and I want to have a drop down menu with different options such as "alphabatize" or "create custom divider" and when that option is picked, it will rearrange the listView based on通过分隔线的选择。（对于 alphabatize，它会在分隔符上显示 A-Z 并相应地组织等等。）

如何创建可以执行此操作的下拉菜单？

【解决方案1】：

为下拉菜单创建一个 Spinner。覆盖微调器的 onItemSelected()。

spinnerSelectDivider.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id)
    {
        if(position == 0)
        {   
            customListView.setDivider(someDrawableAZ);
        }
        else if(position == 1)
        {
            customListView.setDivider(someDrawableCustom);
        }
    }
}

setDivider 方法的参考。
