Question

我首先有两个数组用于小时，第二个用于分钟，这是我的数组在string.xml中声明它

   ` <string-array name="feedbacktypelist">
    <item>@string/hr0</item>  
    <item>@string/hr1</item>  
    <item>@string/hr2</item>  

</string-array>

<string-array name="array2">
    <item>@string/min5</item>  
    <item>@string/min10</item>  
    <item>@string/min15</item>  
    <item>@string/min20</item>  
    <item>@string/min25</item>  
    <item>@string/min30</item>
    <item>@string/min35</item>  
    <item>@string/min40</item>  
    <item>@string/min45</item>
    <item>@string/min50</item>  
    <item>@string/min55</item>  
    <item>@string/min59</item>


</string-array>`

这是我在java中的代码

我想： 1-在微调器中检索用户选择它的项目，而不是位置 2 - 如果用户从spinner1中选择项目“hr02”，则spinner2将禁用

感谢您的帮助，StackOverFlow现在成为您的英雄！：“）

Answer 1

使用此

String str = parent.getSelectedItem().toString();

if(str.equals("hr2")
{
    spinner2.setEnabled(false);  
}

Answer 2

试试这个：

String str = parent.getSelectedItem().toString();
if (str.equals("hr0")){
        //retrieve the item as string
}
if (str.equals("hr1")){
        //retrieve the item as string
}
if (str.equals("hr2")){
        //retrieve the item as string
        //make the 2nd spinner disable
}

从Spinner中检索项目并放置一些条件
