我有 2 个数组，第一个代表小时，第二个代表分钟，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>`

我想要: 1-检索用户选择的微调器中的项目，而不是位置 2-如果用户从 spinner1 中选择项目“hr02”，则 spinner2 将禁用
感谢您对我的帮助，StackOverFlow 成员(member)现在您是我的英雄! :")
最佳答案
用这个
String str = parent.getSelectedItem().toString();
if(str.equals("hr2")
{
spinner2.setEnabled(false);
}
关于java - 从 Spinner 中检索项目并放置一些条件，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/9514143/
