    在您的资源文件中删除结束标记加上正文，即删除“tv_deviceName”

    <item type="id" name="button_ok">tv_deviceName</item>

    我应该如下所示

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <item type="id" name="button_ok" />
    <item type="id" name="dialog_exit" />
</resources>

    然后，此布局代码段使用Button小部件的“button_ok”ID：

    <Button android:id="@id/button_ok"
    .... />

    请注意，android：id值不包含ID引用中的加号，因为ID已存在，如上面的ids.xml示例中所定义 . （当您使用加号登录为XML资源指定ID时，格式为android：id =“@ id / name” - 这意味着“名称”ID不存在且应该创建 . ）

    作为另一个示例，以下代码段使用“dialog_exit”ID作为对话框的唯一标识符：

    showDialog(R.id.dialog_exit);

    应该：

    <?xml version="1.0" encoding="utf-8"?>
<resources>
    <item name="timebar" type="id"/>
    <item name="textClock" type="id"/>
</resources>

    ref是here .
