资源文件

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

建立环境

• Android Studio 3.1.4
• minSdkVersion = 21
• targetSdkVersion = 28
• compileSdkVersion = 28
• buildToolsVersion ="28.0.2"

Answer 1

在资源中声明id时,正文应为空

<item
    type="id"
    name="id_name" />

欲了解更多信息,请查看以下链接

https://developer.android.com/guide/topics/resources/more-resources#Id

正如Oliver Manyasa所说,它应该如下所示

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

Answer 2

升级到Android Studio 3.2.1后,我遇到了类似的问题

该错误指向ids.xml文件中的此项

<item name="mnuActivate" type="id">Activation</item>

正如用户Sangeet Suresh所说,我把它改成了

<item name="mnuActivate" type="id" />

这解决了这个问题.

Answer 3

对于仍在为此寻求解决方案的所有其他人,请在src/main/res/values中创建ids.xml

现在Android Studio将为您提供显式值的错误,如果这些值来自您正在使用的某些库,那么您无法在中间文件中进行更改,因此在此处进行更改并在合并代码时Android Studio负责处理它.

Answer 4

在您的资源文件中删除结束标记加上正文即删除"tv_deviceName"

并让你的资源文件像:

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