Android - Expected Resource of type ID

Solution 1:

This is not a compiler error. It is just editor validation error(lint warning) as this is not a common way to deal with Ids.

So if your app supporting API 17 and higher,

you can call View.generateViewId as

  titleView.setId(View.generateViewId());

and

  sv.setId(View.generateViewId());

and for API<17

1. open your project's res/values/ folder
2. create an xml file called ids.xml

with the following content:

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

then in your code,

  titleView.setId(R.id.titleId);

and

  sv.setId(R.id.svId);

And to disable this warning (If you want)

In Android Studio click on light bulb on line with this 'error'. And select Disable inspection in first submenu.

Solution 2:

You can also disable lint at build.gradle file. Add these lines in your build.gradle file.

android { 
       lintOptions{
             disable "ResourceType"
       }
}
