Here is an example of lint warnings produced by this check:

src/test/pkg/MyActivity.kt:15:Error: @layout/activity_main does not
contain a declaration with id text_field [MissingInflatedId]
    requireViewById<EditText>(R.id.text_field).isEnabled = false
                              ---------------
src/test/pkg/MyActivity.kt:21:Error: @layout/list_item does not contain
a declaration with id image_view [MissingInflatedId]
    val imgView = rootView.findViewById<ImageView>(R.id.image_view)
                                                   ---------------

Here are the relevant source files:

src/test/pkg/MyActivity.kt:

package test.pkg

import android.app.Activity
import android.graphics.ColorFilter
import android.os.Bundle
import android.view.View
import android.widget.EditText
import android.widget.ImageView

class MyActivity : Activity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        // Error: @id/text_field is not in @layout/activity_main
        requireViewById<edittext>(R.id.text_field).isEnabled = false
    }

    fun createListItem(filter: ColorFilter): View {
        val rootView = layoutInflater.inflate(R.layout.list_item, null)
        // Error: @id/image_view is not in @layout/list_item
        val imgView = rootView.findViewById<imageview>(R.id.image_view)
        imgView.colorFilter = filter
        return rootView
    }
}

res/layout/activity_main.xml:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent" />

res/layout/list_item.xml:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent" />

test.pkg:

@id/text_field

You can also visit the source code for the unit tests for this check to see additional scenarios.

You can suppress false positives using one of the following mechanisms:

• Using a special lint.xml file in the source tree which turns off the check in that folder and any sub folder. A simple file might look like this:

  <?xml version="1.0" encoding="UTF-8"?>
  <lint>
      <issue id="MissingInflatedId" severity="ignore" />
  </lint>

  Instead of ignore you can also change the severity here, for example from error to warning. You can find additional documentation on how to filter issues by path, regular expression and so on here.

• In Gradle projects, using the DSL syntax to configure lint. For example, you can use something like

  lintOptions {
      disable 'MissingInflatedId'
  }

  In Android projects this should be nested inside an android { } block.

• For manual invocations of lint, using the --ignore flag:

  $ lint --ignore MissingInflatedId ...`

• Last, but not least, using baselines, as discussed here.
