I am having error on every support design widget. Like the recyclerview, coordinator layout etc. Everytime, I add a support design widget it is showing

java.lang.ClassNotFoundException: android.view.View$OnUnhandledKeyEventListener

on layout issue section. I'm using api 28.0.0-rc01, gradle 4.4 android 3.1.4. Here, is my build.gradle (app) file

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 28

}

Here is my layout file

I have checked the View class file, but the "OnUnhandledKeyEventListener" was in there. Don't know why this problem is occurring. Please, tell me how to solve this problem.

Open styles.xml in app > src > main > res > values folder and change this line

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

to

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

android - OnUnhandledKeyEventListener class not found, Open styles.xml in app > src > main > res > values folder and change this line <​style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">. to OnUnhandledKeyEventListener class not found (3 answers) Closed 3 months ago. i was using android support v7 recyclerView in my xml layout file in android

Currently there is no workaround unfortunately. android.support.v4.view.ViewCompat does not implement View.OnUnhandledKeyEventListener in the androidx package. The bug has been submitted here.

Didn't find class "android.view.View , Rejecting re-init on previously-failed class java.lang.Class : java.lang. Didn't find class "android.view.View$OnUnhandledKeyEventListener" #295.

Steps

  1. add this to gradle implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
  2. implementation 'com.android.support:design:28.0.0-alpha1' same version as above.
  3. style.xml

I was going crazy trying to fix this issue. Seriously, thanks a lot! I did have one small problem with this, though. My complilation failed and I got this message:

Comments
  • How did you solved that? Please add an answer. I'm having the same problem.
  • I have solved this problem by updating my api from "com.android.support:appcompat-v7:28.0.0-rc01" to "androidx.appcompat:appcompat:1.0.2"
  • Well, I only realized that this "error" is just a warning this after asking here. This message doesn't do anything to the app itself, but I just got stuck looking for this while another error (on code) was happening. Thanks anyway.
  • Possible duplicate of android/view/view$onUnhandledKeyEventListener (onMeasure error)
  • You need to Clean the project and remove the build folder then it works
  • Hi, welcome to stackoverflow. Can you please edit your answer and format it to make it readable? It also looks truncated. Can you finish it?
