I've tried to change AppCompat to MaterialComponents but it doesn't work. But when I point to LinearLayout tag (parent of com.google.android.material.textfield.TextInputLayout), it shows the error with a red line, and it disappears when I remove LinearLayout tag away. Is there any problem when I use too many LinearLayout stacks up each other?

Answer 1

Did you add material dependency in your app level build.gradle file?

If not you need to add this in your gradle file.

api 'com.google.android.material:material:<VERSION>'

Answer 2

make sure to add the material dependency in your app level build.gradle file and change the

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

to

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