Android Studio – ActivityBinding Not Recognized

My DetailActivity.java file shows an error by not picking ActivityDetailBinding. Other Activity files are working fine and I put;

buildFeatures{
    viewBinding true
}

in build.gradle file before start working on xml files. Only DetailActivity.java file is showing this error.

Error displaying is;

import com.example.juizeesapp.databinding.ActivityDetailBinding; ^ symbol: class ActivityDetailBinding location: package com.example.juizeesapp.databinding

Please look into this help me through this. TIA.

Here is my code.
