Cannot resolve method 'inflate' in 'DashboardActivity'

This is a simple application. I am using Intent to navigate from activity_main.xml to activity_dashboard.xml In DashboardActivity.java file I am trying to use Data binding property. But I am getting 2 errors

1. Cannot resolve method 'inflate' in 'DashboardActivity'
2. Cannot resolve method 'getRoot' in 'DashboardActivity'

I have made changes in the build.gradle file. Also data binding is working fine in MainActivity.java but not in DashboardActivity.java

1. DashboardActivity.java

package com.example.inclasstask5; import androidx.appcompat.app.AppCompatActivity; import android.content.Context; import android.content.SharedPreferences; import android.os.Bundle; import android.view.View; import android.widget.TextView; import com.example.inclasstask5.databinding.ActivityDashboardBinding; public class DashboardActivity extends AppCompatActivity { SharedPreferences sharedPref; TextView enteredData; DashboardActivity binding; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); binding = DashboardActivity.inflate(getLayoutInflater()); View view1 = binding.getRoot(); setContentView(view1); // setContentView(R.layout.activity_dashboard); sharedPref = getSharedPreferences("login_Details", Context.MODE_PRIVATE); enteredData = findViewById(R.id.textView2); init(); } private void init(){ String username = sharedPref.getString("ID" , "No Username"); enteredData.setText("Login Successfully - " + username); } } 

2. activity_dashboard.xml

<?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/root2" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".DashboardActivity"> <TextView android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginStart="140dp" android:layout_marginTop="115dp" android:text="" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" /> </androidx.constraintlayout.widget.ConstraintLayout> 

1. sync the gradle files again
2. cleared caches
