Data Binding in Android with Example
Last Updated : 18 Feb, 2025
In Android, the Data Binding Library is a support library that allows you to bind UI components in your layouts to data sources in your app using a declarative format rather than programmatically.
Step by Step Implementation:
Step 1: Create a New Project
If you don’t know how to create a new project in Android Studio then you can refer to How to Create/Start a New Project in Android Studio?
Step 2: Enable Data Binding
Navigate to Gradle Scripts > build.gradle.kts(module level).
Add the below code snippet to the build.gradle.kts (module level) file under the android{} scope to activate Data Binding in the application:
buildFeatures {
dataBinding = true
}Step 3: Create a model class
Navigate app > kotlin+java > {package-name}. Right click on it and go to New > Kotlin Class/File or Java Class. Set the name Company for the file. Add the following code to the file.
Company.java package org.geeksforgeeks.demo; public class Company { private String name; private String website; public Company(String name, String website) { this.name = name; this.website = website; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getWebsite() { return website; } public void setWebsite(String website) { this.website = website; } } package org.geeksforgeeks.demo data class Company ( val name: String, val website: String )
Step 4: Working on activity_main.xml
Navigate to the app > res > layout > activity_main.xml and add the below code to that file.
activity_main.xml:
activity_main.xml <layout 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"> <data> <variable name="company" type="org.geeksforgeeks.demo.Company" /> </data> <androidx.constraintlayout.widget.ConstraintLayout android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <TextView android:id="@+id/name" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="32dp" android:text="@{company.name}" android:textSize="24sp" app:layout_constraintBottom_toTopOf="@+id/website" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" app:layout_constraintVertical_chainStyle="packed" /> <TextView android:id="@+id/website" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@{company.website}" android:textSize="24sp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/name" /> </androidx.constraintlayout.widget.ConstraintLayout> </layout> Step 5: Working on Main Activity file
Navigate to the MainActivity.java/MainActivity.kt file and use the following code in it. Comments are added to the code to have a better understanding.
MainActivity.java package org.geeksforgeeks.demo; import android.os.Bundle; import androidx.appcompat.app.AppCompatActivity; import androidx.databinding.DataBindingUtil; import org.geeksforgeeks.demo.databinding.ActivityMainBinding; public class MainActivity extends AppCompatActivity { private ActivityMainBinding binding; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Setting up Data Binding binding = DataBindingUtil.setContentView(this, R.layout.activity_main); // Creating Company object and binding it to the layout Company company = new Company("GeeksforGeeks", "www.geeksforgeeks.org"); binding.setCompany(company); } } package org.geeksforgeeks.demo import android.os.Bundle import androidx.appcompat.app.AppCompatActivity import androidx.databinding.DataBindingUtil import org.geeksforgeeks.demo.databinding.ActivityMainBinding class MainActivity : AppCompatActivity() { private lateinit var binding: ActivityMainBinding override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) binding = DataBindingUtil.setContentView(this, R.layout.activity_main) val company = Company("GeeksforGeeks", "www.geeksforgeeks.org") binding.company = company } } Output:
