This article shows how to send data from one activity to the second activity using intent . In this example , we have two activities. Activity_first is source activity, and activity_second which is the destination activity. PutExtra() method works by sending data and receiving using this getStringExtra() of android application.

There are two methods for sending and receiving data.

putExtra(): This method is used to send the data. It's work with key and value.
getStringExtra(): This method is revised data from source activity.

Step-By-Step Implementation

Step 1: Create a new project in Android or you can use an already created project.

Step 2: Create an XML file named acitivity_main_first.xml of the layout folder.

 <?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/idRLContainer"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:orientation="vertical"
	tools:context=".MainActivity">

	<TextView
    	android:id="@+id/txtTitle"
    	android:layout_width="match_parent"
    	android:layout_height="wrap_content"
    	android:layout_margin="10dp"
    	android:layout_marginTop="80dp"
    	android:text="Candidroot solutions"
    	android:textAlignment="center"
    	android:textSize="18sp"
    	app:layout_constraintEnd_toEndOf="parent"
    	app:layout_constraintHorizontal_bias="0.842"
    	app:layout_constraintStart_toStartOf="parent"
    	app:layout_constraintTop_toTopOf="parent" />

	<EditText
    	android:id="@+id/editText"
    	android:layout_width="0dp"
    	android:layout_height="wrap_content"
    	android:layout_below="@+id/txtTitle"
    	android:layout_marginStart="30dp"
    	android:layout_marginTop="104dp"
    	android:layout_marginEnd="30dp"
    	android:hint="Typing...."
    	app:layout_constraintEnd_toEndOf="parent"
    	app:layout_constraintStart_toStartOf="parent"
    	app:layout_constraintTop_toBottomOf="@+id/txtTitle" />

	<Button
    	android:id="@+id/btnsubmit"
    	android:layout_width="wrap_content"
    	android:layout_height="wrap_content"
    	android:layout_marginTop="76dp"
    	android:text="submit"
    	app:layout_constraintEnd_toEndOf="parent"
    	app:layout_constraintHorizontal_bias="0.498"
    	app:layout_constraintStart_toStartOf="parent"
    	app:layout_constraintTop_toBottomOf="@+id/editText" />


 </androidx.constraintlayout.widget.ConstraintLayout>

Step 3: Create a kt file named AcitivityMainFirst.kt of the layout folder.

 import android.content.Intent
 import android.os.Bundle
 import android.view.View
 import android.widget.Button
 import android.widget.EditText
 mport androidx.activity.enableEdgeToEdge
 import androidx.appcompat.app.AppCompatActivity


 class AcitivityMainFirst : AppCompatActivity() {

	
	private var send_button: Button? = null
	private var send_text: EditText? = null
	override fun onCreate(savedInstanceState: Bundle?) {
    	super.onCreate(savedInstanceState)
    	setContentView(R.layout.activity_main_activityone)
    	
    	//assign object of components
    	send_button = findViewById(R.id.btnsubmit)
    	send_text = findViewById(R.id.editText)

    	//set click listener of button
    	send_button?.setOnClickListener { v: View? ->
        	val str = send_text?.getText().toString()
        	//create object of intent
        	val intent = Intent(
            	applicationContext,
            	MainActivitySecond::class.java
        	)
        	//pass data set here
        	intent.putExtra("receiverdata", str)
        	startActivity(intent)
      	}
	}
 }

Step 4: Create an XML file named acitivity_main_second.xml of the layout folder.

 <?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/idRLContainer"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:orientation="vertical"
	tools:context=".MainActivity">

	<TextView
    	android:id="@+id/txtTitle"
    	android:layout_width="match_parent"
    	android:layout_height="wrap_content"
    	android:layout_margin="10dp"
    	android:layout_marginTop="80dp"
    	android:text="Candidroot solutions"
    	android:textAlignment="center"
    	android:textSize="18sp"
    	app:layout_constraintEnd_toEndOf="parent"
    	app:layout_constraintHorizontal_bias="0.842"
    	app:layout_constraintStart_toStartOf="parent"
    	app:layout_constraintTop_toTopOf="parent" />
	
	<TextView
    	android:id="@+id/txtData"
    	android:layout_width="0dp"
    	android:layout_height="wrap_content"
    	android:layout_below="@+id/txtTitle"
    	android:layout_marginStart="30dp"
    	android:layout_marginTop="104dp"
    	android:layout_marginEnd="30dp"
    	android:textStyle="bold"
    	app:layout_constraintEnd_toEndOf="parent"
    	app:layout_constraintStart_toStartOf="parent"
    	app:layout_constraintTop_toBottomOf="@+id/txtTitle" />

 </androidx.constraintlayout.widget.ConstraintLayout>

Step 5: Create a kt file named AcitivityMainSecond.kt.xml of the layout folder.


 import android.annotation.SuppressLint
 import android.os.Bundle
 import android.widget.TextView
 import androidx.activity.enableEdgeToEdge
 import androidx.appcompat.app.AppCompatActivity


 class MainActivityTwo : AppCompatActivity() {
	var receiverdatat: TextView? = null
	@SuppressLint("MissingInflatedId")
	override fun onCreate(savedInstanceState: Bundle?) {
    	super.onCreate(savedInstanceState)
    	enableEdgeToEdge()
    	setContentView(R.layout.activity_main_two)
    	receiverdatat = findViewById(R.id.txtData)
    	val intent = intent
    	val str = intent.getStringExtra("receiverdatat")
    	receiverdatat?.setText(str)
 	}
 }

Step 5: Output of above example

Happy coding!
