Input Text in EditText and display it in a second screen

Question

I'm trying to create two screen UI. The first screen has an editText and a Submit button. The second screen has a textView to display text that would be entered in the first screen.

Here is the code I used, but the second screen does not show inputted text from the first screen.

MainActivity.kt [First Screen]:

package com.rishis.testinginputtext

import android.content.Intent
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import com.rishis.testinginputtext.databinding.ActivityMainBinding

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val binding = ActivityMainBinding.inflate(layoutInflater)

        binding.button.setOnClickListener{
            val intent = Intent(this, SecondActivity::class.java)
            startActivity(intent)
        }

        setContentView(binding.root)

    }

}

SecondActivity.kt [Second Screen]:

package com.rishis.testinginputtext

import android.content.Context
import android.os.Bundle
import android.text.Editable
import android.util.AttributeSet
import android.view.View
import android.widget.EditText
import androidx.appcompat.app.AppCompatActivity
import com.rishis.testinginputtext.databinding.ActivityMainBinding
import com.rishis.testinginputtext.databinding.ActivitySecondBinding

class SecondActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        val binding = ActivitySecondBinding.inflate(layoutInflater)
        val oneBinding = ActivityMainBinding.inflate(layoutInflater)
        
        //textView refers to textView in secondActivity
        val textView = binding.textView
        //editText refers to EditText in mainActivity
        val editText = oneBinding.EditText
        
        textView.setText(editText.text.toString())

        setContentView(binding.root)
    }
}

How should I display the text entered in the first screen to be shown in the second screen?

Get the text from `FirstActivity` pass it to the `SecondActivity` through intent. See https://stackoverflow.com/questions/2091465/how-do-i-pass-data-between-activities-in-android-application — Jarnojr, Aug 04 '21 at 00:44

You can use the "putExtra" method to send the data to next activity, and "getExtra" to get the data in next activity.

it's very simple, you just need to use putExtras and getExtra in your activities

your first activity is looks like this:

 val textToPass = editText.text.toString()
 
 binding.button.setOnClickListener{
        val intent = Intent(this, SecondActivity::class.java)
        intent.putExtra("SOME_KEY",textToPass)
        startActivity(intent)
    }

and in a second activity you can get the text by using a getStringExtra and which look like this

 val textToDislplay = intent.getStringExtra("SOME_KEY")
 textView.text = textToDisplay

Input Text in EditText and display it in a second screen
