The intent of this guide is to give you an idea about the Android development landscape and to help guide your learning if you are confused. One TextView is placed in the center of the layout file as like below : The Kotlin file of the SecondActivity is SecondActivity.kt and the layout file is activity_second.xml. We are converting the text to String using the toString method. The key is “Data” and the data is the text that the user has entered in the edit text. This method takes data as key-value pairs. We are adding data to this intent object using putExtra method. onButtonClicked method is called if the user clicks on the button.Inside onCreate, we are initializing the editText variable.Here, we have defined one lateinit EditText variable.AppCompatActivityĬlass MainActivity : AppCompatActivity ( ) MainActivity.kt :īelow is the source code for MainActivity.kt : The id of the EditText is editText and the id of the Button is button. On button click, it will invoke the method onButtonClicked in MainActivity.kt. MainActivity.kt is our first activity name and activity_main.xml is its layout file. The second activity will read the data and show it in a TextView. On click, we will start the second Activity and pass the string that was entered in the EditText. The user will enter text in the EditText and click on the button. In this example, we will create one Application with two screens or Activities: the first Activity will hold one EditText and one Button. Optionally, we can set data to an intent. The intent object takes the start activity and destination activity names.
We can use one intent to pass data from one Activity to another Activity, starting service or delivering broadcasts. For passing data in Android, we need to use objects of class Intent. We will use Kotlin and Android Studio in this exercise. In this example, we will learn how to pass data from one Activity to another in Android.
