In this android example, we will see how to navigate one screen to another screen with Android Intents in Android Studio by Kotlin code.
Implementation:
Create a new Project in android studio.
|
Go to File > New > New Project > Empty Activity > Next > Enter Name > Select Language Kotlin > Finish
|
Go to activity_first.xml file and add the following code
|
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"
android:background="#E8EFA3"
tools:context=".FirstActivity">
<Button
android:id="@+id/btn1"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:text="Go to Second Screen"></Button>
</LinearLayout>
|
Go to FirstActivity.kt file and add the following code
|
val btn1 = findViewById(R.id.btn1)
btn1.setOnClickListener{
val intent = Intent(this, SecondActivity::class.java)
startActivity(intent)
}
|
Create a new empty activity
|
app > java > package name > right-click > New > Activity /Empty Activity > enter name(SecondActivity.kt) > Finish.
|
Add following code in the activity_second.xml file
|
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"
android:background="#A8B80A"
tools:context=".AndroidNavigation.SecondActivity">
<Button
android:id="@+id/btn2"
android:layout_width="300dp"
android:layout_height="wrap_content"
android:text="Go to First Screen"></Button>
</LinearLayout>
|
Open SecondActivity.kt file and add the following code
|
val btn2 = findViewById(R.id.btn2)
btn2.setOnClickListener{
val intent = Intent(this, FirstActivity::class.java)
startActivity(intent)
}
|
By using Intent we wil navigate the activity from first to second screen.
Run the app in your emulator or real device, you will see the following output.
OUTPUT:
Fig. First Screen UI
