How To Design Screens In An App
Prerequisites: How to Create a Splash Screen in Android using Kotlin?
Android Splash Screen is the first screen visible to the user when the application's launched. Splash Screen is the user's first experience with the application that's why it is considered to be one of the most vital screens in the application. It is used to display some information about the company logo, company name, etc. We can also add some animations to the Splash screen as well. In this article, we will be making an animated Splash Screen Using Kotlin.A sample GIF is given below to get an idea about what we are going to do in this article.

Steps to Create an Animated Splash Screen
Step 1: Create a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Kotlin as the programming language.
Step 2: Create an animation file
To create an animation file in android studio please follow the given instructions carefully. Go to the app > res > right-click > New > Android Resource Directory.
Then name the directory name as anim. And then click on OK.
Go to the anim > right-click > New > Animation Resource File
And name the file name as side_slide and click on OK.
Now add this code to the animated XML file. Below is the code for the side_slide.xml file.
XML
<? xml version = "1.0" encoding = "utf-8" ?>
< set
< translate
android:duration = "1500"
android:fromXDelta = "-50%"
android:fromYDelta = "0%" />
< alpha
android:duration = "1500"
android:fromAlpha = "0.1"
android:toAlpha = "1.0" />
</ set >
Step 3: Create another activity
Go to app > java > first package name > right-click > New > Activity > Empty Activity and create another activity and named it as SplashScreen. Edit the activity_splash_screen.xml file and add image, text in the splash screen as per the requirement. Here we are adding an image to the splash screen. Below is the code for the activity_splash_screen.xml file.
XML
<? xml version = "1.0" encoding = "utf-8" ?>
< androidx.constraintlayout.widget.ConstraintLayout
android:layout_width = "match_parent"
android:layout_height = "match_parent"
android:background = "#fff"
tools:context = ".SplashScreen" >
< ImageView
android:id = "@+id/SplashScreenImage"
android:layout_width = "300dp"
android:layout_height = "200dp"
android:src = "@drawable/geeksforgeeks"
app:layout_constraintBottom_toBottomOf = "parent"
app:layout_constraintLeft_toLeftOf = "parent"
app:layout_constraintRight_toRightOf = "parent"
app:layout_constraintTop_toTopOf = "parent" />
</ androidx.constraintlayout.widget.ConstraintLayout >
Go to the SplashScreen.kt file, and refer to the following code. Below is the code for the SplashScreen.kt file. Comments are added inside the code to understand the code in more detail.
Kotlin
import android.content.Intent
import android.os.Bundle
import android.os.Handler
import android.view.WindowManager
import android.view.animation.AnimationUtils
import android.widget.ImageView
import androidx.appcompat.app.AppCompatActivity
@Suppress ( "DEPRECATION" )
class SplashScreen : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super .onCreate(savedInstanceState)
setContentView(R.layout.activity_splash_screen)
window.setFlags(
WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN
)
val backgroundImage: ImageView = findViewById(R.id.SplashScreenImage)
val slideAnimation = AnimationUtils.loadAnimation( this , R.anim.side_slide)
backgroundImage.startAnimation(slideAnimation)
Handler().postDelayed({
val intent = Intent( this , MainActivity:: class .java)
startActivity(intent)
finish()
}, 3000 )
}
}
Step 4: Working with the AndroidMenifest.xml file
Go to the AndroidMenifest.xml file and add the following code in the Splash Screen Activity. This is used to hide the status bar or action bar.
android:theme="@style/Theme.AppCompat.Light.NoActionBar"
Also, add <intent-filter> inside the Splash Screen Activity to make this activity as the starting activity. So whenever the app will execute the user can see the splash screen at the beginning. Below is the complete code for the AndroidMenifest.xml file.
XML
<? xml version = "1.0" encoding = "utf-8" ?>
package = "com.example.animatedsplashscreen" >
< application
android:allowBackup = "true"
android:icon = "@mipmap/ic_launcher"
android:label = "@string/app_name"
android:roundIcon = "@mipmap/ic_launcher_round"
android:supportsRtl = "true"
android:theme = "@style/AppTheme" >
< activity android:name = ".MainActivity" ></ activity >
< activity
android:name = ".SplashScreen"
android:theme = "@style/Theme.AppCompat.Light.NoActionBar" >
< intent-filter >
< action android:name = "android.intent.action.MAIN" />
< category android:name = "android.intent.category.LAUNCHER" />
</ intent-filter >
</ activity >
</ application >
</ manifest >
Step 5: Working with the activity_main.xml file
Go to the activity_main.xml file and add a text which will show "Welcome to GeeksforGeeks" when the user will enter into the MainActivity. Below is the code for the activity_main.xml file.
XML
<? xml version = "1.0" encoding = "utf-8" ?>
< androidx.constraintlayout.widget.ConstraintLayout
android:layout_width = "match_parent"
android:layout_height = "match_parent"
android:background = "#000"
tools:context = ".MainActivity" >
< TextView
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:text = "Welcome To GeeksforGeeks"
android:textColor = "@color/colorAccent"
android:textSize = "20dp"
app:layout_constraintBottom_toBottomOf = "parent"
app:layout_constraintLeft_toLeftOf = "parent"
app:layout_constraintRight_toRightOf = "parent"
app:layout_constraintTop_toTopOf = "parent" />
</ androidx.constraintlayout.widget.ConstraintLayout >
Step 6: Working with the MainActivity.kt file
Do nothing in the MainActivity.kt file as we already created a new activity for the Splash Screen. Below is the code for the MainActivity.kt file
Kotlin
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.widget.Toast
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super .onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
}
