Getting Started

Android ViewFlipper can be defined as below –

ViewFlipper is a widget that are used to switch between views that have been added to it. Only one view is shown at a time. We can also set animations that will be used when view is shown / hidden.

Sr. XML Attributes Description
1 android:autoStart If set true, it will automatically start animating views.
2 android:flipInterval Specifies the time interval after which view will be flipped

1 android:animateLayoutChanges Specifies whether LayoutTransition should run whenever there is any changes in layout
2 android:animationCache Specifies whether layout animations should create a drawing cache for their children.
3 android:clipToPadding Specifies whether the ViewGroup will clip its children and resize (but not clip) any EdgeEffect to its padding, if padding is not zero

Example of Android ViewFlipper Using Kotlin

At first, we will create android application. Then, we will use viewFlipper using kotlin in the application.

1. Creating New Project in Kotlin

Follow steps below to create new project. Please ignore the steps if you have already created the project.

Step Description
1. Open Android Studio.
2. Go to File => New => New Project. Write application name as ViewFlipper. Then, check Include Kotlin Support and click next button.
3. Select minimum SDK you need. However, we have selected 17 as minimum SDK. Then, click next button
4. Then, select Empty Activity => click next => click finish.
5. You will get a newly created project successfully if you have followed steps properly.

Since we have a project now, we will modify xml and other files to use viewFlipper using kotlin in the application.

2. Modify values folder

Open res/values/strings.xml file. Then, add below code into it.

	<string name="app_name">ViewFlipper</string>
	<string name="pause">Pause</string>
	<string name="play">Play</string>
	<string name="flipping_started">Flipping Started...</string>
	<string name="flipping_stopped">Flipping Stopped...</string>

3. Download Drawable Resources Needed

You need some images, stored in res/drawable folder, that will be used in viewFlipper in the application. You can click here to download images used in the application.

4. Use ViewFlipper Widget in xml file

Open src/main/res/layout/activity_main.xml file and add below code into it.

<?xml version="1.0" encoding="utf-8"?>




In activity_main.xml file, we have defined viewFlipper. Attribute android:autoStart=”” is used to set whether viewFlipper should start flipping the view automatically or not. If set true, it means it will start automatically. Attribute android:flipInterval=”” is used to set the time interval after which view will be flipped.

5. Access ViewFlipper Using Kotlin file

Open src/main/java/com.tutorialwing.viewflipper/MainActivity.kt file and add below code into it.

package com.tutorialwing.viewflipper

import android.os.Bundle
import android.view.Gravity
import android.view.ViewGroup
import android.widget.*

class MainActivity : AppCompatActivity() {

    private var imageList = intArrayOf(R.drawable.guava, R.drawable.jackfruit, R.drawable.mix_fruit, R.drawable.pomegranate, R.drawable.strawberry, R.drawable.zespri_kiwi)

    override fun onCreate(savedInstanceState: Bundle?) {

        val viewFlipper = findViewById<ViewFlipper>(
        if (viewFlipper != null) {
            viewFlipper.setInAnimation(applicationContext, android.R.anim.slide_in_left)
            viewFlipper.setOutAnimation(applicationContext, android.R.anim.slide_out_right)

        if (viewFlipper != null) {
            for (image in imageList) {
                val imageView = ImageView(this)
                val layoutParams = FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)
                layoutParams.setMargins(30, 30, 30, 30)
                layoutParams.gravity = Gravity.CENTER
                imageView.layoutParams = layoutParams

        val btnPlayPause = findViewById<Button>(
        if (btnPlayPause != null && viewFlipper != null) {
            btnPlayPause.setOnClickListener {
                if (viewFlipper.isFlipping)

                btnPlayPause.text = getString(if (viewFlipper.isFlipping) R.string.pause else
                Toast.makeText(this@MainActivity, getString(if (viewFlipper.isFlipping) R.string.flipping_started else R.string.flipping_stopped), Toast.LENGTH_SHORT).show()

We have accessed viewFlipper using kotlin file (i.e. in MainActivity.kt file) in the application. Then, we have set in and out animations in it. in and out animations are used when view is shown or hidden. After that, we have created ImageView that have been added to viewFlipper. Number of imageView created are equal to length of imageList. After that, we have set click listener on viewFlipper that play/pause view flipping in viewFlipper. We have also showing a toast message that displays the current status of the viewFlipper (whether viewFlipper is flipping the view or not).

Since AndroidManifest.xml file is very important in any android application, we are also going to see the content inside this file.

AndroidManifest.xml file

Code inside main/AndroidManifest.xml file is as below.

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.viewflipper"

		<activity android:name=".MainActivity">
				<action android:name="android.intent.action.MAIN"/>

				<category android:name="android.intent.category.LAUNCHER"/>


When we run the program, we will get output as shown above.

That’s end of our tutorial on Android ViewFlipper using Kotlin.
