We have recently published 100+ articles on android tutorials with kotlin and java. If you need, you may visit Android Tutorial for beginners page. You can also check Kotlin Tutorial for beginners. Also, if you are interested in content writing, you can mail us at tutorialwing@gmail.com.Hello Readers! In this post, we are going to learn about android viewSwitcher using kotlin in any android application. We will also learn about different attributes of android viewSwitcher that can be used to customise this widget.

Example of Android ViewSwitcher Using Kotlin
At first, we will create android application. Then, we will use ViewSwitcher 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 ViewSwitcher. 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 viewSwitcher using kotlin in the application.
2. Modify values folder
Open res/values/strings.xml file. Then, add below code into it.
<resources> <string name="app_name">ViewSwitcher</string> <string name="next">Next</string> <string name="no_image">No Image</string> </resources>
3. Download Drawable Resources Needed
You may need images, stored in res/drawable folder, that are needed in the application. These drawable images will be used by viewSwitcher in the application.
4. Use ViewSwitcher 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"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <Button android:id="@+id/btnNext" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_margin="20dp" android:text="@string/next"/> <ViewSwitcher android:id="@+id/viewFlipper" android:layout_width="match_parent" android:layout_height="wrap_content"> <ImageView android:id="@+id/image1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:contentDescription="@string/no_image" android:src="@drawable/pomegranate"/> <ImageView android:id="@+id/image2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:contentDescription="@string/no_image" android:src="@drawable/zespri_kiwi"/> </ViewSwitcher> </LinearLayout>
In activity_main.xml file, we have defined ViewSwitcher widget. Note that there are only two views (i.e. imageView) of viewSwitcher. However, only one view is shown at a time.
5. Access ViewSwitcher Widget in Kotlin file
Open src/main/java/com.tutorialwing.viewswitcher/MainActivity.kt file and add below code into it.
package com.tutorialwing.viewswitcher import android.os.Bundle import android.support.v7.app.AppCompatActivity import android.view.animation.AnimationUtils import android.widget.Button import android.widget.ViewSwitcher class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val viewSwitcher = findViewById<ViewSwitcher>(R.id.viewFlipper) val `in` = AnimationUtils.loadAnimation(this, android.R.anim.slide_in_left) viewSwitcher.inAnimation = `in` val out = AnimationUtils.loadAnimation(this, android.R.anim.slide_out_right) viewSwitcher.outAnimation = out val button = findViewById<Button>(R.id.btnNext) button?.setOnClickListener { viewSwitcher?.showNext() } } }
In MainActivity.java file, we have accessed viewSwitcher widget. Then, we have set in and out animations in it. At last, we have set a click listener to show next view in the viewSwitcher whenever button is clicked.
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.viewswitcher" xmlns:android="http://schemas.android.com/apk/res/android"> <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"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> </application> </manifest>
When we run the program, we will get output as shown above.
That’s end of our tutorial on Android viewSwitcher using Kotlin.
