Greetings!
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 how to use android viewSwitcher programmatically in kotlin in the application. We will also learn how to add viewSwitcher to linearLayout programmatically in android application.

Tutorialwing Kotlin Dynamic ViewSwitcher Output
Getting Started
At first, we will create android project. Then, we will create and use viewSwitcher programmatically in kotlin file.
1. Creating New Project in Kotlin
Follow the steps below to create new project. Please ignore the steps if you have already created a new project.
Step | Description |
---|---|
1. | Open Android Studio. |
2. | Go to File => New => New Project. Write application name as DynamicViewSwitcher. 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. | At this point, You will get a newly created android project successfully. |
Now, we will modify xml and kotlin file to use viewSwitcher dynamically.
2. Modify Values Folder
Open res/values/strings.xml file. Then, add below code into it.
<resources> <string name="app_name">DynamicViewSwitcher</string> <string name="next">Next</string> </resources>
3. Download Drawable Resources Needed
You may need images, stored in res/drawable folder, that will be used in the application. These drawable images will be used by viewSwitcher while creating different views in the application.
4. Modify Layout Folder
Open res/layout/activity_main.xml file. Then, 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"/> <LinearLayout android:id="@+id/rootContainer" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:orientation="vertical"> </LinearLayout> </LinearLayout>
In activity_main.xml file, we have defined a linearLayout, with id rootContainer, that will act as container for the viewSwitcher created programmatically in the application.
5. Create Android ViewSwitcher Programmatically / Dynamically in Kotlin
Open app/src/main/java/com.tutorialwing.dynamicviewswitcher/MainActivity.kt file. Then, add below code into it.
package com.tutorialwing.dynamicviewswitcher import android.os.Bundle import android.support.v7.app.AppCompatActivity import android.view.ViewGroup import android.view.animation.AnimationUtils import android.widget.Button import android.widget.ImageView import android.widget.LinearLayout import android.widget.ViewSwitcher class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val viewSwitcher = ViewSwitcher(this) val layoutParams = LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT) viewSwitcher.layoutParams = layoutParams 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 imageView1 = ImageView(this) val params1 = LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT) imageView1.layoutParams = params1 imageView1.setImageResource(R.drawable.pomegranate) val imageView2 = ImageView(this) val params2 = LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT) imageView2.layoutParams = params2 imageView2.setImageResource(R.drawable.zespri_kiwi) viewSwitcher.addView(imageView1) viewSwitcher.addView(imageView2) val linearLayout = findViewById<LinearLayout>(R.id.rootContainer) linearLayout?.addView(viewSwitcher) val btnNext = findViewById<Button>(R.id.btnNext) btnNext?.setOnClickListener { viewSwitcher.showNext() } } }
In MainActivity.kt file, we have done below things –
a. We have created viewSwitcher dynamically. Then, we have set layout params in it. Then, we have set in and out animations in it.
b. After that, we have created two imageViews that will be added a child views to viewSwitcher widget.
c. Then, we have added this viewSwitcher into linearLayout having id rootContainer.
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 src/main/AndroidManifest.xml file is –
<?xml version="1.0" encoding="utf-8"?> <manifest package="com.tutorialwing.dynamicviewswitcher" 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 Creating Android ViewSwitcher Programmatically in Kotlin.
