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 nestedScrollView programmatically in kotlin in the application. We will also learn how to add nestedScrollView to linearLayout programmatically in android application.

Tutorialwing Kotlin Dynamic NestedScrollView Output
Getting Started
At first, we will create android project. Then, we will create and use nestedScrollView 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 DynamicNestedScrollView. 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 other files to use nestedScrollView programmatically in kotlin file.
2. Modify Values Folder
Open res/values/strings.xml file. Then, add below code into it.
<resources> <string name="app_name">DynamicNestedScrollView</string> <string name="no_image">No Image</string> <string name="nested_scroll_text">Tutorialwing.com presents tutorial on NestedScrollView! NestedScrollView is just like ScrollView, but it supports acting as both a nested scrolling parent and child on both new and old versions of Android. Nested scrolling is enabled by default. NestedScrollView is used when there is need for scrolling inside another scrolling view. Normally this would be difficult task because system would be unable to decide which view to scroll. This is where NestedScrollView comes into role. </string> </resources>
3. Download Drawable Resources Needed
You will need some images, stored in res/drawable folder, to be used in the application. These drawable images will be used by views inside scrollView.
4. Modify Layout Folder
Open res/layout/activity_main.xml file. Then, add below code into it.
<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginBottom="20dp" android:gravity="center" android:orientation="vertical"> <LinearLayout android:id="@+id/rootContainer" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> </LinearLayout> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="20dp" android:contentDescription="@string/no_image" android:src="@drawable/guava"/> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="20dp" android:contentDescription="@string/no_image" android:src="@drawable/jackfruit"/> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="20dp" android:contentDescription="@string/no_image" android:src="@drawable/mix_fruit"/> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="20dp" android:contentDescription="@string/no_image" android:src="@drawable/pomegranate"/> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="20dp" android:contentDescription="@string/no_image" android:src="@drawable/strawberry"/> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="20dp" android:contentDescription="@string/no_image" android:src="@drawable/zespri_kiwi"/> </LinearLayout> </ScrollView>
In activity_main.xml file, we have completed below things –
a. We have defined scrollView and a linearLayout with id rootContainer that will act as container for the nestedScrollView created programmatically in the application.
b. All the imageViews have been defined inside linearLayout, a direct child of scrollView.
5. Create Android NestedScrollView Programmatically / Dynamically in Kotlin
Open app/src/main/java/com.tutorialwing.dynamicnestedscrollview/MainActivity.kt file. Then, add below code into it.
package com.tutorialwing.dynamicnestedscrollview import android.graphics.Color import android.os.Bundle import android.support.v4.widget.NestedScrollView import android.support.v7.app.AppCompatActivity import android.view.ViewGroup import android.widget.LinearLayout import android.widget.TextView class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) // Create NestedScrollView Dynamically val nestedScrollView = NestedScrollView(this) val layoutParams = LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, 200) layoutParams.setMargins(30, 30, 30, 30) nestedScrollView.layoutParams = layoutParams nestedScrollView.setBackgroundColor(Color.WHITE) // Add NestedScrollView to linearLayout having id rootContainer val layout = findViewById<LinearLayout>(R.id.rootContainer) layout?.addView(nestedScrollView) // Created LinearLayout and add it to NestedScrollView val linearLayout = LinearLayout(this) val linearParams = LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT) linearLayout.orientation = LinearLayout.VERTICAL linearLayout.layoutParams = linearParams nestedScrollView.addView(linearLayout) // Created TextView and add it to linearLayout val textView = TextView(this) val textParams = LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT) textView.layoutParams = textParams textView.text = getString(R.string.nested_scroll_text) textView.setPadding(15, 15, 15, 15) linearLayout.addView(textView) } }
We have defined nestedScrollView programmatically in kotlin file (i.e. in MainActivity.kt file). Then, we have set layout params, margins etc. in it. Then, we have added it in linearLayout having id rootContainer. After that, we have created linearLayout as a direct child of nestedScrollView. Then, we have created textView and added in linearLayout.
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.dynamicnestedscrollview" 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 NestedScrollView Programmatically in Kotlin.
