HorizontalScrollView in Kotlin
In Android ScrollView allows multiple views that are places within the parent view group to be scrolled. Scrolling in the android application can be done in two ways either Vertically or Horizontally.
In this article, we will be discussing how to create a Horizontal ScrollView in Kotlin .
XML Attributes | Description |
---|---|
android:fillViewport | It defines whether the horizontal scrollview should stretch its content to fill the viewport. |
android:layout_height | Sets the height of the horizontal scroll view |
android:layout_width | Sets the width of the horizontal scroll view |
android:src | Sets background of the image |
android:id | Sets unique id of the view |
Let’s start by first creating a project in Android Studio. To do so, follow these instructions:
First step is to create a new Project in Android Studio. For this follow these steps:
- Click on File, then New and then New Project and give name whatever you like
- Then, select Kotlin language Support and click next button.
- Select minimum SDK, whatever you need
- Select Empty activity and then click finish.
Modify activity_main.xml file
<? xml version = "1.0" encoding = "utf-8" ?> < HorizontalScrollView xmlns:android = "http://schemas.android.com/apk/res/android" android:layout_width = "match_parent" android:layout_height = "match_parent" > < LinearLayout android:layout_width = "200dp" android:layout_height = "200dp" android:layout_marginTop = "20dp" android:orientation = "horizontal" > < ImageView android:id = "@+id/image1" android:layout_width = "200dp" android:layout_height = "200dp" android:layout_marginRight = "20dp" android:src = "@mipmap/image1" /> < ImageView android:id = "@+id/image2" android:layout_width = "200dp" android:layout_height = "200dp" android:layout_marginRight = "20dp" android:src = "@mipmap/image2" /> < ImageView android:id = "@+id/image3" android:layout_width = "200dp" android:layout_height = "200dp" android:layout_marginRight = "20dp" android:src = "@mipmap/image3" /> < ImageView android:id = "@+id/image4" android:layout_width = "200dp" android:layout_height = "200dp" android:layout_marginRight = "20dp" android:src = "@mipmap/image4" /> </ LinearLayout > </ HorizontalScrollView > |
Add Images
We need to add some images which can be used for scrolling purpose. So, we have to copy the images from our local computer path to app/res/mipmap folder.
Note: We have added the images to mipmap folder instead of drawable folder because the size of the images is very large.
Create HorizontalScrollView in MainActivity.kt file
Open app/src/main/java/yourPackageName/MainActivity.kt and do the following changes:
package com.w3wiki.myfirstKotlinapp import androidx.appcompat.app.AppCompatActivity import android.os.Bundle class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super .onCreate(savedInstanceState) setContentView(R.layout.activity_main) } } |
AndroidManifest.xml file
<? xml version = "1.0" encoding = "utf-8" ?> < manifest xmlns:android = "http://schemas.android.com/apk/res/android" package = "i.apps.hscrollview" > < 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 > |
