How to disable GridView scrolling in Android using Kotlin?

This example demonstrates how to disable GridView scrolling in Android using Kotlin.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:padding="8dp"
   tools:context=".MainActivity">
   <GridView
      android:id="@+id/gridLayout"
      android:layout_width="match_parent"
      android:layout_height="match_parent" />
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.kt

import android.content.Context
import android.os.Bundle
import android.view.MotionEvent
import android.view.View
import android.view.ViewGroup
import android.widget.*
import androidx.appcompat.app.AppCompatActivity
class MainActivity : AppCompatActivity() {
   private lateinit var gridView: GridView
      var imageIDs = arrayOf(
         R.drawable.ronaldo,
         R.drawable.andre,
         R.drawable.bernado,
         R.drawable.carvalho,
         R.drawable.bruno,
         R.drawable.patricio,
         R.drawable.pepe,
         R.drawable.felix,
         R.drawable.semedo,
         R.drawable.ronaldo
      )
      override fun onCreate(savedInstanceState: Bundle?) {
         super.onCreate(savedInstanceState)
         setContentView(R.layout.activity_main)
         title = "KotlinApp"
         gridView = findViewById(R.id.gridLayout)
         gridView.numColumns = 3
         gridView.adapter = ImageAdapterGridView(this)
         gridView.setOnTouchListener { _, event ->
         Toast.makeText(this@MainActivity, "Scrolling is Disabled", Toast.LENGTH_SHORT).show()
         event.action === MotionEvent.ACTION_MOVE
      }
   }
   inner class ImageAdapterGridView internal constructor(c: Context) : BaseAdapter() {
      private val context: Context = c
      override fun getCount(): Int {
         return imageIDs.size
      }
      override fun getItem(position: Int): Any? {
         return null
      }
      override fun getItemId(position: Int): Long {
         return 0
      }
      override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
         val imageView: ImageView
         if (convertView == null) {
            imageView = ImageView(context)
            imageView.layoutParams = AbsListView.LayoutParams(
               ViewGroup.LayoutParams.WRAP_CONTENT,
               ViewGroup.LayoutParams.WRAP_CONTENT
            )
            imageView.scaleType = ImageView.ScaleType.CENTER_CROP
            imageView.setPadding(30, 30, 30, 30)
         }
         else {
            imageView = convertView as ImageView
         }
         imageView.setImageResource(imageIDs[position])
         return imageView
      }
   }
}

Step 4 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.example.q11">
   <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>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click the Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen.
