How to disable GridView scrolling in Android?

This example demonstrates how do I disable gridView scrolling in android.

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.java

import androidx.appcompat.app.AppCompatActivity;
import android.annotation.SuppressLint;
import android.content.Context;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   GridView gridView;
   Integer[] imageIDs = {R.drawable.one, R.drawable.two, R.drawable.three, R.drawable.four, R.drawable.five, R.drawable.six, R.drawable.seven, R.drawable.eight, R.drawable.nine, R.drawable.ten};
   @SuppressLint("ClickableViewAccessibility")
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      gridView = findViewById(R.id.gridLayout);
      gridView.setAdapter(new ImageAdapterGridView(this));
      gridView.setOnTouchListener(new View.OnTouchListener() {
         @Override
         public boolean onTouch(View v, MotionEvent event) {
            Toast.makeText(MainActivity.this, "Scrolling is Disabled", Toast.LENGTH_SHORT).show();
            return event.getAction() == MotionEvent.ACTION_MOVE;
         }
      });
   }
   public class ImageAdapterGridView extends BaseAdapter {
      private Context context;
      ImageAdapterGridView(Context c) {
         context = c;
      }
      public int getCount() {
         return imageIDs.length;
      }
      public Object getItem(int position) {
         return null;
      }
      public long getItemId(int position) {
         return 0;
      }
      public View getView(int position, View convertView, ViewGroup parent) {
         ImageView imageView;
         if (convertView == null) {
            imageView = new ImageView(context);
            imageView.setLayoutParams(new
            GridView.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.MATCH_PARENT));
            imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
            imageView.setPadding(20, 20, 20, 20);
         } else {
            imageView = (ImageView) convertView;
         }
         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="app.com.sample">
   <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 the 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 −
