How to create a gridView layout in an Android app?

This example demonstrates how do I gridView layout in an android app.
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"
   tools:context=".MainActivity">
   <GridView
      android:id="@+id/gridView"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:numColumns="2"/>
</RelativeLayout>
Step 3 – Open build.gradle(Module: app) and add the following dependency −
implementation 'com.android.support:gridlayout-v7:28.0.0'
Step 4 − Add the following code to src/MainActivity.java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.GridView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
   GridView gridView;
   String[] numberInWords = {"One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"};
   int[] numberImage = {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};
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      gridView = findViewById(R.id.gridView);
      MainAdapter mainAdapter = new MainAdapter(MainActivity.this, numberInWords,numberImage);
      gridView.setAdapter(mainAdapter);
      gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
         @Override
         public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(getApplicationContext(), "You CLicked " + numberInWords[+position],
            Toast.LENGTH_SHORT).show();
         }
      });
   }
}
Step 5 – Add the following code to MainAdapter.java
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;
class MainAdapter extends BaseAdapter {
   private Context context;
   private LayoutInflater layoutInflater;
   private String[] numbersInWords;
   private int[] numberImage;
   private ImageView imageView;
   private TextView textView;
   public MainAdapter(Context c, String[] numbersInWords,int[] numberImage){
      context = c;
      this.numberImage = numberImage;
      this.numbersInWords = numbersInWords;
   }
   @Override
   public int getCount() {
      return numbersInWords.length;
   }
   @Override
   public Object getItem(int position) {
      return null;
   }
   @Override
   public long getItemId(int position) {
      return 0;
   }
   @Override
   public View getView(int position, View convertView, ViewGroup parent) {
      if (layoutInflater==null) {
         layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
      }
      if (convertView==null){
         convertView = layoutInflater.inflate(R.layout.rowitem, null);
      }
      imageView = convertView.findViewById(R.id.imageView);
      textView = convertView.findViewById(R.id.textView);
      imageView.setImageResource(numberImage[position]);
      textView.setText(numbersInWords[position]);
      return convertView;
   }
}
Step 6 – Create a new layout resource file(rowItem) and add the following code in rowitem.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:orientation="vertical"
   android:padding="24sp"
   android:gravity="center">
   <ImageView
      android:layout_width="100dp"
      android:layout_height="100dp"
      android:id="@+id/imageView" />
   <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/textView"
      android:text="Numbers"
      android:textSize="24sp"
      android:layout_marginTop="8dp" />
</LinearLayout>
Step 7 - 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 android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –
