Gridview in Android Studio with source code

How to use grid view in Android Studio.

We will set the data in the gridview using the adapter class.

Gridview is used when we want to show the name and picture grid layout.

Set the automatic item scrollable view in the gridview.

First of start android studio.

Type the name of your Project.

MainActivity.java

package com.pd.gridview;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.widget.GridView;

public class MainActivity extends AppCompatActivity {
GridView gridView;

int Images[]={R.drawable.ic_baseline_add_a_photo_24,
        R.drawable.ic_baseline_chat_24,
        R.drawable.ic_baseline_notifications_active_24,
        R.drawable.ic_baseline_perm_media_24,
        R.drawable.ic_baseline_settings_applications_24,
        R.drawable.ic_baseline_store_mall_directory_24,
        R.drawable.ic_baseline_store_mall_directory_24,
        R.drawable.ic_baseline_store_mall_directory_24};
String name[]={"one","two","three","four","five","six","seven","eight"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gridView=findViewById(R.id.gridview);

MyAdapter myAdapter=new MyAdapter(MainActivity.this,Images,name);
        gridView.setAdapter( myAdapter);
    }
}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <GridView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:numColumns="2"
        android:columnWidth="100dp"
        android:id="@+id/gridview"/>

</LinearLayout>

Now Create an Adapter Class named

MyAdapter.java

package com.pd.gridview;

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;

public class MyAdapter extends BaseAdapter {
private Context context;
private final  int images[];
private final String name[];

private ImageView imageView;
private TextView textView;

private LayoutInflater layoutInflater;

    public MyAdapter(Context context, int[] images, String[] name) {
        this.context = context;
        this.images = images;
        this.name = name;
    }

    @Override
    public int getCount() {
        return name.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) {
layoutInflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView=layoutInflater.inflate(R.layout.singledata,null);
imageView=(ImageView)convertView.findViewById(R.id.imageview);
textView=(TextView)convertView.findViewById(R.id.textview);

imageView.setImageResource(images[position]);
textView.setText(name[position]);
return convertView;
    }
}

Now View data in textview,we will create xml file to display data.

singledata.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/teal_700"
    android:gravity="center"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/imageview"
        android:layout_width="100sp"
        android:layout_height="100sp"
        android:src="@drawable/ic_launcher_background" />

    <TextView
        android:id="@+id/textview"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/app_name"
        android:textSize="25dp" />
</LinearLayout>
