How to Add VideoView in android

In activity_main.xml add these lines of codes:-

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    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:orientation="vertical"    android:layout_height="match_parent"    tools:context=".MainActivity">

    <VideoView        android:layout_alignParentTop="true"        android:layout_alignParentBottom="true"        android:layout_alignParentLeft="true"        android:layout_alignParentRight="true"        android:id="@+id/simpleVideoView"        android:layout_width="fill_parent"        android:layout_height="fill_parent" />

</RelativeLayout>

In MainActivity.java class file add these lines of codes:-

package com.example.videointro;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.util.DisplayMetrics;
import android.widget.Toast;
import android.widget.VideoView;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        // initiate a video view        VideoView simpleVideoView = (VideoView) findViewById(R.id.simpleVideoView);
        simpleVideoView.setVideoURI(Uri.parse("android.resource://" + getPackageName() + "/" + R.raw.samplevideo));
        // start a video        simpleVideoView.start();

        // implement on completion listener on video view        simpleVideoView.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                Intent i = new Intent(MainActivity.this,Secondscreen.class );
                startActivity(i);
                //Toast.makeText(getApplicationContext(), "Thank You...!!!", Toast.LENGTH_LONG).show(); // display a toast when an video is completed            }
        });
        simpleVideoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {
            @Override
            public boolean onError(MediaPlayer mp, int what, int extra) {
                Toast.makeText(getApplicationContext(), "Oops An Error Occur While Playing Video...!!!", Toast.LENGTH_LONG).show(); // display a toast when an error is occured while playing an video                return false;
            }
        });
    }
}

In res folder add new directory name it with raw and add your video within it.
