    for that you have to implement to activity

    OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener,
    OnVideoSizeChangedListener, SurfaceHolder.Callback, MediaPlayerControl
    

    check below working code

    package com.example.demo;
    import android.app.Activity;
    import android.media.AudioManager;
    import android.media.MediaPlayer;
    import android.media.MediaPlayer.OnBufferingUpdateListener;
    import android.media.MediaPlayer.OnCompletionListener;
    import android.media.MediaPlayer.OnPreparedListener;
    import android.media.MediaPlayer.OnVideoSizeChangedListener;
    import android.net.Uri;
    import android.os.Bundle;
    import android.os.Handler;
    import android.view.MotionEvent;
    import android.view.SurfaceHolder;
    import android.view.SurfaceView;
    import android.view.View;
    import android.widget.MediaController;
    import android.widget.MediaController.MediaPlayerControl;
    import android.widget.ProgressBar;
    
    public class MainActivity extends Activity implements  OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener,
    OnVideoSizeChangedListener, SurfaceHolder.Callback, MediaPlayerControl{
        String url = "your video url";
        MediaPlayer mMediaPlayer ;
        SurfaceView mSurfaceView ;
        SurfaceHolder holder ;
        private ConstantAnchorMediaController controller = null;
        ProgressBar progressBar1 ;
        MediaController mcontroller ;
        Handler handler ;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            progressBar1 = (ProgressBar)findViewById(R.id.progressBar1);
            SurfaceView v = (SurfaceView) findViewById(R.id.surface); 
            handler = new Handler();
            holder = v.getHolder(); 
            holder.addCallback(this);
            playVideo();
    
        }
        private void playVideo() {
            try {
                mcontroller = new MediaController(this);
                mMediaPlayer = MediaPlayer.create(this, Uri.parse(url));
                mMediaPlayer.setOnBufferingUpdateListener(this);
                mMediaPlayer.setOnCompletionListener(this);
                mMediaPlayer.setOnPreparedListener(this);
                mMediaPlayer.setScreenOnWhilePlaying(true);
                mMediaPlayer.setOnVideoSizeChangedListener(this);
                mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        @Override
        public boolean onTouchEvent(MotionEvent event) {
             mcontroller.show();
             return false;
        }
        @Override

            } catch (IllegalStateException e) {
                e.printStackTrace();
            }
