import android.media.MediaPlayer;
import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;

import android.widget.MediaController;
import android.widget.Toast;

import java.io.IOException;

public class MainActivity extends AppCompatActivity
        implements SurfaceHolder.Callback, MediaPlayer.OnPreparedListener,
        MediaController.MediaPlayerControl {

    private SurfaceView surfaceView;
    private SurfaceHolder surfaceHolder;
    private MediaPlayer mediaPlayer;

    private MediaController mediaController;
    private Handler handler = new Handler();

    String videoSource =
            "https://sites.google.com/site/androidexample9/download/RunningClock.mp4";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        surfaceView = (SurfaceView)findViewById(R.id.surfaceview);
        surfaceHolder = surfaceView.getHolder();
        surfaceHolder.addCallback(this);

        surfaceView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(mediaController != null){
                    mediaController.show();
                }
                return false;
            }
        });

    }

    @Override

        } catch (IOException e) {
            e.printStackTrace();
            Toast.makeText(MainActivity.this,
                    "something wrong!\n" + e.toString(),
                    Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder,
                               int format, int width, int height) {

    }

    @Override

    }

    @Override
    public void onPrepared(MediaPlayer mp) {
        mediaPlayer.start();
        Toast.makeText(MainActivity.this,
                "onPrepared()", Toast.LENGTH_LONG).show();

        mediaController.setMediaPlayer(this);
        mediaController.setAnchorView(surfaceView);
        handler.post(new Runnable() {

            public void run() {
                mediaController.setEnabled(true);
                mediaController.show();
            }
        });
    }

    @Override
    public void start() {
        mediaPlayer.start();
    }

    @Override
    public void pause() {
        mediaPlayer.pause();
    }

    @Override
    public int getDuration() {
        return mediaPlayer.getDuration();
    }

    @Override
    public int getCurrentPosition() {
        return mediaPlayer.getCurrentPosition();
    }

    @Override
    public void seekTo(int pos) {
        mediaPlayer.seekTo(pos);
    }

    @Override
    public boolean isPlaying() {
        return mediaPlayer.isPlaying();
    }

    @Override
    public int getBufferPercentage() {
        return 0;
    }

    @Override
    public boolean canPause() {
        return true;
    }

    @Override
    public boolean canSeekBackward() {
        return true;
    }

    @Override
    public boolean canSeekForward() {
        return true;
    }

    @Override
    public int getAudioSessionId() {
        return mediaPlayer.getAudioSessionId();
    }
}
