public class AutoActivity extends AppCompatActivity {

ImageView playBtn;

private int[] soundIndex = {
        R.raw.r0, R.raw.r1, R.raw.r2, R.raw.r3, R.raw.r4, R.raw.r5, R.raw.r6, R.raw.r7, R.raw.r8, R.raw.r9,

        R.raw.r60, R.raw.r61, R.raw.r62, R.raw.r63, R.raw.r64, R.raw.r65, R.raw.r66, R.raw.r67, R.raw.r68, R.raw.r69,
        R.raw.r70, R.raw.r71, R.raw.r72, R.raw.r73, R.raw.r74, R.raw.r75, R.raw.r76, R.raw.r77, R.raw.r78, R.raw.r79,
        R.raw.r80, R.raw.r81, R.raw.r82, R.raw.r83};
int mCompleted = 0;


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

    final MediaPlayer mediaPlayer = MediaPlayer.create(this, soundIndex[0]);


    //Play button initialize
    playBtn = findViewById(R.id.playBtn);

    playBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mediaPlayer.isPlaying()){
                mediaPlayer.pause();
                playBtn.setImageResource(R.drawable.play);
            }else {
                mediaPlayer.start();
                playBtn.setImageResource(R.drawable.pause);
            }
        }
    });
    mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
        @Override
        public void onCompletion(MediaPlayer mp) {
            mCompleted++;
            mp.reset();
            if (mCompleted < soundIndex.length) {
                try {
                    AssetFileDescriptor afd = getResources().openRawResourceFd(soundIndex[mCompleted]);
                    if (afd != null) {
                        mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
                        afd.close();
                        mp.prepare();
                        mp.start();
                    }
                } catch (Exception ex) {
                    ex.printStackTrace();
                }

            } else if (mCompleted >= soundIndex.length) {
                mCompleted = 0;
                try {
                    AssetFileDescriptor afd = getResources().openRawResourceFd(soundIndex[mCompleted]);
                    if (afd != null) {
                        mp.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getLength());
                        afd.close();
                        mp.prepare();
                        mp.start();
                    }
                } catch (Exception ex) {
                    ex.printStackTrace();
                }
            } else {
                mCompleted = 0;
                mp.release();
                mp = null;
            }

        }
    });
}

This is complete code which you can play songs continuously in loop
