如何连续播放raw文件夹中的歌曲，不会循环

import android.media.MediaPlayer;
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {
    private MediaPlayer mediaPlayer;
    private int[] songResources = {R.raw.song1, R.raw.song2, R.raw.song3}; // 替换为你的歌曲资源ID
    private int currentSongIndex = 0;

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

        playNextSong();
    }

    private void playNextSong() {
        if (mediaPlayer != null) {
            mediaPlayer.release();
        }

        mediaPlayer = MediaPlayer.create(this, songResources[currentSongIndex]);
        mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                currentSongIndex++;
                if (currentSongIndex < songResources.length) {
                    playNextSong();
                } else {
                    // 所有歌曲播放完毕后的处理
                    mediaPlayer.release();
                    mediaPlayer = null;
                }
            }
        });

        mediaPlayer.start();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        if (mediaPlayer != null) {
            mediaPlayer.release();
            mediaPlayer = null;
        }
    }
}
