如何在几秒钟后播放MediaPlayer声音？

import android.media.MediaPlayer;
import android.os.Handler;

public class MainActivity extends AppCompatActivity {
    private MediaPlayer mediaPlayer;

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

        mediaPlayer = new MediaPlayer();
        try {
            mediaPlayer.setDataSource("path_to_audio_file");
            mediaPlayer.prepare();
        } catch (IOException e) {
            e.printStackTrace();
        }

        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                mediaPlayer.start();
            }
        }, 5000); // 设置延迟时间为5秒
    }

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