如何让MediaPlayer重复播放声音？

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

public class MainActivity extends AppCompatActivity {
    private MediaPlayer mediaPlayer;

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

        // 创建MediaPlayer对象
        mediaPlayer = MediaPlayer.create(this, R.raw.audio);

        // 设置循环播放
        mediaPlayer.setLooping(true);

        // 开始播放
        mediaPlayer.start();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();

        // 释放MediaPlayer资源
        if (mediaPlayer != null) {
            mediaPlayer.release();
            mediaPlayer = null;
        }
    }
}
