audio – 无法在J2ME中重放声音

2019年8月3日 171次阅读

我在J2ME中重启声音有问题.我想在构造函数中创建播放器,然后调用playExplosion()来播放它,但它只播放一次.我正在使用Wireless Toolkit.

声音类

public class Sound () {

    private Player playerExplosion;

    public Sound() throws IOException, MediaException {
        // Explosion
        InputStream is = getClass().getResourceAsStream("/explosion.mid");
        playerExplosion = Manager.createPlayer(is, "audio/midi");
        playerExplosion.realize();
        playerExplosion.setLoopCount(1);
    }

    public void playExplosion() {
        try {
            System.out.println(playerExplosion.getState());
            playerExplosion.start();
        } catch (MediaException ex) {
            ex.printStackTrace();
        }
    }
}

MyMIDlet类

public class MyMIDlet extends MIDlet() {

    public Sound sound;

    public MyMIDlet() {
        // Init sound object
        try {
            sound = new Sound(this);
        } catch (Exception ex) {
            ex.printStackTrace();
        }

        // Test
        System.out.println("Start");

        for (int i = 0; i < 5; i++) {
            sound.playExplosion();

            // My sound is less than 1 second.
            try {
                Thread.sleep(2000);
            } catch (InterruptedException ex) {
                ex.printStackTrace();
            }
        }

        System.out.println("End");
    }
}

产量

Start
200
300
300
300
300
End

第一次,start()之前的playerExplosion状态为200(REALIZED).

对于第2次,第3次,第4次,第5次,start()之前的playerExplosion状态为300(PRE​​FETCH).

目前,我必须在playExplosion()方法中再次创建playerExplosion,但在真实设备中它太慢了.

最佳答案 删除后尝试

playerExplosion.setLoopCount(1);
