Galaxy S 上的扬声器关闭问题

发布于 2024-10-04 19:14:46 字数 362 浏览 0 评论 0原文

有其他人在 Samsung Galaxy S 上遇到过这种情况吗？

当我使用以下方法打开扬声器时，它工作正常：

audioManager.setSpeakerphoneOn(true);

但是当我尝试相反的方法将其关闭时：

audioManager.setSpeakerphoneOn(false);

扬声器保持打开状态，并通过扬声器而不是设备上的耳机播放音频。

以上适用于 Nexus One 和 HTC Hero，前几天刚买了一台三星 Galaxy，但不起作用，还有其他人遇到过这个问题吗？也许知道为什么会发生这种情况以及是否有解决方法？

Has anyone else experienced this on the Samsung Galaxy S?

When I use the folowing to turn the Loudspeaker on it works fine:

audioManager.setSpeakerphoneOn(true);

But when I try the opposite to turn it off:

audioManager.setSpeakerphoneOn(false);

The Loudspeaker stays on and audio is played via that instead of the ear piece on the device.

The above works on the Nexus One and HTC Hero, just got a Samsung Galaxy the other day and it doesn't work, has anyone else encountered the issue and perhaps know why it is happening and if there is a work around?

这是我必须做的才能让它工作：

if (isGalaxyS()) {
    audioManager.setMode(AudioManager.MODE_IN_CALL);
    audioManager.setMode(AudioManager.MODE_NORMAL);
    audioManager.setSpeakerphoneOn(flag);
}

似乎这种来回以某种方式重置了音频通道。为了完整起见，这里是 isGalaxyS() （请注意，我只在 Epic 上测试过它！）：

public static boolean isGalaxyS() {
    String model = Build.MODEL;
    return  model.equalsIgnoreCase("GT-I9000") ||       // base model
            model.equalsIgnoreCase("SPH-D700") ||       // Epic         (Sprint)
            model.equalsIgnoreCase("SGH-I897") ||       // Captivate    (AT&T)
            model.equalsIgnoreCase("SGH-T959") ||       // Vibrant      (T-Mobile)
            model.equalsIgnoreCase("SCH-I500") ||       // Fascinate    (Verizon)
            model.equalsIgnoreCase("SCH-I400");         // Continuum    (T-Mobile) 
}

Here's what I have to do to get it to work:

if (isGalaxyS()) {
    audioManager.setMode(AudioManager.MODE_IN_CALL);
    audioManager.setMode(AudioManager.MODE_NORMAL);
    audioManager.setSpeakerphoneOn(flag);
}

Seems that this back and forth somehow resets the audio channel. For completeness here's isGalaxyS() (note that I've only tested this on the Epic!):

public static boolean isGalaxyS() {
    String model = Build.MODEL;
    return  model.equalsIgnoreCase("GT-I9000") ||       // base model
            model.equalsIgnoreCase("SPH-D700") ||       // Epic         (Sprint)
            model.equalsIgnoreCase("SGH-I897") ||       // Captivate    (AT&T)
            model.equalsIgnoreCase("SGH-T959") ||       // Vibrant      (T-Mobile)
            model.equalsIgnoreCase("SCH-I500") ||       // Fascinate    (Verizon)
            model.equalsIgnoreCase("SCH-I400");         // Continuum    (T-Mobile) 
}
