Android AudioManager.FLAG_VIBRATE 不工作

Question

我在 Activity 中执行以下代码来设置铃声模式和值:

void setRinger(int value) {
    AudioManager manager = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
    manager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
    manager.setStreamVolume(AudioManager.STREAM_RING, value, AudioManager.FLAG_PLAY_SOUND);
}

void setSilent() {
    AudioManager manager = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
    manager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
    manager.setStreamVolume(AudioManager.STREAM_RING, 0, AudioManager.FLAG_SHOW_UI);
}

void setVibrate() {
    AudioManager manager = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
    manager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
    manager.setStreamVolume(AudioManager.STREAM_RING, 0, AudioManager.FLAG_VIBRATE);
}

setRinger() 设置铃声值并播放声音作为确认。setSilent() 设置静音模式并显示“toast”作为确认。setVibrate() 设置振动模式，但手机不振 Action 为确认。

我使用的是 HTC Wildfire S (Android 2.3.5)。当我使用电话上的按钮更改铃声音量时，振动正常。

我做错了什么？任何空间特权？我尝试将 android.permission.VIBRATE 添加到 list 中 - 没有帮助。

经许可的 list :

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".DroidUtilityActivity"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>
<uses-permission android:name="android.permission.VIBRATE" />
</manifest>

Logcat 输出(我切断了大部分日志)只是为了证明调用了代码:

我遇到了和你一样的问题(使用 HTC Desire HD)。在我的例子中，同时使用两个标志(AudioManager.FLAG_VIBRATE 和 AudioManager.FLAG_SHOW_UI)解决了问题——手机振动并出现振动对话框。但是，当我仅使用 AudioManager.FLAG_VIBRATE 标志时，手机不会振动。在我的代码下面:

AudioManager manager = (AudioManager)this.getSystemService(Context.AUDIO_SERVICE);
manager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
int currentStreamRing = manager.getStreamVolume(AudioManager.STREAM_RING);
manager.setStreamVolume(AudioManager.STREAM_RING,currentStreamRing,AudioManager.FLAG_VIBRATE+AudioManager.FLAG_SHOW_UI);
