屏幕亮度问题

private void setWakeLock(Context context){    PowerManager pm = (PowerManager) context    .getSystemService(Context.POWER_SERVICE);    SoundAlarmActivity.WakeLock = pm.newWakeLock(    PowerManager.FULL_WAKE_LOCK |        PowerManager.ACQUIRE_CAUSES_WAKEUP            | PowerManager.ON_AFTER_RELEASE, "BusSnoozeAlarm");    SoundAlarmActivity.WakeLock.acquire();}

?我原来是用

private void setWakeLock(Context context){    PowerManager pm = (PowerManager) context    .getSystemService(Context.POWER_SERVICE);    SoundAlarmActivity.WakeLock = pm.newWakeLock(    PowerManager.ACQUIRE_CAUSES_WAKEUP            | PowerManager.ON_AFTER_RELEASE, "Alarm");    SoundAlarmActivity.WakeLock.acquire();}

?

抛异常

?

这里呢要注意一下几个值的含义

Flag Value                  CPU Screen  KeyboardPARTIAL_WAKE_LOCK           On* Off OffSCREEN_DIM_WAKE_LOCK    On  Dim OffSCREEN_BRIGHT_WAKE_LOCK On  Bright  OffFULL_WAKE_LOCK          On  Bright  Bright

?貌似

ACQUIRE_CAUSES_WAKEUP和 PARTIAL_WAKE_LOCK?也不能同时用
