1、这个方法是实现锁屏状态下唤醒手机,亮屏并解锁屏幕
加入权限:
2、这个收集的:
//锁屏、唤醒相关
private KeyguardManager km
private KeyguardLock kl
private PowerManager pm
private PowerManager.WakeLock wl
private void wakeAndUnlock(boolean b)
{
if(b)
{
//获取电源管理器对象
pm=(PowerManager) getSystemService(Context.POWER_SERVICE)
//获取PowerManager.WakeLock对象,后面的参数|表示同时传入两个值,最后的是调试用的Tag
wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "bright")
//点亮屏幕
wl.acquire()
//得到键盘锁管理器对象
km= (KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE)
kl = km.newKeyguardLock("unLock")
//解锁
kl.disableKeyguard()
}
else
{
//锁屏
kl.reenableKeyguard()
//释放wakeLock,关灯
wl.release()
}
}说明:
getSystemService取不到就获取上下文对象getActivity().getSystemService()。
