Question

如题所述

Answer 1

复制代码代码如下:

<uses-permission android：name="android.permission.WAKE_LOCK" />

<uses-permission android：name="android.permission.DISABLE_KEYGUARD" />

复制代码代码如下:

//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();

}

}
