唤醒屏幕并解锁

代码示例

public static void wakeUpAndUnlock(Context context){ 
    KeyguardManager km= (KeyguardManager)context.getSystemService(Context.KEYGUARD_SERVICE);
    KeyguardManager.KeyguardLock kl = km.newKeyguardLock( "unLock" );

    //解锁 
    kl.disableKeyguard(); 

    //获取电源管理器对象 
    PowerManager pm=(PowerManager) context.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LogCat里用的Tag 
    PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.ACQUIRE\_CAUSES\_WAKEUP | PowerManager.SCREEN\_DIM\_WAKE_LOCK, "bright" ); 

    //点亮屏幕 
    wl.acquire(); 

    //释放 
    wl.release(); 
}

需要添加权限

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