Android唤醒、解锁屏幕

解锁、唤醒屏幕用到KeyguardManager，KeyguardLock，PowerManager，PowerManager.WakeLock
 
所需权限：

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();
 
        }
 
       
 
 }
