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();
       }
     
}
