adb检测屏幕是否锁屏的判断方式

adb检测屏幕是否锁屏的判断方式

通过adb shell dumpsys window policy 查看屏幕状态

1、亮屏且有锁 showing=true和 screenState=SCREEN_STATE_ON

KeyguardServiceDelegate
      showing=true
      showingAndNotOccluded=true
      inputRestricted=false
      occluded=false
      secure=true
      dreaming=false
      systemIsReady=true
      deviceHasKeyguard=true
      enabled=true
      offReason=OFF_BECAUSE_OF_USER
      currentUser=-10000
      bootCompleted=true
      screenState=SCREEN_STATE_ON

2、灭屏且有锁 showing=true和 screenState=SCREEN_STATE_OFF

KeyguardServiceDelegate
     showing=true
     showingAndNotOccluded=true
     inputRestricted=false
     occluded=false
     secure=true
     dreaming=false
     systemIsReady=true
     deviceHasKeyguard=true
     enabled=true
     offReason=OFF_BECAUSE_OF_TIMEOUT
     currentUser=-10000
     bootCompleted=true
     screenState=SCREEN_STATE_OFF

3、亮屏且无锁 showing=false和screenState=SCREEN_STATE_ON

KeyguardServiceDelegate
      showing=false
      showingAndNotOccluded=true
      inputRestricted=false
      occluded=false
      secure=true
      dreaming=false
      systemIsReady=true
      deviceHasKeyguard=true
      enabled=true
      offReason=OFF_BECAUSE_OF_TIMEOUT
      currentUser=-10000
      bootCompleted=true
      screenState=SCREEN_STATE_ON

部分手机亮屏显示标识有区别 ，例如华为 screenState=2

KeyguardServiceDelegate
      showing=false
      showingAndNotOccluded=true
      inputRestricted=false
      occluded=false
      secure=true
      dreaming=false
      systemIsReady=true
      deviceHasKeyguard=true
      enabled=true
      offReason=2
      currentUser=-10000
      bootCompleted=true
      screenState=2

代码

def is_screen_lock(id):
    # ----------------------
    # 检测屏幕是否被锁，不同于屏幕点亮, 判断亮屏请使用 adbutils.is_screen_on
    # ----------------------
    try:
        command = 'adb -s ' + id + " shell dumpsys window policy"
        result = os.popen(command)
        lines = result.readlines()
        loc_flag = 0
        for i in range(len(lines)):
            if 'KeyguardServiceDelegate'.strip() in lines[i]:
                loc_flag = i + 1
        if 'showing=true' in lines[loc_flag] and loc_flag != 0:
            return True
        else:
            return False
    except Exception as e:
        print('获取手机lock状态异常',e)
        return False
