Android，如何在锁定屏幕上启动活动

问题描述：

我想通过锁定屏幕上的推送通知启动我的活动，而无需更改锁定.

I want launch my activity on push notification over lock screen without change in lock.

该活动是否有任何特殊许可?

Any special permission for that activity?

答

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1)
    {
        setShowWhenLocked(true);
        setTurnScreenOn(true);
        KeyguardManager keyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
        if(keyguardManager!=null)
            keyguardManager.requestDismissKeyguard(this, null);
    }
    else 
    {
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
                WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
                WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
    }
