【Android M获取屏幕锁定的相关信息（“无”，“滑动”，“PIN码”，" 图案" ，" 密码" ）】一　如何判断当前锁定方式是否为"无"？
通过LockPatternUtils类的isLockScreenDisabled判断

二　如何判断当前锁定方式是否为"滑动"？
通过LockPatternUtils类的! isSecure方法和! isLockScreenDisabled方法判断

三　如何判断当前锁定方式是否为"安全密码"锁屏？
通过LockPatternUtils类的isSecure方法和getKeyguardStoredPasswordQuality方法判断

PS:LockPatternUtils类为平台内部类，第三方应用层无法获取该类，可考虑通过反射调用亦可考虑其他方式判断
