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

【Android M】获取屏幕锁定的相关信息:“无”,“滑动”,“PIN码”,"图案","密码"
