reenableKeyguard reenableKeyguard

void reenableKeyguard() Reenable the keyguard. reenableKeyguard（）void重新启用键盘保护。 The keyguard will reappear if the previous call to disableKeyguard() caused it to be hidden. 如果先前对disableKeyguard（）的调用导致隐藏，则键盘保护将重新出现。 A good place to call this is from onPause() Note: This call has no effect while any DevicePolicyManager is enabled that requires a password. 从onPause（）调用它是一个好地方。注意：当启用任何需要密码的DevicePolicyManager时，此调用无效。

This method requires the caller to hold the permission DISABLE_KEYGUARD. 此方法要求调用方持有权限DISABLE_KEYGUARD。

Your app has to be the one to call disableKeyguard() first, else you cannot lock it using reenableKeyguard() 您的应用是一个叫disableKeyguard()第一，否则你无法使用锁定reenableKeyguard()
