Android应用程序和模式锁定屏幕

Question

I am currently developing an app for android 2.2 or above.

I want to allow the user to enable a login before having access to the app. I want to allow the user to choose between various types of login like password, pin or pattern.

I was wondering if would be possible to add a pattern lock to my own app. Is there a plugin I can use to create one or use android's pattern lock for my own app. I only want this for the app I don't want it to change how the actual device is locked.

Thanks for any help you can provide.

Answer 1

I dont think there is a widget for this. I would create a matrix of images 3x3 give them each a listener and keep track of the order the user presses them. Then take the order, 2,3,6,5,8 for example, save them as a string "23658" this is the password! hash and save that somewhere. whenever a user inputs the button order compare the input hash to the saved one.

如果有任何正在寻找答案，我发现这个库非常有用，并且比在GitHub上托管的android-lockpattern好多了
