Thank you John Naylor !
I searched it but use the wrong "key words".
I have changed the idea use this way.
Because people use this kind of possword,they always forget it or obfuscate it with other password. And it cann't be rememered in text in somewhere.
Thank you all the same !
First, i spend a lot of time in creating views, some views i need by my self, but some views not and to create a high quality view cost a lot of time. If you want to support me, then you can do it here by Paypal. :) This Class is optimized for B4A and B4I, but not for B4J. This is the First...
That's great !
I will explain how I do about it .
I used random number 1-9.
Every time you want to login and touch you screen ,the number's position is different.
Maybe you know what I mean,if you alway tap the same position,there is a trace.
