KiOS | Learning operating-systems by creating a kernel in Rust

I have one page called products. When page is loaded it shows productsfragment. This fragment has one RecyclerView which doesn't have any problem. On selecting a product a new fragment opens up and shows the list of product prices fragment. This fragment has one RecyclerView and the scrolling here doesn't works.

I tried gridview and cardview but they too are not scrolling. I tried gridview in scroll view or nested scroll view, they are also not scrolling.

here is my fragment with RecyclerView which is not scrolling

I have an App which have behavior like a KIOS. There is an Activity will show to user and user cannot back or close it because it's need a password.

There is one case if the owner of App forgot the password. So I need to implement external setting (like IOS) outside the App to change value on my Shared Preferences to close the Activity KIOS.

I read some articles and the close way is using Accessibility but the information and example about this is so difficult to find. So I still learn and testing about it.

Here what I've done:

SettingProgram.java

Trying to convert an entity object to local object so i can use it for further transformations.

I want to ask Bro, how to make a product review by the user who has bought the goods, I've tried to make, but not successful, the result is like this:

first, if the user (buyer) buy the goods and do the review is successful, but the form for the review is still there ... how do I remove the form for the user (buyer) who has done a review for the goods?

can do a review, when the product has not been reviewed #View Image

the form still exists despite having reviewed the goods #View Image

secondly, it is already purchased and reviewed by other users, the user (buyer with different account) make a purchase and succeed, but if make a review of the same item, can not the form does not appear, but already made a purchase ..

there is no form for the user, even after making a purchase #View Image

essentially like this if the goods have not been reviewed, can do the review and the form is still there even though it has done a review. but if you already have a review, other users (buyers) can not review the item (the form does not appear). well that's the problem where is Bro ?, in conditioning _ (if) _? or anything else?
