I’m facing an issue in my app, and I need your help.
My app has 10 categories — for example: data1, data2, data3, etc.
When I click on any category, it opens the Show screen where all items (shayari/data) of that category are displayed in a ListView.
Each item has a Favorite (Heart) button below it.
When I click on that button, the button color changes from blue to red, and it gets saved in TinyDB — this part works fine.
But the problem is —
If I open data1 and favorite a few items, then go back and open data2,
the buttons at the same positions in data2 also appear red automatically even though I didn’t click them.
I don’t want this behavior.
Here’s what I actually want:
Each category should have its own separate Favorite data.
Only the items I favorite inside a particular category should appear red.
When I open another category, all buttons should remain default (blue) until I manually click them.
When I reopen the same category’s Show screen, the previously saved Favorites from TinyDB should appear red again.
I’m currently using these events:
Screen Initialize
On Bind View
Favorite Button Click
I want to know:
How to save category-wise Favorite data in TinyDB (how should I name the tags)?
Which variables should be used to keep Favorite states separate for each category?
And how to restore the Favorite state properly when reopening the Show screen?
If anyone can explain with example blocks or a short demo, it would be really helpful
This way, you can use it as a unique key (or generate one yourself) and store it in TinyDB when an item is added to the favorites.
Then, when you create the list, you can check whether that key is present in the favorites and color it red.
If the app doesn’t have much traffic, you could also just save the key (the formatted date) in a list (in tinyDB) and then check in OnBindView whether it’s present.
Currently the app is in development, so the data is not saved, my goal is that when I click on a category, and go inside, that is, to another screen, after clicking on the button in the list, that button should become red, then when I go inside that category again, the color of that button should appear red instead of black, and the button should be red in the same text, under the text on which I clicked the button, if I click on a new category, I don’t want the button in that position to be red, until I click on it
So, when you click the save button, store the item’s timestamp in a list in TinyDB, and when the list is generated in OnBindView, check if that timestamp is present (if in list set bgColor to red).
Sorry, I’m not sure how detailed I should be, do you need a more specific explanation?
To avoid drastically changing your data structure, I tried to keep as much of what you had done as possible.
Let me know if you need an explanation or if it’s already clear on its own.
even though I didn’t click them.
