In my recyclerView contain few option with checkbox. I need those options be able to communicate to each other, how should I do it?
I guess the functions should written in onBindViewHolder() but I'm not sure how to do it. I search through internet but I couldn't find a similar way to solve my problem.
For example:
-------------------------
1. All (With Checkbox)
-------------------------
2. Banana (With Checkbox)
-------------------------
3. Apple (With Checkbox)
-------------------------
4. Meat (With Checkbox)
-------------------------
5. Coconut (With Checkbox)
-------------------------
So when I check on "All" option, the rest of the checkbox must be check automatically by using onCheckedChangeListener().
The major problem I faced is, I have no idea on how item affect another item within Recyclerview.
There are many ways to solve this
Ex. You can add isChecked property to your model
public class Fruit {
private Boolean isChecked;
}
Then set it to true/false in OnClickListener of each item. You check it value in OnBindViewHolder to show UI checkbox ticked / not ticked
For Select All option, you can set
isChecked = true
for all items in list.
So here is what you wanna be ?
In my opinion: First, we need add a property for Fruit to use CheckBox, ex: isFresh,... Second, change dataList (pass to RecyclerView Adapter) when tick CheckBox. Third, use adapter.notifyDataSetChanged()
to update RecyclerView UI.
