So how to achieve this task effectively?



Simple, I hope you all tried with list objects only. Surely this object will have the boolean variable to know whether this object is selected or not.

simple, In our recyclerview adapter's onBindViewHolder method, first set the checkedOnChangeListener of checkbox to null, and then set whether this object is selected or not to checkbox, and then add the checkedOnChangeListener to the checkbox. That's all. Issue solved.



onBindViewHolder will be look like
