I want to open the second tab from the first tab when I click an item in the list

Question

I have 3 tabs. The first tab contains the 1st operation. The second tab contains the 2nd operation.

The 1st action contains a list of items.

When I click on an item in the list, I pass on its information through the intention to the 2nd operation on the 2nd tab.

Now I wanted to launch a second tab displaying the 2nd activity containing information from the 1st action.

how to achieve this?
