managing a click on the element of an android tablelayout-CodePudding

I need to manage a specific time slot as shown in the picture.

I need that when I click on a specific TextView, it opens a new fragment sending me which element was clicked on. That is the layout file

</TableLayout>

I tried this way, but I always get the row id and not the child id.

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    binding = FragmentWeekBinding.inflate(inflater, container, false);
    View root = binding.getRoot();
    binding.row16.setClickable(true);
    binding.row16.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            int id = view.getId();
            Toast.makeText(getContext(), "pos:"   id, Toast.LENGTH_SHORT).show();
        }
    });
    return root;

}

I also tried tag but it still doesn't work, does anyone have any solution to recommend? I would be very grateful

CodePudding user response：

Set an onClickListener on every TextView.

Example: https://www.folkstalk.com/tech/onclicklistener-and-table-layout-with-example/

It's done on a Button. Change to a TextView.

CodePudding user response：

// The row the view is in
TableRow row = (TableRow) view.getParent();
// It's index
int index = tableLayout.indexOfChild(row);
