How to get id of the item clicked from layout action in android?

Question

I am validating the EditText value by clicking anywhere inside the window. But for some buttons, I want to do something different from the validation functionality. How can I get the id of the item from the layout action. Here my layout is ConstraintLayout. Tried the below code but it's not working.

window_layout.setOnClickListener(new 

    View.OnClickListener() {
                @Override
                public void onClick(View v) {
                   
    
                    switch (v.getId()) {
                        case R.id.btn_tech:
                            setButtonsVisibility();
                             break;
                    }
    
                       
                }
            });

Please suggest a better way to implement that.

What you're doing right now is adding the listener to the parent view. You need to set the listener to the individual views.

You can add a listener variable and add it to the different button views.

You can also iterate your constraint layout child views and setting the listener individually.

    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            switch (v.getId()) {
                case R.id.btn_tech:
                    setButtonsVisibility();
                    break;
            }
        }
    }

    for(int i = 0; i <= windowLay.getChildCount(); i++) {
        rec.getChildAt(i).setOnClickListener(listener);
    }
