How can I create a TextView programmatically in a Linear Layout?

Question

I'm trying to make a TextView programmatically in a LinearLayout. The program includes a checking system to check if its been added already and the prompt for creating the textview is an option in a spinner. Here is the full onClick method for the spinner

public void onClick(String Ingredient, int i) {

            Toast.makeText(Kitchen.super.getContext(), "Selected "+Ingredient, Toast.LENGTH_SHORT).show();

            if(Ingredient.equals(tomatoSauce.name)) {

                if (tomatoSauce.init == 0){

                    tomatoSauce.init = 1;
                    TextView one = new TextView(getContext());
                    one.setText(Ingredient);
                    mainll.addView(one);

                }


            } else if(Ingredient.equals(chicken.name)) {

                chicken.init = 1;

            } else if(Ingredient.equals(olives.name)){

                olives.init  = 1;

            }

        }

The Linear layout is identified from the xml layout when the app is started in a separate method.

final LinearLayout mainll = (LinearLayout) getActivity().findViewById(R.id.main);

The app crashes upon selecting Tomato Sauce from the menu despite the lack of identified coding errors. Any help with this issue would be greatly appreciated.

Try to add below lines of code:

LinearLayout linearLayout =  (LinearLayout) findViewById(R.id.linear_layout_id);

TextView tv = new TextView(this);
tv.setText("hallo hallo");
tv.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));

linearLayout.addView(tv);
