        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />
    </RelativeLayout>

I am trying to create dynamic fields each time the user clicks on the add new field button. Will insert a new field below.

I’m trying to do it this way, but it’s not working

    private void createNewTextView() {

            RelativeLayout rl = (RelativeLayout) findViewById(R.id.relativeLayoutPacient);

            // add edittext
            EditText et = new EditText(this);
            RelativeLayout.LayoutParams param = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

            et.setId(numberOfLinesCardapio+1);
            et.setHint("Alimento");
            et.setTextSize(16);
            et.setId(numberOfLinesCardapio + 1);
            et.setTextColor(Color.parseColor("#ffffffff"));
            et.setInputType(InputType.TYPE_TEXT_VARIATION_PERSON_NAME);

            int id = et.getId();

            param.addRule(RelativeLayout.BELOW, R.id.editTextCardapioHora);

            rl.addView(et, param);

            RelativeLayout.LayoutParams editParam = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
            editParam.addRule(RelativeLayout.BELOW, et.getId());
            editTextRestricaoAlimentar.setLayoutParams(editParam);

            numberOfLinesCardapio++;
        }

Someone gives me a light to solve this problem?

You’re not getting in the right position.
