Można utworzyć ją tak:

EditText myEditText = new EditText(context); // Pass it an Activity or Context 
myEditText.setLayoutParams(new LayoutParams(..., ...)); // Pass two args; must be LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT, or an integer pixel value. 
myLayout.addView(myEditText); 

ten może być realizowany w dowolnym miejscu wątku UI; odbiornik kliknięć, metoda onCreate i wszystko pomiędzy.

Istnieje bardziej ogólny przykład in this question i dobry przegląd tych procesów in this blog.

Użyj poniższego kodu, aby dodać edytor tekstu Programowo rozwiąże on Twój problem.

RelativeLayout.LayoutParams mRparams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); 
EditText myEditText = new EditText(context); 
myEditText.setLayoutParams(mRparams); 
mRlayout.addView(myEditText);
