Can't draw editText in android canvas

Question

I am trying to add an editText box to my android project. This project is done almost entirely with Java (barely any xml), so I would like to know how to get this done in Java. My current implementation which is getting a runtime error is as follows:

public class MainMenu extends View{
    EditText editText;

    public MainMenu(Context context) {
        super(context);
        EditText editText = new EditText(context);
        editText.setDrawingCacheEnabled(true);
        editText.setText("My Text");
        editText.setWidth(180);         
        editText.setBackgroundColor(Color.WHITE);
    }
    @Override
    protected void onDraw(Canvas canvas){
        super.onDraw(canvas);
        editText.draw(canvas);
        invalidate();
    }
}

Can anyone point out what is wrong and possibly offer a solution using Java?

EditText is view. You are trying to draw view inside view. Wtf? — Divers, Dec 01 '15 at 22:44
I am trying to add a textbox that when clicked it would open up a number screen so that you can enter numbers. Googling how to do this led me to a topic that recommended using EditText. How else should I approach this then? — user3858843, Dec 01 '15 at 22:56

EditText editText = new EditText(context);

Your "editText" will be null in the onDraw method i think

editText = new EditText(context);

Please let us know when u resolved it

I'm dumb for not noticing that. That stopped the runtime error. Now I'm having the problem of not seeing anything. Tried setting the editText visibility, enabling the requestFocus, setting a height/position. Nothing I add is making it visible. – user3858843 Dec 01 '15 at 23:18
You should read on how views work. Now you should probable accept this answer because your first question is why do you have an exception thrown. – Dec 01 '15 at 23:23

I think you should use:

EditText text = (EditText) findViewById(R.id.editTextId);

You can find this in the top-right of the design xml file. Good luck!
