        *********** *********
        *    1    * *   2   *   // These are EditTexts 
        *********** *********

        **************************
        *   7   *   8    *   9   *   
        **************************
        *   4   *   5    *   6   *  // These are Buttons
        **************************

You want to use hasFocus() not requestFocus() because requestFocus() takes the focus away from whatever View currently has it and gives it to the caller. Also you should use a generic listener to reduce your duplicate code, like below.

Create a new class variable:

OnClickListener addClickListener = new OnClickListener() {
    public void onClick(View v) {
        int number = Integer.parseInt(((Button) v).getText().toString());
        if(inJugada.hasFocus()) { // " == true" is implied
            playDisplayed += number;
        }else if(inValor.hasFocus()) {
            numberDisplayed += number;
        }
        updateTextField();
    }
};

And add this listener to your Buttons 0-9:

final Button bt0 = (Button) findViewById(R.id.btnNum0Id);
bt0.setOnClickListener(addClickListener);

// etc.
