I am new to android development and I am making a simple calculator. I have a editText field and the basic UI of a normal calculator. When I click the button "1" and then click button to display "+", the "1" displayed in the editText field is overwritten by "+". I want to keep adding text, for example, "1+2/3".

In Java code you have to keep String reference of your edit text's value and everytime you press the button, you append that button value to the String value.
Pseudo code:
String value = editText.geText().toString();

// image that you click "+" button
value = value.append("+");
editText.setText(value);
