Always check if getText() returns null, you can use TextUtils.isEmpty(string) for convenience.

Also, Integer.parseInt(string) may throw an exception, should be handled with something like this, or just show an error with a Toast.

public static int parseWithDefault(String number, int defaultVal) {
  try {
    return Integer.parseInt(number);
  } catch (NumberFormatException e) {
    return defaultVal;
  }
}

EDIT

Taking a closer look, it seems the actual issue is that you're using .setText(int), but that int refers to a resource id, not to a value you want to display.

int output = 1234;
OutPut.setText(output);

For displaying a value, it should always be a String. Use String.valueOf(…) to convert an item to its String representation.

int output = 1234;
OutPut.setText(String.valueOf(output));

my app is crashing as soon I click add button
