using same value for radioButton when posting to firestore

问题

I have a 2 radioButtons in my layout. One is for yes and the other is for no when asked if insured or not. When I click my save button and the data posts to firestore, it shows both NO INSURED and YES INSURED. The way I have my code set up is why it's that way but what I want to do is have one source where if the person clicks yes or no then in firestore I will have Insured : Yes or Insured : No. I will post my code down below

First thing first,

When I click my save button and the data posts to firestore

This is not happening according to your code. You should use OnClickListener method to implement your thought. I suggest going through this documentation.

---

Second thing second,

Hope, you are using RadioGroup for your RadioButton. That won't allow more than one RadioButton to be selected at a single time. Here is how you can implement RadioGroup.

---

Last thing last,

Use a single key to store a boolean value instead of storing multiple key-value pairs for RadioButton state in Firestore. Try this :

if (radioGroup.getCheckedRadioButtonId() == R.id.yesRadioButton){
    myMap.put("isInsured", true);
} else {
    myMap.put("isInsured", false);
}

instead of this :

myMap.put(KEY_YES_INSURED, yes_button);
myMap.put(KEY_NO_INSURED, no_button);

If you do all the mentioned steps correctly your database should store one value for your RadioButton states. Try and let us know if this worked or not.
