How can I check only one radiobutton in two groups if I have two radiogroups with radiobuttons

Question

I have two horizontal radiogroups with radiobuttons and I want to check only one of the radiobuttons but since they are in different radiogroups it allows the radiobutton from the other group to be checked too!Is there any way that when I check only one radiobutton from both groups?

Here is the code below:

<RadioGroup
        android:id="@+id/rgSatisfied"
        android:visibility="invisible"

So you want one button to be clicked out of six? Or row wise one? — Karan Mehta, Aug 30 '22 at 13:15
yes one out of 6,but since there are two radiogroups if you click on another one then you are able to have two radiobuttons clicked and I do not want to allow that in my app — rrezz, Aug 30 '22 at 13:18
there was no other way to have two rows with radiobuttons other than linear layout which was even worse than radiogroup cuz it allowed all of them to be clicked — rrezz, Aug 30 '22 at 13:20
You can use recyclerview if it is the only thing that you want. — Karan Mehta, Aug 30 '22 at 13:21
Or else you can add manual condition in your code to remove selection of other group's radio button if it is checked — Karan Mehta, Aug 30 '22 at 13:22
Share you Java/Kotlin code here also, I will help you do this. — Karan Mehta, Aug 30 '22 at 13:24
RadioGroup rg1 = findViewById(R.id.rg1); RadioGroup rg2 = findViewById(R.id.rg2); rg1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { rg2.clearCheck(); } }); I tried this one but it didn't work — rrezz, Aug 30 '22 at 13:30
It's a big project so I can't add all the code but I am interested in only this part — rrezz, Aug 30 '22 at 13:34

You can solve your problem by listening to changes to both RadioGroups.

When a RadioButton in one RadioGroup is checked, just un-check all RadioButtons in the second RadioGroup. This is tricky, as the un-checking triggers the listener again, crashing your app. In order to prevent that, you have to add an additional condition: That the RadioButton that triggered the event got checked, not un-checked.

Here's the code:

val groupOne = findViewById<RadioGroup>(R.id.radio_group_one)
val groupTwo = findViewById<RadioGroup>(R.id.radio_group_two)

val checkedChangeListener =
    RadioGroup.OnCheckedChangeListener { group, checkedId ->
        val checkedButton = group.findViewById<RadioButton>(checkedId)
        if (group == groupOne && checkedButton?.isChecked == true) {
            groupTwo.clearCheck()
        }
        if (group == groupTwo && checkedButton?.isChecked == true) {
            groupOne.clearCheck()
        }
    }

groupOne.setOnCheckedChangeListener(checkedChangeListener)
groupTwo.setOnCheckedChangeListener(checkedChangeListener)

this one helped a lot even tho it's not exactly working the way I wanted it to — rrezz, Aug 30 '22 at 15:21
