Solution

Output

Using RadioButton inside CardView doesn't work with RadioGroup you have to individually add each radio button in CardView and handle the check selection and de-selection manually. Try below code :

Main Layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent">
<LinearLayout
    android:id="@+id/radioGrpGender"
    android:layout_width="match_parent"
    android:orientation="vertical"
    android:layout_centerInParent="true"
    android:layout_marginTop="30dp"
    android:layout_height="wrap_content">
    <TextView
        android:id="@+id/txtGender"
        android:layout_width="match_parent"
        android:text=""
        android:gravity="center"
        android:layout_height="wrap_content"/>
    <androidx.cardview.widget.CardView
        android:layout_width="match_parent"
        android:layout_margin="5dp"
        app:cardCornerRadius="50dp"
        app:cardElevation="7dp"
        android:layout_height="50dp">
        <RadioButton
            android:id="@+id/radioMale"
            android:text="Male"
            android:paddingStart="10dp"
            android:background="@drawable/radio_flat_selector"
            android:button="@android:color/transparent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    </androidx.cardview.widget.CardView>
    <androidx.cardview.widget.CardView

        android:layout_width="match_parent"
        android:layout_margin="5dp"
        app:cardCornerRadius="50dp"
        android:layout_height="50dp">
        <RadioButton
            android:id="@+id/radioFemale"
            android:text="Female"
            android:paddingStart="10dp"
            android:background="@drawable/radio_flat_selector"
            android:button="@android:color/transparent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    </androidx.cardview.widget.CardView>
    <androidx.cardview.widget.CardView
        android:layout_width="match_parent"
        android:layout_margin="5dp"
        app:cardCornerRadius="50dp"
        android:layout_height="50dp">
        <RadioButton
            android:id="@+id/radioOther"
            android:text="Other"
            android:paddingStart="10dp"
            android:background="@drawable/radio_flat_selector"
            android:button="@android:color/transparent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    </androidx.cardview.widget.CardView>
</LinearLayout>

radio_flat_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/radio_flat_selected" 
 android:state_checked="true" />
<item android:drawable="@drawable/radio_flat_regular" />

radio_flat_selected.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:shape="rectangle">
  <corners android:radius="1dp" />
  <solid android:color="#D2FFDF" />

 <shape xmlns:android="http://schemas.android.com/apk/res/android"

 </shape>

Main Java Code:

public class YourActivityName extends AppCompatActivity implements CompoundButton.OnCheckedChangeListener {


private RadioButton radioMale;
private RadioButton radioFemale;
private RadioButton radioOther;
private TextView txtGender;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_layout_nanme);

    radioMale = findViewById(R.id.radioMale);
    radioFemale = findViewById(R.id.radioFemale);
    radioOther = findViewById(R.id.radioOther);
    txtGender = findViewById(R.id.txtGender);

    radioMale.setOnCheckedChangeListener(this);
    radioFemale.setOnCheckedChangeListener(this);
    radioOther.setOnCheckedChangeListener(this);

}


@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

    if (isChecked) {
        txtGender.setText(buttonView.getText().toString());
        if (R.id.radioMale == buttonView.getId()) {
            radioFemale.setChecked(false);
            radioOther.setChecked(false);
        } else if (R.id.radioFemale == buttonView.getId()) {
            radioMale.setChecked(false);
            radioOther.setChecked(false);
        } else {
            radioFemale.setChecked(false);
            radioMale.setChecked(false);
        }
    }
  }
}
