    Radio Button
    A radio button is a two-states button that can be either checked or unchecked. They are normally used together in a RadioGroup. When several radio buttons live inside a radio group, checking one radio button unchecks all the others.
    Exmaple:-

    First create a layout

    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout&#95;width="match&#95;parent"
        android:layout&#95;height="wrap&#95;content"
        android:orientation="vertical"
        android:padding="5dp" >
   <RadioGroup
            android:id="@+id/genderRadioGroup
            android:layout&#95;width="match&#95;parent"
            android:layout&#95;height="wrap&#95;content"
            android:orientation="vertical" >
         <RadioButton
                android:id="@+id/male"
                android:layout&#95;width="wrap&#95;content"
                android:layout&#95;height="wrap&#95;content"
                android:text="Male" />

            <RadioButton
                android:id="@+id/female"
                android:layout&#95;width="wrap&#95;content"
                android:layout&#95;height="wrap&#95;content"
                android:text="Female" />
   </RadioGroup>
 <Button
            android:id="@+id/knowGender"
            android:layout&#95;width="wrap&#95;content"
            android:layout&#95;height="wrap&#95;content"
            android:layout&#95;gravity="center&#95;horizontal"
            android:layout&#95;marginTop="5dp"
            android:text="Know Gender" />
</LinearLayout>
