How to validate Radio button for gender in android?

Hello Everybody How do I get validate my form specially for "gender", where I have used RadioButton, so that when "male" is selected "female" will automatically get unselected. Again for that will I have to take RadioButton or it'll be better to take RadioGroup? Than开发者_JAVA百科ks.

Put your gender RadioButtons inside a RadioGroup

Use RadioGroup. You can see the full documentation RadioGroup

You can refer Example from developer.android.com -> http://developer.android.com/resources/tutorials/views/hello-formstuff.html#RadioButtons

For Example in your xml file :

 <RadioGroup android:layout_height="wrap_content" android:id="@+id/gender_group"
    android:layout_width="match_parent">
    <RadioButton android:text="Male"
        android:layout_width="wrap_content" android:id="@+id/radio0"
        android:layout_height="wrap_content" android:checked="true"></RadioButton>
    <RadioButton android:text="Female"
        android:layout_width="wrap_content" android:id="@+id/radio1"
        android:layout_height="wrap_content"></RadioButton>
</RadioGroup>

try this

public void onRadioButtonClicked(View view) {
    // Is the button now checked?
    boolean checked = ((RadioButton) view).isChecked();

    // Check which radio button was clicked
    switch(view.getId()) {
        case R.id.radio_pirates:
            if (checked)
                // Pirates are the best
            break;
        case R.id.radio_ninjas:
            if (checked)
                // Ninjas rule
            break;
    }
}
