Answer 1

Использование RadioGroup для RadioButton

Answer 2

<?xml version="1.0" encoding="utf-8"?> 
<RadioGroup xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical"> 
    <RadioButton android:id="@+id/radio_pirates" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/pirates" 
     android:onClick="onRadioButtonClicked"/> 
    <RadioButton android:id="@+id/radio_ninjas" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/ninjas" 
     android:onClick="onRadioButtonClicked"/> 
</RadioGroup> 

кнопка включения радио нажмите

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; 
    } 
} 

Answer 3

Вы можете проверить программно если RadioButton проверяется, и снимите его перед проверкой на выбранный с помощью radiobutton1.isChecked() в для цикла.
