1、radioGroup:  这个组只能选择其中一个。
 <RadioGroup
android:id="@+id/genderGroup"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical"
    >
    <RadioButton    // 一个组里面有两个button,如男
    android:id="@+id/femaleButton"
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/female"
     />
    <RadioButton   // 如女， 
    android:id="@+id/maleButton"
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/male"
     />
</RadioGroup>

2、checkBox: 这个都可以选
<CheckBox
android:id="@+id/swim"
 android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:text="@string/swim"
  />
<CheckBox
android:id="@+id/run"
 android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:text="@string/run"
  />
<CheckBox
android:id="@+id/read"
 android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:text="@string/read"
  />


3、先声明：
private RadioGroup genderGroup = null;
private RadioButton femaleButton = null;
private RadioButton maleButton = null;
private CheckBox swimBox = null;
private CheckBox runBox = null;
private CheckBox readBox = null;

4、在onCreate里面 初始化：
 genderGroup = (RadioGroup)findViewById(R.id.genderGroup);
 femaleButton = (RadioButton)findViewById(R.id.femaleButton);
 maleButton = (RadioButton)findViewById(R.id.maleButton);
 swimBox = (CheckBox)findViewById(R.id.swim);
  runBox = (CheckBox)findViewById(R.id.run);
  readBox = (CheckBox)findViewById(R.id.read);

5、Radio 组设置一个监听器：

genderGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {  //当radio里面的选择改变时，就会进入这里。
  @Override
   public void onCheckedChanged(RadioGroup group, int checkedId) {
        // TODO Auto-generated method stub
        if(femaleButton.getId() == checkedId){ 
                   System.out.println("famale");
                    Toast.makeText(RadioTest.this, "famle", Toast.LENGTH_SHORT).show();
           }
        else if(maleButton.getId() == checkedId)
        {
                    System.out.println("male");
        }
    }
});


6、checkbox 分别设置监听器：
       //为多选按钮添加监听器
 swimBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {            // 单swimBox点击的时候，无论是打勾还是去掉勾

    @Override
     public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        // TODO Auto-generated method stub
        if(isChecked)              //打勾
        {
                System.out.println("swim is checked");
        }
        else                         //去掉勾
        {
                System.out.println("swim is unchecked");
        }
    }
});


 runBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
         // TODO Auto-generated method stub
                if(isChecked)
                {
                        System.out.println("run is checked");
                }
                else
                {
                        System.out.println("run is unchecked");
                }
           }
});
