**layout文件：**

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        tools:context=".MainActivity" >
    
        <TextView
            android:id="@+id/label"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Type here:" />
    	
        <RadioGroup 
            android:id="@+id/genderGroup"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@id/label"
            android:orientation="horizontal"
            >
            <RadioButton 
                android:id="@+id/femaleButton"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="female"
    android:button="@null"
                android:drawableRight="@android:drawable/btn_radio"
                />  
            <RadioButton 
                android:id="@+id/maleButton"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="male"
                />
        </RadioGroup>
        
        <CheckBox 
            android:id="@+id/swim"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="swim"
            android:layout_below="@id/genderGroup"
            android:layout_alignParentRight="true"
            />
        
        <CheckBox 
            android:id="@+id/run"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="run"
            android:layout_toLeftOf="@id/swim"
            android:layout_alignTop="@id/swim"        />
        
    </RelativeLayout>

**为radioGroup和checkbox添加监听器：**

protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            
            genderGroup = (RadioGroup) findViewById(R.id.genderGroup);
            
            genderGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
    			
    			@Override
    			public void onCheckedChanged(RadioGroup rg, int chId) {
    				
    				// -----Toast的用法
    				Toast.makeText(MainActivity.this, "female", Toast.LENGTH_SHORT).show();
    				
    			}
    		});
            
            
            ((CheckBox)findViewById(R.id.run)).setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    			
    			@Override
    			public void onCheckedChanged(CompoundButton arg0, boolean arg1) {
    				System.out.println(arg1);
    			}
    		});
            
        }
