20     @Override
21     protected void onCreate(Bundle savedInstanceState) {
22         super.onCreate(savedInstanceState);
23         setContentView(R.layout.activity_main);
24

29         cbBasketBall=(CheckBox)super.findViewById(R.id.basketball);
30         //在GenderGroup注册OnCheckedChangeListener事件
31                   GenderGroup.setOnCheckedChangeListener(new GenderOnCheckedChangeListener());
32                   //在cbFootBall注册OnCheckedChangeListener事件
33         cbFootBall.setOnCheckedChangeListener(new BootBallOnCheckedChangeListener());
34                   //在cbBasketBall注册OnCheckedChangeListener事件
35 
36         cbBasketBall.setOnCheckedChangeListener(new BasketBallOnCheckedChangeListener());
37     }
38     
39     private class GenderOnCheckedChangeListener implements OnCheckedChangeListener{
40         @Override
41         public void onCheckedChanged(RadioGroup group,int checkedId){
42             String sGender="";
43             if(rbFemale.getId()==checkedId){
44                 sGender=rbFemale.getText().toString();
45             }
46             if(rbMale.getId()==checkedId){
47                 sGender=rbMale.getText().toString();
48             }
49             Toast.makeText(getApplicationContext(), "您选择的性别是："+sGender, Toast.LENGTH_LONG).show();
50         }
51         
52     }
53     
54     private class BootBallOnCheckedChangeListener implements CompoundButton.OnCheckedChangeListener{
55         @Override
56         public void onCheckedChanged(CompoundButton button, boolean isChecked){
57             String sFav="";
58             if(isChecked){
59                 sFav=cbFootBall.getText().toString();
60                 sFav=sFav+"选中！";
61             }
62             else
63                 sFav=sFav+"未迁中";
64             Toast.makeText(getApplicationContext(), "您选择的爱好是："+sFav, Toast.LENGTH_LONG).show();
65         }
66     }
67     
68     private class BasketBallOnCheckedChangeListener implements CompoundButton.OnCheckedChangeListener{
69         @Override
70         public void onCheckedChanged(CompoundButton button,boolean isChecked){
71             String sFav="";
72             if(cbBasketBall.isChecked()){
73                 sFav=cbBasketBall.getText().toString();
74                 sFav=sFav+"选中！";
75             }
76             else
77                 sFav=sFav+"未迁中";
78             Toast.makeText(getApplicationContext(), "您选择的爱好是："+sFav, Toast.LENGTH_LONG).show();
79         }
80     }
81     
82 }
管单选按钮和复选框都有OnCheckedChange事件，但注意二者区别。
　　效果如下：
