genderGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener(){
      public void onCheckedChanged(RadioGroup group,int chackedId){
          if (femalButton.getId() == chackedId){
              System.out.println("female");             Toast.makeText(Activity9.this,"famle",Toast.LENGTH_SHORT).show();         }         else if(maleButton.getId() == chackedId){
              System.out.println("male");         }     } }); 这个监听是用来显示男女的，其中男女是单选只能在其中选择一个，不能选择两个 swimBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){
      public void onCheckedChanged(CompoundButton buttonView,boolean isChecked){
          if (isChecked){
              System.out.println("swim is checked");         }         else {
              System.out.println("swim is unchecked");         }     } }); runBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){
      public void onCheckedChanged(CompoundButton buttonView,boolean isChecked){
          if (isChecked){
              System.out.println("run is checked");         }         else{
              System.out.println("run is unchecked");         }     } }); readBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){
      public void onCheckedChanged(CompoundButton buttonView,boolean isChecked){
          if (isChecked){
              System.out.println("read is checked");         }         else{
              System.out.println("read is unchecked");         }     } }); 这三个判断是用来判断你选择的哪一个！这三个可以多选，当你选着其中任意一个的时候都会打印出一句话如一下效果
