java代碼

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");
        }
    }
});
這個監聽是用來顯示男女的，其中男女是單選只能在其中選擇一個，不能選擇兩個
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");
        }
    }
});
這三個判斷是用來判斷你選擇的哪一個！這三個可以多選，當你選著其中任意一個的時候都會列印出一句話如一下效果
