Android开发第四次作业

Java代码：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.content_main);
    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);
    genderGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {
            if (femaleButton.getId() == checkedId) {
                System.out.println("female");
                //Toast.makeText(MainActivity.this,"female",Toast.LENGTH_SHORT).show();
            } else if (maleButton.getId() == checkedId) {
                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，不能同时选择两个。

swimBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    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() {
    @Override
    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() {
    @Override
    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，当你选择其中任意一个的时候都会打印出一句话如一下效果：

10-29 18:07:21.570 1535-1535/com.example.administrator.myapplication I/System.out: swim is checked
10-29 18:07:22.458 1535-1535/com.example.administrator.myapplication I/System.out: run is checked
10-29 18:07:24.146 1535-1535/com.example.administrator.myapplication I/System.out: read is checked

显示出来的软件效果：
