好记性不如烂笔杆android学习笔记<三> RadioGroup 和 CheckBox的使用

8，//RadioGroup 和 CheckBox的使用
xml文件中：

<RadioGroup 
        android:id="@+id/genderGroup"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        
        <RadioButton 
            android:id="@+id/femaleButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/female"/>
        <RadioButton 
            android:id="@+id/maleButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/male"/>
    </RadioGroup>
    <CheckBox 
        android:id="@+id/swim"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/swimBox"
        />
    <CheckBox 
        android:id="@+id/run"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/runBox"
        />
    <CheckBox 
        android:id="@+id/read"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/readBox"
        />

Java文件中

//为RadioButton添加监听器，一组按钮对应一个监听器
        genderGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                if(famaleButton.getId() == checkedId){
                    System.out.println("famale");
                    Toast.makeText(RadioTest.this, "famale", Toast.LENGTH_SHORT).show();
                }
                else if(maleButton.getId() == checkedId){
                    System.out.println("male");
                    Toast.makeText(RadioTest.this, "male", Toast.LENGTH_SHORT).show();
                }
            }
        });
//为多选框添加监听器，每个checkbox对应一个监听器
        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");
                }
            }
        });
    }
