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

<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"
/>

//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");
}
}
});
}
