public class RadioContainer
extends DirectionalLayout创建一组表示一系列独占选项的单选按钮。
选择单选组中的一个单选按钮将自动取消选择同一组中的其他单选按钮。 默认情况下，取消选择组中的所有单选按钮。 无法取消选择已选择的单选按钮，但可以清除单选组以取消该单选按钮的选中状态。

字段详细信息
INVALID_ID
public static final int INVALID_ID
表示无效的 id。
使用此值可清除单选组中所有单选按钮的选定状态。 见标记（int）。
mMarkListener
protected RadioContainer.CheckedStateChangedListener mMarkListener
指示单选组中单选按钮更改事件的侦听器。
构造函数详细信息
RadioContainer
public RadioContainer(Context context)
用于使用默认属性集和样式创建 RadioContainer 实例的默认构造函数。
参数：
| 参数名称 | 参数描述 |
|---|---|
| context | 指示应用程序上下文。 |
RadioContainer
public RadioContainer(Context context, AttrSet attrSet)
用于在 XML 文件解析后使用指定的属性集和默认样式创建 RadioContainer 实例的构造函数。
参数：
| 参数名称 | 参数描述 |
|---|---|
| context | 指示应用程序上下文。 |
| attrSet | 指示要使用的属性集。 |
RadioContainer
public RadioContainer(Context context, AttrSet attrSet, String styleName)
用于在 XML 文件解析后使用指定的属性集和指定样式创建 RadioContainer 实例的构造函数。
参数：
| 参数名称 | 参数描述 |
|---|---|
| context | 指示应用程序上下文。 |
| attrSet | 指示要使用的属性集。 |
| styleName | 指示要使用的样式名称。 |
方法详情
mark
public void mark(int id)
选择其 ID 在参数中传递的单选按钮。
单选组中的每个单选按钮都有一个 ID，范围从 0 到 n-1。 单选按钮 ID 与 Component#getId() 中的不同。 如果单选按钮 ID 为 INVALID_ID，则该组中所有单选按钮的选中状态都是清除的，相当于 cancelMarks()。
参数：
| 参数名称 | 参数描述 |
|---|---|
| id | 指示要选择的单选按钮的 ID。 |
Throws:
| Throw名称 | Throw描述 |
|---|---|
| IllegalArgumentException | 如果参数值小于 INVALID_ID，则引发此异常。 |
Since:
4
getMarkedButtonId
public int getMarkedButtonId()
获取单选组中选中单选按钮的ID。
ID 范围从 0 到 n-1。 如果取消选择单选组中的所有按钮，则 ID 为 INVALID_ID。
返回:
返回所选单选按钮的 ID。
Since:
4
cancelMarks
public void cancelMarks()
清除单选组中所有单选按钮的选定状态。
这样，单选组中的所有按钮都被取消选择。
Since:
4
setMarkChangedListener
public void setMarkChangedListener(RadioContainer.CheckedStateChangedListener listener)
为单选容器中单选按钮的更改事件设置侦听器。
当单选按钮的状态从取消选中变为选中时使用此方法，反之亦然。 它通知单选按钮的更改事件并调用 RadioContainer.CheckedStateChangedListener#onCheckedChanged(RadioContainer, int) 来处理更改事件。
参数：
| 参数名称 | 参数描述 |
|---|---|
| listener | 指示单选组中单选按钮更改事件的侦听器。 |
Since:
4
getMarkChangedListener
public RadioContainer.CheckedStateChangedListener getMarkChangedListener()
获取监听此 RadioContainer 中单选按钮更改事件的监听器。
返回:
返回获取的监听器。
