2, 为什么我要写这样一个框架。

自Google2015 io 大会后google官方出了一个数据绑定框架(虽然它目前有些问题).

它的工作原理是通过在layout 文件中数据绑定的配置，使得会在java中少写些代码，以达到类似javaweb端数据绑定的效果。

但是个人人为在layout中写数据绑定的东西不好。为什么呢？因为那样会使得layout文件的可读性大受影响。在javaweb的时候我就深深的体会到了,

不同的工作就该分别放置所以我很厌恶这种方式。and我写的这个框架配置文件主要在另一个文件夹下res/raw目录下。

3, 本框架特点及介绍

支持常用的数据绑定。比如图片，文字，文字颜色等。以及adapter数据的绑定。自定义属性，自定义事件.

<code class="hljs java has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">表达式expression 支持java 方法，字段，数组的调用 (包括任意嵌套), 支持dp, sp （eg: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'12dp'</span>）,
支持#颜色(eg: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"#ff0000"</span>) , 支持当前项目资源的引用 (eg: (<span class="hljs-annotation" style="color: rgb(155, 133, 157); box-sizing: border-box;">@dimen</span>/corner_size)或 R.drawable.ic_default ),
不支持赋值表达式。
Ps: 注意调用的过程中不要忘记xml中申明<variable> 和 <<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">import</span>> 下面会介绍。</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

1) 数据绑定xml配置文件的介绍

Root节点为 < DataBinding>.

@(1) DataBinding 子节点 < data> : 用于导入class和声明一个变量的类型。 eg:

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;">这个定义了一个变量 imageParam, 它的classname 为<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">com</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.heaven</span>7<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.databinding</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.demo</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.samples</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.RoundImageBindTest</span>$ImageParam,  eventHanlder同理。

Import节点: 表示导入了一个类，一般是静态方法或字段调用的时候使用。比如使用上面这个import后， 你就可以简单的使用Test<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.xxx</span> 常量和静态方法了。
variable节点: type属性 表示是java bean还是callback.   Callback用于事件的绑定，必须定义. </code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

@(2), 子节点< bind>

这个节点一般是所有属性绑定property/imageProperty的父节点。它有2个属性，id和referVariable. 这2个属性一般是互斥的。所以不要同时使用.

<code class="hljs http has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-attribute" style="box-sizing: border-box;">id属性</span>: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">表示android view id的引用.  比如R.id.listview. 那么 id 就为 listview.</span>
<span class="hljs-attribute" style="box-sizing: border-box;">referVariable</span>: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;"> 表示引用变量对应的对象</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>

它有2种适用方式：

第一种,

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><bind <span class="hljs-property" style="box-sizing: border-box;">id</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"bt"</span>>
<<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"text"</span> referVariable=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"user"</span> valueType=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"string"</span>>@{user.username}</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span>>
<<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"textColor"</span> referVariable=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"user"</span> >user.male ? {@color/red} : {@color/random}</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span>>
</bind></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

表明将绑定属性text和textColor的值到 id为bt的控件上。

第2种:

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><bind referVariable=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"user"</span>>
<<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span> <span class="hljs-property" style="box-sizing: border-box;">id</span> =<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"bt2"</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"text"</span> >@{user.username}</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span>>
<<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span> <span class="hljs-property" style="box-sizing: border-box;">id</span> =<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"bt3"</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"text"</span> >user.getNickname()</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span>>
</bind></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

表示将表达式 user.username的值绑定到控件id = bt2 的 text属性上

将表达式 user.getNickname()的值绑定到控件id = bt3 的 text属性上

@(3) , bind子节点 < property>

它含有属性 id, name, referVariable.

id:

表示控件的id名称。
name:

表示要绑定的属性。
referVariable:

表示引用的变量

其中name是必须有的属性， referVariable是可选的。Id也是可选因为可以在bind元素节点声明id属性.

到此 android-databinding的基本绑定配置元素已说完。

@(4) , 绑定adapter的父节点 < bindAdapter>

含有属性： id, referVariable, selectMode

id :

表示要绑定adapter的控件id
referVariable

表示引用变量
selectMode

表示adapter item的选择模式，单选1 ，多选2

此属性是配合 ISelectable接口使用的。所以 referVariable引用 Bean Class必须实现 ISelectable接口。关于选择模式稍后将细作说明。

bindAdapter子节点 < item>

用于绑定1种或多种item， 1个item节点表示1种item, 以此类推。它有3个属性.

layout, tag , referVariable.

Layout:

表示当前item绑定的layout id. ，必须
referVariable

表示引用变量，可选
tag

表示给Item打一个1标签, 在多item布局时必须, 此时bean 的class 必须实现 ITag接口。

Item节点下的 < property>

这个节点下的 property 将作用于item的根布局上，所以是不用申明id属性的。只要name属性以及表达式即可。比如：

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><<span class="hljs-property" style="box-sizing: border-box;">item</span> layout=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"item_xxx"</span> tag = <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"1"</span> referVariable=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"itemHandler"</span>>
<propertyname=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"onLongClick"</span>>itemHandler.onItemLongClick(user)</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span>>

<<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"onClick"</span> >itemHandler.onItemClick(user)</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span>>
</<span class="hljs-property" style="box-sizing: border-box;">item</span>></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

即给这个item的根布局添加2个事件。onClick 和 onLongClick .

关于item 其他view 绑定等同于< bind> 节点的说明.

图片属性的绑定. < imageProperty>介绍.

含有3个属性： id, type, referVariable 和 roundSize，borderWidth，borderColor，url，default，errorResId 6个子节点。

type

只有3个值， round/oval/circle其他属性之前类似的说过了，我就不再说了。

roundSize :

圆角大小只有在type = “round”时有效.
borderWidth:

边框宽度
borderColor:

边框颜色
url

网络图片地址
default

默认图片。支持 drawable ,bitmap, resource id
errorResId

只支持图片iresource id类型。

3) 绑定自定义属性（view child）说明

含义：绑定一个自定义的属性到指定的控件(view 子类) 上。

如何使用？

类似java bean.比如事件名称为 user. 那么一定要有对应的方法： setUser，

参数可以接收表达式的值即可.

4), 事件绑定详细说明.（包含自定义）

比如你要绑定onClickUser的方法到 onClick事件上。那么data-binding的 property配置如下:

<code class="hljs applescript has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span> <span class="hljs-property" style="box-sizing: border-box;">name</span>=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"onClick"</span> referVariable=<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"user,mainHanlder"</span> >mainHanlder. onClickUser(user)</<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">property</span>></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

对应的对象绑定的方法如下：

<code class="hljs cs has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">void</span> <span class="hljs-title" style="box-sizing: border-box;">onClickUser</span> (View v,User user)</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

@(1), 事件绑定到的对象方法, 参数说明

事件的第一个参数一定是 View类型. 自定义的参数都是按顺序放置在最末尾的。示例：

比如我要监听EditText 文本变化的onTextChanged. 原本android sdk的标准参数是 (CharSequence s, int start, int count, int after)

而在本框架中对应onTextChanged的方法参数是这样的：

(View v, CharSequence s, int start, int before, int count)

名字可任意写, 对应即可 .

@(2) adapter中item事件绑定的不同之处

为了方便大家的使用我封装好了一个标准的item内的事件参数类型。当然同样支持

传递其他对象，按顺序放置于末尾，你需要在data-binding的xml中配置。

<code class="hljs lisp has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-list" style="box-sizing: border-box;">(<span class="hljs-title" style="box-sizing: border-box; color: rgb(0, 0, 136);">View</span> v, Integer position,ImageInfo item, AdapterManager<?> am)</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

第1个参数代表绑定该事件的view,

第2个参数表示item的position属性

第3个参数表示数据的 bean对象。你绑定的什么类型就写什么类型。

第4个参数是AdapterManager , 这个对象是做什么的呢？
答案就是方便notifyDataSetChanged()等方法的调用. 当然还有操作选择状态的SelectHelper （支持单选,多选）. 和 IHeaderFooterManager. 通过get方式可以获取。

IHeaderFooterManager 目前只适用于 RecyclerView的adapter.

AdapterManager 如图：

它除了notifyXxx方法外还提供了 ‘crud’item 数据的方法。这些是会自动调用notify的。所以你不用额外调用了。

@(3), 自定义事件注册器

ListenerFactory 这个类主要是注册事件的，如下这个，默认已经注册好了OnClick ,OnLongClick .Text改变监听

<code class="hljs java has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">static</span>{
sRegistedListenerMap = <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">new</span> SparseArray<String>();

registEventListener(PropertyNames.ON_CLICK      , OnClickListenerImpl.class);
registEventListener(PropertyNames.ON_LONG_CLICK , OnLongClickListenerImpl.class);
registEventListener(PropertyNames.TEXT_CHANGE  , TextWatcherImpl.OnTextChangeImpl.class);
registEventListener(PropertyNames.TEXT_CHANGE_AFTER  , TextWatcherImpl.AfterTextChangeImpl.class);
registEventListener(PropertyNames.TEXT_CHANGE_BEFORE, TextWatcherImpl.BeforeTextChangeImpl.class);

}

<span class="hljs-javadoc" style="color: rgb(136, 0, 0); box-sizing: border-box;">/** the class clazz must have empty constructor */</span>
<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">static</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">void</span> <span class="hljs-title" style="box-sizing: border-box;">registEventListener</span>(String propertyName,Class<?> clazz){
sRegistedListenerMap.put(propertyName.hashCode(),clazz.getName());
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li><li style="box-sizing: border-box; padding: 0px 5px;">12</li><li style="box-sizing: border-box; padding: 0px 5px;">13</li><li style="box-sizing: border-box; padding: 0px 5px;">14</li><li style="box-sizing: border-box; padding: 0px 5px;">15</li></ul>

@(4) 关于事件和属性绑定的方法最好都不要重载，否则很可能绑定数据失败.

Ps: 本来onLongClick事件的返回值一定是boolean 类型，但我为了大家方便。

OnLongClick事件绑定的返回值可以为 void哦（相当于true –> 消耗掉事件）。

4, 调用api说明

调用的入口api 均在 IDataBinder中声明. 下面是简要说明，具体见github. 实现类DataBinder.

<code class="hljs java has-numbering" style="display: block; padding: 0px; background-color: transparent; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-top-left-radius: 0px; border-top-right-radius: 0px; border-bottom-right-radius: 0px; border-bottom-left-radius: 0px; word-wrap: normal; background-position: initial initial; background-repeat: initial initial;"><span class="hljs-javadoc" style="color: rgb(136, 0, 0); box-sizing: border-box;">/**

选择模式帮助类->SelectHeper说明, 方法如下图:

这个用于搭配实现了ISelectable接口的bean对象。在本框架中是必须的。

这内部都是会自动调用notify, 除方法clearSelectedPositions().

只适用于单选模式的方法：

只适用于多选模式的方法

单选多选均适用的方法：
