<span>ZoneView是一个View实现，它创建区域，为了显示或模型/视图转换，子视图未被创建或存储，直到它们被需要为止。</span>
<span>这样，通过仅为正在被主动查看/编辑的区域构建视图对象，可以显着减少正在表示模型的情况下的内存消耗。</span>
<span>孩子的大小可以以某种方式估计，或者异步计算，只保存结果。</span>
<p> <span>ZoneView扩展BoxView以提供一个框架，为其子代码实现区域。</span> <span>这些区域是仅代表ZoneView实例负责的模型的一部分的特殊View实现（此类的实例的子项）。</span> <span>在尝试显示它们之前，区域不会创建子视图。</span> <span>盒子形状的视图非常适合这一点，因为：</span> </p>
<ul>
<li> <span>盒子是一个大量使用的视图，并且有一个提供此行为的框提供了巨大的机会将视图从视图工厂插入到视图层次结构中。</span> </li>
<li> <span>箱子沿一个方向平铺，因此很容易以可靠的方式将它们分成区域。</span> </li>
<li> <span>框通常与模型有一个简单的关系（即它们创建直接表示子元素的子视图）。</span> </li>
<li> <span>盒子比一些其他形状更容易估计尺寸。</span> </li>
</ul>
<p> <span>默认行为由两个属性maxZoneSize和maxZonesLoaded控制。</span> <span>将maxZoneSize设置为Integer.MAX_VALUE将产生仅导致一个区域的创建。</span> <span>这将有效地将视图转变为装饰器图案的实现。</span> <span>将maxZonesLaaded设置为Integer.MAX_VALUE的值将导致区域永远不会被卸载。</span> <span>为了简单起见，在视图负责的元素的子元素表示的边界上创建区域。</span> <span>区域可以是任何View实现，但默认实现基于AsyncBoxView，它有效地支持相当大的区域。</span> </p>
