1. FlexBox布局控件

FlexBox布局控件经常用在页面的布局。

1.1 alignItems 对齐模式

• 常用的有Start，Center，End
  
• View

	<PanelheaderText="alignItems 对齐模式"class="sapUiLargeMarginBottom"><HBox><Panel headerText="Start"><FlexBoxalignItems="Start"class="borderStyle"width="220px"height="100px"><Buttontext="1"type="Emphasized"class="sapUiTinyMarginEnd"/><Buttontext="2"type="Reject"class="sapUiTinyMarginEnd"/><Buttontext="3"type="Accept"class="sapUiTinyMarginEnd"/></FlexBox></Panel><Panel headerText="Center"><FlexBoxalignItems="Center"class="borderStyle"width="220px"height="100px"><Buttontext="1"type="Emphasized"class="sapUiTinyMarginEnd"/><Buttontext="2"type="Reject"class="sapUiTinyMarginEnd"/><Buttontext="3"type="Accept"class="sapUiTinyMarginEnd"/></FlexBox></Panel><Panel headerText="End"><FlexBoxalignItems="End"class="borderStyle"width="220px"height="100px"><Buttontext="1"type="Emphasized"class="sapUiTinyMarginEnd"/><Buttontext="2"type="Reject"class="sapUiTinyMarginEnd"/><Buttontext="3"type="Accept"class="sapUiTinyMarginEnd"/></FlexBox></Panel></HBox></Panel>

1.2 justifyContent 对齐模式

1.7 组件等高显示

• View

  <PanelheaderText="组件等高"class="sapUiLargeMarginBottom"><HBox class="sapUiLargeMarginBottom customPanel"><FlexBox><Texttext="Although they have different amounts of text, both columns are of equal height."><layoutData><FlexItemDatagrowFactor="1"baseSize="0"backgroundDesign="Solid"styleClass="sapUiTinyMargin"/></layoutData></Text><Texttext="Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

2. HBox,VBox

HBox,VBox是FlexBox的子类，可以直接使用并实现横向布局和竖向布局

• View

   <PanelheaderText="HBox  VBox"class="sapUiLargeMarginBottom"><HBox><Panel headerText="HBox"><HBoxclass="borderStyle"width="220px"height="100px"><Buttontext="1"type="Emphasized"class="sapUiTinyMarginEnd"/><Buttontext="2"type="Reject"class="sapUiTinyMarginEnd"/><Buttontext="3"type="Accept"class="sapUiTinyMarginEnd"/></HBox></Panel><Panel headerText="VBox"><VBoxclass="borderStyle"width="220px"height="100px"><Buttontext="1"type="Emphasized"class="sapUiTinyMarginEnd"/><Buttontext="2"type="Reject"class="sapUiTinyMarginEnd"/><Buttontext="3"type="Accept"class="sapUiTinyMarginEnd"/></VBox></Panel></HBox></Panel>

3. HorizontalLayout，VerticalLayout

这两个组件类似与HBox和VBox，主要区别是HorizontalLayout无法设置宽高属性，VerticalLayout无法设置高属性

• View

	<PanelheaderText="HorizontalLayout,VerticalLayout"class="sapUiLargeMarginBottom"><HBox><Panel headerText="HorizontalLayout"><l:HorizontalLayoutclass="borderStyle"><Buttontext="1"type="Emphasized"class="sapUiTinyMarginEnd"/><Buttontext="2"type="Reject"class="sapUiTinyMarginEnd"/><Buttontext="3"type="Accept"class="sapUiTinyMarginEnd"/></l:HorizontalLayout></Panel><Panel headerText="VerticalLayout"><l:VerticalLayoutclass="borderStyle"width="220px"><Buttontext="1"type="Emphasized"class="sapUiTinyMarginEnd"/><Buttontext="2"type="Reject"class="sapUiTinyMarginEnd"/><Buttontext="3"type="Accept"class="sapUiTinyMarginEnd"/></l:VerticalLayout></Panel></HBox></Panel>
