How to add margin to a Button at run time?

由 ⅰ亾dé卋堺 提交于 2019-12-08 15:11:45
问题 I have to add more than one buttons on a LinearLayout. But I want to put those buttons say 5px apart. I could not find a way to set a margin of a Button.

BFC和IFC

Box: CSS布局的基本单位 　　Box 是 CSS 布局的对象和基本单位， 直观点来说，就是一个页面是由很多个 Box 组成的。元素的类型和 display 属性，决定了这个 Box 的类型。 不同类型的 Box， 会参与不同的 Formatting Context（一个决定如何渲染文档的容器），因此Box内的元素会以不同的方式渲染。让我们看看有哪些盒子： BFC 快级格式化上下文 block-level box:display 属性为 block, list-item, table 的元素，会生成 block-level box。并且参与 block fomatting context； （块元素参与BFC） IFC 内联格式化上下文 inline-level box:display 属性为 inline, inline-block, inline-table 的元素，会生成 inline-level box。并且参与 inline formatting context； （行内元素参与IFC） run-in box: css3 中才有， 这儿先不讲了。 Formatting context 是 W3C CSS2.1 规范中的一个概念。 它是页面中的一块渲染区域，并且有一套渲染规则，它决定了其子元素将如何定位，以及和其他元素的关系和相互作用。 最常见的 Formatting
