HTML

<div ng-controller="AppCtrl" ng-cloak="" class="tooltipdemoBasicUsage" ng-app="MyApp">
  <md-content layout-padding="">
    <md-button class="md-fab md-fab-top-right right" aria-label="Photos">
      <md-icon md-svg-src="img/icons/ic_photo_24px.svg" style="width: 24px; height: 24px;"></md-icon>
      <md-tooltip>
        List1<br>
        List2<br>

CSS:

  box-shadow: none;
  border: none;
  transform: none;
  -webkit-transform: none; }
.tooltipdemoBasicUsage .left {
  top: 70px !important;
  left: 56px !important; }
.tooltipdemoBasicUsage .right {
  top: 70px !important;
  right: 56px !important; }

JS

推荐答案

添加这种CSS似乎可以解决您的问题(对于<br> s):

Adding this CSS seems to work in your case (with the <br>s):

md-tooltip .md-content {
    height: auto;
}

我不确定为什么Angular-Material将高度硬编码为22px.您需要检查此更改是否破坏了其他工具提示.

I'm not sure why Angular-Material hard-coded the height to 22px. You'll need to check whether this change breaks other tooltips.

或者您可以仅通过给它一个类，例如将其专门应用于此用例. tt-multiline，因此您可以在CSS中定位它:

Or you can apply it specifically to this use case only by giving it a class, e.g. tt-multiline, so you can target it in CSS:

md-tooltip.tt-multiline .md-content {
    height: auto;
}

---

从Angular-Material 1.1开始，某些类名称已更改为以下划线开头.

---

Starting from Angular-Material 1.1, some class names have changed to start with a underscore.

在这种情况下，请使用

md-tooltip ._md-content {
    height: auto;
}

以及针对特定班级

md-tooltip.tt-multiline ._md-content {
    height: auto;
}
