离子副标题栏重叠内容

Question

在带有标题和子标题的视图中,子标题内容与视图的内容重叠.

• 幻灯片菜单中的标题

    <ion-nav-buttons side="left">
      <button class="button button-icon button-clear ion-navicon" menu-toggle="left" ng-hide="$exposeAside.active"></button>
    </ion-nav-buttons>
  </ion-nav-bar>
  
  <ion-nav-view name="menuContent" animation="slide-left-right"></ion-nav-view>
  

• 视图中的子标题

  <ion-header-bar align-title="center" class="bar bar-subheader custom bar-energized" ng-if="datos.subTitulo"> <div class="buttons"> <a class="ion-chevron-left" href="#/app/ranking/ubicacion/{{datos.divAnt}}" ng-if="datos.divAnt"></a> </div> <h2 class="subtitle">{{datos.subTitulo}}</h2> <div class="buttons"> <a class="ion-chevron-right" href="#/app/ranking/ubicacion/{{datos.divSig}}" ng-if="datos.divSig"></a> </div> </ion-header-bar>

子标题中的Dvis按钮重叠内容,h2显示100%.这段代码中缺少什么东西？谢谢

[编辑]重新编写代码以满足我的需要:小于标题的子标题,角落中有两个链接和标题.

<ion-header-bar align-title="center" class="bar-subheader subheader_custom bar-energized">
    <div class="button button-clear"> 
        <a class="icon ion-ios-arrow-back blanco" href="#/app/ranking/ubicacion/{{datos.divAnt}}" ng-if="datos.divAnt"></a>
    </div>
    <div class="h2 title title_custom">{{datos.subTitulo}}</div>
    <div class="button button-clear"> 
        <a class="icon ion-ios-arrow-forward blanco" href="#/app/ranking/ubicacion/{{datos.divSig}}" ng-if="datos.divSig"></a>
    </div>
</ion-header-bar>

添加此css:

.has-subheader {
    top: 70px;
}

.bar-subheader.subheader_custom {
    display: block;
    height: 26px;
    top: 44px;
}
.title.title_custom {
    font-size: 16px;
    font-weight: 300;
    height: 20px;
    left: 0;
    line-height: 20px;
    margin: 2px 10px 2px 10px;
    min-width: 24px;
    overflow: hidden;
    position: absolute;
    right: 0;
    text-align: center;
    text-overflow: ellipsis;
    top: 0;
    white-space: nowrap;
    z-index: 0;
}

即使按钮也与子标题标题不一致.有任何想法吗？

确保内容视图知道需要通过添加CSS类为子标题留出空间has-subheader:

<ion-content class="has-header has-subheader">
</ion-content>
