我正在构建一个离子应用程序,在其中添加了工具栏标题,它具有5个可导航的按钮。 但是,当我在浏览器设备上尝试代码时,水平滚动条对于工具栏工作正常,但在实际设备中,它将无法正常工作。有时会滚动,有时不会。 下面是相同的代码。
<ion-header>
<ion-navbar color="light">
<ion-title>Home</ion-title>
<ion-buttons end>
<button ion-button icon-only>
<ion-icon name="search"></ion-icon>
</button>
<button ion-button icon-only>
<ion-icon name="cart"></ion-icon>
</button>
</ion-buttons>
</ion-navbar>
<ion-toolbar color="light">
<ion-buttons>
<button ion-button clear>{{'All'|translate}}</button>
</ion-buttons>
<ion-buttons *ngFor="let facet of parentCategories">
<button ion-button [ngClass]=" {'active' : selectedFacet == facet}">{{facet}}
</button>
<button ion-button icon-only clear class="accordion" (tap)="getSubFacets(facet);accordion(event)" *ngIf="selectedFacet == facet"><ion-icon name="ios-arrow-down"></ion-icon></button>
</ion-buttons>
<div id="sub-category" class="sub-category">
<ion-buttons *ngFor="let subFacet of childCategories">
<button ion-button [ngClass]=" {'active' : selectedSubFacet == subFacet}" (tap)="getFilteredProducts('categoryFacet',subFacetMap.get(subFacet), selectedFacet, subFacet)">
{{subFacet}}</button>
</ion-buttons>
</div>
</ion-toolbar>
</ion-header>
css:
.toolbar-content {
overflow-x: auto;
white-space: nowrap;
overflow-y: hidden;
width: 100%;
height: 56px;
}

我遇到了同样的问题,我遵循了这个示例
CSS:
ion-toolbar.scrollable-segments {
ion-segment {
display: block;
overflow-x: scroll;
white-space: nowrap;
ion-segment-button.segment-button {
display: inline-block;
width: auto;
}
}
}
HTML:
<ion-toolbar no-border class="scrollable-segments">
<ion-segment [(ngModel)]="segment">
<ion-segment-button value="all">
All
</ion-segment-button>
<ion-segment-button value="test">
Recent
</ion-segment-button>
<ion-segment-button value="test2">
Recent
</ion-segment-button>
<ion-segment-button value="test3">
Recent
</ion-segment-button>
<ion-segment-button value="test4">
Recent
</ion-segment-button>
<ion-segment-button value="test5">
Recent
</ion-segment-button>
<ion-segment-button value="test6">
Recent
</ion-segment-button>
<ion-segment-button value="test7">
Recent
</ion-segment-button>
</ion-segment>
</ion-toolbar>
