最终结果如下：

基本上,我们使用Ionic滑块组件来显示类别,但每张幻灯片最多显示3个类别.

视图：

在视图中我们只需要添加一个包含行的工具栏,其中包含3列：一列用于左箭头,另一列用于滑块,最后一列用于右箭头.另请注意,我们在ion-slides元素中设置了slidesPerView =“3”属性.

<ion-header>
    <ion-navbar color="primary">
        <button ion-button menuToggle>
            <ion-icon name="menu"></ion-icon>
        </button>
        <ion-title>App Name</ion-title>
    </ion-navbar>
    <ion-toolbar>
        <ion-row class="filters">
            <ion-col class="col-with-arrow" (click)="slidePrev()" no-padding col-1>
                <ion-icon *ngIf="showLeftButton" name="arrow-back"></ion-icon>
            </ion-col>
            <ion-col no-padding col-10>
                <ion-slides (ionSlideDidChange)="slideChanged()" slidesPerView="3">
                    <ion-slide (click)="filterData(category.id)" *ngFor="let category of categories">
                        <p [class.selected]="selectedCategory?.id === category.id">{{ category.name }}</p>
                    </ion-slide>
                </ion-slides>
            </ion-col>
            <ion-col class="col-with-arrow" (click)="slideNext()" no-padding col-1>
                <ion-icon *ngIf="showRightButton" name="arrow-forward"></ion-icon>
            </ion-col>
        </ion-row>

    </ion-toolbar>
</ion-header>

组件代码：

然后我们只需要处理选择任何类别时或当前幻灯片更改时要执行的操作：

// Angular
import { Component,Injector,ViewChild } from '@angular/core';

// Ionic
import { IonicPage,Slides } from 'ionic-angular';

// Models
import { CategoryModel } from './../../models/category.model';

@Component({ ... })
export class HomePage {
    @ViewChild(Slides) slides: Slides;

    public selectedCategory: CategoryModel;
    public categories: Array<CategoryModel>;
    public showLeftButton: boolean;
    public showRightButton: boolean;

    constructor(public injector: Injector) { ... }

    // ...

    private initializeCategories(): void {

        // Select it by defaut
        this.selectedCategory = this.categories[0];

        // Check which arrows should be shown
        this.showLeftButton = false;
        this.showRightButton = this.categories.length > 3;
    }

    public filterData(categoryId: number): void {
        // Handle what to do when a category is selected
    }

    // Method executed when the slides are changed
    public slideChanged(): void {
        let currentIndex = this.slides.getActiveIndex();
        this.showLeftButton = currentIndex !== 0;
        this.showRightButton = currentIndex !== Math.ceil(this.slides.length() / 3);
    }

    // Method that shows the next slide
    public slideNext(): void {
        this.slides.slideNext();
    }

    // Method that shows the prevIoUs slide
    public slidePrev(): void {
        this.slides.slidePrev();
    }
}

样式：

.filters {

        ion-col {
            text-align: center;
            font-size: 1.6rem;
            line-height: 1.6rem;

            ion-icon {
                color: #ccc;
            }

            &.col-with-arrow {
                display: flex;
                justify-content: center;
                align-items: center;
            }
        }

        p {
            color: #fff;
            margin: 0;
            font-size: 1.6rem;
            line-height: 1.6rem;
        }

        .selected {
            font-weight: 700;
        }
    }
