Question

我正在尝试使用angular开发nativescript中的应用程序我想使用telerik-ui的侧抽屉像过滤面板一样，我将在主要内容文本区域中显示一些数据。问题是我启动代码时没有错误，除了没有sideDrawer的事实所有。我不知道如何调试它我目前正在尝试使用此示例对我的应用程序进行一些修改（仅文件名称）：
http://docs.telerik.com/devtools/nativescript-ui/Controls/Angular/SideDrawer/getting-started

filter.component.html：

<RadSideDrawer showOverNavigation="true" tkExampleTitle tkToggleNavButton class="page">
    <StackLayout tkDrawerContent class="sideStackLayout">
        <StackLayout class="sideTitleStackLayout">
            <Label text="Navigation Menu"></Label>
        </StackLayout>
        <StackLayout class="sideStackLayout">
            <Label text="Primary" class="sideLabel sideLightGrayLabel"></Label>
            <Label text="Social" class="sideLabel"></Label>
            <Label text="Promotions" class="sideLabel"></Label>
            <Label text="Labels" class="sideLabel sideLightGrayLabel"></Label>
            <Label text="Important" class="sideLabel"></Label>
            <Label text="Starred" class="sideLabel"></Label>
            <Label text="Sent Mail" class="sideLabel"></Label>
            <Label text="Drafts" class="sideLabel"></Label>
        </StackLayout>
        <Label text="Close Drawer" color="lightgray" padding="10" style="horizontal-align: center" (tap)="onCloseDrawerTap()"></Label>
    </StackLayout>
    <StackLayout tkMainContent>
        <Label [text]="mainContentText" textWrap="true" class="drawerContentText"></Label>
        <Button text="OPEN DRAWER" (tap)="openDrawer()" class="drawerContentButton"></Button>
    </StackLayout>
</RadSideDrawer>

filter.component.ts：

import { Component, ViewChild, OnInit, AfterViewInit, ChangeDetectorRef } from "@angular/core";
import { Page } from "ui/page";
import { ActionItem } from "ui/action-bar";
import { Observable } from "data/observable";
import { RadSideDrawerComponent, SideDrawerType } from "nativescript-telerik-ui/sidedrawer/angular";

    templateUrl: 'filter.component.html',
    styleUrls: ['filter.component.css']
})
export class SideDrawerGettingStartedComponent implements AfterViewInit, OnInit {
    private _mainContentText: string;

    constructor(private _changeDetectionRef: ChangeDetectorRef) {
    }

    @ViewChild(RadSideDrawerComponent) public drawerComponent: RadSideDrawerComponent;

    private drawer: RadSideDrawer;

    ngAfterViewInit() {
        this.drawer = this.drawerComponent.sideDrawer;
        this._changeDetectionRef.detectChanges();
    }

    ngOnInit() {
        this.mainContentText = "SideDrawer for NativeScript can be easily setup in the HTML definition of your page by defining tkDrawerContent and tkMainContent. The component has a default transition and position and also exposes notifications related to changes in its state. Swipe from left to open side drawer.";
    }

    get mainContentText() {
        return this._mainContentText;
    }

    set mainContentText(value: string) {
        this._mainContentText = value;
    }

    public openDrawer() {
        this.drawer.showDrawer();
    }

    public onCloseDrawerTap() {
       this.drawer.closeDrawer();
    }
}

filter.module.ts：

import { NgModule, NO_ERRORS_SCHEMA } from "@angular/core";
import { NativeScriptModule } from "nativescript-angular/nativescript.module";
import { NativeScriptUISideDrawerModule } from "nativescript-telerik-ui/sidedrawer/angular";


import { FilterRoutingModule } from "./filter.routing";
import { SideDrawerGettingStartedComponent } from "./filter.component";

@NgModule({
    imports: [
        NativeScriptModule,
        FilterRoutingModule,
        NativeScriptUISideDrawerModule
    ],
    declarations: [
        SideDrawerGettingStartedComponent
    ],
    schemas: [
        NO_ERRORS_SCHEMA
    ]
})
export class FilterModule { }

filter.routing.ts：

    import { NgModule } from "@angular/core";
    import { Routes } from "@angular/router";
    import { NativeScriptRouterModule } from "nativescript-angular/router";

    import { SideDrawerGettingStartedComponent } from "./filter.component";

    const routes: Routes = [
        { path: "filter", component: SideDrawerGettingStartedComponent }
    ];

    @NgModule({
        imports: [NativeScriptRouterModule.forChild(routes)],
        exports: [NativeScriptRouterModule]
    })
    export class FilterRoutingModule { }

filter.component.css：

 button {
    font-size: 15;
    horizontal-align: center;
}

.mainContentText {
    font-size: 13;
    padding: 10;
}

.mainContentButton {
    margin: 10;
    horizontal-align: left;
}

.drawerContentButton {
    color: yellowgreen;
}

.sideStackLayout {
    background-color: gray;
}

.sideTitleStackLayout {
    height: 56;
    text-align: center;
    vertical-align: center;
}

.sideLabel {
    padding: 10;
}

.sideLightGrayLabel {
    background-color: lightgray;
}

当我转到此过滤页面时，侧抽屉根本不显示。我的应用程序的结构与此类似：https://github.com/NativeScript/sample-Groceries

任何帮助都将不胜感激。

Answer 1

你有任何遗嘱吗？你确定你的Button标签有效吗？否则我得到了这个在我的项目上工作：我给了RadSideDrawer一个ID

<RadSideDrawer #drawer showOverNavigation="true" tkExampleTitle tkToggleNavButton class="page">

并像这样使用@ViewChild：

@ViewChild('drawer') public drawerComponent: RadSideDrawerComponent;

如果您有解决方案，请告诉我。

Answer 2

我设法通过在package.json文件中添加一些依赖项来解决我的问题为此，我创建了一个新的空白生成项目并安装了RadSideDrawer，我比较了我所拥有和升级的依赖项并添加了一些（例如我的依赖项列表中没有@ angular / animations）

nativescript angular sidedrawer没有出现错误
