如何在 nativescript 中更改侧边抽屉的位置/位置

Question

我正在学习nativescript。我想改变从右侧打开的应用程序（现在它是从左侧打开）中侧抽屉的方向。我该怎么做？

这是我的代码：

app.component.html：

<RadSideDrawer tkExampleTitle tkToggleNavButton>
    <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>
        <Button text="Close Drawer" (tap)="onCloseDrawerTap()"></Button>
    </StackLayout>
    <StackLayout tkMainContent>
        <Label [text]="mainContentText" textWrap="true" class="drawerContentText"></Label>
        <Button text="OPEN DRAWER" (tap)="openDrawer()" class="drawerContentButton"></Button>
    </StackLayout>
</RadSideDrawer>

app.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-pro/sidedrawer/angular";
import { RadSideDrawer } from 'nativescript-telerik-ui-pro/sidedrawer';


@Component({
    moduleId: module.id,
    selector: "tk-sidedrawer-getting-started",
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.css']
})
export class AppComponent 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();
    }

}

app.module.ts:

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

import { AppComponent } from "./app.component";

@NgModule({
  declarations: [AppComponent],
  bootstrap: [AppComponent],
  imports: [NativeScriptModule, NativeScriptUISideDrawerModule ],
  schemas: [NO_ERRORS_SCHEMA],
})
export class AppModule {}

Answer 1

nativescript-telerik0ui 插件中的 RadSideDrawer 支持通过其 drawerLocation 属性更改其位置/位置。该属性可以设置为：

• 顶部
• 底部
• 左
• 对

您可以参考文档here 或sdk Angular 示例here 中的更多信息。

Answer 2

import { RadSideDrawerComponent, SideDrawerType } from "nativescript-ui-sidedrawer/angular";
import { SideDrawerLocation } from 'nativescript-ui-sidedrawer';

private currentLocation: SideDrawerLocation;
      onOpenDrawerTap() {
            this.drawerComponent.sideDrawer.drawerLocation = SideDrawerLocation.Top; //change location here Top, Right, Left, Bottom
            this.drawerComponent.sideDrawer.showDrawer();
        }
