Imitation Hema - User Login Page (Static) (20)

Technical Stack
Appgallery Connect

Development Preparation In the previous section, we implemented the static display of the personal center page. Now that the project has progressed to this stage, it's time to add user-related functionality. Since our data will be user-specific in the later stages and not shared between different users, we need to add a user login entry to the application to implement user binding.

Functional Analysis The content of the user login page is relatively straightforward. First, we'll implement the static layout, which includes a logo, account/password input fields, a login button, and request status indicators. Later, we'll add business logic to enrich its functionality.

Code Implementation

typescript import promptAction from '@ohos.promptAction';

@Entry @Component struct LoginPage { @State userId: string = '';

aboutToAppear() {}

@State message: string = 'Login Page'; @State acc: string = ''; @State psw: string = ''; @State isShowProgress: boolean = true;

controller: TextInputController = new TextInputController();

login(): void { if (this.acc === '' && this.psw === '') { promptAction.showToast({ message: "Please enter your account and password" }); return; } else { this.isShowProgress = false; } }

@Builder imageButton(src: string) { Button({ type: ButtonType.Circle, stateEffect: true }) { Image(src) .height(20) .width(20); } .height(50) .width(50); }

build() { Row() { Column() { Image($r('app.media.logo')) .width(120) .height(120) .borderRadius(60);

Text("Login Interface") .width(80) .fontSize(14) .fontColor("#333333") .margin({ top: 40 }) .fontWeight(FontWeight.Medium);

TextInput({ text: "15290959515", placeholder: 'Enter your account' }) .backgroundColor("#f6f6f6") .placeholderColor("#ff999595") .fontColor("#333333") .maxLength(11) .type(InputType.Number) .onChange((value: string) => { this.acc = value; }) .margin(20);

TextInput({ text: "123456", placeholder: 'Enter your password' }) .backgroundColor("#f6f6f6") .placeholderColor("#ff999595") .fontColor("#333333") .type(InputType.Password) .onChange((value: string) => { this.psw = value; }) .margin(20);

Row() { Text('Register') .fontColor(Color.Blue) .fontSize(14) .margin(30);

Text('Forgot Password') .fontColor(Color.Blue) .fontSize(14) .margin(30); } .width('100%') .justifyContent(FlexAlign.SpaceBetween);

if (this.isShowProgress) { LoadingProgress() .width(60) .height(60) .backgroundColor(Color.Pink) .margin({ top: $r('app.float.login_progress_margin_top') }); }

Button('Login', { type: ButtonType.Capsule, stateEffect: false }) .onClick(() => { this.isShowProgress = true; this.login(); }) .fontColor(Color.White) .width('80%') .height(40) .margin(40) .backgroundColor(0xff0000);

Blank().margin(30); } .width('100%'); } .height('100%') .backgroundColor('#FFFFFF') .justifyContent(FlexAlign.Center); } }

After implementation, we can check the execution results. This completes the static layout of the login page.
