可以在EntryAbility中的onWindowStageCreate中用display来获取屏幕的宽高,并将其通过AppStorage进行存储,然后在需要使用的页面处使用,以下是简单示例:// EntryAbility.ets import display from '@ohos.display'; // 屏幕属性 let screenHeight: number = 0; // 保存屏幕高度(px) let screenWidth: number = 0; // 保存屏幕宽度(px) export default class EntryAbility extends UIAbility { onCreate(want: Want, launchParam: AbilityConstant.LaunchParam): void { hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onCreate'); } onWindowStageCreate(windowStage: window.WindowStage): void { // 通过屏幕属性获取屏幕宽高 display.getAllDisplays((err,data) => { screenHeight = data[0].height; screenWidth = data[0].width; // 使用AppStorage存储获取的屏幕宽高 AppStorage.setOrCreate('globalScreenHeight', screenHeight); AppStorage.setOrCreate('globalScreenWidth', screenWidth); hilog.info(0x0000, 'testTag', `${screenHeight} --- ${screenWidth}`, 'Ability onWindowStageCreate') }) } onForeground(): void { // Ability has brought to foreground hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onForeground'); } onBackground(): void { // Ability has back to background hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onBackground'); } } // Index.ets // 在页面中使用 @Entry @Component struct Index { @State screenHeight: number | undefined = AppStorage.get('globalScreenHeight'); build() { Column() { Text('屏幕高度:' + this.screenHeight) } } }屏幕属性请参考: https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-display-V5AppStorage请参考:https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/arkts-appstorage-V5
