Mia好纠结如何获取文本框里的文字宽度
云端小仙女解决措施
使用measureText计算指定文本单行布局的宽度。
代码示例
import { MeasureText } from '@kit.ArkUI';
@Entry
@Component
struct Index {
@State message: string = 'Hello World'
@State textWidth: number = MeasureText.measureText({
textContent: "Hello word",
fontSize: '50px'
})
build() {
Row() {
Column() {
Text("The width of 'Hello World': " + this.textWidth)
}
.width('100%')
}
.height('100%')
}
}
