Obscuring

When needed, you can obscure content of a component.

NOTE

The APIs of this module are supported since API version 10. Updates will be marked with a superscript to indicate their earliest API version.

Attributes

Name	Type	Description
obscured	Array<ObscuredReasons>	How the component content is obscured. Default value: [] This API is supported in ArkTS widgets. This API only works for the <Image> and <Text> components. NOTE To obscure an image when it is being loaded, you must set the width and height of the <Image> component.

Example

// xxx.ets
@Entry
@Component
struct ObscuredExample {
  build() {
    Row() {
      Column() {
        Text('Text not set obscured attribute').fontSize(10).fontColor(Color.Black)
        Text('This is an example for text obscured attribute.')
          .fontSize(30)
          .width('600px')
          .fontColor(Color.Black)
          .border({ width: 1 })
        Text('Image not set obscured attribute').fontSize(10).fontColor(Color.Black)
        Image($r('app.media.icon'))
          .width('200px')
          .height('200px')
        Text('Text set obscured attribute').fontSize(10).fontColor(Color.Black)
        Text('This is an example for text obscured attribute.')
          .fontSize(30)
          .width('600px')
          .fontColor(Color.Black)
          .border({ width: 1 })
          .obscured([ObscuredReasons.PLACEHOLDER])
        Text('Image set obscured attribute').fontSize(10).fontColor(Color.Black)
        Image($r('app.media.icon'))
          .width('200px')
          .height('200px')
          .obscured([ObscuredReasons.PLACEHOLDER])
      }
      .width('100%')
