主题色

  1. 创建自定义主题色
//EntryAbility.ets
class myTheme implements CustomTheme{
  colors?: CustomColors

  constructor(color: CustomColors) {
    this.colors = color
  }
}
onWindowStageCreate(windowStage: window.WindowStage): void {
    // Main window is created, set main page for this ability
    hilog.info(0x0000, 'testTag', '%{public}s', 'Ability onWindowStageCreate');
    const theme = new myTheme()
    ThemeControl.setDefaultTheme(theme)
    //····
}
  1. 调用
//Index.ets
onWillApplyTheme(theme: Theme): void {
    this.fontColor = theme.colors.fontPrimary
}
Text("Hello World")
    .fontColor(this.fontColor)
