HarmonyOS 鸿蒙Next：为什么长按文字出现的复制菜单在swiper滑走后依然残留

【关键字】

关闭自定义选择菜单 / closeSelectionMenu

【问题描述】

长按文字出现的复制菜单在swiper滑走后依然残留。

Demo如下：

@Entry
@Component
struct CopyPage {
@State message: string = ‘长按我，出现复制菜单，然后左右滑动，菜单没消失’;
@Builder demoBuilder(){
Text(this.message)
.fontSize(50)
.fontWeight(FontWeight.Bold)
.layoutWeight(1)
.copyOption(CopyOptions.LocalDevice)
}
build() {
Row() {
Column() {
Swiper() {
ForEach([1,1,1,1,1,1,1,1,1,1,1,1], () => {
this.demoBuilder()
})
}
.layoutWeight(1)
}
.width(‘100%’)
}
.height(‘100%’)
}
} 

【解决方案】

closeSelectionMenu方法可以关闭自定义选择菜单或系统默认选择菜单。

API参考：

https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/ts-basic-components-text-V5#closeselectionmenu

Demo：

@Component
struct demoBuilder{
@Prop message: string;
@Link @Watch(‘onChange’) currentIndex: number;
onChange(){
this.tController.closeSelectionMenu()
}
private tController: TextController = new TextController();
build(){
Text(this.message, {controller: this.tController})
.fontSize(50)
.fontWeight(FontWeight.Bold)
.layoutWeight(1)
.copyOption(CopyOptions.LocalDevice)
}
}
@Entry
@Component
struct CopyPage {
@State message: string = ‘长按我，出现复制菜单，然后左右滑动，菜单没消失’;
@State currentIndex:number = 0;
build() {
Row() {
Column() {
Swiper(this.swiperController) {
ForEach([1,1,1,1,1,1,1,1,1,1,1,1], (item:number, index:number) => {
demoBuilder({message: this.message, currentIndex: this.currentIndex});
})
}
.layoutWeight(1)
.onChange((index:number)=>{
this.currentIndex = index;
})
}
.width(‘100%’)
}
.height(‘100%’)
}
}
