在TextInput中设置了customKeyboard，在自定义键盘中有【中文】按钮，点击后预期效果是切换到系统的中文输入法，请问这个要怎么实现呢？

参考这个示例：

@Entry  
@Component  
struct KeyboadPage2 {  
  controller: TextInputController = new TextInputController()  
  @State inputValue: string = ""  
  @State show: boolean = false  
  @State InputBGColor: string = '#90EE90'  
  // 自定义键盘组件  
  @Builder  
  CustomKeyboardBuilder() {  
    Column() { //  
      Button('x')  
        .onClick(() => {  
          // 关闭自定义键盘  
          this.controller.stopEditing()  
          this.show = !this.show  
        })  
      Grid() {  
        ForEach([1, 2, 3, 4, 5, 6, 7, 8, 9, '*', 0, '#'], (item: number | string) => {  
          GridItem() {  
            Button(item + "").width(110).onClick(() => {  
              this.inputValue += item  
            })  
          }  
        })  
      }.maxCount(3).columnsGap(10).rowsGap(10).padding(5)  
    }.backgroundColor(Color.Gray)  
  }  
  build() {  
    Column({ space: 10 }) {  
      TextInput({  
        controller: this.controller,  
        text: this.inputValue  
      })  
        .id('111')  
        .backgroundColor(this.InputBGColor)// 绑定自定义键盘  
        .customKeyboard(this.show ? this.CustomKeyboardBuilder() : undefined)  
        .margin(10)  
        .border({ width: 1 })  
        .height('48vp')  
        .onChange((val)=>{  
          this.inputValue = val  
        })  
        .onFocus(() => {  
          this.InputBGColor = '#FF0000'  
        })  
        .onBlur(() => {  
          this.InputBGColor = '#90EE90'  
        })  
      Button('组件失焦').onClick(() => {  
        setTimeout(() => {  
          focusControl.requestFocus('333')  
        }, 0)  
      }).id('333')  
      Button('组件获焦/切换').onClick(() => {  
        setTimeout(() => {  
          focusControl.requestFocus('111')  
        }, 200)  
        focusControl.requestFocus('333')  
        this.show = !this.show  
      })  
    }  
  }  
}
