HarmonyOS 鸿蒙Next TextInput自动获取焦点问题

或者可以给TextInput添加enableKeyboardOnFocus(false)属性，禁用除点击以外的获焦

点击的时候可以重新设置获焦，属性重新设置为true

也可使用requestFocus 方式，下面是相关demo:

import prompt from '@ohos.prompt'
@Entry
@Component
struct Index {
@State message: string = ‘Hello World’;
@State isboole:boolean=true;
build() {
Row() {
Column() {
Text(this.message)
.id(‘1sa’)
.fontSize(50)
.fontWeight(FontWeight.Bold)
    Button(<span class="hljs-string">'我会获取焦点'</span>)
      .key(<span class="hljs-string">'BBB'</span>)

    TextInput({ placeholder: <span class="hljs-string">'AAAAA'</span> })
      .id(<span class="hljs-string">'AAAA1'</span>)
      .type(InputType.Normal)

    Button(<span class="hljs-string">'点击焦点转移'</span>)
      .onClick(()=&gt;{
        <span class="hljs-keyword">let</span> res=focusControl.requestFocus(<span class="hljs-string">'BBB'</span>)
        <span class="hljs-keyword">if</span> (res) {
          prompt.showToast({message: <span class="hljs-string">'Request success'</span>})
        } <span class="hljs-keyword">else</span> {
          prompt.showToast({message: <span class="hljs-string">'Request failed'</span>})
        }
      })

    Button(<span class="hljs-string">'点击获取焦点'</span>)
      .onClick(()=&gt;{
        <span class="hljs-keyword">this</span>.isboole=<span class="hljs-literal">true</span>
        sendEventByKey(<span class="hljs-string">"AAAA1"</span>, <span class="hljs-number">10</span>, <span class="hljs-string">""</span>) <span class="hljs-comment">// 向id为"longClick"的组件发送点击事件</span>
      })
  }
  .width(<span class="hljs-string">'100%'</span>)
}
.height(<span class="hljs-string">'100%'</span>)
}
}

使用 requestFocus 方法转移焦点

以下是参考demo:

import prompt from ‘@ohos.prompt’
import promptAction from ‘@ohos.promptAction’

let customDialogId: number = 0
@Builder
function customDialogBuilder() {
Column() {
Text(‘Custom dialog Message’).fontSize(20)
Row() {
Button(“确认”).onClick(() => {
promptAction.closeCustomDialog(customDialogId)
})
  Blank()
    .width(<span class="hljs-number">50</span>)

  Button(<span class="hljs-string">"取消"</span>).onClick(() =&gt; {
    promptAction.closeCustomDialog(customDialogId)
    <span class="hljs-keyword">let</span> res=focusControl.requestFocus(<span class="hljs-string">'BBB'</span>)
    <span class="hljs-keyword">if</span> (res) {
      prompt.showToast({message: <span class="hljs-string">'Request success'</span>})
    } <span class="hljs-keyword">else</span> {
      prompt.showToast({message: <span class="hljs-string">'Request failed'</span>})
    }
  })
}
.padding(<span class="hljs-number">45</span>)
}
.height(200).padding(35)
}
@Entry
@Component
struct Index {
@State message: string = ‘Hello World’;
@State isboole:boolean = true;
build() {
Row() {
Column() {
Text(this.message)
.id(‘1sa’)
.fontSize(50)
.fontWeight(FontWeight.Bold)
    Button(<span class="hljs-string">'我会获取焦点'</span>)
      .key(<span class="hljs-string">'BBB'</span>)

    TextInput({ placeholder: <span class="hljs-string">'AAAAA'</span> })
      .id(<span class="hljs-string">'AAAA1'</span>)
      .type(InputType.Normal)

    TextInput({ placeholder: <span class="hljs-string">'CCCCC'</span> })
      .id(<span class="hljs-string">'CCCCC'</span>)
      .type(InputType.Normal)

    Button(<span class="hljs-string">'点击出现弹窗'</span>)
      .onClick(()=&gt;{
        <span class="hljs-comment">// let res=focusControl.requestFocus('BBB')</span>
        <span class="hljs-comment">// if (res) {</span>
        <span class="hljs-comment">//  prompt.showToast({message: 'Request success'})</span>
        <span class="hljs-comment">// } else {</span>
        <span class="hljs-comment">//  prompt.showToast({message: 'Request failed'})</span>
        <span class="hljs-comment">// }</span>

        promptAction.openCustomDialog({
          builder: customDialogBuilder.bind(<span class="hljs-keyword">this</span>)
        }).then((dialogId: number) =&gt; {
          customDialogId = dialogId
        })
      })

    Button(<span class="hljs-string">'点击获取焦点'</span>)
      .onClick(()=&gt;{
        <span class="hljs-keyword">this</span>.isboole=<span class="hljs-literal">true</span>
        sendEventByKey(<span class="hljs-string">"AAAA1"</span>, <span class="hljs-number">10</span>, <span class="hljs-string">""</span>) <span class="hljs-comment">// 向id为"longClick"的组件发送点击事件</span>
      })
  }
  .width(<span class="hljs-string">'100%'</span>)

}
.height(<span class="hljs-string">'100%'</span>)
}
}
