#鸿蒙学习大百科#如何在申请ohos.permission.READ_AUDIO权限时，使用AudioViewPicker来做替代方案？

//1.导入选择器模块和文件管理模块。
import picker from '@ohos.file.picker';
import fs from '@ohos.file.fs';
import { BusinessError } from '@ohos.base';
//2.创建音频类型文件选择选项实例。
//目前AudioSelectOptions不支持参数配置，默认可以选择所有类型的用户文件。
const audioSelectOptions = new picker.AudioSelectOptions();

@Entry
@Component
struct Index {
  build() {
    Row() {
      Column() {
        Text("Hello")
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            // 3.创建音频选择器实例。调用select()接口拉起FilePicker应用界面进行文件选择。
            const audioViewPicker = new picker.AudioViewPicker();
            audioViewPicker.select(audioSelectOptions).then((audioSelectResult: Array<string>) => {
              let uri: string = '';
              uri = audioSelectResult[0];
              console.info('audioViewPicker.select to file succeed and uri is:' + uri);
            }).catch((err: BusinessError) => {
              console.error(`Invoke audioViewPicker.select failed, code is ${err.code}, message is ${err.message}`);
            })
          })
      }
      .width('100%')
    }
    .height('100%')
  }
