HarmonyOS 鸿蒙Next documentViewPicker文件选择器调起后不进行选择直接关闭如何触发回调函数

不选择直接关闭的话会触发这个回调 

```javascript
try {
    let documentSelectOptions = new picker.DocumentSelectOptions();
    let documentPicker = new picker.DocumentViewPicker(context);
    documentPicker.select(documentSelectOptions, (err: BusinessError, documentSelectResult: Array<string>) => {
        if (err) {
            console.error('DocumentViewPicker.select failed with err: ' + JSON.stringify(err));
            return;
        }
        console.info('DocumentViewPicker.select successfully, documentSelectResult uri: ' + JSON.stringify(documentSelectResult));
    });
} catch (error) {
    let err: BusinessError = error as BusinessError;
    console.error('DocumentViewPicker failed with err: ' + JSON.stringify(err));
}

示例代码：

import { BusinessError } from '[@kit](/user/kit).BasicServicesKit';
import { common } from '[@kit](/user/kit).AbilityKit';
import { picker } from '[@kit](/user/kit).CoreFileKit';

async function example08(context: common.Context) { // 需确保 context 由 UIAbilityContext 转换而来

    try {
        let documentSelectOptions = new picker.DocumentSelectOptions();
        let documentPicker = new picker.DocumentViewPicker(context);
        documentPicker.select(documentSelectOptions, (err: BusinessError, documentSelectResult: Array<string>) => {
            if (err) {
                console.error('DocumentViewPicker.select failed with err: ' + JSON.stringify(err));
                return;
            }
            console.info('DocumentViewPicker.select successfully, documentSelectResult uri: ' + JSON.stringify(documentSelectResult));
        });
    } catch (error) {
        let err: BusinessError = error as BusinessError;
        console.error('DocumentViewPicker failed with err: ' + JSON.stringify(err));
    }
}
