# @ohos.file.picker (Picker)

> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.

The **picker** module encapsulates APIs of **PhotoViewPicker**, **DocumentViewPicker**, and **AudioViewPicker** to provide capabilities for selecting and saving images and videos, documents, and audio clips. The application can select the Picker as required. The APIs of this module must be called in a UIAbility. Otherwise, the **photoPicker** or **FilePicker** application cannot be started.

## Modules to Import

```ts
import  { picker } from '@kit.CoreFileKit';
```

## DocumentViewPicker

Provides APIs for selecting and saving documents in different formats. Before using the APIs of **DocumentViewPicker**, you need to create a **DocumentViewPicker** instance.

**System capability**: SystemCapability.FileManagement.UserFileService

### constructor<sup>12+</sup>

constructor(context: Context)

A constructor used to create a **DocumentViewPicker** instance. This constructor is recommended. For details about how to obtain the context, see [getContext](../apis-arkui/js-apis-getContext.md).

**Atomic service API**: This API can be used in atomic services since API version 12.

**System capability**: SystemCapability.FileManagement.UserFileService

**Parameters**
| Name | Type   | Mandatory| Description                                                        |
| ------- | ------- | ---- | ------------------------------------------------------------ |
| context | Context| Yes  | Application context (only **UIAbilityContext** is supported). For details about the application context of the stage model, see [Context](../apis-ability-kit/js-apis-inner-application-context.md).|

**Example**

```ts
import { common } from '@kit.AbilityKit';
import  { picker } from '@kit.CoreFileKit';
@Entry
@Component
struct Index {
  @State message: string = 'hello World';

  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(()=>{
            let context = getContext (this) as common.Context; // Ensure that getContext (this) returns UIAbilityContext.
            let documentPicker = new picker.DocumentViewPicker(context);
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
```

### constructor<sup>12+</sup>

constructor()

A constructor used to create a **DocumentViewPicker** instance. This constructor is not recommended due to the potential risk of operation failure.

**Atomic service API**: This API can be used in atomic services since API version 12.

**System capability**: SystemCapability.FileManagement.UserFileService

**Example**

```ts
let documentPicker = new picker.DocumentViewPicker(); // Construction without parameter is not recommended. There is a possibility that the DocumentViewPicker instance fails to start.
```

### constructor<sup>13+</sup>

constructor(context: Context, window: window.Window)

A constructor used to create a **DocumentViewPicker** object in a window created by an application. In other scenarios, you are advised to use **constructor(context: Context)** to create a **DocumentViewPicker** object.

**Parameters**
| Name | Type   | Mandatory| Description                                                        |
| ------- | ------- | ---- | ------------------------------------------------------------ |
| context | Context| Yes  | Application context (only **UIAbilityContext** is supported). For details about the application context of the stage model, see [Context](../apis-ability-kit/js-apis-inner-application-context.md).|
| window  | [window.Window](../apis-arkui/js-apis-window.md#window)  | Yes  | Window instance created by the application.|

> **NOTE**
>
> Currently, only mobile phones are supported.

**System capability**: SystemCapability.FileManagement.UserFileService

**Example**

```ts
import { common } from '@kit.AbilityKit';
import { picker } from '@kit.CoreFileKit';
import { window } from '@kit.ArkUI';

            let windowClass: window.Window | undefined = undefined;
            windowClass = window.findWindow ('test'); // Ensure that the window has been created. Here, 'test' is the value of the name parameter when the window is created.
            let documentPicker = new picker.DocumentViewPicker(context, windowClass);
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
```

import { common } from '@kit.AbilityKit';
import  { picker } from '@kit.CoreFileKit';
@Entry
@Component
struct Index {
  @State message: string = 'hello World';

  build() {
    Row() {
