@ohos.resourceManager (Resource Management)

The resourceManager module provides APIs to obtain information about application resources based on the current configuration, including the language, region, screen direction, MCC/MNC, as well as device capability and density.

NOTE

The initial APIs of this module are supported since API version 6. Newly added APIs will be marked with a superscript to indicate their earliest API version.

Modules to Import

import resourceManager from '@ohos.resourceManager';

How to Use

Since API version 9, the stage model allows an application to obtain a ResourceManager object based on context and call its resource management APIs without first importing the required bundle. This approach, however, is not applicable to the FA model. For the FA model, you need to import the required bundle and then call the getResourceManager API to obtain a ResourceManager object. For details about how to reference context in the stage model, see Context in the Stage Model.

import UIAbility from '@ohos.app.ability.UIAbility';
import window from '@ohos.window';

export default class EntryAbility extends UIAbility {
  onWindowStageCreate(windowStage: window.WindowStage) {
    let context = this.context;
    let resourceManager = context.resourceManager;
  }
}

resourceManager.getResourceManager

getResourceManager(callback: AsyncCallback<ResourceManager>): void

Obtains the ResourceManager object of this application. This API uses an asynchronous callback to return the result.

System capability: SystemCapability.Global.ResourceManager

Model restriction: This API can be used only in the FA model.

Parameters

Name Type Mandatory Description
callback AsyncCallback<ResourceManager> Yes Callback used to return the result.

Example

  resourceManager.getResourceManager((error, mgr) => {
    if (error != null) {
      console.log("error is " + error);
      return;
    }
    mgr.getStringValue(0x1000000, (error, value) => {
      if (error != null) {
        console.log("error is " + error);
      } else {
        let str = value;
      }
    });
  });

NOTE
In the sample code, 0x1000000 indicates the resource ID, which can be found in the compiled ResourceTable.txt file.
