Retrieve strings from a resource file

Code sample: Retrieving strings from a resource file

Example: CountryInfo.java (with localization support)

/**

* CountryInfo.java

package com.rim.samples.docs.countryinfo;

import net.rim.device.api.ui.*;

Task Steps

Retrieve the resource bundle. When the BlackBerry Integrated Development Environment builds your project, it creates an

interface for each .rrh resource file.

1. Import the interfaces that the BlackBerry IDE creates.

import com.rim.samples.docs.resource.CountryInfoResource;

2. Create a ResourceBundle object to contain the localized resources, such as strings, for an

application.

private static ResourceBundle _resources =

ResourceBundle.getBundle(CountryInfoResource.BUNDLE_ID,

CountryInfoResource.BUNDLE_NAME);

3. To retrieve the appropriate bundle family, invoke getBundle().

Create menu items using resources. >Use the MenuItem constructor that accepts a resource bundle and a resource instead of a

String for the name of the menu item.

private MenuItem _viewItem = new MenuItem(_resources, MENUITEM_VIEW,

110, 10) {

public void run() {

select = choiceField.getSelectedIndex();

_infoScreen = new InfoScreen();

UiApplication.getUiApplication().pushScreen(_infoScreen);

}

Replace text strings with the appropriate

resources.

1. For each field that appears on the main screen, replace the text string with the appropriate

resource.

2. Invoke getString() or getStringArray() to retrieve the string for the appropriate

language.

LabelField title = new

LabelField(_resources.getString(APPLICATION_TITLE),

LabelField.ELLIPSIS | LabelField.USE_ALL_WIDTH);

add(new RichTextField(_resources.getString(FIELD_TITLE)));

String choices[] = _resources.getStringArray(FIELD_COUNTRIES);

choiceField = new ObjectChoiceField(_resources.getString(FIELD_CHOICE),

choices);
