MapBox Android版开发 4 国际化功能v11

前言

在前文MapBox地图样式v11中,使用StylelocalizeLabels方法本地化地图语言。但Mapbox Standard样式和Mapbox Standard Satellite样式仍显示英文。本文将介绍MapBox国际化功能的使用方法。

遇到的问题

在前文本地化样式时,使用了localizeLabels方法,源码如下:

fun MapboxStyleManager.localizeLabels(locale: Locale, layerIds: List<String>? = null) {
  if (styleURI == "mapbox://styles/mapbox/standard") {
    throw RuntimeException(
      "Mapbox Standard style does not support client-side runtime localization." +
        " Consider using Mapbox internationalization capability instead: https://www.mapbox.com/blog/maps-internationalization-34-languages"
    )
  }
  setMapLanguage(locale, this, layerIds)
}

通过源码可以看出,若尝试切换Mapbox Standard地图语言时,SDK会抛出异常,并给出提示:不支持客户端运行时本地化,考虑使用Mapbox 国际化功能……

Mapbox Standard style does not support client-side runtime localization.

Consider using Mapbox internationalization capability …

那么MapBox推荐的国际化功能是什么?又如何实现Mapbox Standard样式地图语言的切换?从异常给出的链接可以找到答案。

国际化功能

Dynamically Localize Your Maps with Our New Internationalization Capability(2022),摘取部分原文:

  • Mapbox Internationalization Makes Localizing Maps Easy.

  • No more building and maintaining hundreds of styles.

  • With a more finite number of styles, the map loads dynamically and more quickly based on the users device or browser.

  • Rendering is dynamic and fast based on preferences in the device or browser, so users do not need to manually select a language display on the map.

原文给出的方案(V10版)

// Create a settings service instance as PERSISTENT, the 
// language set will be persisted across the application lifecycle.
private val settingsService: SettingsServiceInterface by lazy {
    SettingsServiceFactory.getInstance(SettingsServiceStorageType.PERSISTENT)
}
val locale = context.getResources().getConfiguration().locale
// set language in bcp-47 tag
val language = locale.language().toLanguageTag();
settingsService.set(MapboxCommonSettings.LANGUAGE, Value(language))

// set worldview
val worldView = "US"
settingsService.set(MapboxCommonSettings.WORLDVIEW, Value(worldView))

migrate-to-v11

在V11版中SettingsServiceInterface没有定义,参考官网migrate-to-v11中的说明:

The interface SettingsServiceInterface has been removed in favor of class SettingsService. SettingsServiceFactory.getInstance(...) now returns the SettingsService class.

适用于V11版的代码

// Create a settings service instance as PERSISTENT,
// the language set will be persisted across the application lifecycle.
private val settingsService: SettingsService by lazy {
    SettingsServiceFactory.getInstance(SettingsServiceStorageType.PERSISTENT)
}
val locale = context.resources.configuration.locales[0]
// set language in bcp-47 tag
val language = locale.toLanguageTag()
settingsService.set(MapboxCommonSettings.LANGUAGE, Value(language))

// set worldview
val worldView = "CN"
settingsService.set(MapboxCommonSettings.WORLDVIEW, Value(worldView))
// worldview: CN (China), IN (India), JP (Japan), US (United States)

示例

MapStyle类

修改Style的本地化示例代码

package com.example.mapdemo

import android.content.Context
import com.mapbox.bindgen.Value
import com.mapbox.common.MapboxCommonSettings
import com.mapbox.common.SettingsService
import com.mapbox.common.SettingsServiceFactory
import com.mapbox.common.SettingsServiceStorageType
import com.mapbox.maps.MapboxMap
import com.mapbox.maps.Style
import com.mapbox.maps.extension.localization.localizeLabels
import java.util.Locale

class MapStyle(map: MapboxMap) {
    private var map = map

    // Create a settings service instance as PERSISTENT,
    // the language set will be persisted across the application lifecycle.
    private val settingsService: SettingsService by lazy {
        SettingsServiceFactory.getInstance(SettingsServiceStorageType.PERSISTENT)
    }

    fun changeStyle(context: Context, style: String) {
        map.loadStyle(style) {
            if (style != Style.STANDARD && style != Style.STANDARD_SATELLITE) {
                it.localizeLabels(Locale.CHINESE)
            } else {
                val locale = context.resources.configuration.locales[0]
                // set language in bcp-47 tag
                val language = locale.toLanguageTag()
                settingsService.set(MapboxCommonSettings.LANGUAGE, Value(language))

                val worldView = "CN"
                settingsService.set(MapboxCommonSettings.WORLDVIEW, Value(worldView))
            }
        }
    }
}
