力的区域设置为Android风味resConfig [英] Force locale for Android flavor with resConfig
问题描述
我想用resConfig和resConfigs从Android编译系统。
I am trying to use the resConfig and resConfigs from the Android Build system.
- Android的工作室版本1.2.2
- 在摇篮内部版本1.2.3
- 在OSX 10.10.3
我有问题，这两个选项与我的项目，所以我开始与Android工作室的一个新的空白项目。我重视我的build.gradle，我只加了resConfigsEN，FR在
I was having problem with these 2 options with my project so I started a new blank project with android studio. I attached my build.gradle where I only added resConfigs "en", "fr" under
android {
defaultConfig {
...
resConfigs "en", "fr"
...
}
}
和定义2基本形式
productFlavors {
fr {
resConfig "fr"
}
en {
resConfig "en"
}
}
然后，我创建了一个2的strings.xml文件和翻译参考hello world默认标签
I then created a 2 strings.xml files and translated the hello_world default label
/src/main/res/values/strings.xml（默认）
/src/main/res/values-en/strings.xml
/src/main/res/values-fr/strings.xml
/src/main/res/values/strings.xml (default)
/src/main/res/values-en/strings.xml
/src/main/res/values-fr/strings.xml
有了这个，我希望看到在所有MyApplication /应用/建立/只3个值的文件夹中间体/ RES /恩，因为我在resConfigs定义为只使用连接和FR和过滤别的/调试
With this, I would expect to see only 3 values folders in MyApplication/app/builds/intermediates/res/en/debug since I defined in the resConfigs to only use "en" and "fr" and filter anything else
/价值/
/值恩/
/值-FR /
/values/
/values-en/
/values-fr/
虽然，所有的语言值的文件夹仍然存在这样resConfigs没有任何过滤明显。
Although, all languages values folder are still in there so the resConfigs is not filtering anything apparently.
我也希望看到从标签参考hello world值恩运行enDebug味道变的时候，因为我指定的味道恩会用resConfig恩虽然当我运行测试软件，我看到/标签值-FR /strings.xml而不是/values-en/strings.xml因为在平板电脑上的语言设置为法语加拿大
I would also expect to see the label hello_world from values-en when running enDebug flavor variant since I specified that the flavor en would use resConfig "en" although when I run the test app I see the label from /values-fr/strings.xml instead of /values-en/strings.xml since the language on the tablet is configured as French Canada
我误解背后resConfig的目的是什么？如果是这样，我怎么强制的味道只在唯一的语言运行，不依赖于操作系统区域设置？因为我用他们在真正的应用程序，我想配置这个解决方案必须与flavorDimensions兼容了。
Am I misunderstanding the purpose behind resConfig? If so, how am I supposed to force a flavor to only run in only language and not be dependant on the OS locale setting? This solution must be compatible with flavorDimensions too since I use them in the real app I'm trying to configure.
注意：我也提出一个错误，因为我觉得真的有这个resConfig行为的 HTTPS：//$c$c.google.com/p/android/issues/detail ID = 180694
NOTE: I also filed a bug since I think there really is a problem with this resConfig behavior https://code.google.com/p/android/issues/detail?id=180694

推荐答案
好了，几个小时后，这里的解决我的问题，对于那些结束了同样的问题。
Well, after many hours, here's the solution to my problem for those ending up with the same problem.
原来，resConfig不是我所虽然。正确的，只有这样，我发现给力的语言环境特定的味道是这样的：
Turns out that resConfig is not for what I though. The proper and only way I found to force the locale for a specific flavor is like this:
首先，确保你所有的活动，扩展了其将负责强制语言环境的共同活动。 （我要创建2，因为我有一些活动延长FragmentActivity以及一些延伸的活动，我也真的不喜欢在活动构造这样做，但因为我有打电话给applyOverrideConfiguration之前的任何呼叫在getResources做，我需要活动的ONSTART 的），然后调用它。
First, make sure all your activities extends a common activity which will be responsible to force the locale. (I had to create 2 since I have some activities extending FragmentActivity and some extending Activity. I also don't really like doing so in the Activities constructor but since I have to call applyOverrideConfiguration before any call is done on getResources, I need to call it before the activity's onStart).
public class LocaleMainActivity extends Activity {
public LocaleMainActivity() {
ActivityUtils.forceLocale(this);
}
}
public class LocaleMainFragmentActivity extends FragmentActivity {
public LocaleMainFragmentActivity() {
ActivityUtils.forceLocale(this);
}
}
//Method from ActivityUtils
public static void forceLocale(ContextThemeWrapper contextThemeWrapper) {
Configuration configuration = new Configuration();
Locale defaultLocale = new Locale(BuildConfig.LOCALE);
configuration.locale = defaultLocale;
contextThemeWrapper.applyOverrideConfiguration(configuration);
}
接下来，你需要确定你的build.gradle口味的区域
Next, you need to define the locale in your build.gradle flavors
productFlavors {
myFrenchFlavor {
buildConfigField "String", "LOCALE", "\"fr\""
}
myEnglishFlavor {
buildConfigField "String", "LOCALE", "\"en\""
}
}
我测试的API 19+的解决方案。当您更改语言，而在应用程序中也起作用。
I tested the solution on API 19+. Works when you change language while in the app too.
替代的解决方案（不会对Android的M +合作<一href="https://$c$c.google.com/p/android-developer-$p$pview/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Owner%20Summary%20Stars&groupby=&sort=&id=2070"相对=nofollow>看到Android的bug报告 的）
该解决方案是在StackOverflow的广泛小号preaded但我面对一堵墙，而执行这项在Android中号所以请记住这一点。
Alternate solution (won't work on Android M+ see android bug report)
This solution is wide spreaded on stackOverflow but I faced a wall while implementing this on Android M so keep this in mind.
在OnCreate（）你AndroidApplication，你可以调用updateConfiguration与区域集。
In the onCreate() of your AndroidApplication you can call updateConfiguration with the locale set.
Locale myLocale = new Locale(BuildConfig.LOCALE);
Resources res = getResources();
Configuration conf = res.getConfiguration();
conf.locale = myLocale;
res.updateConfiguration(conf, res.getDisplayMetrics());
您还需要重置，如果你定义onConfigurationChanged（）
You will also need to reset it if you defined onConfigurationChanged()
@Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
Configuration config = new Configuration(newConfig);
config.locale = new Locale(BuildConfig.LOCALE);
getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
}
编辑：请注意，这applyOverrideConfiguration目前有一个副作用，这是在这里解释<一个href="http://stackoverflow.com/questions/32050784/chromium-webview-does-not-seems-to-work-with-android-applyoverrideconfiguration">Chromium web视图似乎并不与Android applyOverrideConfiguration 的工作。铬团队目前正在努力就可以了！
Be aware that this applyOverrideConfiguration currently has a side effect which is explained here Chromium webview does not seems to work with Android applyOverrideConfiguration. The Chromium team are currently working on it!
