最近有需求需要切换系统语言的功能,查阅api最终搞定,代码分享如下:
1.切换语言
public void updateLanguage(Locale locale) {
try {
Object objIActMag;
Class clzIActMag = Class.forName("android.app.IActivityManager");
Class clzActMagNative = Class
.forName("android.app.ActivityManagerNative");
//amn = ActivityManagerNative.getDefault();
Method mtdActMagNative$getDefault = clzActMagNative
.getDeclaredMethod("getDefault");
objIActMag = mtdActMagNative$getDefault.invoke(clzActMagNative);
// objIActMag = amn.getConfiguration();
Method mtdIActMag$getConfiguration = clzIActMag
.getDeclaredMethod("getConfiguration");
Configuration config = (Configuration) mtdIActMag$getConfiguration
.invoke(objIActMag);
// set the locale to the new value
config.locale = locale;
//持久化 config.userSetLocale = true;
Class clzConfig = Class
.forName("android.content.res.Configuration");
java.lang.reflect.Field userSetLocale = clzConfig
.getField("userSetLocale");
userSetLocale.set(config, true);
// 此处需要声明权限:android.permission.CHANGE_CONFIGURATION
// 会重新调用 onCreate();
Class[] clzParams = { Configuration.class};
// objIActMag.updateConfiguration(config);
Method mtdIActMag$updateConfiguration = clzIActMag
.getDeclaredMethod("updateConfiguration", clzParams);
mtdIActMag$updateConfiguration.invoke(objIActMag, config);
BackupManager.dataChanged("com.android.providers.settings");
} catch (Exception e) {
e.printStackTrace();
}
}
2.系统当前语言
public String getcurlanguage() {
Locale locale = mContext.getApplicationContext().getResources().getConfiguration().locale;
String language = locale.getLanguage();
if (language.equals("zh")) { //中文
return mContext.getResources().getString(R.string.language_chinese);
} else if (language.equals("en")) { //英文
return mContext.getResources().getString(R.string.language_english);
} else {
return mContext.getResources().getString(R.string.language_chinese);
}
}
这就是全部代码了 仅供参考
