问题描述
我正在尝试将“fa”设置为我的项目中的主要语言环境，将“en”设置为第二个语言环境。所以基本上我的主要 string.xml 文件是 "fa" 。支持 RTL 值为 "true" 和 Layout direction="locale"
应用程序不断向我显示从左到右的布局方向。
我的设备语言是美国英语，但我希望我的应用程序默认显示在“fa”中。
这是我的设置活动代码：

dialog.dismiss()
setNewLocale(codes[i])
}
dialog.listLanguage.apply {

}

}
}
switchNotification.setonCheckedchangelistener { _,isChecked ->

khorshidApp.changeAppTheme(isChecked)

}
Handler().postDelayed({ mIsSelectedByUser = true },1000)
}

if (mIsLanguageUpdated) {
setResult(Activity.RESULT_OK)
finish()
} else {

Log.e("lan",language)

getSharedPrefInstance().setValue(LANGUAGE,language)
