We have our settings screen, but no settings.
У нас есть окно настроек, но нет самих настроек.
In the next several sections, you're going to be adding our two settings.
В нескольких следующих разделах вы добавите две настройки.
I'll walk you through how we add our first setting for location,
Я покажу, как добавить первую из них, для местоположения,
then you'll do the temperature setting on your own, so listen closely.
затем вы сами добавите настройку температуры, так что слушайте внимательно.
First, we design a Preference XML file.
Сначала мы напишем XML-файл для настроек.
The root element should be a PreferenceScreen.
Корневым элементом должен быть PreferenceScreen.
In this example, we have a CheckBoxPreference
В данном случае внутри расположены
and a ListPreference inside of it.
CheckBoxPreference и ListPreference.
In order to add the Preferences XML file to our app,
Чтобы добавить в приложение XML-файл настроек,
we first need to create an XML folder under the resources res directory.
нужно создать папку xml в директории с ресурсами res.
Right-click on the res folder, go to New / Android resource directory,
Нажмите правой кнопкой на папке res, затем на New → Android resource directory
and then type in xml as the name of the directory.
и введите xml в качестве названия папки.
For resource type you can use xml and then hit OK.
Выберите xml в списке Resource type и нажмите OK.
Inside this folder, we right-click to create a new XML Resource File.
Нажмите правой кнопкой внутри папки, чтобы создать новый XML-файл.
We call it pref_general,
Назовём его pref_general,
and the Root element is a PreferenceScreen as we saw on the developer's site.
корневым элементом будет PreferenceScreen, как мы видели на сайте для разработчиков.
And then our Preferences file is created.
Теперь файл настроек создан.
Then, add the location preference.
Добавьте настройку местоположения.
Since the wireframes showed an editable text field
Поскольку на схеме изображено поле для редактируемого текста,
to input user location as a string, we make this an EditTextPreference.
через которое пользователь вводит своё местоположение в виде строки, мы воспользуемся EditTextPreference.
If you want to learn more about all the possible XML attributes,
Если вы хотите узнать больше обо всех возможных XML-атрибутах,
you can Google for EditTextPreference.
погуглите EditTextPreference.
First, we specify a title for the preference,
Сначала мы укажем заголовок настройки,
which will be the label that's displayed to the user.
который будет показан пользователю.
Then, we specify a key.
Потом укажем ключ
And this key is actually the Key Value in SharedPreferences.
из пары ключ -- значение в SharedPreferences.
Going back to the code, we also add these attributes to describe the Edit Text field
Мы добавим эти атрибуты в код, чтобы описать поле EditText
in the pop up dialog that was shown in the wire frames.
во всплывающем окне разметки.
Going back to the code, we can also configure properties of the Edit Text field.
Мы настроим также свойства поля EditText.
We specify the input type to be text, and we cap it to a single line of text.
В качестве типа ввода мы укажем text и ограничим его до одной строки.
It's bad practice to hard code these strings here,
Было бы плохой идеей присваивать значения этим текстовым строкам внутри кода,
so we declare them as constants in the strings.xml file.
поэтому мы объявим их константами в файле strings.XML.
These are the strings we declared.
Вот строки, которые мы объявили.
This is the name of the label of the preference.
Это название ярлыка настройки, видимое пользователю.
It's user-visible, so we add a char limit for translation purposes.
Поэтому необходимо наложить ограничение на количество символов на случай переводов.
You also specify location, which is the name of the key in Shared Preferences.
Мы объявили и location -- название ключа в SharedPreferences.
We don't want to translate it because we always want to find the key
Переводить слово location не нужно,
based on this name.
потому что по этому названию мы будем находить ключ.
We also specify a constant for the default location.
Мы объявили константу местоположения по умолчанию.
We also don't translate this because we need to send it to the server API like this.
Её тоже нельзя переводить — она будет отсылаться к API сервера.
When you're done with these steps, check them off and continue.
Когда закончите, отметьте галочками эти шаги и продолжайте дальше.
