Currently this is our forecast list. It looks okay, but it would be nice if we could show the degree symbol for these temperature values.

現在の予報リストをさらによくするため温度に記号をつけましょう

Using this notation is best practice.

この表記法を使うのがベストです

It will help the translator know how to reorder the text and the parameters so that it fits the local language.

翻訳者がテキストとパラメータの並べ替えを理解しやすいので

Now let's look at how we can use this method

ローカライズする時に役立ちますではこのメソッドをどのように使えば

to format temperatures within our app.

気温をフォーマットできるのか説明しましょう

Within the string.xml file, we declared the format temperature string resource.

string．xmlでformat＿temperatureという文字列リソースを宣言します

We use XLIFF tags to denote that this is where the decimal temperature value will go.

XLIFFのタグで10進型の気温の場所を示し

This is followed by the unit code character for the degrees symbol.

これに温度を表す単位コードの文字が続きます

In the utility class, in the format temperature method,

utilityクラスのformatTempertureメソッドでは

we can use this string resource.

この文字列リソースを使うことができます

Remember that in this method, we take in a temperature

このメソッドは気温と一緒に

and a user's preference for metric or imperial.

ユーザが好む温度の表示方法も理解し

Then we return the converted temperature.

摂氏や華氏に変換した温度を返します

We're going to modify this method so that it also returns

このメソッドを修正して温度を示す値の後ろに

the formatted string with a degrees symbol after the value.

摂氏の記号を含むフォーマットの文字列を返しましょう

In order to do this, we need to pass in a context,

そのためにはコンテキストから宣言済みの

From the context we can get access to the string resource ID

文字列リソースのIDにアクセスして

that we declared earlier. Then we passed in any additional parameters for that string template.

文字列テンプレートに関する追加パラメータを渡します

In this case we only have one parameter so we pass in the temperature value.

今回はパラメータが1つなので気温の値を渡します

Then this fully formatted string gets returned to the caller.

するとフォーマットされた文字列が呼び出し側へ返されます

This method is used in the forecast list, as well in the detail page.

このメソッドは予報リストと詳細ページで使われるので

So we also have to update the code there so that it would compile with this new parameter.

詳細ページのコードもアップデートします

And this is what the app looks like after the change.

変更後のアプリはこのようになります

Go ahead and make the change in your code to add a string resource

では皆さんのアプリもコードを変更して

for displaying temperature in degrees.

摂氏で気温が表示されるよう文字列リソースを加えてください

Check this box when you're done.

完了したらチェックを入れましょう

And remember, use this notation

今後フォーマットした文字列が必要な時は

going forward, for when you need to format strings.
