是的!你可以不写任何Java/Kotlin代码，只使用XML，使用我创建的这个小库，它在构建时这样做，所以你的应用程序不会受到它的影响:https://github.com/LikeTheSalad/android-stem

使用

你的字符串:

<resources>
    <string name="app_name">My App Name</string>
    <string name="welcome_message">Welcome to ${app_name}</string>
</resources>

构建后生成的字符串:

<!-- Auto generated during compilation -->
<resources>
    <string name="welcome_message">Welcome to My App Name</string>
</resources>

在你的字符串文件中使用这个

<string name="redeem_point"> You currently have %s points(%s points = 1 %s)</string>

并在代码中相应地使用

coinsTextTV.setText(String.format(getContext().getString(R.string.redeem_point), rewardPoints.getReward_points()
                        , rewardPoints.getConversion_rate(), getString(R.string.rs)));

问题的直接Kotlin解决方案:

strings.xml

<string name="customer_message">Hello, %1$s!\nYou have %2$d Products in your cart.</string>

kotlinActivityORFragmentFile.kt:

val username = "Andrew"
val products = 1000
val text: String = String.format(
      resources.getString(R.string.customer_message), username, products )

补充回答

当我第一次在接受的答案中看到%1$s和%2$d时，它毫无意义。这里有更多的解释。

它们被称为格式说明符。在xml字符串中，它们的形式是

%[parameter_index$][format_type] 

%: The percent sign marks the beginning of the format specifier. parameter index: This is a number followed by a dollar sign. If you had three parameters that you wanted to insert into the string, then they would be called 1$, 2$, and 3$. The order you place them in the resource string doesn't matter, only the order that you supply the parameters. format type: There are a lot of ways that you can format things (see the documentation). Here are some common ones: s string d decimal integer f floating point number

例子

我们将创建以下格式化字符串，其中灰色部分以编程方式插入。

我妹妹玛丽12岁了。

string.xml

<string name="my_xml_string">My sister %1$s is %2$d years old.</string>

MyActivity.java

String myString = "Mary";
int myInt = 12;
String formatted = getString(R.string.my_xml_string, myString, myInt);

笔记

I could use getString because I was in an Activity. You can use context.getResources().getString(...) if it is not available. String.format() will also format a String. The 1$ and 2$ terms don't need to be used in that order. That is, 2$ can come before 1$. This is useful when internationalizing an app for languages that use a different word order. You can use a format specifier like %1$s multiple times in the xml if you want to repeat it. Use %% to get the actual % character. For more details read the following helpful tutorial: Android SDK Quick Tip: Formatting Resource Strings

你可以使用MessageFormat:

<string name="customer_address">Wellcome: {0} {1}</string>

在Java代码中:

String text = MessageFormat(R.string.customer_address).format("Name","Family");

但是，你也应该阅读Elias Mårtenson关于Android复数处理“零”的回答。对某些值(如“零”)的解释存在问题。
