Scarily this looks very red in Android Studio: Conclusion This error will persist until you've added your placeholders to the string resource. I found this out when I tried to refactor all my Java in one go and sadly the error message isn't as clear as it could be:įormat string 'resourceSeries' is not a valid format string so it should not be passed to String.format If you refactor your Java before your strings AndroidStudio will alert you to the fact that you can't perform a substitution. String eatingText = activity.getString(R.string.wordwordnumber, "apples", "pears", 3) A note on refactoring order Simply indicate in the string which argument should be placed into the placeholder (so %2 for the second, %6 for the sixth etc.) and pass the relevant number of arguments: I eat %1$s and %2$s %3$d times a day. You can use multiple placeholders in your strings, even mixing text and numbers.

In this case we pass item.getLanguage() as the argument: String languageText = activity.getString(R.string.language, item.getLanguage()) Performing the replacement.įinally we set the Android view element to have the value we've just built: tText(languageText) Īfter we've done that the inspection results will update to show our fix has applied and we can move onto the next one: Note the result now shows "no longer valid". Additional, optional, arguments can be passed to getString, separated by commas ( ,) and the placeholders are replaced by these. The first argument of the getString() method is mandatory and is the text to look up - in this case the language element of translation file ( R.string.language). Next we set the string value that we'll use later to apply to the language object. We declare the language object as being an Android view element that we find by ID ( R.id.txt_language): TextView language = findViewById(R.id.txt_language) It's not immediately clear what's happening here, so let's unpack it. String languageText = activity.getString(R.string.language, item.getLanguage()) So we make it: TextView language = findViewById(R.id.txt_language) tText(activity.getString(R.string.language) + ": " + item.getLanguage()) The original code, including declaring the language object, was: TextView language = findViewById(R.id.txt_language) Once you've updated your string it's time to refactor your code. If you're concatenating with a number you'd use $d instead. In this case %1 means "the first argument" and $s means "of type string" and I'll explain how that's used below. You'll note that I've added the ": " previously added by concatenation in Java and that I've also added %1$s which is our placeholder. For the example above that means taking the original string: Language Firstly we have to modify our strings for each translation to have a placeholder (or as many as we need) at the right place. Resolving this issue is a two step process. You may be thinking the above is a pretty tame example, and it is, but I'm a firm believer in doing things the right way where possible so let's sort this out! How do we fix this?

Once the concatenation is complete the results are displayed in a pop-up dialog about the content, like this (I've highlighted the element the above code worked on): The code above concatenated the Language element. There's three parts to this - first the localised word for "Language", followed by ": " (colon space) and then value of item.getLanguage() which finds the language of a piece of content. What the above code is doing is taking the language object (in this case an element that's displayed in the Android app) and setting the text that will be displayed. The offending code is highlighted by Android Studio and I've shown it below: tText(activity.getString(R.string.language) + ": " + item.getLanguage()) This can be a problem where word order changes in languages and the inspector shows the following guidance: Do not concatenate text displayed with setText. Running the inspector on eVitabu I found a number of places that we were concatenating strings from our translations with other data.

How to concatenate depends on your programming language and I've put some examples below: // PHPĮcho $string1.$string2.$string3 Concatenating in PHP // Java A simple concatenation of those three strings would get us applecatwallet. For example, consider three text stings: apple, cat, and wallet. To concatenate is to put two or more things together. In this post I'm going to look at the warning the inspector gives for concatenating strings with setText. These are really useful tools that can help find problems, fix bugs, and improve your style. Android Studio is based on Jetbrain's IntelliJ and, along with most (all?) products based on IntelliJ features code inspection and clean-up tools.
