Format string XXX is not a valid format string so it should not be passed to String.format

Question

I have android app and this string in resources:

Select up to %1$d people!

Thi

Answer 1

Try File -> Invalidate Caches / Restart..., it fixed the problem for me.

Answer 2

In my case invalidating cache with restart did not help, but having consistent formatting parameters (e.g. %s) across other the locales resolved the issue. I hope this might be helpful to someone in the future.

Answer 3

For the formatting of the string to be correct:

String.format(Locale.ENGLISH, itemView.context.getString(R.string.XXX), "%17") 

Also the special characters do not have to interfere with the injection of parameters. For that, take into account the exhaust outlets for special characters

From: <string name="XXX">% %1$s</string>

To: <string name="XXX">%1$s</string>

Finally XXX is "%17"

Good Luck.

Answer 4

You're probably missing the format method of the String class, If you're setting it in a TextView, the proper way is:

textView.setText(String.format(getResources().getString(R.string.create_group_select_people), countMax));

Answer 5

Try doing a 'clean project' followed by a close and reopen of Android Studio.

That fixed it for me, it looks like some minor Android Studio /Lint bug.

Answer 6

I just copied the code and it works well. so you may need to check some other place,Here are my suggestions.

1. clean project
2. check multi-language files
3. or just use String.format just like others said
