How do you use an integer from the resource file within a string in the same resource file?

Question

Is it possible to use an integer:

<integer name="minstringlength">7</integer>

within the same resource file but within a string:

<string name="nametooshort">Please enter a name longer than @integer/minstringlength characters</string>

Answer 1

I presume you want to use different minimum limits based on device configuration. You can't use the @integer/minstringlength in the string content, so I think the best you can do is have a format argument and build the string yourself like this:

<integer name="minstringlength">7</integer>
<string name="nametooshort">Please enter a name longer than %1$d characters</string>

int nameMinLength = getResources.getInt(R.integer.minstringlength, 0);
String nametooshort = getString(R.string.nametooshort, nameMinLength);

This assumes you are using an Activity/Fragment, otherwise you need a Context in order to use getResources() and getString().

Answer 2

It can not be done in resource file.

As xml contains static content and also from android string-resource doc there is no sub tag or nested tag of <string>

It task can done easily in java file

getResources().getString(R.string.minstringlength);
getResources().getInteger(R.integer.nametooshort);

OR Follow this post

<string name="meatShootingMessage">You shot %1$d pounds of meat!</string>

int numPoundsMeat = 123;
String strMeatFormat = getResources().getString(R.string.meatShootingMessage);
String strMeatMsg = String.format(strMeatFormat, numPoundsMeat);
