  1. POPrefixing string resource identifier to select alternate version at run time
    text
    copied!<p>Normally, I fetch a string value from a resource XML using:</p> <pre><code>String mystring = getResources().getString(R.string.mystring); </code></pre> <p>Now, I would like to select an alternate version of the string based on some runtime condition.</p> <pre><code>String selectivestring; if (someBooleanCondition) selectivestring= getResources().getString(R.string.mystring); else selectivestring= getResources().getString(R.string.theirstring); </code></pre> <p>So far so good, but since I have many such "alternative string pairs", I would like to methodically prefix one type (say, "my_") and the alternate type (say, "alt_"):</p> <pre><code>String selectivestring1; if (someBooleanCondition) selectivestring1= getResources().getString(R.string.my_string1); else selectivestring1= getResources().getString(R.string.alt_string1); . . . String selectivestring2; if (someBooleanCondition) selectivestring2= getResources().getString(R.string.my_string2); else selectivestring2= getResources().getString(R.string.alt_string2); </code></pre> <p>(The above code is for illustration only. What I eventually want to do is to parametrize this so that I can put this in a loop, array or own accessor)</p> <p>If there were a preprocessor in Java, I could have just used string concatenation to select "my_" vs. "alt_" prefix. But since I know there isn't, is there a way, workaround or suggestion to modify the string resource identifier at runtime, as outlined above?</p> <p><strong>Note:</strong> The alternate version of each string is <a href="https://stackoverflow.com/questions/12072134/get-string-from-different-values-folder-in-android">not</a> in a different language/locale. I am basically trying to keep the original and the alternate versions of the string together, next to each other, in the same resource file, so that I can easily compare the two. </p>
