Question

I am making an app that generates random numbers for android (you can find it hat https://github.com/JXPheonix/RNumGen ) and I need some way for an xml string to be dynamic (of sorts); it needs to change every time it is viewed.

I want the string to invoke a method that generates a random number. The string in my xml file goes something like this:

    <string name="number">Your number is</string>

and I want after the is for a method in java to be called upon, which would subsequently change the ending of the string. Any way to do this (whether or not it involves actually editing the strings.xml file?)

Answer 1

You’re going about it a round-about way. Instead of somehow making your string in your XML file dynamic, just use your string and append to it in code. Something like:

TextView textView = (TextView) findViewById(R.id.textView1);
textView.setText(getString(R.string.number) + yourRNGMethod());
