setText() multiple strings from xml

Question

Maybe a simple question - I need help to setText multiple strings from my strings.xml.

 mytext.setText(resources.getString(R.string.history_text1+R.string.history_text2));

So I mean I need to put 2 different text as one via one setText.

However with this syntax I have an error: android.content.res.Resources$NotFoundException: String resource ID #0xfe1e0079

Try this:

 mytext.setText(resources.getString(R.string.history_text1) + resources.getString(R.string.history_text2))

I tried it also this way but then I have a warning in Android Studio: Do not concatenate text displayed with setText. Use resource string with placeholders.. However I am using the placeholders... BUT seems it is working this way, just the warning is appearing

add empty string to string from resources mytext.setText("" + resources.getString(R.string.history_text1) + resources.getString(R.string.history_text2))

that did not remove the warning. The answer from @forpas helped. But thanks anyway!

The values:
R.string.history_text1 and R.string.history_text2
are integer numbers referencing the actual strings in resources.
By adding them you get another integer that references nothing, so you get:

Resources$NotFoundException

If you want to concatenate the 2 string values:

String value = resources.getString(R.string.history_text1) + resources.getString(R.string.history_text2)
mytext.setText(value);
