How to make the Java code to call a String from a XML file(In Android Studio)

Question

I have this code and I will like to make it multi language app. What I want is to use the Strings from the Strings.xml file under the directory of values.

Let's say I have a Toast...

Toast.makeText(getApplicationContext(), "WELCOME", Toast.LENGTH_LONG).show(); 

But I don't want to put the welcome in the java but to get it from the xml file, but How?

Solution 1

Put getString(R.string.welcome) instead of "WELCOME".

Solution 2

You have to use it like this:

getApplicationContext().getResources().getString(R.string.YOURSTRING);

Depending where in code, a simple

getString(R.string,ID);

could be enough.

Solution 3

In the res/values folder there is a file called strings.xml put there the String

Example

<string name="welcome">Welcome</string>

and change the Toast to

Toast.makeText(getApplicationContext(),R.string.welcome, Toast.LENGTH_LONG).show(); 

now if you want to add more languages create libraries in the res folder named according to the language : values-fr/ and place inside strings.xml
