如何使Java代码从XML文件调用String（在Android Studio中）

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?

Answer 1

把getString(R.string.welcome)改为“WELCOME”。

Answer 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.

Answer 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

Answer 4

You can add this line above your current code snippet:

String data=userInput.getEditableText().toString();

Here, userInput is the id of your EditText tag in xml file.

And just change the original line of your code to:

Toast.makeText(getApplicationContext(), "You entered "+data, Toast.LENGTH_LONG).show();

Answer 5

String file

<string name="hi"> Hi  </string>
<string name="ten"> out of 10  </string>
<string name="youHaveScored"> you have Scored </string>

Java file

String finalScore = getString(R.string.hi) +name+ getString(R.string.youHaveScored)+score+ getString(R.string.ten);
Toast.makeText(getApplicationContext(),finalScore,Toast.LENGTH_LONG).show();
