[java] Android - how to replace part of a string by another string?

I have strings with some numbers and english words and I need to translate them to my mother tongue by finding them and replacing them by locallized version of this word. Do you know how to easily achieve replacing words in a string?

Thanks

Edit:

I have tried (part of a string "to" should be replaced by "xyz"):

string.replace("to", "xyz")

But it is not working...

You're doing only one mistake.

use replaceAll() function over there.

e.g.

String str = "Hi";
String str1 = "hello";
str.replaceAll( str, str1 );

I noticed that you commented in 2011 but i thought i should post this answer anyway, in case anyone needs to "replace the original string" and runs into this answer ..

Im using a EditText as an example

// GIVE TARGET TEXT BOX A NAME

 EditText textbox = (EditText) findViewById(R.id.your_textboxID);

// STRING TO REPLACE

 String oldText = "hello"
 String newText = "Hi";      
 String textBoxText = textbox.getText().toString();

// REPLACE STRINGS WITH RETURNED STRINGS

String returnedString = textBoxText.replace( oldText, newText );

// USE RETURNED STRINGS TO REPLACE NEW STRING INSIDE TEXTBOX

textbox.setText(returnedString);

This is untested, but it's just an example of using the returned string to replace the original layouts string with setText() !

Obviously this example requires that you have a EditText with the ID set to your_textboxID

MAY BE INTERESTING TO YOU:

In java, string objects are immutable. Immutable simply means unmodifiable or unchangeable.

Once string object is created its data or state can't be changed but a new string object is created.

In kotlin there is no replaceAll, so I created this loop to replace repeated values ??in a string or any variable.

 var someValue = "https://www.google.com.br/"
    while (someValue.contains(".")) {
        someValue = someValue.replace(".", "")
    }
Log.d("newValue :", someValue)
// in that case the stitches have been removed
//https://wwwgooglecombr/

String str = "to";
str.replace("to", "xyz");

Just try it :)
