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    quot https   www google com br  quot      while  someValue contains  quot   quot              someValue   someValue replace  quot   quot    quot  quot         Log d  quot newValue   quot   someValue     in that case the stitches have been removed   https   wwwgooglecombr

It is working  but it wont modify the caller object  but returning a new String   So you just need to assign it to a new String variable  or to itself   string   string replace  to    xyz      or  String newString   string replace  to    xyz      API Docs  public String replace  CharSequence target  CharSequence replacement     Since  API Level 1      Copies this string replacing   occurrences of the specified target   sequence with another sequence  The   string is processed from the beginning   to the end    Parameters   target  the sequence to replace  replacement  the replacement sequence    Returns the resulting string   Throws NullPointerException  if target or replacement is null
