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

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/

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.

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.

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

Just try it :)
