Removing spaces from a string

Question

I am trying to remove all spaces from a string obtained from user input, but for some reason it does not work for me. Here is my code.

public void onClick(View src) { switch (src.getId()) { case R.id.buttonGo: String input = EditTextinput.getText().toString(); input = String.replace(" ", ""); url = ur + input + l; Intent myIntent = new Intent(start.this, Main.class); myIntent.putExtra("URL", url); start.this.startActivity(myIntent); break; } } 

Answer 1

 String input = EditTextinput.getText().toString(); input = input.replace(" ", ""); 

Sometimes you only need to remove spaces at the beginning or end of a line (and not in the middle). If in this case you can use trim :

 input = input.trim(); 

Answer 2

When I read the numbers from the contact book, then it doesn’t work. I used

 number=number.replaceAll("\\s+", ""); 

This worked, and for the url you can use

 url=url.replaceAll(" ", "%20"); 

Answer 3

I also had this problem. To solve the problem of spaces in the middle of the line, this line of code always works:

 String field = field.replaceAll("\\s+", ""); 

Answer 4

Try the following:

 String urle = HOST + url + value; 

Then return the values ​​from:

 urle.replace(" ", "%20").trim(); 

Answer 5

String res = "Application" res = res.trim ();

o / p: application

Note: empty space, empty space is cropped or deleted
