Extract a line from an EditText

Question

How can we extract a line from a multiLine EditText ?

I tried this way, but I know that is not a good practice :

String street1 = \"\";
         


        

Answer 1

Try this,

String text=editText1.getText().toString().replace("\n", " ").trim();

Answer 2

Try using String.split(). Code example:

String multiLines = streetEt.getText().toString();
String[] streets;
String delimiter = "\n";

streets = multiLines.split(delimiter);

Now you have an array of streets.

Let's say, for example, your EditText reads "1st St.\nHighway Rd.\nUniversity Ave." (or is those 3 streets separated by line breaks, instead of you actually seeing \n). Following the code example I provided you,

• multiLines becomes "1st St.\nHighway Rd.\nUniversity Ave."

• streets = multiLines.split(delimiter); fills the array streets with the street names, i.e.

  • streets[0] = "1st St."
  • streets[1] = "Highway Rd."
  • streets[2] = "University Ave."

Answer 3

Try this:

String text = streetEt.getText();

String firstLine = text.substring(0,text.indexOf("\n"));
