Splitting words in editText?

Question

Android

How can I take the part of the editText up to the space and save it to a variable? I did this:
EditText namm;
String data = editText2.getText().toString();
for(i=0; i != data.length(); i++) {if (String.valueOf(data.charAt(i)) == " ") { namm = editText2.setSelection(z, i-1);
z = i;
values ​​put("nam", namm);
values ​​put("sv", "4");
db.insert("QW", "nam", values); }
}
But writes incompatibility of types.

Answer 1

String data = editText2.getText().toString();

String[] words = data.split(" ");

Answer 2

Thanks to all!
