Email address validation
suggest changeAdd the following method to check whether an email address is valid or not:
private boolean isValidEmailId(String email){ return Pattern.compile("^(([\\w-]+\\.)+[\\w-]+|([a-zA-Z]{1}|[\\w-]{2,}))@" + "((([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\.([0-1]?" + "[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\." + "([0-1]?[0-9]{1,2}|25[0-5]|2[0-4][0-9])\\.([0-1]?" + "[0-9]{1,2}|25[0-5]|2[0-4][0-9])){1}|" + "([a-zA-Z]+[\\w-]+\\.)+[a-zA-Z]{2,4})$").matcher(email).matches(); }
The above method can easily be verified by converting the text of an EditText
widget into a String
:
if(isValidEmailId(edtEmailId.getText().toString().trim())){ Toast.makeText(getApplicationContext(), "Valid Email Address.", Toast.LENGTH_SHORT).show(); }else{ Toast.makeText(getApplicationContext(), "InValid Email Address.", Toast.LENGTH_SHORT).show(); }
Found a mistake? Have a question or improvement idea?
Let me know.
