Question

I am making an alert dialog with edit text. I want that it will remain on screen until user input his email in it. How can I do that?? My code is as below:

final AlertDialog.Builder alert= new AlertDialog.Builder(this);
    alert.setMessage("Enter Email:");
    final EditText userid = new EditText(this);
    alert.setView(userid);
    userid.setInputType(InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS);
    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface dialog, int which) {
            if (userid.getText().toString().length()>0){
                userId = userid.getText().toString();               
                result();
            }else{

                Toast.makeText(getApplicationContext(), "Enter your email for future reference.", Toast.LENGTH_SHORT).show();
            }
        }
    });
    alert.show();

by clicking on any button the dialog dismisses. Please do tell how to retain the dailog on screen till i need it.Thanx in advance…

Do something like this…

boolean flagEmail = false;
Pattern pattern = Pattern.compile(EMAIL_PATTERN);
            if (validate(email.getText().toString().trim())) 
            {
                flagEmail = true;
            }

Calling the Function of validate

public boolean validate(String emailId) {
    matcher = pattern.matcher(emailId);
    return matcher.matches();
}

In your Condition, if flagEmail = true; then let dialog button get cancel, else get a Toast message.
