How do I check if my EditText fields are empty?

Question

I have 5 EditTexts in android. I would like to know if I could check if all 5 EditTexts are null. Is there any way to do this??

Answer 1

I did something like this once;

EditText usernameEditText = (EditText) findViewById(R.id.editUsername);
sUsername = usernameEditText.getText().toString();
if (sUsername.matches("")) {
    Toast.makeText(this, "You did not enter a username", Toast.LENGTH_SHORT).show();
    return;
}
