Android: Check if EditText is Empty when inputType is set on Number/Phone

Question

I have an EditText in android for users to input their AGE. It is set an inputType=phone. I would like to know if there is a way to check if this EditText is null

Answer 1

I found that these tests fail if a user enters a space so I test for a missing hint for empty value

EditText username = (EditText) findViewById(R.id.editTextUserName);

EditText password = (EditText) findViewById(R.id.editTextPassword);

// these hint strings reflect the hints attached to the resources

if (username.getHint().equals("Enter your username") || password.getHint().equals("Enter Your Password")){
      // enter your code here 

} else {
      // alls well
}
