How to set TextField is empty using Text Utils in Android Studio?

Question

I am having a problem with Edit Text empty text.

If email and password textfield is empty, then the TextUtils gonna show on both edittext.
If the user press the exclamation icon, then the message"This field is required" gonna show up. Other than that, its gonna be exclamation only.

Below is my code in ASIDE

    etEmail = (EditText) findViewById(R.id.etEmail);
    etPassword = (EditText) findViewById(R.id.etPassword);
    String email = etEmail.getText().toString().trim();
    String password = etPassword.getText().toString().trim();

     if(TextUtils.isEmpty(email)&& TextUtils.isEmpty(password)) {
        etEmail.setError("This field is required");
        return;
    }
    else if(TextUtils.isEmpty(email)) {
        etEmail.setError("This field is required");
        return;
    }
    else if(TextUtils.isEmpty(password)) {
        etPassword.setError("This field is required");
        return;
    }
    else{
    }

etEmail = (EditText) findViewById(R.id.etEmail);
etPassword = (EditText) findViewById(R.id.etPassword);
String email = etEmail.getText().toString().trim();
String password = etPassword.getText().toString().trim();

if(TextUtils.isEmpty(email)&& TextUtils.isEmpty(password)) {
    etEmail.setError("This field is required");
    etPassword.setError("This field is required");
    return;
}
else if(TextUtils.isEmpty(email)) {
    etEmail.setError("This field is required");
    return;
}
else if(TextUtils.isEmpty(password)) {
    etPassword.setError("This field is required");
    return;
}
else{
}

Now it shows in the both Edittext fields.

displaying error is depend upon focus so once edittext will get focus it will display error. you can't set focus on multiple edittext. – Wasim K. Memon Mar 02 '16 at 08:30
