I have some EditText which is of "numberDecimal", and One Button. When user clicks on button, data goes to Database. So how to check EditText is empty or not. I am getting error when I try to parse the EditText.
To check an edittext is empty:
EditText ed = (EditText) findViewById(R.id.ed);
age = ed.getText().toString();
if (age.matches("")) {
Toast.makeText(this, "Empty", Toast.LENGTH_SHORT).show();
return;
}
You can also use equals() instead of matches()

I have a login
If user don't enter username or password and press "login" button, the EditText hint will warn you, like thislogin(turn red). How can I implement this?
I think you should set error instead
editText.setError(getString(R.string.error_required));
but if you want that
editText.setHint()
editText.setHintTextColor
Based on the image you have posted , it is very simple to show that hint when there is no data entered in username/password fields.
if(username.isEmpty())
{
usernameEditTextView.setHint("please enter username");
usernameEditTextView.setHintTextColor(R.color.Red);
}

How to make an Android Spinner with initial text "Select One"?
(36 answers)
Closed 9 years ago.
I have a spinner like this:
Spinner spinner = new Spinner(context);
spinner.setPadding(0, 10, 10, 0);
ArrayAdapter<ItemValue> aa = new ArrayAdapter<ItemValue>(context,
android.R.layout.simple_spinner_item,elemItemSet);
aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(aa);
Now I need a add a default/initial text programmatically (without using xml) & without adding into list 'elemItemSet'.
Is it possible?
To show defualt value(Select) at spinner,you have to add "Select" text into your array list at O index. And apply condition like "When the value of spinner is 'select' then show message to user like 'Select any value'".
I hope it will help you.
