For allow user only can input lower case alphabet and number, how can I setup my EditText in a xml file ?
Sorry, I did not provide clear information. I just want to filter or check user's input.
AFAIK, your question is complicated to do. better get a input from user. then you can convert that string to lowercase using toLowerCase().

How do I set the input type for registration number. For example my university has specific format for registration number i.e. CIIT/SP17-mcs-044/Atk. I want CIIT/ATK is written already and Sp17-mcs-044 as a hint.
You can't define a random types of input type. You can only have one of these types as inputType.
If you want any custom behaviour, you might use TextWatcher and validate it
As #Tim has stated, the input type would be text over here and when user types in that EditText then check if the input is correct by using RegEx, and then show any message when the input is correct, for that you will need to add an OnTextChangedListener, about which you can learn more on official documentation.
Now, CIIT/ATK can be a TextView placed right before the EditText so it will be written already and will be uneditable. And yes, add that in final string after getting the input, like this:
finalInput = "CIIT/ATK" + input;
I have an Android EditText with suggestions enabled. My goal is not to disable suggestion (since i'm able to do that), but to skip some string values from them.
For example, suppose that i'd like to skip 'hello' word.
If i write 'he' in the EditText, my suggestions list shouldn't contain 'hello' since it's a string that has to be skipped. Is it possible?
Hope i explained myself, thanks
I have a issue. My applications require formatting the EditText's value while typing. I.E., a number that needs to be formatted with decimal and thousands separators. Example, I input 123456789, this number must appear 123.456.789.
How to I do this issue ? Thank all.
Нou can implement TextWatcher to your editText. Here're useful links for you:
How to use the TextWatcher class in Android?
http://developer.android.com/reference/android/text/TextWatcher.html
There you need to upgrade your number.
Or you can create your own customEditText.
I'm trying to learn android, I'm having trouble with user input
I've used editText to get users to enter a date and email which is all fine, then i add a hint
for these fields like so:
android:hint="#+string/DD/MM/YY"
android:hint="#+string/example#example.co.uk"
and i get multiple marker errors in the generated files :/
I don't think you can use special characters in string names. Give it a meaningful name like support_email. You can find more information here.
I am creating an android application. The first thing I'm creating is a login activity. I am trying to limit the username edittext just to text/numbers only (no special characters). Is there a way to adjust this in the xml file?
I dont think you can limit the characters from xml. You could always use a InputFilter, but specifically android provides UsernameFilterGeneric to filter valid user names. You could also use UsernameFilterGMail
As you already use in java Regular expression.called the same class here for checking for particular field.
let me know if you want some more if you didn't know about the RE.
