How do you set EditText to only accept numbers without decimals in Android?

Question

My EditText should only accept a 3 digit number, not any other decimal numbers. I used the below regular expression to do that but this is even accepting characters like "." and "-". So how do you avoid accepting decimal values?

Java:

pattern=Pattern.compile("[0-9]{0,2}");

XML:

android:digits="0123456789"
android:inputType="number"

then it accept decimal also. It should accept only 3 digit number not any thing else — Brinda K, Feb 12 '14 at 10:34

Please read question. It should accept only digits not any other characters like "." or "-" – Brinda K Feb 12 '14 at 10:39
I have checked out your conditions. After adding these two attributes the **EditText** field will not take any "." or "-" and it will take only 3 digits, not more than that. – Hamid Shatu Feb 12 '14 at 10:43
IMHO this should be the accepted answer. – dazed May 08 '23 at 11:04

I guess you should do it programmatically with the use of TextWacher class

editText.addTextChangedListener(new TextWatcher()
{
    Handler handler = new Handler();
    Runnable delayedAction = null;

    @Override
    public void onTextChanged( CharSequence s, int start, int before, int count)
    {}

    @Override
    public void beforeTextChanged( CharSequence s, int start, int count, int after)
    {}

    @Override
    public void afterTextChanged( final Editable s)
    {}
});

Event if the input is not accept decimal. In my case if i set text to input programmatically, the result will be decimal (added .0 at the end). So, to solve that i replace it when i set the text.

double myValue = 25000;
myInput.setText(String.valueOf(myValue).replace(".0", ""));

How do you set EditText to only accept numbers without decimals in Android?
