How do I restrict my EditText input to numerical (possibly decimal and signed) input?

I have read Android: Limiting EditText to numbers and How do I show the number keyboard on an EditText in android?. Unfortunately, none of them seems to fit my needs.

I want to restrict my EditText input to only numbers. However, I also want to allow signed and/or decimal input.

Here is my current code (I need to do this programmatically):

EditText edit = new EditText(this);



edit.setHorizontallyScrolling(true);

edit.setInputType(InputType.TYPE_CLASS_NUMBER);

With this, my EditText merrily restricts all input to numerical digits. Unfortunately, it doesn't allow anything else, like the decimal point.

If I change that line to edit.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL), the EditText accepts all input (which isn't what I want...).

I've tried combining flags (in desperation to see if it would work):

edit.setInputType(InputType.TYPE_CLASS_NUMBER);

edit.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL)

edit.setInputType(InputType.TYPE_NUMBER_FLAG_SIGNED)

That didn't work either (the EditText accepted all input as usual).

So, how do I do this?

Programmatically? So you would be against an XML layout solution?

I wouldn't be against one, as long as I can create an EditText on the fly.

The best way to do that programmatically is using the next method:

public static DigitsKeyListener getInstance (boolean sign, boolean decimal)

Returns a DigitsKeyListener that accepts the digits 0 through 9, plus the minus sign (only at the beginning) and/or decimal point (only one per field) if specified.

This solve the problem about the many '.' in EditText

editText.setKeyListener(DigitsKeyListener.getInstance(true,true)); // decimals and positive/negative numbers. 



editText.setKeyListener(DigitsKeyListener.getInstance(false,true)); // positive decimals numbers. 



editText.setKeyListener(DigitsKeyListener.getInstance(false,false)); // positive integer numbers.



editText.setKeyListener(DigitsKeyListener.getInstance(true,false)); // positive/negative integer numbers.

Use this. Works fine

input.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);

input.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

EDIT

kotlin version

fun EditText.onlyNumbers() {

    inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_DECIMAL or

        InputType.TYPE_NUMBER_FLAG_SIGNED

    keyListener = DigitsKeyListener.getInstance("0123456789")

}

Hi All I also had this problem. I use C# with Xamarin

Just a slight note that I hope someone else as well.

I have tried multiple of the methods mentioned here.

edittext1.SetRawInputType(Android.Text.InputTypes.ClassNumber | Android.Text.InputTypes.NumberFlagDecimal);

was the closest but still did not work. As Ralf mentioned, you could use

edit.setInputType(InputType.TYPE_CLASS_NUMBER |
InputType.TYPE_NUMBER_FLAG_DECIMAL |
InputType.TYPE_NUMBER_FLAG_SIGNED);

However in my C# I did not have this. instead you do it as follow:

edittext1.InputType = Android.Text.InputTypes.ClassNumber | Android.Text.InputTypes.NumberFlagDecimal;

Please note that the ORDER of these is important. If you put Decimal first, it will still allow you to type any Characters, where If Numer is first it is only numeric, but allows a decimal seperator!

TO set the input type of EditText as decimal use this code:

EditText edit = new EditText(this);

edit.SetRawInputType(Android.Text.InputTypes.NumberFlagDecimal | Android.Text.InputTypes.ClassNumber);

my solution:`

   char ch=s.charAt(start + count - 1);

   if (Character.isLetter(ch)) {

       s=s.subSequence(start, count-1);

       edittext.setText(s);

    }

The best way to do that programmatically is using the next method:

public static DigitsKeyListener getInstance (boolean sign, boolean decimal)

Returns a DigitsKeyListener that accepts the digits 0 through 9, plus the minus sign (only at the beginning) and/or decimal point (only one per field) if specified.

This solve the problem about the many '.' in EditText

editText.setKeyListener(DigitsKeyListener.getInstance(true,true)); // decimals and positive/negative numbers. 



editText.setKeyListener(DigitsKeyListener.getInstance(false,true)); // positive decimals numbers. 



editText.setKeyListener(DigitsKeyListener.getInstance(false,false)); // positive integer numbers.



editText.setKeyListener(DigitsKeyListener.getInstance(true,false)); // positive/negative integer numbers.

Use this. Works fine

input.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL | InputType.TYPE_NUMBER_FLAG_SIGNED);

input.setKeyListener(DigitsKeyListener.getInstance("0123456789"));

EDIT

kotlin version

fun EditText.onlyNumbers() {

    inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_DECIMAL or

        InputType.TYPE_NUMBER_FLAG_SIGNED

    keyListener = DigitsKeyListener.getInstance("0123456789")

}

Hi All I also had this problem. I use C# with Xamarin

Just a slight note that I hope someone else as well.

I have tried multiple of the methods mentioned here.

edittext1.SetRawInputType(Android.Text.InputTypes.ClassNumber | Android.Text.InputTypes.NumberFlagDecimal);

was the closest but still did not work. As Ralf mentioned, you could use

edit.setInputType(InputType.TYPE_CLASS_NUMBER |
InputType.TYPE_NUMBER_FLAG_DECIMAL |
InputType.TYPE_NUMBER_FLAG_SIGNED);

However in my C# I did not have this. instead you do it as follow:

edittext1.InputType = Android.Text.InputTypes.ClassNumber | Android.Text.InputTypes.NumberFlagDecimal;

Please note that the ORDER of these is important. If you put Decimal first, it will still allow you to type any Characters, where If Numer is first it is only numeric, but allows a decimal seperator!

my solution:`

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

   char ch=s.charAt(start + count - 1);

   if (Character.isLetter(ch)) {

       s=s.subSequence(start, count-1);

       edittext.setText(s);
