I recently had to work through this problem at my job. The Samsung Keyboard app has a single button for negative and decimal in some versions. I don't have a screenshot at the moment, I can try to grab one tomorrow. In order to get this button to show up when you select your EditText, on the XML side add:

android:inputType="numberDecimal|numberSigned"
android:digits="0123456789.-"

Then in your Activity / Fragment with the EditText, find the EditText and apply regex to ensure it's a number.

EditText editText = (EditText) findViewById(R.id.your_edit_text);

final String regex = "^\\-?(\\d*|\\d*\\.\\d+)$";

editText.setFilters(new InputFilter[]{ new InputFilter() {
    @Override
    public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
        //if we are adding text
        if (end > start) {
            String destinationString = dest.toString();
            String resultingTxt = destinationString.substring(0, dstart) + source.subSequence(start, end) + destinationString.substring(dend);
            // return null to accept the input or empty to reject it
            return resultingTxt.matches(regex) ? null : "";
        }
        // removing: always accept
        return null;
    }
}});

IMPORTANT: Also make sure you don't have a NumberKeyListener attached to the EditText. If you have a NumberKeyListener attached to the EditText the Samsung keyboard will hide the "-/." button you're trying to show.

Edit: If you don't want negative numbers you can also change the regex.

final String regex = "^(\\d*|\\d*\\.\\d+)$";

Try add comma ",". It may cause from different format of digits.

 <EditText
android:inputType="numberDecimal|number"
android:digits="0123456789.," />

Try this

By Xml

<EditText
android:inputType="numberDecimal|number"
android:digits="0123456789."
/>

By Java

input.setInputType(InputType.TYPE_CLASS_NUMBER);      //OR    
input.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);

This may helps you.
