Samsung Galaxy Tab 4 - Keyboard set to InputTypes.ClassNumber does not show a dot/comma

Hi all,

I have a problem with my Samsung Galaxy Tab 4 - SoftKeyboard.
For a specific group of edit texts I want to show just a SoftKeyboard with numbers and a dot/comma (accepting dot or comma dependent from current culture setting via KeyListener).

My code snippet for getting this number keyboard is:

var _sensorOffset = View.FindViewById<EditText>(Resource.Id.editText_sensor_offset_value);
_sensorOffset.InputType = InputTypes.ClassNumber;
_sensorOffset.KeyListener = DigitsKeyListener.GetInstance("0123456789-" + 

This works fine for most of the devices, e. g. my Google Nexus 5 with Android M 6.0.

But for some devices it does not work, e. g. for Samsung Galaxy Tab 4.
There I always get a Number keyboard WITHOUT a dot/comma so it is not possible to enter floating point numbers.

I read through a lot of posts and discussions, but whatever I try it does not work.
I also tried proposals like using, e. g.

_sensorOffset.InputType = InputTypes.ClassNumber;

Always the same number soft keyboard shows up. The only workarounds I found are to:

a) Install another SoftKeyboard, e. g. the Jelly Bean Keyboard 4.3 -> works fine.


b) assign _sensorOffset.InputType = InputTypes.ClassText; -> not nice to allow entering letters and afterwards do a lot of validation checks.

I also read that this is a known issue for some Samsung Galaxy Devices that dot/comma is not visible on soft keyboard, but I cannot really believe this.

Did I miss something completely here? I will be very thankful for some hints.

Thanks in Advance and Best Regards


P.S. Attached are some screenshots:
1.) Google Nexus 5 with Android 6.0 -> works like expected
2.) Galaxy Tab 4 with Android 5.0.2 and Default Samsung Keyboard -> No dot/comma at all
3.) Galaxy Tab 4 with Android 5.0.2 and Jelly Bean Keyboard 4.3 -> dot/comma available, but some additional buttons shown.

    We experience the exact same problem and have identified the same workarounds. Did you ever find any other solution?

    For Samsung devices (resp. for the Samsung keyboard) you have to override InputType in your own EditText class, for example call it "EditTextNumericDecimal".

    And now do the override like this:

    public override InputTypes InputType
            return InputTypes.ClassNumber | InputTypes.NumberFlagDecimal;
            base.InputType = value;

    And yeah, I know this is messed up...

    Hello Andreas, hello Ljusnan,
    sorry, it is a long time ago when I have posted this thread. Today I saw your comments.
    We never found a solution for that. We have decided some point in time to life with the workaround.
    Every combination for InputType Flags we did in XML or programmatically in C# does not solve the problem for us.
    I did not tried the exact solution posted above by Ljusnan, but currently I don't have the time to try it out.
    Perhaps some point in time I will come back to this issue.
    Thanks and Best Regards
