Re: [kivy-users] numeric keyboard for use on android

[qua-non non]

1) set TextInput_instance.input_type to 'numeric' or 

2) use a VirtualKeyboard http://kivy.org/docs/api-kivy.uix.vkeyboard.html

Hi there

Just in case it helps, I struggled here too. Although the "input_type" in the 1.8.0 TextInput will probably do the job for you, here is an example of how to implement a raw custom keyboard...

https://github.com/Zen-CODE/kivybits/tree/master/Keyboard
 
I found the docs here pretty unhelpful, and I plan on updating them once I neaten up this example and get a better understanding...

Cheers

Thanks, Zen-code, I did actually use the input_type and it still opened a text based layout, I am using the system keyboard as I need the Hardware.hideKeyboard() as the keyboard was not disappearing after the app loaded the output to the screen, and when I used the vkeyboard, it was tiny and would not change orientation when the phone did.

So you set input_type http://kivy.org/docs/api-kivy.uix.textinput.html#kivy.uix.textinput.TextInput.input_type

and the kayboard shown is still alphanumeric?

Have you updated your py4a removed any old cached libs/dowloads?

Should it be "number" or "numeric", I used number as that is what the docs said to use: "input_type is an OptionsProperty and defaults to ‘text’. Can be one of ‘text’, ‘number’, ‘url’, ‘mail’, ‘datetime’, ‘tel’, ‘address’."

[qua-non non]

Yes it should be number.

Make sure you have removed the packages cache from your ~/buildozer/android/packages dir

and remove your app_dir/.buildozer.

This should force buildozer to rebuild your app using latest stable kivy.

I installed 1.8.0 through the ppa using ubuntu, I don't think I removed the packages cache though from .buildozer, I will try that thanks.

One easy way to check if your app was build using the feature is to test if your TextInput shows selection handles. This feature was added after the input_type settings was introduced.

Thanks, qua-non, it is working now.
