I've tried every method I've seen for disabling the softkeyboard in an android app when using a webview. Nothing works. Instead, I decided I'd use a custom softkeyboard http://www.fampennings.nl/maarten/android/09keyboard/index.htm (SO keeps giving me an Object object error when trying to format that link). Then I noticed that the last step is to register the edittexts...which a webview wouldn't be using.
At this point I'll take any solution I can get, I simply would like to have a custom keyboard for a calculator app that supports hex. If there's a way to make a custom softkeyboard work with a webview: I'll take that answer. If there's a way to completely disable the softkeyboard and I could just write one as part of the webview: that'd be great too.
