Yes. Because the first contact with the keyboard, so after reading a keyboardDemo above method according Demo write a layout
I do not know why, methods are basically the same, the function will change under the response content. But that turned into a whiteboard, feeling no place can cause changes in this issue

This just set the keyboard to show and hide the function, nothing special,
And press figures show whiteboard okay.
keyboardView.setPreviewEnabled (false);
This is not displayed whiteboard, just click the button above, then enter a number in the EditText, the board is set to true

I suggest you create a new project, leaving only a text box and you customize the keyboard, and then the whole project package sent to the group, we will help you look.

But it seems too late to give back to answer
Join the theme
in AndroidManifest.xml
android: allowBackup = "true"
android: icon = "@ drawable / ic_launcher"
android: label = "@ string / app_name"
android: theme = "@ android: style / Theme.Dialog">
