On-screen keyboard in dialog

Hi,
I have following problem with on-screen keyboard when using this library on touch device:

In demo app:
Open "Dialogs" in menu and tap "Sample 3/Run code" button.

Dialog opens, text box "Name" has focus so on-screen keyboard opens but closes instantly. If you tap on "Number" text box the same happens again. You need to tap twice to keep keyboard open.

Any idea how to fix this?

Thanks

在演示应用中打开 Dialogs，然后运行 Sample 3，并在触摸设备上复现 Name 和 Number 文本框的焦点行为。跟踪屏幕键盘周围的对话框和焦点处理；当键盘在初始获得焦点时以及点击任一字段后都保持打开，即表示完成。
