为替代键创建自定义弹出式键盘

Question

我正尝试在android中为替代键创建自定义弹出式键盘。通过使用默认的键盘唯一定制，我可以做的是为弹出式键盘提供自定义布局。

我需要定制行为，以及（如一个在Gboard）比如，

（1）当按钮被长按，默认情况下它应该突出一个特定的密钥

（2）键可以通过移动手指被高亮显示，并且还选择（长按键和移动手指同时）

这些是我所引用的链接：

Creating a SoftKeyboard with Multiple/Alternate characters per key

How do you disable the SoftKeyboard key preview window?

这是弹出式键盘Gboard

任何建议/帮助将不胜感激。

谢谢。
