Android IME:显示一个自定义弹出对话框(如 Swype 键盘)，可以在 TextView 中输入文本

问题描述

我想知道如何创建一个自定义弹出窗口，如下面屏幕截图中的那个(借自 Swype 键盘)，其中我可以有几个按钮，每个按钮都将一个字符串提交给当前已连接"" TextView (通过 .你必须做一些黑客攻击才能让它做你想做的事情，唯一好的文档就是源代码.

I'm wondering how I can create a custom pop-up like the one in the screenshot below (borrowed from the Swype keyboard), where I can have a couple of buttons, which each commit a string to the currently "connected" TextView (via a InputConnection).

Please note: this is an InputMethodService and not an ordinary Activity. I already tried launching a separate Activity with Theme:Dialog. However, as soon as that one opens I lose my focus with the TextView and my keyboard disappears (and with that my InputConnection is gone).

You can try using a PopupWindow. You'll have to do a bit of hacking to get it to do what you want and the only good documentation for it is the source.
