Android 自定义软键盘（Android Studio）
Android custom soft keyboard (Android Studio)
我正在尝试创建一个包含多个活动的应用程序来监控用户与设备交互的不同方面。主要方面之一是来自自定义键盘的文本输入。我在网上看过几个不同的例子，但 none 似乎对我来说工作正常。不幸的是，当我尝试在 activity 中显示键盘时，它看起来像这样：http://puu.sh/jHQFQ/123ddd742b.jpg。老实说，我不知道为什么会这样。
这是我的键盘：`

根据 Xbalanqué 的回答，尝试在键盘标签中设置 keyHeight：
