android - Android自定义键盘出现一半

Question

键盘显示已满，但由于某些原因，最后两行被隐藏了。我试图从 XML 更改键盘高度，但没有帮助。

键盘布局：

<?xml version="1.0" encoding="utf-8"?>

    android:keyHeight="@dimen/key_height"

Answer 1

检查日志后，发现如下错误：

E/Keyboard：解析错误：android.content.res.Resources$NotFoundException：来自可绘制资源 ID 的文件 res/drawable/ic_backspace_24dp.xml

0x7f0703ae

我更换了文件，一切都恢复正常。
