我的XML布局：

解决方法:

从发布的Logcat输出：

Caused by: androID.vIEw.InflateException: Binary XML file line #9:                                            Error inflating class com.boenka.mk.DrawPanel........Caused by: java.lang.classNotFoundException: com.boenka.mk.DrawPanel

您似乎在xml布局文件中意外拼错了自定义视图的名称：

<com.boenka.mk.DrawPanel    androID:ID="@+ID/signaturevIEw"    androID:layout_wIDth="fill_parent"    androID:layout_height="fill_parent" />

看看将com.boenka.mk.DrawPanel更改为com.boenka.mk.DrawingPanel是否可以解决问题.
