android.view.InflateException: Binary XML file line #7: Error inflating class Ge

写到手势识别的时候.

GestureOverlayView 根据自动提示,写成:

?

 <GestureOverlayView     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:layout_weight="1.0"    android:id="@+id/gesture"    />

?

?

运行程序报错.

android.view.InflateException: Binary XML file line #7: Error inflating class GestureOverlayView

但凡有android.view.InflateException: Binary XML file line??xxxx这种错误,就开始检查XML是否有书写错误,可能错误提示还不够完善...找得头痛.
最后视图修改为:

?

<android.gesture.GestureOverlayView      android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:layout_weight="1.0"    android:id="@+id/gesture"    />

?

问题解决.
