答案 0 :(得分：1)
感谢亲爱的回复，问题出在xml
中<com.ortiz.touch.ExtendedViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
更改为
<com.nyt.nahw.ExtendedViewPager
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
它工作正常。

引起：java.lang.ClassNotFoundException：com.ortiz.touch.ExtendedViewPager
该课程确实存在吗？你清理过你的项目吗？
