我正在尝试ViewPagerIndicator
在我的项目中使用 Jake Wharton 的库,并按照此处列出的简单教程进行操作:
http://viewpagerindicator.com/
ClassNotFoundException
但是当我尝试运行我的项目时,我一直得到一个。
这是我的布局中的 XML:
<android.support.v4.view.ViewPager
android:id="@+id/day_pager"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" />
<com.viewpagerindicator.TitlePageIndicator
android:id="@+id/titles"
android:layout_height="wrap_content"
android:layout_width="fill_parent" />
这是我拥有的相应代码(dayPage
是一种ViewPager
类型)。
ArrayList<Integer> testData = new ArrayList<Integer>();
testData.add(12);
testData.add(13);
testData.add(22);
dayPage = (ViewPager) this.getActivity().findViewById(R.id.day_pager);
dayPage.setAdapter(new DayAdapter(testData));
//Bind the title indicator to the adapter
TitlePageIndicator titleIndicator = (TitlePageIndicator)this.getActivity().findViewById(R.id.titles);
titleIndicator.setViewPager(dayPage);
现在的值testData
是垃圾。
完整的堆栈跟踪是:

ViewPagerIndicator
我将该项目作为库导入到我的项目中,并仔细检查了包名是否完好无损,确实如此。我对我的项目进行了清理,但我仍然得到类未找到异常。我错过了什么吗?
