android - ViewPagerIndicator ClassNotFoundException吗？

我正在尝试在项目中使用Jake Wharton的ViewPagerIndicator库，并且遵循此处列出的简单教程:

http://viewpagerindicator.com/

但是，当我尝试运行我的项目时，我一直收到ClassNotFoundException。

这是我在布局中使用的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" />

这是我对应的代码(dayPage是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);

testData中的值现在是垃圾。

我将ViewPagerIndicator项目作为一个库导入到我的项目中，我再次检查了软件包名称是否完整。我对项目进行了清理，但仍然收到未找到的类异常。我想念什么吗？

最佳答案

很多人将此添加到lib的文件夹或将其导入(这是不正确的)

相反，您需要在“库”部分的“属性/android”对话框下添加整个项目(源和所有资源)(如下所示)

如果您不确定所做的操作，请尝试删除对库的所有引用，以使其不在库或引用的库文件夹中，并且不会显示在properties/java构建路径下的“libraries”选项卡

然后通过properties/android对话框将整个项目添加回去，进行干净的构建(有时要两次，感谢eclipse)，它应该可以正常工作。
