我现在正在使用一个应用程序,它使用3个选项卡,每个选项卡都包含一个片段,我试图在每个片段中实现SwipeRefreshLayout.我相信我已经正确地创建了这个,但我继续得到错误:
android.view.InflateException: Binary XML file line #1: Error inflating class SwipeRefreshLayout Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.SwipeRefreshLayout" on path: DexPathList[[zip file "/data/app/com.ryan.brooks.fropllc.frop.app-1.apk"],nativeLibraryDirectories=[/data/app-lib/com.ryan.brooks.fropllc.frop.app-1, /vendor/lib, /system/lib]] at com.ryan.brooks.fropllc.frop.app.whatsGoingOnFragment.onCreateView(whatsGoingOnFragment.java:23)
现在我完全不知道造成这种情况的原因.如果有人能帮助我,那将非常感激.
这是我实现SwipeRefreshLayout的片段布局:
这是我的片段类,我在调用SwipeRefreshLayout.
public class WhatsGoingOnFragment extends Fragment { private SwipeRefreshLayout swipeLayout; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment View view = inflater.inflate(R.layout.whats_going_on_fragment, container, false); // Retrieve the SwipeRefreshLayout and ListView instances swipeLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_refresh_whats_going_on); // Set the color scheme of the SwipeRefreshLayout by providing 4 color resource ids swipeLayout.setColorScheme( android.R.color.holo_blue_bright, android.R.color.holo_green_light, android.R.color.holo_orange_light, android.R.color.holo_red_light); return view; } }
对于ID名称更改的所有3个片段,布局和类结构都完全相同.我真的不知道这里出了什么问题.再次感谢任何帮助!
您需要使用完整的包名称SwipeRefreshLayout
:
<android.support.v4.widget.SwipeRefreshLayout android:layout_ android:layout_ tools:context="com.ryan.brooks.fropllc.frop.app.whatsGoingOnFragment" android:id="@+id/swipe_refresh_whats_going_on"> <ScrollView android:layout_ android:layout_ android:background="#343434"></ScrollView> </android.support.v4.widget.SwipeRefreshLayout>
