I have been trying to have a view layout using TabWidget. This is using Eclipse and Android 1.5. However, anytime I use TabWidget, I get a NullPointerException in Eclipse. This is even with the sample on http://developer.android.com/guide/tutorials/views/hello-tabwidget.html. I saw few threads that mention that TabWidget implementation is very flaky.
Has anyone seen similar issue? Attached is the stack trace: java.lang.NullPointerException at android.widget.TabWidget.dispatchDraw(TabWidget.java:105) at android.view.ViewGroup.drawChild(ViewGroup.java:1484) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1228) at android.view.ViewGroup.drawChild(ViewGroup.java:1484) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1228) at android.view.ViewGroup.drawChild(ViewGroup.java:1484) at android.view.ViewGroup.dispatchDraw(ViewGroup.java:1228) at android.view.View.draw(View.java:5841) at android.widget.FrameLayout.draw(FrameLayout.java:352) at com.android.layoutlib.bridge.Bridge.computeLayout(Bridge.java:400) at com.android.ide.eclipse.editors.layout.GraphicalLayoutEditor.computeLayout (Unknown Source) at com.android.ide.eclipse.editors.layout.GraphicalLayoutEditor.recomputeLayout (Unknown Source) at com.android.ide.eclipse.editors.layout.GraphicalLayoutEditor.activated (Unknown Source) at com.android.ide.eclipse.editors.layout.LayoutEditor.pageChange (Unknown Source) at org.eclipse.ui.part.MultiPageEditorPart$2.widgetSelected (MultiPageEditorPart.java:266) at org.eclipse.swt.widgets.TypedListener.handleEvent (TypedListener.java:228) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1561) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1585) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1570) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:1360) at org.eclipse.swt.custom.CTabFolder.setSelection(CTabFolder.java: 3242) at org.eclipse.swt.custom.CTabFolder.onMouse(CTabFolder.java:2017) at org.eclipse.swt.custom.CTabFolder$1.handleEvent(CTabFolder.java: 320) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1561) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1585) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1570) at org.eclipse.swt.widgets.Widget.notifyListeners(Widget.java:1360) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java: 3482) at org.eclipse.swt.widgets.Control.sendTrackEvents(Control.java:3024) at org.eclipse.swt.widgets.Control.actionProc(Control.java:122) at org.eclipse.swt.widgets.Display.actionProc(Display.java:362) at org.eclipse.swt.internal.carbon.OS.CallNextEventHandler(Native Method) at org.eclipse.swt.widgets.Widget.kEventControlTrack(Widget.java: 1106) at org.eclipse.swt.widgets.Control.kEventControlTrack(Control.java: 2097) at org.eclipse.swt.widgets.Widget.controlProc(Widget.java:375) at org.eclipse.swt.widgets.Display.controlProc(Display.java:862) at org.eclipse.swt.internal.carbon.OS.SendEventToEventTarget(Native Method) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3051) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java: 2384) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2348) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2200) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:495) at org.eclipse.core.databinding.observable.Realm.runWithDefault (Realm.java:288) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench (Workbench.java:490) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java: 149) at org.eclipse.ui.internal.ide.application.IDEApplication.start (IDEApplication.java:113) at org.eclipse.equinox.internal.app.EclipseAppHandle.run (EclipseAppHandle.java:193) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication (EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start (EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run (EclipseStarter.java:386) at org.eclipse.core.runtime.adaptor.EclipseStarter.run (EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke (NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke (DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:549) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:504) at org.eclipse.equinox.launcher.Main.run(Main.java:1236) RS --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
