"Android Development Experience" low version of Popupwindow init method null pointer exception problem

Yesterday, the tester submitted to me a bug, in version 2.3, when the pop-up Popupwindow, there will be a null pointer exception, in the high version no problem, the following is the error message (Find the same exception, my exception has been resolved)

Exception information: exception:null stack information: Android.widget.PopupWindow.setContentView (popupwindow.java:384) Android.widget.popupwindow.<init> (popupwindow.java:286) android.widget.popupwindow.<init> ( popupwindow.java:266) android.widget.popupwindow.<init> (popupwindow.java:223) Net.oschina.gitapp.widget.dropdownmenu.<init> (dropdownmenu.java:34) Net.oschina.gitapp.ui.ProjectActivity.initMoreMenu (projectactivity.java:255) NET.OSCHINA.GITAPP.UI.PROJECTACTIVITY.ACCESS$10 (projectactivity.java:254) net.oschina.gitapp.ui.ProjectActivity $3.onpostexecute (projectactivity.java:385) Net.oschina.gitapp.ui.projectactivity$3.onpostexecute ( projectactivity.java:1) Android.os.AsyncTask.finish (asynctask.java:417) android.os.asynctask.access$300 ( asynctask.java:127) Android.os.asynctask$internalhandler.handlemessage (asynctask.java:429) Android.os.Handler.dispatchMessage (handler.java:99) android.os.Looper.loop (looper.java:130) Android.app.ActivityThread.main (activitythread.java:3691) java.lang.reflect.Method.invokeNatIve (Native Method) Java.lang.reflect.Method.invoke (method.java:507) com.android.internal.os.zygoteinit$ Methodandargscaller.run (zygoteinit.java:912) com.android.internal.os.ZygoteInit.main (zygoteinit.java:670) Dalvik.system.NativeStart.main (Native Method)

This is due to the absence of a super (context) call in the constructor method, only the super (context) can be called in the first row of the constructor method.
