Attempt to invoke virtual method ' int android.view.View.getImportantForAccessibility () '

Recently in the Do and list or the GridView related display appeared a problem, tidy up ideas, share out for everyone to refer to:

In fact, whether it is a ListView or a GridView may appear, and the reason is basically the same;

Short Msg:java.lang.NullPointerException

Long Msg:java.lang.NullPointerException:Attempt to invoke virtual method ' int Android.view.View.getImportantForAccessibility () ' On a null object reference//Build label:lenovo/passion/passion : 5.1.1/lmy47v/vibeui_v2.8_1530_5.200.1_st_p1c72:user/release-keys//Build Changelist:vibeui_v2.8_1530_5.200.1_st _p1c72//Build time:1437513185000//Java.lang.NullPointerException:Attempt to invoke virtual method ' int android.view.v Iew.getimportantforaccessibility () ' On a null object reference//at Android.widget.AbsListView.obtainView ( abslistview.java:2363)//at Android.widget.GridView.makeAndAddView (gridview.java:1433)//AT Android.widget.GridView.makeRow (gridview.java:361)//at Android.widget.GridView.fillDown (gridview.java:302)//AT Android.widget.GridView.fillFromTop (gridview.java:437)//at Android.widget.GridView.layoutChildren (Gridview.java : 1276)//at android.widget.AbsListView.onWindowFocusChanged (abslistview.java:2974)//AT Android.view.View.dispatchWindowFocusChanged (view.java:8714)//at android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1056)//AT Android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1060)//AT Android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1060)//AT Android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1060)//AT Android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1060)//AT Android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1060)//AT Android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1060)//AT Android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1060)//AT Android.view.ViewGroup.dispatchWindowFocusChanged (viewgroup.java:1060)//at android.view.viewrootimpl$ Viewroothandler.handlemessage (viewrootimpl.java:3309)//at Android.os.Handler.dispatchMessage (handler.java:102)/ /at Android.os.Looper.loop (looper.java:135)//at Android.app.ActivityThread.main (activitythread.java:5380)//AT Java.lang.reflect.Method.invoke (Native Method)//at Java.Lang.reflect.Method.invoke (method.java:372)//At Com.android.internal.os.zygoteinit$methodandargscaller.run ( zygoteinit.java:939)//at Com.android.internal.os.ZygoteInit.main (zygoteinit.java:734)

This way add a connection, because I find that the same reason that gallery appears,

The reason for this is that the GetView method of the corresponding adapter returns NULL, which appears as a null pointer phenomenon.

The solution is the same: look straight here.
