Android之RecyclerView的原生Bug-Inconsistency detected. Invalid view holder adapter positionViewHolder{a1bbfa3 position=2 id=-1, oldPos=-1, pLpos:-1 no parent}，recyclerviewholder
今天在執行自己編寫的App時，突然發現App在執行時閃退，然後就查看了Android Studio的Log，發現了這個錯誤，上網查了一下，才知道是RecyclerView的原生Bug，在資料更新時會出現這個Bug，
錯誤解決的方式是自定義一個LayoutManager，重寫onLayoutChildren方法，在遇到這個異常時，直接丟擲異常。
public class WrapContentLinearLayoutManager extends LinearLayoutManager { public WrapContentLinearLayoutManager(Context context) { super(context); } public WrapContentLinearLayoutManager(Context context, int orientation, boolean reverseLayout) { super(context, orientation,reverseLayout); } public WrapContentLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) { super(context, attrs, defStyleAttr, defStyleRes); } @Override public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) { try{ super.onLayoutChildren(recycler, state); } catch (Exception e) { e.printStackTrace(); } } }
然後將RecyclerView的setLayoutManager的引數修改為WrapContentLinearLayoutManager。
程式碼如下：
recyclerView.setLayoutManager(new WrapContentLinearLayoutManager(mView.getContext())); 還有一種異常： java.lang.IllegalArgumentException: Called attach on a child which is not detached: ViewHolder{ec75dcb position=18 id=-1, oldPos=-1, pLpos:-1 not recyclable(1)} android.support.v7.widget.RecyclerView{b3515af VFED..... ......ID 0,0-1080,1230 #7f0900ec app:id/recycleView}, adapter:[email protected], layout:[email protected], context:[email protected] at android.support.v7.widget.RecyclerView$5.attachViewToParent(RecyclerView.java:818) at android.support.v7.widget.ChildHelper.attachViewToParent(ChildHelper.java:239) at android.support.v7.widget.RecyclerView.addAnimatingView(RecyclerView.java:1330) at android.support.v7.widget.RecyclerView.animateDisappearance(RecyclerView.java:3955) at android.support.v7.widget.RecyclerView$4.processDisappeared(RecyclerView.java:531) at android.support.v7.widget.ViewInfoStore.process(ViewInfoStore.java:242) at android.support.v7.widget.RecyclerView.dispatchLayoutStep3(RecyclerView.java:3789) at android.support.v7.widget.RecyclerView.dispatchLayout(RecyclerView.java:3447) at android.support.v7.widget.RecyclerView.onLayout(RecyclerView.java:3988) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.support.v4.widget.SwipeRefreshLayout.onLayout(SwipeRefreshLayout.java:611) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1762) at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1606) at android.widget.LinearLayout.onLayout(LinearLayout.java:1515) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.widget.RelativeLayout.onLayout(RelativeLayout.java:1079) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.widget.FrameLayout.layoutChildren(FrameLayout.java:325) at android.widget.FrameLayout.onLayout(FrameLayout.java:261) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.support.v7.widget.ActionBarOverlayLayout.onLayout(ActionBarOverlayLayout.java:443) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.widget.FrameLayout.layoutChildren(FrameLayout.java:325) at android.widget.FrameLayout.onLayout(FrameLayout.java:261) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1762) at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1606) at android.widget.LinearLayout.onLayout(LinearLayout.java:1515) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.widget.FrameLayout.layoutChildren(FrameLayout.java:325) at android.widget.FrameLayout.onLayout(FrameLayout.java:261) at com.android.internal.policy.DecorView.onLayout(DecorView.java:774) at android.view.View.layout(View.java:17702) at android.view.ViewGroup.layout(ViewGroup.java:5631) at android.view.ViewRootImpl.performLayout(ViewRootImpl.java:2519) at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:2234) at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1372) at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:6774) at android.view.Choreographer$CallbackRecord.run(Choreographer.java:926) at android.view.Choreographer.doCallbacks(Choreographer.java:735) at android.view.Choreographer.doFrame(Choreographer.java:667) at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:912) at android.os.Handler.handleCallback(Handler.java:761) at android.os.Handler.dispatchMessage(Handler.java:98) at android.os.Looper.loop(Looper.java:156) 05-07 15:19:42.096 3377-3377/com.xgh.application E/AndroidRuntime: at android.app.ActivityThread.main(ActivityThread.java:6523) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:942) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:832) 參考了各種資料，list的資料，要和adpater資料同步，例如，list.clear(),執行後，要立即呼叫notifyDataSetChanged()，而不是等到網路請求完後，在呼叫notifyDataSetChanged()。意思是每當list集合改變時，就立馬呼叫通知。 測試後不再報異常。希望對大家有幫助。
