Android RecyclerView异步更新数据导致的崩溃问题
之前写极光即时通讯UI的时候,发现的问题,今天突发奇想,来分享给大家.
问题症状:
如果绑定的集合List中的数据和RecycerView的数据不一致的时候 RecycerView就会崩溃
报错信息:
1 java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid item position 157(offset:157).state:588 2 at android.support.v7.widget.RecyclerView$Recycler.getViewForPosition(RecyclerView.java:3300) 3 at android.support.v7.widget.RecyclerView$Recycler.getViewForPosition(RecyclerView.java:3258) 4 at android.support.v7.widget.LinearLayoutManager$LayoutState.next(LinearLayoutManager.java:1803) 5 at android.support.v7.widget.LinearLayoutManager.layoutChunk(LinearLayoutManager.java:1302) 6 at android.support.v7.widget.LinearLayoutManager.fill(LinearLayoutManager.java:1265) 7 at android.support.v7.widget.LinearLayoutManager.scrollBy(LinearLayoutManager.java:1093) 8 at android.support.v7.widget.LinearLayoutManager.scrollVerticallyBy(LinearLayoutManager.java:956) 9 at android.support.v7.widget.RecyclerView$ViewFlinger.run(RecyclerView.java:2715)10 at android.view.Choreographer$CallbackRecord.run(Choreographer.java:725)11 at android.view.Choreographer.doCallbacks(Choreographer.java:555)12 at android.view.Choreographer.doFrame(Choreographer.java:524)13 at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:711)14 at android.os.Handler.handleCallback(Handler.java:615)15 at android.os.Handler.dispatchMessage(Handler.java:92)16 at android.os.Looper.loop(Looper.java:137)17 at android.app.ActivityThread.main(ActivityThread.java:4921)18 at java.lang.reflect.Method.invokeNative(Native Method)19 at java.lang.reflect.Method.invoke(Method.java:511)20 at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1027)21 at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:794)22 at dalvik.system.NativeStart.main(Native Method)解决方案:
mRecycler.setLayoutManager(new WrapContentLinearLayoutManager(this));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 (IndexOutOfBoundsException e) { e.printStackTrace(); } }}文章借鉴于:https://www.cnblogs.com/liushilin/p/6927612.html
