Question

在某些国家/地区，我有一个由事件的sessios填充的recyclerView。我有一个微调器，用户可以在其中选择国家/地区，然后从api加载数据并将其显示在recyclerView中。当用户更改国家/地区时，将数据添加到recyclerView并刷新它是正常的。我想添加一个简单的代码，如果会话正在进行中，那么recyclerView必须滚动到会话的位置，但是当它如果我更改国家/地区会收到此错误消息

java.lang.IndexOutOfBoundsException: Inconsistency detected. Invalid view holder adapter positionViewHolder{3f69195a position=3 id=-1, oldPos=-1, pLpos:-1 no parent} androidx.recyclerview.widget.RecyclerView{870f167 GFED.... ......ID 0,417-860,570 #7f0800a3 app:id/mEA_recyclerView}, adapter:is.com.raisse.companionfornite.EventSessionsRecyclerViewAdapter@1e4e5b14, layout:is.com.raisse.companionfornite.EventsActivity$1@c950fbd, context:is.com.raisse.companionfornite.EventsActivity@706582b

滚动到活动现场，我已使用此代码

recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.HORIZONTAL, false) {
        @Override
        public void onLayoutCompleted(RecyclerView.State state) {
            super.onLayoutCompleted(state);
            Log.d("position===>", "" + mPositionEvent);
            scrollRecycler();
        }
    });

    private void scrollRecycler() {
    try {
        LinearSmoothScroller smoothScroller = new LinearSmoothScroller(this) {
            @Override
            protected int getHorizontalSnapPreference() {
                return LinearSmoothScroller.SNAP_TO_START;

            }
        };
        smoothScroller.setTargetPosition(mPositionEvent);
        recyclerView.getLayoutManager().startSmoothScroll(smoothScroller);
    } catch (Exception ex) {
        ex.printStackTrace();
    }

}

变量mPositionEvent是静态的，我可以通过onBindViewHolder中的recyclerViewAdapter对其进行更改

@Override
public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
    //...
    //some code here works perfeclty
    try {
        Date dateStart = format.parse(eventTimeStart);
        Date dateEnd = format.parse(eventTimeEnd);
        Date dateCurrent = format.parse(currentTime);

        long longStart = dateStart.getTime();
        long longEnd = dateEnd.getTime();
        long current = dateCurrent.getTime();

        if (current>=longStart && current<longEnd){
            holder.txtStatus.setText("Live");
            holder.txtStatus.setTextColor(Color.RED);
            holder.viewS.setBackground(ContextCompat.getDrawable(context,R.drawable.parallelogram_view_live));
            EventsActivity.mPositionEvent = position;
        }

        if(current>=longEnd){
            holder.txtStatus.setText("ENDED");
        }

    } catch (ParseException e) {
        e.printStackTrace();
    }


}

当位置为0时我会注意到什么，所以没有活动直播我没有任何错误

实际上，这是RecyclerView android中的错误。 Google尚未解决此问题，因此请尝试其他解决方案。使用try-catch处理这种情况。扩展您的layoutManager作为包装管理器来处理崩溃。例如。考虑一下

class WrapperGridLayoutManager : GridLayoutManager {

constructor(context: Context?, attrs: AttributeSet, defStyleAttr: Int, defStyleRes: Int) : super(
    context,
    attrs,
    defStyleAttr,
    defStyleRes
)

constructor(context: Context?, spanCount: Int) : super(context, spanCount)

constructor(context: Context?, spanCount: Int, orientation: Int, reverseLayout: Boolean) : super(
    context,
    spanCount,
    orientation,
    reverseLayout
)

override fun onLayoutChildren(recycler: RecyclerView.Recycler?, state: RecyclerView.State) {
    try {
        super.onLayoutChildren(recycler, state)
    } catch (e: Exception) {
        e.printStackTrace()
    }

}
}

Android RecyclerView IndexOutOfBoundsException检测到不一致。无效的视图支架适配器positionViewHolder
