有很多人遇到过这个例外，我尝试过这个例外的可用解决方案，但实际上没有一个能适用于我的情况。
所以我的问题是我的工具栏上有一个过滤器按钮，里面有三个项目1.升序，2。降序，3。具体日期。当我选择升序和降序项目时，数据会在recyclerview内正确填充。但是当我选择日期特定选项并显示一个日期选择器....数据没有填充在recyclerview内部，当我触摸屏应用程序崩溃并给我上述异常时。
我执行这些操作的片段代码： -
public class PendingOrders extends Fragment {
String filterString="date_desc";
String filterDateString="";
private int mDay,mMonth,mYear;
private static final String TAG = "PendingORDERS";
private RecyclerView mMessagesView;

CustomItemClickListener listener;
private PendingOrderAdapter mAdapter;
private Socket mSocket;
private Boolean isConnected = true;
public static final int DIALOG_FRAGMENT = 1;
String actualPrice,amount,total,filledAmount,orderPrice,proceeds,orderDate,orderType,orderId;
String currencyname,order,order1,orderType1 , orderDate1,idz;
public PendingOrders() {
}
@Override

super.onAttach(context);
mAdapter = new PendingOrderAdapter(context, mMessages,listener);

mSocket.on("pending_orders_data", orderCompletedData);
mSocket.connect();
}

答案 0 :(得分：1)
在选择日期选择器时，只需执行一项操作，然后在调用main函数之前添加这些行。
onClick
{
adapter.notifyDataSetChanged();
recyclerView.getRecycledViewPool().clear();
and then the rest code....
}
