RecyclerView上某个项目的OnClickListener不断使我的应用崩溃

Question

我已经在我的应用程序中使用FirebaseUI实现了RecyclerView，其中将我带到了特定的活动。 我将此活动称为TicketDetailActivity。 仅当我尝试将意图定向到此活动并且对于其他任何活动都运行良好时，该应用程序才会崩溃。 可能是什么原因？

我还必须补充一点，我从另一个项目复制了“ TicketDetailActivity”。 那么这可能是一个相关的问题吗？

我的Recyclerview Java代码：

 FirebaseRecyclerAdapter<Ticket_list, TicketsActivity.TicketsViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<Ticket_list, TicketsActivity.TicketsViewHolder>(

            Ticket_list.class,
            R.layout.ticket_item_layout,
            TicketsActivity.TicketsViewHolder.class,
            mEventsDatabase


                ) {
                    @Override
                    protected void populateViewHolder(TicketsActivity.TicketsViewHolder viewHolder, final Ticket_list model, int position) {

                        final String event_id = getRef(position).toString();

                        viewHolder.setEventName(model.getName());
                        viewHolder.setEventAddress(model.getAddress());

                        viewHolder.mView.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View view) {
                                //Toast.makeText(TicketsActivity.this, "Clicked on "+model.getName()+" ID: "+event_id, Toast.LENGTH_LONG).show();
                                try{
                                    Intent TicketDetailIntent = new Intent(TicketsActivity.this, TicketDetailActivity.class);
                                    startActivity(TicketDetailIntent);
                                    //finish();
                                }
                                catch(Exception e)
                                {
                                    Log.e("CRASH", "onRecyclerViewCLick: Failed");
                                    Toast.makeText(TicketsActivity.this, "Couldn't go to the window", Toast.LENGTH_LONG).show();
                                }
                            }
                        });

                    }
                };

                Tickets_list.setAdapter(firebaseRecyclerAdapter);
            }

Answer 1

原来这行在我的清单中：

    <activity android:name=".TicketsPage.TicketSummaryPage">

应该

    <activity android:name=".TicketsPage.TicketSummaryPage"/>

现在效果很好！
