Question

我已经在我的应用程序中使用FirebaseUI实现了一个RecyclerView，它将我带到一个特定的活动。我将此活动称为TicketDetailActivity。只有当我尝试将意图指向此活动并且适用于任何其他活动时，应用程序才会崩溃。可能是什么原因？

我还必须补充一点，我复制了'TicketDetailActivity＆＃39;来自另一个项目。那可能是与之相关的问题吗？

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

原来我的清单中的这一行：

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

应该是

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

现在效果很好！
