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);
}
TicketDetailActivity：

public class TicketDetailActivity extends AppCompatActivity {
private DatabaseReference mBlockedTicket, mTicketCount;
Button book;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
book = (Button) findViewById(R.id.book_btn);
mTicketCount = FirebaseDatabase.getInstance().getReference().child("Total Ticket Count");
mBlockedTicket = FirebaseDatabase.getInstance().getReference().child("Ticket blocks").child("Arjun");
book.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent startIntent = new Intent(TicketDetailActivity.this, TicketInputActivity.class);
startActivity(startIntent);
finish();
/* // -------- UPDATE TICKET COUNT ------- //
mTicketCount.runTransaction(new Transaction.Handler() {
@Override
public Transaction.Result doTransaction( MutableData mutableData) {
if(mutableData.getValue()!=null)
{
mutableData.setValue((Long)mutableData.getValue()-1);
}
return Transaction.success(mutableData);
}
@Override
public void onComplete(DatabaseError databaseError, boolean b, DataSnapshot dataSnapshot) {
Intent startIntent = new Intent(TicketDetailActivity.this, TicketInputActivity.class);
startActivity(startIntent);
finish();
}
});
// ------- UPDATE TO BLOCKED TICKETS ------ //
mBlockedTicket.setValue("Blocked");*/
}
});
}
}

答案 0 :(得分：0)
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！
