【中文标题】Firestore RecyclerView 应用程序在运行时崩溃【英文标题】：Firestore RecyclerView app's crashing when run 【发布时间】：2021-10-17 22:45:33 【问题描述】：您好，我刚刚完成了我的代码并准备对其进行测试。运行时，它可以正常编译，但在打开应用程序时会崩溃。请问有谁知道我该如何解决这个问题？
我正在尝试制作一个 RecyclerView 以显示来自相应帖子的 cmets，并从 Firebase Firestore 中检索它。
我实现了 FirestoreRecyclerAdapter，这是我的 CommentsActivity：
public class CommentsActivity extends AppCompatActivity
private FirebaseFirestore firebaseFirestore;
private RecyclerView mFirestoreList;
private Toolbar toolbar;
private FirestoreRecyclerAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_comments);
toolbar = findViewById(R.id.newpost_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
firebaseFirestore = firebaseFirestore.getInstance();
mFirestoreList = findViewById(R.id.comments_List);
//Query
Query query = firebaseFirestore.collection("Posts");
//Recycler Options
FirestoreRecyclerOptions<BlogPost> options = new FirestoreRecyclerOptions.Builder<BlogPost>()
.setQuery(query, BlogPost.class)
.build();
adapter = new FirestoreRecyclerAdapter<BlogPost, BlogViewHolder>(options)
@NonNull
@Override
public BlogViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType)
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.comments_list_item, parent, false);
return new BlogViewHolder(view);
@Override
protected void onBindViewHolder(@NonNull BlogViewHolder holder, int position, @NonNull BlogPost model)
holder.username.setText(model.getUser_id());
holder.comment.setText(model.getComment());
holder.userImg.setImageURI(Uri.parse(model.image));
;
mFirestoreList.setHasFixedSize(true);
mFirestoreList.setLayoutManager(new LinearLayoutManager(this));
mFirestoreList.setAdapter(adapter);
@Override
public boolean onOptionsItemSelected(MenuItem item)
switch (item.getItemId())
case android.R.id.home:
onBackPressed();
return true;
return super.onOptionsItemSelected(item);
private class BlogViewHolder extends RecyclerView.ViewHolder
private TextView username;
private TextView comment;
private ImageView userImg;
public BlogViewHolder(@NonNull View itemView)
super(itemView);
username = itemView.findViewById(R.id.comment_detail_username);
userImg = itemView.findViewById(R.id.comment_detail_user_img);
comment = itemView.findViewById(R.id.comment_detail_text);
@Override
protected void onStop()
super.onStop();
adapter.stopListening();
@Override
protected void onStart()
super.onStart();
adapter.startListening();
我的博客帖子（模型）：
public class BlogPost extends BlogPostID
public String user_id;
public String image;
public String title;
public String desc;
public String thumbnail;
public String comment;
public Date timestamp;
public BlogPost()
public BlogPost(String user_id, String image, String title, String desc, String thumbnail, String comment, Timestamp timestamp)
this.user_id = user_id;
this.image = image;
this.title = title;
this.desc = desc;
this.thumbnail = thumbnail;
this.comment = comment;
this.timestamp = timestamp;
public String getUser_id()
return user_id;
public void setUser_id(String user_id)
this.user_id = user_id;
public String getImage()
return image;
public void setImage(String image)
this.image = image;
public String getTitle()
return title;
public void setTitle(String title)
this.title = title;
public String getDesc()
return desc;
public void setDesc(String desc)
this.desc = desc;
public String getthumbnail()
return thumbnail;
public void setthumbnail(String thumbnail)
this.thumbnail = thumbnail;
public String getComment()
return comment;
public void setComment(String comment)
this.comment = comment;
public Date getTimestamp()
return timestamp;
public void setTimestamp(Date timestamp)
this.timestamp = timestamp;
这是 Logcat：

【问题讨论】：
分享你的应用 gradle 文件 firebase 版本似乎有些问题。 @PriyankaRajput 完成 @sak 我更新了问题 尝试将 firestore 版本升级到最新版本。 【参考方案1】：您需要将 firebase 依赖项更新为最新的。将以下行添加到应用程序级别的 gradle。从所有依赖项中删除所有版本代码，如下所示 -
您可以点击链接Firebase
implementation platform('com.google.firebase:firebase-bom:28.3.1')
// When using the BoM, you don't specify versions in Firebase library
//dependencies
// Declare the dependency for the Firebase SDK for Google Analytics
implementation 'com.google.firebase:firebase-messaging'
implementation 'com.google.firebase:firebase-auth'
implementation 'com.google.firebase:firebase-core'
implementation 'com.google.firebase:firebase-storage'
implementation 'com.google.firebase:firebase-firestore'
implementation 'com.firebaseui:firebase-ui-firestore'
implementation 'com.google.firebase:firebase-analytics'
【讨论】：
我做到了，但现在我得到了这个：A problem occurred evaluating project ':app'. > No such property: config for class: com.google.gms.googleservices.GoogleServicesPlugin
分享你的项目级gradle
我尝试以另一种方式重做代码，但效果很好，但是您使用 BoM 的技巧很棒！以上是关于Firestore RecyclerView 应用程序在运行时崩溃的主要内容，如果未能解决你的问题，请参考以下文章
