FirebaseRecyclerAdapter如果使用密钥库版本

营造出NoSuchMethodException我知道，从https://github.com/firebase/FirebaseUI-Android/issues/46，修复NoSuchMethodException：FirebaseRecyclerAdapter如果使用密钥库版本

确保您TaskViewHolder类是公共
如果您TaskViewHolder是一个内部类的如你的活动，确保它是静态的

该解决方案仅在我使用调试密钥库构建应用程序时起作用。但是在使用release keystore构建应用程序之后，我仍然得到NoSuchMethodException。 minifyEnabled =假

我在单独CommentHolder.java文件ViewHolder公共：

public class CommentHolder extends RecyclerView.ViewHolder 
    implements View.OnClickListener { 
TextView tvComment = null; 
TextView tvUser = null; 
TextView tvDate = null; 
String emailComment = ""; 
String commentKey, catalogKey; 

FirebaseAuth auth; 
FirebaseDatabase database; 
CommentHolder(View row) { 
    super(row); 
    auth=FirebaseAuth.getInstance(); 
    database=FirebaseDatabase.getInstance(); 

    tvComment = (TextView) row.findViewById(R.id.comment); 
    tvUser = (TextView) row.findViewById(R.id.user); 
    tvDate = (TextView) row.findViewById(R.id.datecomment); 

    row.setOnClickListener(this); 
} 

@Override 
public void onClick(final View v) { 

    if (auth.getCurrentUser() == null || auth.getCurrentUser().getEmail() == null) { 

     Toast.makeText(v.getContext(), "Harap login terlebih dahulu", Toast.LENGTH_LONG).show(); 
     return; 
    } 
    if (!auth.getCurrentUser().getEmail().equalsIgnoreCase(emailComment)) { 
     Toast.makeText(v.getContext(), "Anda hanya dapat mengedit komentar yang Anda buat", Toast.LENGTH_LONG).show(); 
     return; 
    } 


    final View form = ((Activity) v.getContext()).getLayoutInflater().inflate(R.layout.dialog_comment, null); 
    EditText etComment = (EditText) form.findViewById(R.id.editTextComment); 
    etComment.setText(tvComment.getText().toString()); 

    AlertDialog.Builder builder = new AlertDialog.Builder(v.getContext()); 

    builder 
      .setTitle("Komentar Anda") 
      .setView(form) 
      .setPositiveButton("Kirim", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialogInterface, int i) { 
        final EditText etComment = (EditText) form.findViewById(R.id.editTextComment); 
        DatabaseReference commentRef = database.getReference(MyConstants.FB_COMMENT) 
          .child(catalogKey).child(commentKey); 
        Comment comment = new Comment(auth.getCurrentUser().getUid() 
          , auth.getCurrentUser().getEmail(), etComment.getText().toString()); 
        commentRef.setValue(comment); 

       } 
      }) 
      .setNegativeButton("Batal", null) 
      .setNeutralButton("Hapus", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialogInterface, int i) { 
        DatabaseReference commentRef = database.getReference(MyConstants.FB_COMMENT) 
          .child(catalogKey).child(commentKey); 
        commentRef.removeValue(); 
       } 
      }) 
      .show(); 


} 

void bindModel(String catalogKey, String commentKey, String comment, String emailComment, String dateComment) { 
    tvComment.setText(comment); 
    String temp = emailComment.replaceAll("(?<=.).(?=[^@]*[email protected])", "*"); 
    tvUser.setText(temp); 
    tvDate.setText(dateComment); 
    this.emailComment = emailComment; 
    this.commentKey = commentKey; 
    this.catalogKey = catalogKey; 
}

}

FirebaseRecyclerAdapter代码：

mAdapter = new FirebaseRecyclerAdapter<Comment, CommentHolder>(Comment.class, R.layout.play_row 
      , CommentHolder.class, commentRef) { 
     @Override 
     public void populateViewHolder(CommentHolder commentHolder, Comment comment, int position) { 

      Date date = new Date((long) comment.getLastUpdate().get("date")); 
      SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault()); 
      String strDate = simpleDateFormat.format(date); 
      commentHolder.bindModel(catalogKey, getRef(position).getKey(), comment.getComment(), comment.getEmail(), strDate); 

     } 

    };

我Comment.java：

public class Comment { 
String uid; 
String email; 
String comment; 
HashMap<String, Object> lastUpdate; 

public Comment() { 
} 

public Comment(String uid, String email, String comment) { 
    this.uid=uid; 
    this.email = email; 
    this.comment = comment; 
    HashMap<String, Object> lastUpdateObj = new HashMap<>(); 
    lastUpdateObj.put("date", ServerValue.TIMESTAMP); 
    this.lastUpdate = lastUpdateObj; 


} 

public String getUid() { 
    return uid; 
} 

public String getEmail() { 
    return email; 
} 

public String getComment() { 
    return comment; 
} 

public HashMap<String, Object> getLastUpdate() { 
    return lastUpdate; 
} 
}

请修改您的问题以提供[mcve]，包括与您的崩溃相关的Java堆栈跟踪以及您实施的FirebaseRecyclerAdapter。 – CommonsWare

@CommonsWare是的，谢谢。刚刚添加了java堆栈跟踪和我的代码 – Plugie

只是一个猜测：尝试使'CommentHolder'构造函数'public'，看看会发生什么。 – CommonsWare

由于@CommonsWare猜测。将该公共添加到CommentHolder构造函数后，问题就解决了。

public CommentHolder(View row) { 
super(row); 
auth=FirebaseAuth.getInstance(); 
database=FirebaseDatabase.getInstance(); 

tvComment = (TextView) row.findViewById(R.id.comment); 
tvUser = (TextView) row.findViewById(R.id.user); 
tvDate = (TextView) row.findViewById(R.id.datecomment); 

row.setOnClickListener(this); 
}

@souttab请编辑您的评论，以提供一个最小，完整和可验证的例子:) – Plugie

仍然面临问题 –

虽然我的构造函数是公开的。因为我想使用ProGuard，所以我使用minifyEnabled为true。 – Sandra
