ビューホルダーの作成

public class MessageActivity extends AppCompatActivity { 

public static class MessageViewHolder extends RecyclerView.ViewHolder { 
    public TextView messageTextView; 
    public TextView messengerTextView; 
    public CircleImageView messengerImageView; 

    public MessageViewHolder(View itemView) { 
     super(itemView); 
     messageTextView = (TextView) itemView.findViewById(R.id.messageTextView); 
     messengerTextView = (TextView) itemView.findViewById(R.id.messengerTextView); 
     messengerImageView = (CircleImageView) itemView.findViewById(R.id.messengerImageView); 
    } 
    ..... 
} 

アダプタ

mFirebaseAdapter = new FirebaseRecyclerAdapter<Message, MessageViewHolder>(
      Message.class, 
      R.layout.item_message, 
      MessageViewHolder.class, 
      mFirebaseDatabaseReference.child(MESSAGES_CHILD)) { 

     @Override 
     protected void populateViewHolder(MessageViewHolder viewHolder, Message friendlyMessage, int position) { 
      viewHolder.messageTextView.setText(friendlyMessage.getText()); 
      viewHolder.messengerTextView.setText(friendlyMessage.getName()); 
      if (friendlyMessage.getPhotoUrl() == null) { 
       viewHolder.messengerImageView.setImageDrawable(ContextCompat.getDrawable(MessageActivity.this, 
         R.drawable.profilepic_placeholder)); 
      } else { 
       Glide.with(MessageActivity.this) 
         .load(friendlyMessage.getPhotoUrl()) 
         .into(viewHolder.messengerImageView); 
      } 
     } 
    }; 

私は数秒のアプリがクラッシュ中に、活動を開始するとアダプタ

mMessageRecyclerView.setLayoutManager(mLinearLayoutManager); 
mMessageRecyclerView.setAdapter(mFirebaseAdapter); 

の設定:(と私は

compile 'com.google.firebase:firebase-database:9.4.0' 
compile 'com.google.firebase:firebase-messaging:9.4.0' 
compile 'com.firebaseui:firebase-ui-database:0.5.3'

     @Override 
     protected void populateViewHolder(final MessageViewHolder viewHolder, Message friendlyMessage, int position) { 
      viewHolder.messageTextView.setText(friendlyMessage.getText()); 
      viewHolder.messengerTextView.setText(friendlyMessage.getName());
