嘿伙计们，我正在创建类似于 whatsapp 的聊天应用程序，但在 RecyclerView 中面临 Childs Visibilties 的问题，它包含我的消息和来自服务器的消息我已经在单一布局中为我的消息和服务器消息定义了两个项目，我正在设置基于可见性在布尔值上；但项目没有正确渲染

适配器类：

public class MessageDetailsListAdapter extends RecyclerView.Adapter<MessageDetailsListAdapter.MessageViewHolder> {

private List<MessageModel> messagesList;
private Activity activityContext;
public MessageDetailsListAdapter(List<MessageModel> messagesList,Activity activityContext) {
    this.messagesList = messagesList;
    this.activityContext = activityContext;
}


@Override
public int getItemCount() {
    return messagesList.size();
}

@Override
public void onBindViewHolder(MessageViewHolder messageViewHolder, final int i) {
    final MessageModel msg = messagesList.get(i);
    if(msg.getIsMessageSentbyMe())
    {
        messageViewHolder.card_linear.setVisibility(View.GONE);
        messageViewHolder.messageTextMe.setText(msg.getMsgText());
        messageViewHolder.userNameMe.setText(msg.getSenderName());
        messageViewHolder.timeStampMe.setText(msg.getSentTime());
        messageViewHolder.card_linearMe.setOnLongClickListener(new OnLongClickListener() {

            @Override
            public boolean onLongClick(View v) {
                // TODO Auto-generated method stub
                Intent intent = new Intent(activityContext.getString(R.string.brMessageDetailsDeleteItem)); …
