Здравствуйте! Разбираюсь с логикой отправки и приема сообщений, чтобы получать и отправлять сообщения в чат. Только не могу понять почему те сообщения которые я получаю прилетают справа ( с той же стороны, что и отправляю). Кто подскажет, как прописать чтоб распознавать полученные сообщения и помещать их слева? Привожу свой код ниже.
public class DataAdapter extends RecyclerView.Adapter<DataAdapter.ChatViewHolder> {
public static final int MSG_TYPE_LEFT = 1;
public static final int MSG_TYPE_RIGHT = 0;
ArrayList<String> messages;
LayoutInflater inflater;
DataChat dataChat;
public DataAdapter(Context context, ArrayList<String> messages) {
this.messages = messages;
this.inflater = LayoutInflater.from(context);
}
@NonNull
@Override
public ChatViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
switch (viewType) {
case MSG_TYPE_RIGHT:
View view = inflater.inflate(R.layout.item_chat, parent, false);
return new ChatViewHolder(view);
case MSG_TYPE_LEFT:
View v = inflater.inflate(R.layout.item_chat_left, parent, false);
return new ChatViewHolder(v);
default:
return null;
}
}
@Override
public void onBindViewHolder(@NonNull ChatViewHolder holder, int position) {
String msg = messages.get(position);
holder.tvMessage.setText(msg);
}
@Override
public int getItemCount() {
return messages.size();
}
@Override
public final int getItemViewType(int position) {
if (dataChat.isMine()) return MSG_TYPE_RIGHT;
else return MSG_TYPE_LEFT;
}
class ChatViewHolder extends RecyclerView.ViewHolder {
TextView tvMessage;
ChatViewHolder(View itemView) {
super(itemView);
tvMessage = itemView.findViewById(R.id.tvMessage);
}
}
static class DataChat {
private boolean isMine;
private String content;
DataChat(String message, boolean mine) {
content = message;
isMine = mine;
}
