I am trying to let my RecyclerView show the 'Message-rooms' items after I receive it from the server.
Currently, RecyclerView is on Fragment which is connected to BottomNavigationView.
I used 'MessageRoomAdapter' to set informations from the server response, but somehow, after successful communication, my RecyclerView shows just empty(white) screen.
Is it related to lifecycle problem?
I googled it for hours, but couldn't find answer.
MessageRoomAdapter.java

this.message_room_item_list = message_room_item_list;
}
public interface OnItemClickListener {
void onItemClick(View v, int position);
}
#NonNull
#Override
public MessageRoomAdapter.CustomViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_message_room, parent, false);
CustomViewHolder holder = new CustomViewHolder(view);
return holder;
}
#Override
public void onBindViewHolder(#NonNull MessageRoomAdapter.CustomViewHolder holder, int position) {
holder.tv_item_message_room_idx.setText(Integer.toString(message_room_item_list.get(position).getMessage_room_idx()));
holder.tv_item_message_user_idx.setText(Integer.toString(message_room_item_list.get(position).getUser_idx()));
holder.tv_item_message_user_nickname.setText(message_room_item_list.get(position).getUser_nickname());
holder.tv_item_message_message_idx.setText(Integer.toString(message_room_item_list.get(position).getMessage_idx()));

You are creating an empty list of m_message_room_item_list and setting that list to Adapter, then you are actually loading the list, but never updating the Adapter.
What you should do is create a method inside adapter like:
public void setList(ArrayList<MessageRoomItem> message_room_item_list) {
this.message_room_item_list = message_room_item_list;
notifyDataSetChanged();
}
and then call it in loadMessageRooms() perhaps, like:
public void loadMessageRooms(MessageRoomResponse messageRoomResponse){
switch (messageRoomResponse.getCode()){
case 100:
int num_of_message_rooms = messageRoomResponse.getMessageRoomResults().size();
for (int i = 0; i < num_of_message_rooms; i++){
MessageRoomItem messageRoomItem = new MessageRoomItem();
messageRoomItem.setMessage_room_idx(messageRoomResponse.getMessageRoomResults().get(i).getMessage_room_idx());
messageRoomItem.setUser_idx(messageRoomResponse.getMessageRoomResults().get(i).getUser_idx());
messageRoomItem.setUser_nickname(messageRoomResponse.getMessageRoomResults().get(i).getUser_nickname());
messageRoomItem.setMessage_idx(messageRoomResponse.getMessageRoomResults().get(i).getMessage_idx());
messageRoomItem.setContent(messageRoomResponse.getMessageRoomResults().get(i).getContent());
messageRoomItem.setTime(messageRoomResponse.getMessageRoomResults().get(i).getTime());
m_message_room_item_list.add(messageRoomItem);
}
messageRoomAdapter.setList(m_message_room_item_list);
break;
default:
break;
}
}

I have a RecyclerView, it has items in it. I need each item to have its own Activity, that is, we have item1 by clicking on it, Activity1 opens, there is also item2 about clicking on it, Activity2 is opened. Can this be done somehow? If so, how? I managed to make it so that when I clicked, the same Fragment opened, and the text changes depending on which item was clicked. But it doesn't quite suit me.

The positon param inside onBindViewHolder() method tells you which item of your RecyclerView clicked.
Use this to control your program and in out of onBindViewHolder() method you can get your item position by getAdapterPosition().
holder.Card.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
switch (position) {
case 0: {
// Start first activity.
break;
}
case 1: {
// Start Second activity.
break;
}
}
}
});

I never asked any question before but hope you'll get my point.
I am making a chat app in which I am using a RecyclerView to show messages. The problem is when I scroll the RecyclerView some of the items disappear from the top and the whole items messes up when I try to add a message it doesn't even scroll to bottom nor added in the ListView.
Here is my RecyclerView:
<android.support.v7.widget.RecyclerView
android:id="#+id/conversation_recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:layout_above="#id/typingConversationLayout"
android:layout_below="#id/topLayout_conversation_activity"
android:layout_marginBottom="-5dp"
android:paddingBottom="7dp" />
Initializing and setting the RecycerView:
linearLayoutManager = new LinearLayoutManager(this);
adapter = new ConversationRecyclerViewAdapter();
conversationRecyclerView.setAdapter(adapter);
conversationRecyclerView.setLayoutManager(linearLayoutManager);
linearLayoutManager.setStackFromEnd(true);
conversationRecyclerView.setHasFixedSize(true);
conversationRecyclerView.setNestedScrollingEnabled(false);
Here is my Adapter class:
private class ConversationRecyclerViewAdapter
extends RecyclerView.Adapter<ConversationRecyclerViewAdapter.ConversationViewHolder> {
#NonNull
#Override
public ConversationViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int i) {
Log.d(TAG, "onCreateViewHolder: Users Find started");
View conversationsView = LayoutInflater.from(parent.getContext()).inflate(
R.layout.layout_message_received, parent, false);
return new ConversationViewHolder(conversationsView);
}
#Override
public void onBindViewHolder(#NonNull final ConversationViewHolder holderConversation, int i) {
Log.d(TAG, "onBindViewHolder: Users Find started at position is " + i);
final int position = holderConversation.getAdapterPosition();
if (mOwnUser_1.get(position)) {
holderConversation.receivedMsgLayout.setVisibility(View.GONE);
holderConversation.sentProfileImg.setImageResource(mUserProfileImg_2.get(position));
holderConversation.sentMsg.setText(mUserText_3.get(position));
} else {
holderConversation.sentMsgLayout.setVisibility(View.GONE);
holderConversation.receivedProfileImg.setImageResource(mUserProfileImg_2.get(position));
holderConversation.receivedMsg.setText(mUserText_3.get(position));
}
Log.d(TAG, "onBindViewHolder: completed at " + position);
}
#Override
public int getItemCount() {
return mOwnUser_1.size();
}
public class ConversationViewHolder extends RecyclerView.ViewHolder {
RelativeLayout receivedMsgLayout, sentMsgLayout;
EmojiTextView receivedMsg, sentMsg;
CircleImageView receivedProfileImg, sentProfileImg;
public ConversationViewHolder(#NonNull View v) {
super(v);
receivedMsgLayout = v.findViewById(R.id.received_message_layout);
sentMsgLayout = v.findViewById(R.id.sent_message_layout);
receivedMsg = v.findViewById(R.id.received_message_text);
sentMsg = v.findViewById(R.id.sent_message_text);
receivedProfileImg = v.findViewById(R.id.received_message_user__profile_image);
sentProfileImg = v.findViewById(R.id.sent_message_user__profile_image);
}
}
}
Here I am adding data to ListView and displaying to the RecyclerView:
sendBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String msg = editText.getText().toString().trim();
if (TextUtils.isEmpty(msg)) {
editText.setError("Please add a message");
editText.requestFocus();
} else {
Log.d(TAG, "onClick: send Btn ADDED TEXT.. ");
mOwnUser_1.add(user);
mUserProfileImg_2.add(image);
mUserText_3.add(message);
editText.setText("");
editText.requestFocus();
adapter.notifyItemInserted(mOwnUser_1.size());
conversationRecyclerView.scrollToPosition(mOwnUser_1.size() - 1);
}
}
});
I don't know what i am doing wrong but it does not seem to work as i wanted.
Update Code:
The three listviews:
private ArrayList<Boolean> mOwnUser_1 = new ArrayList<>();
private ArrayList<Integer> mUserProfileImg_2 = new ArrayList<>();
private ArrayList<String> mUserText_3 = new ArrayList<>();
And the way of adding data to adapter:
mOwnUser_1.add(true);
mUserProfileImg_2.add(R.drawable.boy);
mUserText_3.add(edittext.getText().toString().trim());
adapter.notifyItemInserted(mOwnUser_1.size());
conversationRecyclerView.scrollToPosition(mOwnUser_1.size() - 1);
My Whole Conversation Activity Class:
public class ConversationActivity extends AppCompatActivity {
private static final String TAG = "ConversationActivity";

Currently I am also working on chat module, let me show you how am I doing this. I am going to show you in steps.
Step 1: make two separate layout for recyclerview items, one for message that has been sent from your side and one for message received from another side.
Step 2 : make two view holders to populate different layout according to your scenario, made in above step, like this:
public class ChatNewAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
private List<Chat> chats;
public ChatNewAdapter(List<Chat> chats) {
this.chats = chats;
}
#Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if (viewType == 0) {
View viewSend = (View) LayoutInflater.from(parent.getContext()).inflate(R.layout.item_message_send, parent, false);
return new ViewHolderSend(viewSend);
} else {
View viewReceive = (View) LayoutInflater.from(parent.getContext()).inflate(R.layout.item_message_received, parent, false);
return new ViewHolderReceive(viewReceive);
}
}
#Override
public void onBindViewHolder(final RecyclerView.ViewHolder holder, int position) {
switch (holder.getItemViewType()) {
case 0:
ViewHolderSend viewHolderSend = (ViewHolderSend) holder;
viewHolderSend.messageSend.setText(chats.get(position).getMessage());
break;
case 1:
ViewHolderReceive viewHolderReceive = (ViewHolderReceive) holder;
viewHolderReceive.messageReceived.setText(chats.get(position).getMessage());
break;
}
}
#Override
public int getItemCount() {
return chats.size();
}
#Override
public int getItemViewType(int position) {
if (chats != null && !chats.get(position).fromAdmin) {
return 0;
} else
return 1;
}
class ViewHolderSend extends RecyclerView.ViewHolder {
TextView messageSend;
public ViewHolderSend(View itemView) {
super(itemView);
messageSend = (TextView) itemView.findViewById(R.id.messageSend);
}
}
class ViewHolderReceive extends RecyclerView.ViewHolder {
TextView messageReceived;
public ViewHolderReceive(View itemView) {
super(itemView);
messageReceived = (TextView) itemView.findViewById(R.id.messageReceived);
}
}
public int addMessages(Chat chat) {
chats.add(chat);
notifyDataSetChanged();
return chats.size();
}
Step 3 : now in your activity:
public class Test extends AppCompatActivity {
RecyclerView chatList;
RecyclerView.LayoutManager mLayoutManager;
ChatNewAdapter adapter;
ImageView sendButton;
EditText messageEditText;
boolean keyboardUp = false;
boolean isRunning = false;
ArrayList<Chat> chats;
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_chat);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
isRunning = true;
setUpComponents();
}
public void setUpComponents() {
chatList = (RecyclerView) findViewById(R.id.chat_list);
chatList.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
chatList.setLayoutManager(mLayoutManager);
messageEditText = (EditText) findViewById(R.id.messageText);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);
sendButton = (ImageView) findViewById(R.id.send);
adapter = new ChatNewAdapter(chats);
chatList.setAdapter(adapter);
chatList.scrollToPosition(chatList.getAdapter().getItemCount() - 1);
messageEditText.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
if (keyboardShown(messageEditText.getRootView())) {
Log.d("keyboard", "keyboard UP");
if (keyboardUp == false) {
if (chats.size() > 0)
chatList.smoothScrollToPosition(chats.size() + 1);
keyboardUp = true;
}
} else {
Log.d("keyboard", "keyboard Down");
keyboardUp = false;
}
}
});
sendButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
final String message = messageEditText.getText().toString().trim();
if (!message.equals("")) {
Chat chat = new Chat();
String name = message;
chat.setMessage(name);
messageEditText.setText("");
adapter.addMessages(chat);
chatList.scrollToPosition(chatList.getAdapter().getItemCount() - 1);
} else {
Log.d("sending message Error", "error fetching dates");
}
}
});
}
private boolean keyboardShown(View rootView) {
final int softKeyboardHeight = 100;
Rect r = new Rect();
rootView.getWindowVisibleDisplayFrame(r);
DisplayMetrics dm = rootView.getResources().getDisplayMetrics();
int heightDiff = rootView.getBottom() - r.bottom;
return heightDiff > softKeyboardHeight * dm.density;
}
And this is my model class, ignore #PrimaryKey and #Required annotation it just because I am using Realm for local DB. In your case you wont required these annotation.
public class Chat extends RealmObject {
#PrimaryKey
#Required
public Long id;
public boolean fromAdmin;
#Required
public String message;
public int type;
public boolean isRead;
public boolean isSent;
public Date date;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public boolean isFromAdmin() {
return fromAdmin;
}
public void setFromAdmin(boolean fromAdmin) {
this.fromAdmin = fromAdmin;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public int getType() {
return type;
}
public void setType(int type) {
this.type = type;
}
public boolean isRead() {
return isRead;
}
public void setRead(boolean read) {
isRead = read;
}
public boolean isSent() {
return isSent;
}
public void setSent(boolean sent) {
isSent = sent;
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
I hope it will be helpful for you, you can ask further if you want to know anything else related to code.
RecyclerView as the name stands recycles the views. When binding data to a view, you need to ensure you set or reset all views that are touched in the adapter. Messups typically occur when there's data that is set only conditionally for some but not all items.
In particular:
if (mOwnUser_1.get(position)) {
holderConversation.receivedMsgLayout.setVisibility(View.GONE);
holderConversation.sentProfileImg.setImageResource(mUserProfileImg_2.get(position));
holderConversation.sentMsg.setText(mUserText_3.get(position));
} else {
holderConversation.sentMsgLayout.setVisibility(View.GONE);
holderConversation.receivedProfileImg.setImageResource(mUserProfileImg_2.get(position));
holderConversation.receivedMsg.setText(mUserText_3.get(position));
}
Both of these branches will need to reset the other layout back to visible.
Anyway with this kind of two-layout approach you are likely better off by having them as separate view types in your adapter. See How to create RecyclerView with multiple view type?
Working on android app' and I want to pass value from my textview that is in a row of a listview and put it in a fragment. I hear about convertView.gettag and settag method put I don't know how to deal with.

You were doing good, you need a Bundle to do this.
First of all create a String where you can keep the value of
holder.item_evaluation_nom.getText();
Then for example you do this :
String itemEvaluation = holder.item_evaluation_nom.getText();
This is the correct Bundle
EvaluationDetailHistoriqueFragment detail = new EvaluationDetailHistoriqueFragment();
Bundle bundle = new Bundle();
bundle.putString("text", itemEvaluation);
detail.setArguments(bundle);
Then to retrieve this you do this :
Bundle bundle = this.getArguments();
if (bundle != null) {
String itemEvaluation = bundle.getString("text", "");
}
hope it helps.
EDIT
You'll need to add an Adapter to your evaluations_historic_liste list.
You can do this doing :
evaluations_historic_liste.setAdapter(new EvaluationAdapter(getActivity(),mEvaluation));
mEvaluation is the List that you have to put data on it.
Then in your ListView add this :
evaluation_historic_liste.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> adapter, View v, int position, long id){
String itemEvaluation = (String) ((TextView)view.findViewById(R.id.item_evaluation_nom)).getText();
//or
String itemEvaluation=(evaluation_historic_liste.getItemAtPosition(position).toString());
}
}
i am chinese coder.i am not good at english,so just try hard to describe the question. thank you very much for your answer.
when i first into activity with RecyclerView and scroll,it is not smooth especially showing next item next ,but when i have scrolled the Recyclerview,it is work,and smooth . some coder say we can't do much work on onCreateViewHolder() and onBindViewHolder() , but i can not get it.
here is my code:
fragment
