Organizing messages in user chat activity

i have created a custom view holder for my app to position sent messages to the right and received messages to the left which is working.
when messages are sent or received they are positioned as expected but when the chat activity is closed and reopened both the sent and received messages are positioned to the left and given the same color.
how can i make it remain as it is even when the app is closed and reopened?
below is my MessageAdapter.java
public class MessageAdapter extends RecyclerView.Adapter {
private static final int VIEW_TYPE_MESSAGE_SENT = 1;
private static final int VIEW_TYPE_MESSAGE_RECEIVED = 2;
private FirebaseAuth mAuth;
private Context mContext;
private List<Messages> mMessageList;
public MessageAdapter(List<Messages> mMessageList) {
//mContext = context;
this.mMessageList = mMessageList;
}
#Override
public int getItemCount() {
return mMessageList.size();
}
// Determines the appropriate ViewType according to the sender of the message.
#Override
public int getItemViewType(int i) {
mAuth = FirebaseAuth.getInstance();
String current_user_id = mAuth.getCurrentUser().getUid();
Messages c = mMessageList.get(i);
String from_user = c.getFrom();
String message_type = c.getType();
if (from_user == (current_user_id)) {
return VIEW_TYPE_MESSAGE_SENT;
} else {
return VIEW_TYPE_MESSAGE_RECEIVED;
}
}
// Inflates the appropriate layout according to the ViewType.
#Override
public RecyclerView.ViewHolder onCreateViewHolder (ViewGroup parent,int viewType){
View view;
if (viewType == VIEW_TYPE_MESSAGE_SENT) {
view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_message_sent, parent, false);
return new SentMessageHolder(view);
} else if (viewType == VIEW_TYPE_MESSAGE_RECEIVED) {
view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_message_received, parent, false);
return new ReceivedMessageHolder(view);
}
return null;
}
// Passes the message object to a ViewHolder so that the contents can be bound to UI.
#Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int i) {
Messages c = mMessageList.get(i);
switch (holder.getItemViewType()) {
case VIEW_TYPE_MESSAGE_SENT:
((SentMessageHolder) holder).bind(c);
break;
case VIEW_TYPE_MESSAGE_RECEIVED:
((ReceivedMessageHolder) holder).bind(c);
}
}
private class SentMessageHolder extends RecyclerView.ViewHolder {
TextView messageText, timeText;
SentMessageHolder(View itemView) {
super(itemView);
messageText = (TextView) itemView.findViewById(R.id.text_message_body);
timeText = (TextView) itemView.findViewById(R.id.text_message_time);
}
void bind(Messages message) {
messageText.setText(message.getMessage());
// Format the stored timestamp into a readable String using method.
// timeText.setText(Utils.formatDateTime(message.getCreatedAt()));
}
}
private class ReceivedMessageHolder extends RecyclerView.ViewHolder {
TextView messageText, timeText, nameText;
ImageView profileImage;
ReceivedMessageHolder(View itemView) {
super(itemView);
messageText = (TextView) itemView.findViewById(R.id.text_message_body);
timeText = (TextView) itemView.findViewById(R.id.text_message_time);
}
void bind(Messages message) {
messageText.setText(message.getMessage());
}
}
}
and my ChatActivity.java
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View action_bar_view = inflater.inflate(R.layout.child_custom_layout,null);
actionBar.setCustomView(action_bar_view);
mTitleView = findViewById(R.id.custom_bar_title);
mLastSeenView = findViewById(R.id.custom_bar_seen);
mProfileImage = findViewById(R.id.custom_appbar_image);
mChatAddBtn = findViewById(R.id.chat_add_btn);
mChatSendBtn = findViewById(R.id.chat_send_btn);
mChatMessageView = findViewById(R.id.chat_message_view);
mChatAddBtn.setVisibility(View.INVISIBLE);
mChatAddBtn.setEnabled(false);
mTitleView.setText(userName);
mAdapter = new MessageAdapter(messagesList);
mMessagesList = findViewById(R.id.messages_list);
mRefreshLayout = findViewById(R.id.message_swipe_layout);
mLinearLayout = new LinearLayoutManager(this);
mMessagesList.setHasFixedSize(true);
mMessagesList.setLayoutManager(mLinearLayout);
mMessagesList.setAdapter(mAdapter);
// loadMessages();
mImageStorage = FirebaseStorage.getInstance().getReference();
mRootRef.child("Chat").child(mCurrentUserId).child(mChatUser).child("seen").setValue(true);
loadMessages();

Here is the problem in the code
if (from_user == (current_user_id)) {
return VIEW_TYPE_MESSAGE_SENT;
} else {
return VIEW_TYPE_MESSAGE_RECEIVED;
}
You are checking equivalency with ==. This is not the right way of checking string equivalency. If you want to check equivalency you need to call equals() method of string as mentioned in below code.
if (from_user.equals(current_user_id)) {
return VIEW_TYPE_MESSAGE_SENT;
} else {
return VIEW_TYPE_MESSAGE_RECEIVED;
}
Try this. Hope this will help you.

How to show the contents of a list?

In my application I get some data from server and show this into my recyclerView.
I want show all of list content not show just item 0.
My adapter codes:
public class PostsAdapter extends RecyclerView.Adapter<PostsAdapter.ViewHolder> {
private ArrayList<Post> postList;
private Context context;
private ListItemClickListener itemClickListener;
public PostsAdapter(Context context, ArrayList<Post> allPostList) {
this.context = context;
postList = allPostList;
}
public void setItemClickListener(ListItemClickListener itemClickListener) {
this.itemClickListener = itemClickListener;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_post, parent, false);
return new ViewHolder(view, viewType, itemClickListener);
}
public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private ImageView imgPost;
private TextView tvPostTitle, tvPostCategory, tvPostDate;
private CardView mCardView;
private ListItemClickListener itemClickListener;
public ViewHolder(View itemView, int viewType, ListItemClickListener itemClickListener) {
super(itemView);
this.itemClickListener = itemClickListener;
// Find all views ids
imgPost = (ImageView) itemView.findViewById(R.id.post_img);
tvPostTitle = (TextView) itemView.findViewById(R.id.title_text);
tvPostCategory = (TextView) itemView.findViewById(R.id.post_category);
tvPostDate = (TextView) itemView.findViewById(R.id.date_text);
mCardView = (CardView) itemView.findViewById(R.id.card_view_top);
mCardView.setOnClickListener(this);
}
#Override
public void onClick(View view) {
if (itemClickListener != null) {
itemClickListener.onItemClick(getLayoutPosition(), view);
}
}
}
#Override
public int getItemCount() {
return (null != postList ? postList.size() : 0);
}
#Override
public void onBindViewHolder(PostsAdapter.ViewHolder mainHolder, int position) {
final Post model = postList.get(position);
// setting data over views
String title = model.getTitle().getRendered();
mainHolder.tvPostTitle.setText(Html.fromHtml(title));
String imgUrl = null;
if (model.getEmbedded().getWpFeaturedMedias().size() > 0) {
if (model.getEmbedded().getWpFeaturedMedias().get(0).getMediaDetails() != null) {
if (model.getEmbedded().getWpFeaturedMedias().get(0).getMediaDetails().getSizes().getFullSize().getSourceUrl() != null) {
imgUrl = model.getEmbedded().getWpFeaturedMedias().get(0).getMediaDetails().getSizes().getFullSize().getSourceUrl();
}
}
}
if (imgUrl != null) {
Glide.with(context)
.load(imgUrl)
.into(mainHolder.imgPost);
} else {
Glide.with(context)
.load(R.color.imgPlaceholder)
.into(mainHolder.imgPost);
}
String category = null;
if (model.getEmbedded().getWpTerms().size() >= 1) {
category = model.getEmbedded().getWpTerms().get(0).get(0).getName();
}
if (category == null) {
category = context.getResources().getString(R.string.default_str);
}
mainHolder.tvPostCategory.setText(Html.fromHtml(category));
mainHolder.tvPostDate.setText(model.getFormattedDate());
}
}
but in above code just show me item 0 , but I want show all of items.
how can I it?

Try this
for (int i = 0; i < model.getEmbedded().getWpTerms().size(); i++) {
for (int j=0;j<model.getEmbedded().getWpTerms().get(i).size();j++){
Log.e("DATA",model.getEmbedded().getWpTerms().get(i).get(j).getName());
}
}

String category = "";
for(int i=0; response.size();i++){
{
category = category + "," + model.getEmbedded().getWpTerms().get(i).get(i).getName();
}

If you have used recyclerview , its adapter has onBindViewHolder() method , which gives you a position variable. Use that to iterate through the list!
model.getEmbedded().getWpFeaturedMedias().get(position).getMediaDetails()

SetExpandAdapter in RecycleViewAdapter

I have RecycleView List with an ExpandableLinearLayout ( i use a third party library). In my ExpandableLinearLayout I have a ListView, with an custom ArrayAdapter.
I set my Adapter in the RecycleViewAdapter and submit one ArrayList that contains 4 ArrayLists and the position from the onBindViewHolder() method , too fill the different sections in the RecycleView.
I pass the data in the correct section but i get only the first element of each ArrayList. I Log some stuff and the problem is the position from the getView method in my ArrayAdapter is always 0..
I search and played around a bit but i didnt found a solution.. I hope somebody can help..

Set Radiobutton true onItemclick on listview

final RadioButton itemcheck = (RadioButton) item_view
.findViewById(R.id.listview_radiobutton);
if (itemcheck.isChecked()) {
itemcheck.setChecked(true);
} else {
itemcheck.setChecked(false);
}
itemcheck.setChecked(true);
}
My listview

private OnCheckedRadioButon onCheckedRadioButon;

return row;
}
private void setValueText(ViewHolder viewHolder, final int position) {

}
public interface OnCheckedRadioButon {
void onCheckedButton(Details pr);
}
class ViewHolder {
RadioButton radiobutton;
TextView listview_name;
}
}
It is working but if I click on another position of the listview then the previous radiobutton position is not unchecked.I want to uncheck all the previous ones and mark only one at a time.
Any help will be appreciated.

Use POJO classes (Setter or Getter) to manage this type of condition. Use boolean variable in that class and change its values according to the position true or false.
POJO Class Like :
public class CheckListSource {
public boolean isSelected;
public boolean isSelected() {
return isSelected;
}
public void setSelected(boolean selected) {
isSelected = selected;
}
}
In your adapter :
private ArrayList<CheckListSource > itemsData;
public ChildListAdapter(Activity activity, ArrayList<ChildListResponse> baseResponse) {
this.itemsData = baseResponse;
this.activity = activity;
}
In BindViewHolder Like :
viewHolder.checkParentView.setTag(itemsData.get(position));
viewHolder.checkParentView.setOnClickListener(checkedListener);
private View.OnClickListener checkedListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
CheckListSource childListResponse = (CheckListSource ) v.getTag();
if (childListResponse.isSelected())
childListResponse.setSelected(false);
else
childListResponse.setSelected(true);
notifyDataSetChanged();
}
};

Use a boolean array in your Activity. Each boolean value corresponds to a RadioButton.
If a RadioButton is checked, set its boolean value to true, and set all other boolean values in the array to false.
In the getView() of your Adapter, call your_radio_button.setChecked(your_boolean_array[position]).
Once the boolean array is modified, call your_adapter.notifyDataSetChanged().

Checkout this it works for me..
public class ProgramAdapter extends ArrayAdapter<KeyInformation> {
private final String TAG = "ProgramAdapter";
private List<KeyInformation> mList;
private Context mContext;

private int mSelectedPosition = -1;

}
mUserApllication ="";
mSelectedPosition = position;
mSelectedRB = (RadioButton) view;
}
});
String userApp = mList.get(position).packageName;
if(mUserApllication.equals(userApp)) {
mSelectedPosition = position;
}
if (mSelectedPosition != position) {
holder.mRadioButton.setChecked(false);
} else {

mSelectedRB = holder.mRadioButton;
}

holder.mTextView.setText(mList.get(position).lable);
if (position == 5) {

return convertView;

Please help me if anyone have solution for that particular problem .
Thanks in advance

Put a default in your switch statement
default:
viewHolder.mImageViewPriority.setBackgroundColor("Default color here for other priorities");
break;
and put default values in else part of all your if else conditions
