Try to set the adapter after instantiating it. E.g.:
// Inside OnCreate
//Recycler View
mMainList = (RecyclerView) view.findViewById(R.id.main_list);
LinearLayoutManager manager = new LinearLayoutManager(getContext());
mMainList.setHasFixedSize(true);
mMainList.setLayoutManager(new LinearLayoutManager(getContext()));
mFirestore = FirebaseFirestore.getInstance();
officesList = new ArrayList<>();
officesListAdapter = new OfficesListAdapter(officesList);
// Here your adapter is initialised
mMainList.setAdapter(officesListAdapter);

Create your adapter object before set it on RecyclerView
// add below method in your adapter class
public void dataChanged(List<Offices> officesList){
this.officesList = officesList;
notifyDataSetChanged();// make sure dont forget to call this method
}
// create adapter object before set it on RecyclerView
LinearLayoutManager manager = new LinearLayoutManager(getContext());
mMainList.setHasFixedSize(true);
mMainList.setLayoutManager(new LinearLayoutManager(getContext()));
officesListAdapter = new OfficesListAdapter(null);// add this line here
mMainList.setAdapter(officesListAdapter);
mFirestore = FirebaseFirestore.getInstance();
officesList = new ArrayList<>();
// and finally update data on your adapter from your firebase onEvent() method
for (DocumentChange doc: queryDocumentSnapshots.getDocumentChanges()) {
if(doc.getType() == DocumentChange.Type.ADDED){
Offices offices = doc.getDocument().toObject(Offices.class);
officesList.add(offices);
}
}
officesListAdapter.dataChanged(officesList);// update from here

Check user online or offline icons

I have chat app and i have fragment and show in it my friends , and currently i think to add online and offline feature next to user name in my friend fragment, I wrote the code and it working without problem , But i need to add icon online or offline next to The Full name of users, In layout i added the icons but i can't control these in code, I want if user online.. online icon set visibilty visible and offline icon set visibilty invisible and i want if user offline.. online icon set invisible and offline icon set visible.. this is my problem just!
Note: The icons is ImageView...
I wrote comment above my problems in fisrt class and in layout xml..

Populate ImageView from BaseAdapter (Swipecards)

I am attempting to use the Swipecards library (https://github.com/Diolor/Swipecards) to build a tinder-esqe application. I am using a BaseAdapter to populate a layout with two text views and an image view that will be provided to the main SwipeFlingAdapterView. While both of the text fields are populated, I cannot get the image to appear on the cards. I have tried this implementation with both an ArrayAdapter and a BaseAdapter and the results are the same.
The activity layout (deal_page_layout)
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_height="match_parent"
android:layout_width="match_parent">
<com.lorentzos.flingswipe.SwipeFlingAdapterView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/swipe_fling_view"
app:rotation_degrees="10"
tools:context=".DealPage"
android:alpha="1.0"
app:max_visible="2"
app:min_adapter_stack="5"/>
</FrameLayout>
The layout being populated by the BaseAdapter (deal_card)
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="#+id/deal_card_image">
</ImageView>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/deal_card_title"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_margin="15dp"
android:gravity="center"

<TextView

android:layout_height="wrap_content"
android:id="#+id/deal_card_description"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_margin="15dp"
android:gravity="center"
android:textSize="20dp"/>
</RelativeLayout>
BaseAdapter class
public class DealBaseAdapter extends BaseAdapter {
private Context context;
private List<GrubbyDeal> dealList;
private LayoutInflater li;
public DealBaseAdapter(Context context, LayoutInflater li, ArrayList<GrubbyDeal> dealList){
this.context = context;
this.dealList = dealList;
this.li = li;
}
#Override
public int getCount(){
return dealList.size();
}
#Override
public Object getItem(int position){
return dealList.get(position);
}
#Override
public long getItemId(int position){
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
ViewHolder viewHolder;
//resuse a view if possible
if(convertView == null){
convertView = li.inflate(R.layout.deal_card,parent,false);
viewHolder = new ViewHolder();
viewHolder.img = (ImageView) convertView.findViewById(R.id.deal_card_image);
viewHolder.title = (TextView) convertView.findViewById(R.id.deal_card_title);
viewHolder.desc = (TextView) convertView.findViewById(R.id.deal_card_description);
convertView.setTag(viewHolder);
}
else {
viewHolder = (ViewHolder) convertView.getTag();
}
GrubbyDeal curDeal = dealList.get(position);
viewHolder.img.setImageURI(curDeal.getImageUri());
viewHolder.title.setText(curDeal.getTitle());
viewHolder.desc.setText(curDeal.getDescription());
return convertView;
}
//view holder class to hold cached findViewByID results
private static class ViewHolder {
public ImageView img;
public TextView title;
public TextView desc;
}
And the main activity (DealPage)
public class DealPage extends Activity {
private ArrayList<GrubbyDeal> dealList;
private DealBaseAdapter dealAdapter;
SwipeFlingAdapterView flingContainer;
#Override
public void onCreate(Bundle sis){
super.onCreate(sis);
setContentView(R.layout.deal_page_layout);
//add some awesome cat deals to the adapter
dealList = new ArrayList<>();
for(int i=0; i < 5; i++){
GrubbyDeal tmp = new GrubbyDeal(i);
dealList.add(tmp);
}
//add another type of cat deal to the list
dealList.add(new GrubbyDeal());
dealAdapter = new DealBaseAdapter(this, getLayoutInflater(), dealList);
flingContainer = (SwipeFlingAdapterView) findViewById(R.id.swipe_fling_view);
flingContainer.setAdapter(dealAdapter);
flingContainer.setFlingListener(new SwipeFlingAdapterView.onFlingListener() {
#Override
public void removeFirstObjectInAdapter() {
// this is the simplest way to delete an object from the Adapter (/AdapterView)
Log.d("LIST", "removed object!");
GrubbyDeal popped = dealList.remove(0);
dealList.add(popped);
dealAdapter.notifyDataSetChanged();
}
#Override
public void onLeftCardExit(Object dataObject) {
makeToast(DealPage.this, "Left!");
}
#Override
public void onRightCardExit(Object dataObject) {
makeToast(DealPage.this, "Right!");
}
#Override
public void onAdapterAboutToEmpty(int itemsInAdapter) {
dealList.add(new GrubbyDeal());
dealAdapter.notifyDataSetChanged();
Log.d("LIST", "notified");
}
#Override
public void onScroll(float scrollProgressPercent) {
View view = flingContainer.getSelectedView();
}
});
flingContainer.setOnItemClickListener(new SwipeFlingAdapterView.OnItemClickListener() {
#Override
public void onItemClicked(int itemPosition, Object dataObject) {
makeToast(DealPage.this, "Clicked!");
}
});
}
}
Am I missing something obvious? Is there some vastly superior library that I should be using? Thanks,
Ian

I would recommend using Picasso to load images into your imageview.
Picasso.with(context).load(imgurl).into(viewHolder.img);

The problem was formatting. I was attempting to use
Uri.parse("android.resource://com.thepackage.theapp/R.drawable.cat4.jpg");
but wasn't getting a valid Uri back. So instead I am using resource ids with picasso and the card works great!

Simply expanding a recyclerview to show a TextView

I've explored many ways to achieve this. But I'm much confused now. I tried many Githubs libraries but got confused. Also tried this but I don't think it allows a textview to be shown in expanded view: http://bignerdranch.github.io/expandable-recycler-view/
WHAT I WANT: A simple Recyclerview fetching some text from server for different items. On each item click, a layout or view should be expanded and TextView should become visible with respective fetched text from the server.
I have a simple RecyclerView with code following:
DataAdapter.java
public class DataAdapter extends RecyclerView.Adapter<DataAdapter.ViewHolder> {
private ArrayList<List> android_versions;
private Context context;
int i =0;
public DataAdapter(Context context,ArrayList<List> android_versions) {
this.context = context;
this.android_versions = android_versions;
}
#Override
public DataAdapter.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.row_layout, viewGroup, false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
viewHolder.tv_android.setText(android_versions.get(i).getAndroid_version_name());
}
#Override
public int getItemCount() {
return android_versions.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
TextView tv_android;
public ViewHolder(View view) {
super(view);
tv_android = (TextView)view.findViewById(R.id.tv_android);
}
}
List.java (Some functions aren't being used as of now)
public class List {
private String android_version_name;
private String descr;
private int android_image_url;
private String android_image_url1;
public String getAndroid_version_name() {
return android_version_name;
}
public String getDescr(){ return descr;}
public void setDescr(String descr) {
this.descr = descr;
}
public void setAndroid_version_name(String android_version_name) {
this.android_version_name = android_version_name;
}
public int getAndroid_image_url() {
return android_image_url;
}
public String getAndroid_image_url1() {
return android_image_url1;
}
public void setAndroid_image_url(int android_image_url) {
this.android_image_url = android_image_url;
}
public void setAndroid_image_url1(String android_image_url1) {
this.android_image_url1 = android_image_url1;
}
}

Unable to populate any Cards in RecyclerView, possible cause?

I am trying to populate CardView's inside a RecyclerView. Though I am able to log all the adapter values(to make sure they are non-empty) I can't populate any in the UI. Here is the Activity Code:
FoodActivity.class
public class FoodActivity extends AppCompatActivity
{
private RecyclerView foodView;
private List<Result> adapter_data;
private CustomPlacesAdapter adapter;
private LinearLayoutManager llm;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_food);
foodView = (RecyclerView)findViewById(R.id.foodRView);
adapter = new CustomPlacesAdapter(adapter_data);
adapter_data = new ArrayList<>();
llm = new LinearLayoutManager(this);
foodView.setLayoutManager(llm);
foodView.setAdapter(adapter);
doGetRequest("restaurants in los angeles airport");
}
private void doGetRequest(final String message)
{
ApiInterfacePlaces apiService =
ApiClientPlaces.getClient().create(ApiInterfacePlaces.class);
Call<PlacesPojo> call = apiService.getValues(message, Util.getKeyForPlaces());
call.enqueue(new Callback<PlacesPojo>()
{
#Override
public void onResponse(Call<PlacesPojo>call, Response<PlacesPojo> response)
{
try
{
Log.e("TAG",""+response.body().toString());
List<Result> response_res = response.body().getResults();
adapter_data = response_res;
adapter.notifyDataSetChanged();
}
catch (Exception e)
{
Toast.makeText(FoodActivity.this, "Check data connection", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onFailure(Call<PlacesPojo> call, Throwable t) {
// Log error here since request failed
Log.e("FAILURE", t.toString());
}
});
}
}
Here is the code to the RecyclerView's adapter:
CustomPlacesAdapter.class
public class CustomPlacesAdapter extends RecyclerView.Adapter<CustomPlacesAdapter.HotelsViewHolder>
{
private DataHolder d2 = new DataHolder();
public class HotelsViewHolder extends RecyclerView.ViewHolder
{
private TextView hotelName;
private Typeface face;
private ImageView hotel_logo;
private Context mcontext;
HotelsViewHolder(View itemView)
{
super(itemView);
mcontext = itemView.getContext();
hotelName = (TextView)itemView.findViewById(R.id.hotelName);
face = Typeface.createFromAsset(itemView.getContext().getAssets(), "Fonts/Roboto-Regular.ttf");
hotelName.setTypeface(face);
hotel_logo = (ImageView)itemView.findViewById(R.id.logoOfHotel);
}
}
private static class DataHolder
{
List<Result> feeds;
}
public CustomPlacesAdapter(List<Result> feeds)
{
this.d2.feeds = feeds;
}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
#Override
public HotelsViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.food_item, viewGroup, false);
HotelsViewHolder pvh = new HotelsViewHolder(v);
return pvh;
}
#Override
public void onBindViewHolder(HotelsViewHolder feedViewHolder, int i)
{
feedViewHolder.hotelName.setText(d2.feeds.get(i).getName());
Picasso.with(feedViewHolder.mcontext).load(d2.feeds.get(i).getIcon()).into(feedViewHolder.hotel_logo);
}
#Override
public int getItemCount()
{
if(d2.feeds!=null)
{
return d2.feeds.size();
}
else
{
return 0;
}
}
}
This is the CardView that I use:
