at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2913)

I think the error is self explanatory. As per your flow I can see you want to bind the messagelist actity layout with the Data binding of of MainActity class for which you might have layout as "activity_main.xml". For, As your messagelist activity binding layout name is "activity_messagelist.xml" so the generated binding class name will be "ActivityMessagelistBinding". Therefore, as per the logic of databinding the layout will bind with ActivityMessagelistBinding instead of ActivityMainBinding. So as a conclusion, you change the statement
private ActivityMainBinding activityMainBinding1;
activityMainBinding1 = DataBindingUtil.setContentView(this,R.layout.activity_messagelist);
to
private ActivityMessagelistBinding activityMessagelistBinding;
activityMessagelistBinding = DataBindingUtil.setContentView(this,R.layout.activity_messagelist);
Hope it should work.

Could you help me with the issue, please? Thank you very much.

Don't notify your adapter recursively,
Your code :
for (int i = 0; i < flowerList.size(); i++) {
FlowerModel flowerModel = flowerList.get(i);
mListFlowerAdapter.addFlower(flowerModel); // Called from here
}
Code from adapter
public void addFlower(FlowerModel flowerModel) {
myFlowers.add(flowerModel);
notifyDataSetChanged(); // Notifying everytime
}
Instead, you should add all data to adapter and notify only once : (Updated code)
for (int i = 0; i < flowerList.size(); i++) {
FlowerModel flowerModel = flowerList.get(i);
mListFlowerAdapter.addFlower(flowerModel);
}
mListFlowerAdapter.notifyDataSetChanged(); // Notify like this
Code from adapter
public void addFlower(FlowerModel flowerModel) {
myFlowers.add(flowerModel);
//notifyDataSetChanged(); Remove from here
}

Pass activity context to the adapter and use that context for populating item on list view.
private Context mContext;
public ListFlowerAdapter(Context context) {
myFlowers = new ArrayList<>();
this.mContext = context;
}
#NonNull
#Override
public MyViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View row = LayoutInflater.from(mContext).inflate(R.layout.row_item, parent, false);
return new MyViewHolder(row);
}
From activity send the activity context for initializing the adapter like this
mListFlowerAdapter = new ListFlowerAdapter(this);
And for adding a new item
public void addFlowers(List<FlowerModel> flowerModels) {
for (int i = 0; i < flowerModels.size(); i++) {
FlowerModel flowerModel = flowerModels.get(i);
myFlowers.add(flowerModel);
}
notifyDataSetChanged();
}
And successful response just send the list for updating the adapter
List<FlowerModel> flowerList = response.body();
mListFlowerAdapter.addFlowers(flowerList);
Hope this will help.

Try to remove this line:
mRecyclerView.setHasFixedSize(true);
And add this in the XML file:
android:fillViewport="true"
Without that line, your RecyclerView content initial height is 0 (empty list), and with the fixed size it can't grow although you add items to the adapter.

i try every possible way available on internet but dont get solution.
Anything wrong i am doing?
any idea how to run two recyclerview with above code.
thankx

You can do this-
<android.support.v4.widget.NestedScrollView>
<LinearLayout>
.
.
.
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
This is used to attach 2 or more scrolling views together and one more thing you can do is to make the height of recycler view as "wrap_content".
Hope this helps.

ArrayList not being displayed in RecyclerView

I'm trying to display an ArrayList of Integers inside of a RecyclerView, the Integer values in the ArrayList are downloaded from JSON, all that is done, the thing I need help with is to display them in a RecyclerView.
This is my code so far but the RecyclerView does not display anything.
All code updated to my current code
Here's part of the MainActivity:
public class MainActivity extends AppCompatActivity {
private ActivityMainViewModel viewmodel;

Here's the MainAdapter class:

}
#Override
public void onBindViewHolder(MainAdapter.ViewHolder holder, int position)
{
holder.rideHeight.setText(String.valueOf(rideList.get(position)));
}
#Override
public int getItemCount()
{
return rideList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView rideHeight;
public ViewHolder(View itemView) {
super(itemView);
rideHeight = (TextView) itemView.findViewById(R.id.rideHeight_textView);
}
}
}
row.xml:

</LinearLayout>
I know that it probably looks a mess but that's because I have been searching both on google and youtube on how to use RecyclerView so I might have mixed from different tutorials and tried somethings myself.
Thanks!
Edit: JsonData code added on request:
JsonData:
public class JsonData
{
public ObservableField<String> dropHeight = new ObservableField<>();
public ObservableField<String> rideCount = new ObservableField<>();
int eID;
int sID;
public JsonData()
{
dropHeight.set("");
rideCount.set("");
}
public void downloadFromSkistar()
{
if (SettingsActivity.submitClicked)
{
eID = SettingsActivity.x;
sID = SettingsActivity.y;
}
else
{
eID = 3206;
sID = 11;
}
try
{
URL url = new URL("https://www.skistar.com/myskistar/api/v2/views/statisticspage.json?entityId=" + eID + "&seasonId=" + sID + " ");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("GET");
// Starts the query
conn.connect();
int response = conn.getResponseCode();
Log.i("AndroidExample", "Response: " + response);
if (response == 200)
{
String json = getJson(conn.getInputStream());
JSONObject jsonObject = new JSONObject(json);
JSONArray jsonArray = jsonObject.getJSONArray("rideStatistics");
int reponame = 0;
int rHeight = 0;
for (int i = 0; i < jsonArray.length(); i++)
{
JSONObject skiRun = jsonArray.getJSONObject(i);
reponame += skiRun.getInt("height");
rHeight += skiRun.getInt("height");
MainActivity.rideList.add(new Integer(rHeight));
rHeight = 0;
}
final int height = reponame;
final int count = jsonArray.length();
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
dropHeight.set("" + height);
rideCount.set("" + count);
}
});
}
}
catch (Exception e)
{
Log.i("AndroidExample", "Error");
}
finally
{
}
}
private String getJson(InputStream stream) throws IOException
{
BufferedReader reader;
reader = new BufferedReader(new InputStreamReader(stream, "UTF-8"));
StringBuilder builder = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {

}
//Should be placed in finally

return builder.toString();
}
}

You can use like..
Model..to set value and get value
public class CustomModel {
private int it;
public int getIt() {
return it;
}
public void setIt(int it) {
this.it = it;
}
}
Adapter ...
private class MainAdapter extends RecyclerView.Adapter<MainAdapter.ViewHolder>{
public MainAdapter(ArrayList<CustomModel> list){
dataSet = list;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
View itemLayoutView = LayoutInflater.from(viewGroup.getContext()).inflate(
R.layout.row, null);
itemLayoutView.setLayoutParams(new RecyclerView.LayoutParams(RecyclerView.LayoutParams.MATCH_PARENT, RecyclerView.LayoutParams.WRAP_CONTENT));
MainAdapter.ViewHolder viewHolder = new MainAdapter.ViewHolder(itemLayoutView);
return viewHolder;
}
#Override
public void onBindViewHolder(ViewHolder viewHolder, int position) {
CustomModel cardModel = dataSet.get(position);
viewHolder.rideHeight_textView.setText(String.valueOf(cardModel.getId()));
}
#Override
public int getItemCount() {
return dataSet.size();
}
public void updateList(List<CustomModel> temp) {
dataSet = (ArrayList<CustomModel>) temp;
notifyDataSetChanged();
}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView rideHeight_textView;
public ViewHolder(View itemLayoutView) {
super(itemLayoutView);
rideHeight_textView = (TextView) itemLayoutView .findViewById(R.id.rideHeight_textView);
itemLayoutView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//action ****
}
});
}
}
}
Just call like
ArrayList<CustomModel> menuList = new ArrayList<>();
CustomModel c = new CustomModel();
c.setIt(1);
recyclerView.setHasFixedSize(true);
// ListView
recyclerView.setLayoutManager(new LinearLayoutManager(Your activity.this));
// create an Object for Adapter
MainAdapter mAdapter = new MainAdapter(menuList);
// set the adapter object to the Recyclerview
recyclerView.setAdapter(mAdapter);

recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setHasFixedSize(true);
LinearLayoutManager layoutManager = new LinearLayoutManager(context);
layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(layoutManager);
mAdapter = new MainAdapter(JsonData.rideList, MainActivity.this);
recyclerView.setAdapter(mAdapter);
mAdapter.notifyDataSetChanged();
adapter:

}
public class ViewHolder extends RecyclerView.ViewHolder {
public TextView rideHeight;
public ViewHolder(View itemView) {
super(itemView);

}
}
}

For starters you are not calling your data fetcher method in JsonData class. Your code is kind of messy so you can try the following solution:
In your adapter class add this method:
public void setList(ArrayList<Integer> rideList)
{
this.rideList = rideList;
notifyDataSetChanged();
}
Then in you JsonData class add:
private MainAdapter adapter;
public JsonData(MainAdapter adapter)
{
this.adapter = adapter;
dropHeight.set("");
rideCount.set("");
}
And change downloadFromSkistar to:
public void downloadFromSkistar()
{
if (SettingsActivity.submitClicked)
{
eID = SettingsActivity.x;
sID = SettingsActivity.y;
}
else
{
eID = 3206;
sID = 11;
}
new AsyncTask<Void, Void, List<Integer>>() {
#Override
protected List<Integer> doInBackground(Void... voids) {
try
{
URL url = new
URL("https://www.skistar.com/myskistar/api/v2/views/statisticspage.json?
entityId=" + eID + "&seasonId=" + sID + " ");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000 /* milliseconds */);
conn.setConnectTimeout(15000 /* milliseconds */);
conn.setRequestMethod("GET");
// Starts the query
conn.connect();
int response = conn.getResponseCode();
Log.i("AndroidExample", "Response: " + response);
if (response == 200)
{
String json = getJson(conn.getInputStream());
JSONObject jsonObject = new JSONObject(json);
JSONArray jsonArray = jsonObject.getJSONArray("rideStatistics");
int reponame = 0;
int rHeight = 0;
for (int i = 0; i < jsonArray.length(); i++)
{
JSONObject skiRun = jsonArray.getJSONObject(i);
reponame += skiRun.getInt("height");
rHeight += skiRun.getInt("height");
rideList.add(new Integer(rHeight));
rHeight = 0;
}
}
}
catch (Exception e)
{
Log.i("AndroidExample", "Error");
}
finally
{
}
return rideList;
}
#Override
protected void onPostExecute(List<Integer> list)
{
super.onPostExecute(list);
adapter.setList(rideList);
}
};
}
And in the end finally change MainActivity to:
public class MainActivity extends AppCompatActivity {
private ActivityMainViewModel viewmodel;
RecyclerView recyclerView;
MainAdapter mAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);
ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
viewmodel = new ActivityMainViewModel();
binding.setViewmodel(viewmodel);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
mAdapter = new MainAdapter(JsonData.rideList);
recyclerView.setAdapter(mAdapter);
new JsonData(mAdapter).downloadFromSkistar();
}
PS: You are going to get NetworkOnMainThread exception. So try to add the network code in AsyncTask

Here's what I did to solve it, and btw I'm also using the SwipeRefreshLayout.
public class MainActivity extends AppCompatActivity {
private ActivityMainViewModel viewmodel;
RecyclerView recyclerView;
MainAdapter mAdapter;
public static ArrayList<Integer> rideList = new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);
ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
viewmodel = new ActivityMainViewModel();
binding.setViewmodel(viewmodel);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
mAdapter = new MainAdapter(rideList);
recyclerView.setAdapter(mAdapter);
viewmodel.jdDownloadFromSkistar();
final SwipeRefreshLayout swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipelayout);;
swipeRefreshLayout.setColorSchemeResources(R.color.refresh,R.color.refresh1,R.color.refresh2);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
swipeRefreshLayout.setRefreshing(true);
refreshRecyclerView();
swipeRefreshLayout.setRefreshing(false);
}
});
}
private void refreshRecyclerView()
{
mAdapter.notifyDataSetChanged();
}
So what I did was make a call to the jdDownloadFromSkistar(); Method and when I swipe to refresh it updates the adapter by using the notifyDataSetChanged(); method.

RecyclerView with SearchView will not populate upon initialization

I am currently using searchView to filter results on a RecyclerView. The problem is when the fragment is initialized, the list won't appear not until I click on the search icon on the toolbar and type some texts on it. I've tried modifying the codes. Take a look specifically at the adapter and holder classes, if you'll try to exchange my current codes to these:
public MembershipActivationAdapter(Context context, List<Member> members){
this.context = context;
this.mMembers = members;
}
and
#Override
public MembershipActivationViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
final View itemView = LayoutInflater.from(context).inflate(R.layout.member_activation_content, viewGroup, false);
}
,it will show the list upon calling the fragment however if I'll type something on the SearchView, it seems to function only as a one way filter. It will filter names but whenever I'll try to remove a character or a text on the searchview, it won't show the list back. Please help me with this. These are my codes:
Adapter & ViewHolder class:
public class MembershipActivationAdapter extends RecyclerView.Adapter<MembershipActivationAdapter.MembershipActivationViewHolder> {
private final List<Member> mMembers;
private final LayoutInflater inflater;
//private final Context context;
public MembershipActivationAdapter(Context context, List<Member> members){
inflater = LayoutInflater.from(context);
mMembers = new ArrayList<>(members);
//this.context = context;
//this.mMembers = members;
}
#Override
public int getItemCount() {
return mMembers.size();
}
#Override
public void onBindViewHolder(MembershipActivationViewHolder holder, final int position) {
final Member m = mMembers.get(position);
holder.name.setText(m.getName());
holder.email.setText(m.getEmail());
if(m.getStatus().equals("Active")){
holder.status.setText(Html.fromHtml("<font color='#00CD00'>" + m.getStatus() + "</font>"));
}else{
holder.status.setText(Html.fromHtml("<font color='#ff0000'>" + m.getStatus() + "</font>"));
}
}
#Override
public MembershipActivationViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
final View itemView = inflater.inflate(R.layout.member_activation_content, viewGroup, false);
return new MembershipActivationViewHolder(itemView);
//final View itemView = LayoutInflater.from(context).inflate(R.layout.member_activation_content, viewGroup, false);
}

removeItem(i);
}
}
}
private void applyAndAnimateAdditions(List<Member> newMembers) {
for (int i = 0, count = newMembers.size(); i < count; i++) {
final Member member = newMembers.get(i);
if (!mMembers.contains(member)) {
addItem(i, member);
}
}
}
private void applyAndAnimateMovedItems(List<Member> newMembers) {

final int fromPosition = mMembers.indexOf(member);
if (fromPosition >= 0 && fromPosition != toPosition) {
moveItem(fromPosition, toPosition);
}
}
}
public Member removeItem(int position) {
final Member member = mMembers.remove(position);
notifyItemRemoved(position);
return member;
}
public void addItem(int position, Member member) {
mMembers.add(position, member);
notifyItemInserted(position);

public void moveItem(int fromPosition, int toPosition) {

}

Atlast! I was able to find the resolution for this. Kudos to the developer himself, Xaver Kapeller!
public void populate(){
JsonArrayRequest request = new JsonArrayRequest(url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray jsonArray) {
// hidePDialog();
String email, status;
// Member member;
for(int i = 0; i < jsonArray.length(); i++) {
try {
JSONObject object = jsonArray.getJSONObject(i);
final String name = object.getString("firstname") + " " + object.getString("lastname");
email = object.getString("email");
if(Integer.parseInt(object.getString("activated"))==1){

}else{

}
mModels.add(new ExampleModel(name));
// member = new Member(name, email, status);
} catch (Exception e) {

mRecyclerView.setAdapter(mAdapter);
}
}, new Response.ErrorListener(){
#Override
public void onErrorResponse(VolleyError volleyError) {

});
AppController.getInstance().addToRequestQueue(request);

Just tranfer these two lines of code inside onResponse() and everything will work perfectly fine:
mAdapter = new ExampleAdapter(getActivity(), mModels);
mRecyclerView.setAdapter(mAdapter);
