Error with RecyclerView: No adapter attached; skipping layout

I can't get my code work
I'm trying to get a list of my database activities.
A lot of research here and none of the answers helped me
My Adapter
public class AtividadesAdapter extends RecyclerView.Adapter<AtividadesAdapter.AtividadesViewHolder> {
private Context mCtx;
private List<Atividades> atividadesList;
public AtividadesAdapter(Context mCtx, List<Atividades> atividadesList) {
this.mCtx = mCtx;
this.atividadesList = atividadesList;
}
#Override
public AtividadesViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
LayoutInflater inflater = LayoutInflater.from(mCtx);
View view = inflater.inflate(R.layout.atividades_lista, null);
return new AtividadesViewHolder(view);
}
#Override
public void onBindViewHolder(AtividadesViewHolder holder, int position) {
Atividades atividades = atividadesList.get(position);
holder.textViewAtividade.setText(atividades.getAtividade());
holder.textViewData.setText(String.valueOf(atividades.getDataPrevista()));
holder.textViewHora.setText(String.valueOf(atividades.getHora()));
holder.textViewDestinatarios.setText(atividades.getDestinatarios());
}
#Override
public int getItemCount() {
return atividadesList.size();
}
class AtividadesViewHolder extends RecyclerView.ViewHolder {
TextView textViewAtividade, textViewData, textViewHora, textViewDestinatarios;
public AtividadesViewHolder(View itemView) {
super(itemView);
textViewAtividade = itemView.findViewById(R.id.textViewAtividade);
textViewData = itemView.findViewById(R.id.textViewData);
textViewHora = itemView.findViewById(R.id.textViewHora);
textViewDestinatarios = itemView.findViewById(R.id.textViewDestinatarios);
}
}
}
My activity
public class AtividadesActivity extends AppCompatActivity {
private static final String URL_ATIVIDADES = "";
List<Atividades> atividadesList = new ArrayList<>();
public RecyclerView recyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.atividadesrecyclerview);
recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
loadAtividades();
}
private void loadAtividades() {
StringRequest stringRequest = new StringRequest(Request.Method.GET, URL_ATIVIDADES,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONArray array = new JSONArray(response);
for (int i = 0; i < array.length(); i++) {
JSONObject a = array.getJSONObject(i);
Log.d("Valores", a.getString("Atividade"));
atividadesList.add(new Atividades(
a.getInt("idAtividade"),
a.getString("Atividade"),
java.sql.Date.valueOf(a.getString("dataPrevista")),
java.sql.Time.valueOf(a.getString("hora")),
a.getString("Destinatarios"),
a.getString("Local")
));
}
AtividadesAdapter mAdapter = new AtividadesAdapter(AtividadesActivity.this, atividadesList);
recyclerView.setAdapter(mAdapter);
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
Volley.newRequestQueue(this).add(stringRequest);
}
}
Everytime i'm trying to start the app, i get this error.
I have already change the xml files to match with the examples provided here but still have no success.

Please attach parent and the rest:
#Override
public Holder onCreateViewHolder(ViewGroup parent, int viewType) {
return new AtividadesViewHolder(LayoutInflater.from(mCtx).inflate(R.layout.atividades_lista, parent, false));
}

Based on your question and the code I think this will help you.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.atividadesrecyclerview);
recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
AtividadesAdapter mAdapter = new AtividadesAdapter(getApplicationContext, atividadesList);
recyclerView.setAdapter(mAdapter);
loadAtividades();
}

Add to your adapter:
public AtividadesAdapter(Context mCtx) {
this.mCtx = mCtx;
}
public void setItems(#NonNull final List<Atividades> items) {
if (atividadesList != null) {
atividadesList.clear();
} else {
atividadesList = new ArrayList<>();
}
atividadesList.addAll(items);
}
onCreate of the activity should be as follows:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.atividadesrecyclerview);
recyclerView = findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setHasFixedSize(true);
mAdapter = new AtividadesAdapter(AtividadesActivity.this);
recyclerView.setAdapter(mAdapter);
loadAtividades();
}
In loadAtividades() call to setItems:
mAdapter.setItems(atividadesList);

Getting empty RecyclerVew item sometimes despite calling adapterlist.clear()

I'm trying to show the details of students in a recyclerview, obtained from a web service. The app works in a way that in an Activity, it opens list of students and then on touch of a student, it opens another activity which will show the details of that particular student in a recyclerview.
Problem:
I sometimes get an empty recyclerview item either above or below the valid item with data. I tried calling StuDetailsDataAdapterClassList.clear(); but it doesn't fix the issue. Some times it works fine but I don't understand why it is happening. Your help is valuable for me.

android - recyclerview cannot click and get position

I have tried some code to can click recyclerview item and get position, but I can't click the recyclerview item.. the data I get from url. So I wan't switch activity with get the item user click..
how I can fix that?
this code for adapter
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
Context context;
private static final String TAG = RecyclerViewAdapter.class.getSimpleName();
List<GetDataAdapter> getDataAdapter;
ImageLoader imageLoader1;
public RecyclerViewAdapter(List<GetDataAdapter> getDataAdapter, Context context) {
super();
this.getDataAdapter = getDataAdapter;
this.context = context;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recyclerview_items, parent, false);
ViewHolder viewHolder = new ViewHolder(v);
return viewHolder;
}
#Override
public void onBindViewHolder(ViewHolder Viewholder, int position) {
GetDataAdapter getDataAdapter1 = getDataAdapter.get(position);
imageLoader1 = ServerImageParseAdapter.getInstance(context).getImageLoader();
imageLoader1.get(getDataAdapter1.getImageServerUrl(),
ImageLoader.getImageListener(
Viewholder.networkImageView,//Server Image
R.mipmap.ic_launcher,//Before loading server image the default showing image.
android.R.drawable.ic_dialog_alert //Error image if requested image dose not found on server.
)
);
Viewholder.networkImageView.setImageUrl(getDataAdapter1.getImageServerUrl(), imageLoader1);
Viewholder.ImageTitleNameView.setText(getDataAdapter1.getImageTitleName());
}
#Override
public int getItemCount() {
return getDataAdapter.size();
}
class ViewHolder extends RecyclerView.ViewHolder{

super(itemView);
ImageTitleNameView = (TextView) itemView.findViewById(R.id.textView_item);
networkImageView = (NetworkImageView) itemView.findViewById(R.id.VollyNetworkImageView1);
}
}
}
and this code for mainactivity
public class MainActivity extends AppCompatActivity {
List<GetDataAdapter> GetDataAdapter1;

You need to set onClickListener to your item view. You can do by following below steps:
Set onCLickListener to root view of your list item.
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.recyclerview_items, parent, false);
Add below code in onCreateViewHolder:
v.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Add your logic here
}
});
You can add listener while onBindViewHolder:
holder.itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Add your logic here
}
});
Thanks.

Put a listener on your recycler item view and then in onclick, start intent to open new activity. Pass the data object you want to pass with the intent.
//make sure your model class GetDataAdapter implements Parcelable
holder.itemView.setOnclickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(this, ActivityToOpen.class);
intent.putExtra("key",Your Object to pass);// getDataAdapter1 in your case
context.startActivity(intent);
}
});
then in your Startted activity receive your object like this
YourObject obj = getIntent().getParcelableExtra("key");
//Your case
GetDataAdapter obj = getIntent().getParcelableExtra("key");

Android Recycler View

I am using RecyclerView to display my products, problem is when if I select the first products and scroll down to the end of list I see different products selected and when i scroll back to top of list the first item is not selected.
My Adapter
public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerAdapter.MyViewHolder> {
String u = "http://192.185.52.231/~sabby070/hyype/";

Imagelike = (ImageView)view.findViewById(R.id.Like_Button);
ImageUnlike = (ImageView)view.findViewById(R.id.UnLike_Button);
}
}
#Override
public void onBindViewHolder(final RecyclerAdapter.MyViewHolder holder, final int position) {
final ProductDetails detail = List.get(position);
holder.Likecount.setText(detail.getLikeCount());
Glide.with(context1).load(u+detail.getImage()).override(600, 200).diskCacheStrategy(DiskCacheStrategy.ALL).into(holder.Image);
holder.Image.setOnClickListener(new View.OnClickListener() {

Map<String, String> params = new HashMap<String, String>();
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
requestQueue.add(stringRequest);
return view;
}
}

You have to take List(with boolean) and store selected values in that list and then use those values in onBindView()

In your ProductDetails class add a field boolean selected;
In your onClick() add List.get(position).setSelected(!List.get(position).isSelected()); to check/uncheck as needed.
Finaly in your onBindViewHolder(...) add
if(List.get(position).isSelected()){
holder.Imagelike.setVisibility(View.VISIBLE);
}else{
holder.ImageUnlike.setVisibility(View.GONE);
}

help me

First of all, Check in adapter. Are you getting url is image or video. If url is contain image then need to check in ImageLoader Library. you can better use with glide and picasso.
Its very easy to use picasso. You can found picasso from this link
http://square.github.io/picasso/
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);
If your url contain video then you have to create thumbnail from url using Thumnail Util
Bitmap thumb = ThumbnailUtils.createVideoThumbnail(filePath,
Thumbnails.MINI_KIND); imageview.setBitmapImage(thumb);
