Please I would like someone to help point me in the right direction with using the ParseRecyclerQueryAdapter. I'm trying to retrieve articles with my current adapter class that implements the standard RecyclerView. my implementation of pagination is not working properly soIi would like a demonstration from anyone that has used the ParseRecyclerQueryAdapter to achieve the following. By translating it from me so I get the implementation.
public class ArticleRVAdapter extends RecyclerView.Adapter {
List<Article> articleData = Collections.emptyList();
private LayoutInflater inflater;
private Context context;
public ArticleRVAdapter(Context context, List<Article> data){
inflater=LayoutInflater.from(context);
this.articleData= data;
this.context = context;
}
#Override
public ArticleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = inflater.inflate(R.layout.article_item, parent, false);
ArticleViewHolder viewHolder = new ArticleViewHolder(view);
return viewHolder;
}
#Override
public int getItemCount() {
return articleData.size();
}
public class ArticleViewHolder extends RecyclerView.ViewHolder
implements View.OnClickListener {
CardView cardView;
TextView title;
TextView body;
Date dateCreated;
TextView author;
ImageView headImage;
String objectId;
public ArticleViewHolder(final View itemView) {
super(itemView);
itemView.setClickable(true);
itemView.setLongClickable(true);
itemView.setOnClickListener(this);
cardView = (CardView) itemView.findViewById(R.id.card_article);
title = (TextView) itemView.findViewById(R.id.text_title);
body = (TextView) itemView.findViewById(R.id.text_article_body);
//dateCreated = itemView.findViewById(R.id.text_article_body);
author = (TextView) itemView.findViewById(R.id.text_author);
headImage = (ImageView) itemView.findViewById(R.id.imageView_thumb);
}
#Override
public void onClick(View v) {
Intent intent = new Intent(v.getContext(), ArticleInformationActivity.class);
intent.putExtra("article_id", articleData.get(getLayoutPosition()).getObjectId());
intent.putExtra("article_title", articleData.get(getLayoutPosition()).getArticleTitle());
intent.putExtra("article_body", articleData.get(getLayoutPosition()).getArticleBody());
intent.putExtra("article_author", articleData.get(getLayoutPosition()).getArticleAuthor());
intent.putExtra("article_date", articleData.get(getLayoutPosition()).getDateCreated());
v.getContext().startActivity(intent);
}
}
After a lot of testing, I got the solution in my project:
Fragment (or Activity):
private RecyclerView mRecyclerView;
private MyQueryAdapter myQueryAdapter;
private SwipeRefreshLayout swipeRefreshLayout;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.list_fragment, container, false);
mRecyclerView = (RecyclerView) view.findViewById(R.id.rv);
myQueryAdapter = new MyQueryAdapter(true);
mRecyclerView.setAdapter(myQueryAdapter);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
myQueryAdapter.addOnQueryLoadListener(new ParseRecyclerQueryAdapter.OnQueryLoadListener<MY_MODEL>() {
#Override
public void onLoaded(List<MY_MODEL> objects, Exception e) {
if (swipeRefreshLayout.isRefreshing()) {
swipeRefreshLayout.setRefreshing(false);
}
}
#Override
public void onLoading() {
if (!swipeRefreshLayout.isRefreshing()) {
swipeRefreshLayout.setRefreshing(true);
}
}
});
swipeRefreshLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_container);
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
myQueryAdapter.loadObjects();
}
});
return view;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
#Override
public void onResume() {
super.onResume();
myQueryAdapter.loadObjects();
}
Adapter
public class MyQueryAdapter extends ParseRecyclerQueryAdapter<MY_MODEL, MyQueryAdapter.MyViewHolder>{
public MyQueryAdapter(boolean hasStableIds) {
super(MY_MODEL.class, hasStableIds);
}
public MarcacionesAdapter(ParseQueryAdapter.QueryFactory<Marcaciones> factory, boolean hasStableIds) {
super(factory, hasStableIds);
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.cardview, parent, false);
MyViewHolder myViewHolder = new MyViewHolder(v);
return myViewHolder;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
MY_MODEL model = getItem(position);
holder.name.setText(model.getName());
holder.year.setText(model.getYear());
}
public static class MyViewHolder extends RecyclerView.ViewHolder {
CardView cv;
TextView name;
TextView year;
MyViewHolder(View itemView) {
super(itemView);
cv = (CardView)itemView.findViewById(R.id.card_view);
name = (TextView)itemView.findViewById(R.id.name);
year = (TextView)itemView.findViewById(R.id.year);
}
}
}
If you want to configure a custom query, you can do it in this way:
factory =
new ParseQueryAdapter.QueryFactory<MY_MODEL>() {
public ParseQuery< MY_MODEL > create() {
ParseQuery<MY_MODEL> query = MY_MODEL.getQuery();
query.include("user");
//Filter by date
query.whereGreaterThan("createdAt", midnight);
query.whereLessThan("createdAt", now);
query.orderByDescending("createdAt");
return query;
}
};
adapter = new MyQueryAdapter(factory, true);

I have a problem in my code, I want to send the data I clicked from the RecyclerView to edit text in the same activity
My adapter:
public class RecyclerViewAdapter1 extends RecyclerView.Adapter<RecyclerViewAdapter1.ViewHolder> {
private Context context;
private List<Result> results;
public RecyclerViewAdapter1(Context context, List<Result> results) {
this.context = context;
this.results = results;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.arraylist1, parent,false);
ViewHolder holder = new ViewHolder(v);
return holder;
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Result result = results.get(position);
holder.textViewid.setText(result.getRef_desa_id());
holder.textViewNm_desa.setText(result.getNama_desa());
}
#Override
public int getItemCount() {
return results.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
#BindView(R.id.txtid)
TextView textViewid;
#BindView(R.id.txtnm_desa)
TextView textViewNm_desa;
public ViewHolder(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
}
#Override
public void onClick(View v) {
String id = textViewid.getText().toString();
Intent i = new Intent(context, DaftarDukaActivity2.class);
((Activity)context).finish();
i.putExtra("id", id);
context.startActivity(i);
}
}
}
In the code above, my coding has succeeded in displaying data to another Edit text activity. I want to ask, how to send data from the RecyclerView I clicked to EditText in the same activity?
Do you want editText.setText() from reacyclerview adapter? You can do like this:
public class RecyclerViewAdapter1 extends RecyclerView.Adapter<RecyclerViewAdapter1.ViewHolder> {
private Context context;
private List<Result> results;
private EditText editText;
public RecyclerViewAdapter1(Context context, List<Result> results,EditText editText) {
this.context = context;
this.results = results;
this.editText=editText;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.arraylist1, parent,false);
ViewHolder holder = new ViewHolder(v);
return holder;
}
#Override
public void onBindViewHolder(ViewHolder holder, int position) {
Result result = results.get(position);
holder.textViewid.setText(result.getRef_desa_id());
holder.textViewNm_desa.setText(result.getNama_desa());
}
#Override
public int getItemCount() {
return results.size();
}
public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
#BindView(R.id.txtid)
TextView textViewid;
#BindView(R.id.txtnm_desa)
TextView textViewNm_desa;
public ViewHolder(View itemView) {
super(itemView);
ButterKnife.bind(this, itemView);
}
#Override
public void onClick(View v) {
String id = textViewid.getText().toString();
editText.setText(id);
}
}
}
Usage
public class MainActivity extends AppCompatActivity{
private Context context=this;
private List<Result> results;
private EditText editText;
private RecyclerView rec;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText=findViewById(R.id.my_edit_text_id_in_xml);
rec=findViewById(R.id.my_recycler_view_id);
// add items to your result List
rec.setAdapter(new RecyclerViewAdapter1(context,results,editText));
rec.setLayoutManager(new LinearLayoutManager(context));
}
}
Im working on a news reader app that uses fragments. I get my data from the newsapi. So far I have managed to pull the data from the api and display it in a recyclerview but when I click on an item, nothing happens!

It seems all you are doing inside your onClick is getting the item position. It is now up to you to do something with that position.
So the question comes down to, what do you want to do?
Launch a details activity/fragment to display more info? That is a typical pattern for mobile.
Intent i = new Intent(context,DetailActivity.class);
i.putExtra(Your Data);
startActivity(i);
I'm trying to add a recyclerview to a fragment, but somehow there happens to be an error in the adapter.
I think it is the way in which I bind it, and I can't figure out the solution to it. Can anybody help me solve the issue?
here's my adapter:

from what I've read, the issue is with the way I bind the recylerview but I've not got a clear idea about where the issue actually lies.
It is possible that one or many of your listItem attributes return an integer like getScore and getFee. So let's look at the implementation of TextView.setText(int)
public final void setText(int resid) {
...
}
As you can see, it only accepts the int as a resource id like R.string.something.
So what you can do here is to make your int become string when setText like
holder.playerPoints.setText(listItem.getScore().toString());
i want to put setOnClickListener on the recyclerview that i follow on a tutorial, the problem is, i don't know where to put it, i got mixed with all other features of the app, i believe the code must be put somewhere here :
this is my ExampleAdapter :
public class ExampleAdapter extends RecyclerView.Adapter<ExampleAdapter.ExampleViewHolder>{
private ArrayList<ExampleItem> mExampleList;
public static class ExampleViewHolder extends RecyclerView.ViewHolder {
public ImageView mImageView;
public TextView mTextView1;
public TextView mTextView2;
public ExampleViewHolder(View itemView) {
super(itemView);
mImageView = itemView.findViewById(R.id.imageView);
mTextView1 = itemView.findViewById(R.id.textView);
mTextView2 = itemView.findViewById(R.id.textView2);
}
}
public ExampleAdapter(ArrayList<ExampleItem> exampleList) {
mExampleList = exampleList;
}
#Override
public ExampleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.example_item,
parent, false);
ExampleViewHolder evh = new ExampleViewHolder(v);
return evh;
}
#Override
public void onBindViewHolder(ExampleViewHolder holder, int position) {
ExampleItem currentItem = mExampleList.get(position);
holder.mImageView.setImageResource(currentItem.getImageResource());
holder.mTextView1.setText(currentItem.getText1());
holder.mTextView2.setText(currentItem.getText2());
}
#Override
public int getItemCount() {
return mExampleList.size();
}
public void filterList(ArrayList<ExampleItem> filteredList) {
mExampleList = filteredList;
notifyDataSetChanged();
}
}
really appreciate you guys, if you could help me.
Use this in your activity in which you have recyclerview
rv= (RecyclerView) findViewById(R.id.rv);
rv.setLayoutManager(new LinearLayoutManager(this));
rv.addOnItemTouchListener(
new RecyclerItemClickListener(this, rv ,new RecyclerItemClickListener.OnItemClickListener() {
#Override public void onItemClick(View view, int position) {
// do whatever
}
#Override public void onLongItemClick(View view, int position) {
// do whatever
}
})
);
Just edit extends RecyclerView.ViewHolder implements View.OnClickListener
and implement OnClick method ,edit as public ExampleViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
#Override
public void onClick(View v) {
}
So im having this issue in my adapter to were when i go to set the Picasso method to convert my image url it will not allow me to pass the context no matter how i do it. i Have tried this and The class name .this neither seem to work. Not sure what or why this is happening. Here is the adapter class that im having issues with.
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ContentViewHolder> {
public content[] mDataset;
public MyAdapter(content[] data) {
mDataset = data;
}
#Override
public ContentViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.test, parent, false);
ContentViewHolder viewHolder = new ContentViewHolder(view);
return viewHolder;
}
#Override
public void onBindViewHolder(ContentViewHolder holder, int position) {
holder.bindContent(mDataset[position]);
}
#Override
public int getItemCount() {
return mDataset.length;
}
public class ContentViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public TextView mUrl;
public TextView mTitle;
public TextView mDate;
public TextView mAuthor;
public ImageView mThumbnail;
public ContentViewHolder(View itemView) {
super(itemView);
mUrl= (TextView) itemView.findViewById(R.id.url);
mTitle = (TextView) itemView.findViewById(R.id.title);
mDate = (TextView) itemView.findViewById(R.id.date);
mAuthor = (TextView) itemView.findViewById(R.id.author);
mThumbnail =(ImageView)itemView.findViewById(R.id.thumbnail);
}
public void bindContent(content bloginfo) {
mUrl.setText(bloginfo.getUrl());
mTitle.setText(bloginfo.getTitle());
mDate.setText(bloginfo.getDate());
mAuthor.setText(bloginfo.getAuthor());
Picasso.with(context).load(bloginfo.getThumbnail()).into(mThumbnail);
}
#Override
public void onClick(View view) {
}
}
}
Ok so i got this to work here is the working adapter code below. Thank you all for your help.
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ContentViewHolder> {
public content[] mDataset;
private Activity activityContext;
public MyAdapter(Activity context,content[] data) {
mDataset = data;
activityContext = context;
}
#Override
public ContentViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.test, parent, false);
ContentViewHolder viewHolder = new ContentViewHolder(view);
return viewHolder;
}
#Override
public void onBindViewHolder(ContentViewHolder holder, int position) {
holder.bindContent(mDataset[position]);
}
#Override
public int getItemCount() {
return mDataset.length;
}
public class ContentViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
public TextView mUrl;
public TextView mTitle;
public TextView mDate;
public TextView mAuthor;
public ImageView mThumbnail;
public ContentViewHolder(View itemView) {
super(itemView);
mUrl= (TextView) itemView.findViewById(R.id.url);
mTitle = (TextView) itemView.findViewById(R.id.title);
mDate = (TextView) itemView.findViewById(R.id.date);
mAuthor = (TextView) itemView.findViewById(R.id.author);
mThumbnail =(ImageView)itemView.findViewById(R.id.thumbnail);
}
public void bindContent(content bloginfo) {
mUrl.setText(bloginfo.getUrl());
mTitle.setText(bloginfo.getTitle());
mDate.setText(bloginfo.getDate());
mAuthor.setText(bloginfo.getAuthor());
Picasso.with(activityContext).load(bloginfo.getThumbnail()).into(mThumbnail);
}
#Override
public void onClick(View view) {
}
}
}
This
Picasso.with(MyAdapter.this)
should be
Picasso.with(context)
Use Activity Context. This can be passed to the constructor of adapter class from activity.
http://developer.android.com/reference/android/content/Context.html
http://square.github.io/picasso/
Samples available on github
https://github.com/square/picasso/blob/master/picasso-sample/src/main/java/com/example/picasso/PicassoSampleAdapter.java
In your adapter you can make:
private Activity activityContext;
then in Adapter contructor:
public MyAdapter(Activity context, content[] data) {
mDataset = data;
activityContext = context;
}
Finally call:
Picasso.with(activityContext).load(bloginfo.getThumbnail()).into(mThumbnail);
If you create your Adapter in your Activity you need to create it using:
new myAdapter(this, YOURDATA), if you create it in Fragment, you need to use new myAdapter(getActivity(), YOURDATA).
Picasso.with(mThumbnail.getContext()).load(bloginfo.getThumbnail()).into(mThumbnail);
