that is RecyclerView xml.

</RelativeLayout>
That is RecyclerView adpater class file
public class ArtistAdapter extends RecyclerView.Adapter<ArtistAdapter.Holder> {
ArrayList<ArtistPojo> artistPojos;
Context context;
LayoutInflater inflater;
View v;
public ArtistAdapter(Context c, ArrayList<ArtistPojo> pojos) {
context = c;
artistPojos = pojos;
}
#Override
public Holder onCreateViewHolder(ViewGroup parent, int viewType) {
//inflate layout
inflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
View v = inflater.inflate(R.layout.activity_artist_adapter, null);
return new ArtistAdapter.Holder(v);
}
#Override
public int getItemCount() {
return artistPojos.size();
}
#Override
public void onBindViewHolder(Holder holder, int position) {
final ArtistPojo artistPojo = artistPojos.get(position);
holder.artist.setText(artistPojo.getArtist());
holder.artist_img.setImageResource(R.drawable.splash);
}
public static class Holder extends RecyclerView.ViewHolder {
TextView artist;
ImageView artist_img, dot;
CardView Artist;
public Holder(View itemView) {
super(itemView);
//find by id to adpater file
artist = itemView.findViewById(R.id.artist_txttitile);
artist_img = itemView.findViewById(R.id.artist_img);
Artist = itemView.findViewById(R.id.card_view);
dot = itemView.findViewById(R.id.overflow);
}
}
}
And There is RecyclerView xml adpater file.
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>

That is my ArtistPojo class
public class ArtistPojo {
Long Media_Id;
String Artist, ArtistId, Song;
public ArtistPojo(Long media_Id, String artist, String artistId, String song) {
Media_Id = media_Id;
Artist = artist;
ArtistId = artistId;
Song = song;
}
public Long getMedia_Id() {
return Media_Id;
}
public void setMedia_Id(Long media_Id) {
Media_Id = media_Id;
}
public String getArtist() {
return Artist;
}
public void setArtist(String artist) {
Artist = artist;
}
public String getArtistId() {
return ArtistId;
}
public void setArtistId(String artistId) {
ArtistId = artistId;
}
public String getSong() {
return Song;
}
public void setSong(String song) {
Song = song;
}
}

You are not adding any item in artistPojos ArrayList check it
add data in your arraylist like this
do {
String Media_id = musicCursor.getString(media_id);
String artistId = musicCursor.getString(artistid);
String artistName = musicCursor.getString(artistname);
ArtistPojo pojo= new ArtistPojo();
pojo.setData("");// as per your getter and setter method here
artistPojos.add(pojo)
Log.d("mediaid", "" + Media_id);
Log.d("artistid", "" + artistId);
Log.d("artistname", "" + artistName);
} while (musicCursor.moveToNext());
And also change this make your activity_artist_adapter hight android:layout_height="wrap_content"
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="#+id/reclerview_adpater"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginTop="20dp">

First, you need to get the view from the XML
ImageView imageView = view.findViewById(R.id.name);
Then you need to set the data and imageview in Picasso like
Picasso.get()
.load(getApiUrl + "/upload/category/" + mensWears.get(i).category_image())
.placeholder(R.drawable.ic_thumbnail)
.into(imageView);

RecyclerView shows Strings but not Images

I have a SQLite database and want to search Items thorugh DB and then showing the items on recyclerView. Everything looking fine but recyclerView not showing the pictures, But somehow It shows the Strings
Normally pictures I saved inside the SQLite as BLOB should be displayed on the left.
Here is SearchFragment (Where I make the search and start recyclerView to display items)
public class SearchFragment extends Fragment {
Button searchbutton;
EditText editText;
View v;
Cursor cursor;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
v = inflater.inflate(R.layout.fragment_search, container, false);
addListenerOnButton(v);
return v;
}
private void addListenerOnButton(View v) {
searchbutton = v.findViewById(R.id.searchfragment_button);
editText = v.findViewById(R.id.searchfragment_edittext);
searchbutton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String keystring = editText.getText().toString();
if(keystring.isEmpty())
Toast.makeText(getContext(),R.string.empty_search ,Toast.LENGTH_LONG).show();
else
new FoodQuery().execute(keystring);
}
});
}
//Place I start the search on background
private class FoodQuery extends AsyncTask<String, Void, Void>{
#Override
protected Void doInBackground(String [] keys) {
String name_col;
DietAppDatabaseHelper daDBHelper;
SQLiteDatabase daDB;
daDBHelper = new DietAppDatabaseHelper(getContext());
try {
daDB = daDBHelper.getReadableDatabase();
if (Locale.getDefault().getLanguage() == "tr")
name_col = "name_tr";
else
name_col = "name_eng";
String query = "SELECT * FROM food_data WHERE " //Query here
+ name_col + " LIKE ?" ;
cursor = daDB.rawQuery(query, new String[]{"%" + keys[0] + "%"});
viewResults(name_col);
daDB.close();
} catch (SQLiteException e){
Log.d("SearchFragment", "doInBackground: " + e);
}
return null;
}
}
private void viewResults(String lang) {
int name_col = -1; //For language issues not important
if(lang == "name_tr")
name_col = 1;
else if(lang == "name_eng")
name_col = 2;
ArrayList<String> tmpnames = new ArrayList<>(); //I put pictures to byte[] and names to String Arraylist here
ArrayList<byte[]> tmppictures = new ArrayList<>();
if(cursor.moveToFirst()){
tmpnames.add(cursor.getString(name_col));
tmppictures.add(cursor.getBlob(5));
while(cursor.moveToNext()){
tmpnames.add(cursor.getString(name_col));
tmppictures.add(cursor.getBlob(5));
}
}
else {
Looper.prepare();
Toast.makeText(getContext(), R.string.no_food_found, Toast.LENGTH_LONG).show(); //To prevent empty search
}
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
RecyclerView recyclerView = v.findViewById(R.id.recycler_view);
SearchResultAdapter adapter = new SearchResultAdapter(getContext(), tmppictures, tmpnames);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false));
recyclerView.setAdapter(adapter);
}
});
}
}

Here is the adapter
public class SearchResultAdapter extends RecyclerView.Adapter<SearchResultAdapter.ViewHolder>{
private ArrayList<byte[]> foodimages;
private ArrayList<String> foodnames;
private Context context;
public SearchResultAdapter(Context context, ArrayList<byte[]> foodimages, ArrayList<String> foodnames) {
this.foodimages = new ArrayList<>(foodimages);
this.foodnames = new ArrayList<>(foodnames);
this.context = context;
}
#NonNull
#Override
public ViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.search_result_item, parent, false);
ViewHolder holder = new ViewHolder(view);
return holder;
}
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, int position) {
holder.foodname.setText(foodnames.get(position));
holder.foodimage.setImageBitmap(BitmapFactory.decodeByteArray(foodimages.get(position), 0, foodimages.size()));
}
#Override
public int getItemCount() {
return foodnames.size();
}
public class ViewHolder extends RecyclerView.ViewHolder{
ImageView foodimage;
TextView foodname;
RelativeLayout parentLayout;
public ViewHolder(#NonNull View itemView) {
super(itemView);
foodimage = itemView.findViewById(R.id.food_seacrh_image);
foodname = itemView.findViewById(R.id.food_search_name);
parentLayout = itemView.findViewById(R.id.search_item);
}
}
}
Lastly, the layout of my item to use in recyclerView
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="15dp"
android:id="#+id/search_item">
<ImageView
android:id="#+id/food_seacrh_image"
android:layout_width="100dp"
android:layout_height="100dp"
/>
<TextView
android:id="#+id/food_search_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/food_seacrh_image"
android:textColor="#FFFFFF"
android:layout_centerVertical="true"
android:layout_marginLeft="30dp"
android:textSize="17sp"
android:layout_toEndOf="#+id/food_seacrh_image"
android:layout_marginStart="30dp" />

It seems like the problem could be the line:
holder.foodimage.setImageBitmap(BitmapFactory.decodeByteArray(foodimages.get(position), 0, foodimages.size()));
Should probably be:
holder.foodimage.setImageBitmap(BitmapFactory.decodeByteArray(foodimages.get(position), 0, foodimages.get(position).size));
The third param on decodeByteArray should be the length (in bytes) of the image, you are passing in the actual number of images.

How to update imageview from the parent recyclerview after click on nested recyclerview's imageview

Please check following screenshot, I want to update imageview from parent recyclerview when user click on imageview from nested recyclerview.
I have taken two individual adapters for for parent & nested recyclerview.I am not able to do the functionality for updating image, kindly help.
Parent Recyclerview Adapter:
public class RecyclerViewDataAdapter extends RecyclerView.Adapter<RecyclerViewDataAdapter.ItemRowHolder> {
private ArrayList<PLDModel> dataList;
private Context mContext;
public RecyclerViewDataAdapter(Context context, ArrayList<PLDModel> dataList) {
this.dataList = dataList;
this.mContext = context;
}
#Override
public ItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item_card_view, null);
ItemRowHolder mh = new ItemRowHolder(v);
return mh;
}
#Override
public void onBindViewHolder(ItemRowHolder itemRowHolder, int i) {
final String itemTitle = dataList.get(i).getTitle();
final String itemDescription = dataList.get(i).getDescription();
ArrayList<SmallImages> singleSectionItems = dataList.get(i).getSmallImages();
itemRowHolder.itemTitle.setText(Html.fromHtml("<b>" + itemTitle + " </b> " + itemDescription));
SectionListDataAdapter itemListDataAdapter = new SectionListDataAdapter(mContext, singleSectionItems);
itemRowHolder.recyclerSmallImageList.setHasFixedSize(true);
itemRowHolder.recyclerSmallImageList.setLayoutManager(new LinearLayoutManager(mContext, LinearLayoutManager.HORIZONTAL, false));
itemRowHolder.recyclerSmallImageList.setAdapter(itemListDataAdapter);
}
#Override
public int getItemCount() {
return (null != dataList ? dataList.size() : 0);
}
public class ItemRowHolder extends RecyclerView.ViewHolder {
protected TextView itemTitle, expandImage;
protected ImageView bookmarkImage,largeImage;
protected RecyclerView recyclerSmallImageList;
protected Button btnMore;
public ItemRowHolder(View view) {
super(view);
this.itemTitle = (TextView) view.findViewById(R.id.title);
this.bookmarkImage = (ImageView) view.findViewById(R.id.bookmark);
this.largeImage = (ImageView) view.findViewById(R.id.large_image);
this.expandImage = (TextView) view.findViewById(R.id.expand);
this.recyclerSmallImageList = (RecyclerView) view.findViewById(R.id.recycler_small_image_list);
}
}
}
Nested Recyclerview Adapter:
public class SectionListDataAdapter extends RecyclerView.Adapter<SectionListDataAdapter.SingleItemRowHolder> {
private ArrayList<SmallImages> itemsList;
private Context mContext;
public SectionListDataAdapter(Context context, ArrayList<SmallImages> itemsList) {
this.itemsList = itemsList;
this.mContext = context;
}
#Override
public SingleItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.small_images_view, null);
SingleItemRowHolder mh = new SingleItemRowHolder(v);
return mh;
}
#Override
public void onBindViewHolder(SingleItemRowHolder holder, int i) {
SmallImages singleItem = itemsList.get(i);
}
#Override
public int getItemCount() {
return (null != itemsList ? itemsList.size() : 0);
}
public class SingleItemRowHolder extends RecyclerView.ViewHolder {
protected ImageView itemImage;
public SingleItemRowHolder(View view) {
super(view);
//this.tvTitle = (TextView) view.findViewById(R.id.tvTitle);
this.itemImage = (ImageView) view.findViewById(R.id.item_small_image);
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Toast.makeText(v.getContext(), tvTitle.getText(), Toast.LENGTH_SHORT).show();
}
});
}
}
}

Using two Recyclerview will be hard to control rather than use a Single adapter and control everything from there.I have just worked on this type of thing that's why I am posting my code there may be some unwanted code which u may need.
/////Adapter class

Generally, the solution is to pass custom interface listener into the nested adapter and than the nested adapter will report any time one of his item clicked.
1.
You can create interface like:
public interface INestedClicked {
onNestedItemClicked(Drawable drawble)
}
2.
Pass in the constructor of SectionListDataAdapter a INestedClicked:
SectionListDataAdapter itemListDataAdapter = newSectionListDataAdapter(mContext, singleSectionItems, new INestedClicked() {
#Override
void onNestedItemClicked(Drawable drawble) {
// Do whatever you need after the click, you get the drawable here
}
});
In the constructor of SectionListDataAdapter save the instance of the listener as adapter parameter
private INestedClicked listener;
4.
When nested item clicked report the listener:
view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(listener != null){
listener.onNestedItemClicked(imageView.getDrawable());
}
}

ListView leaves extra space below and above of the list

I have dynamic list of several name. But ListView leaves extra space below and above of the total list item.
At routes_recycler_listview.xml, Here, I have use this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"

</RelativeLayout>
<com.github.aakira.expandablelayout.ExpandableRelativeLayout
android:id="#+id/expandableLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/header"
android:background="#drawable/recycler_item_bg"
app:ael_duration="400"
app:ael_expanded="true"
app:ael_orientation="vertical">

android:layout_centerInParent="true"
android:textColor="#color/fontColor"
android:textSize="16sp" />
</com.github.aakira.expandablelayout.ExpandableRelativeLayout>
</RelativeLayout>
But, i got this ,
Edit
After removing android:layout_centerInParent="true" :
In my RecyclerViewRecyclerAdapter class, i use following:
At ViewHolder class :
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView textView;
public ListView routesAssign;
public ExpandableRelativeLayout expandableLayout;
public ViewHolder(View v) {
super(v);
textView = (TextView) v.findViewById(R.id.textView);
routesAssign = (ListView) v.findViewById(R.id.lv_routes_assigned);
expandableLayout = (ExpandableRelativeLayout) v.findViewById(R.id.expandableLayout);
}
}
At onBindViewHolder method:
holder.textView.setText(item.getDateString());
CustomAdapter testAdapter = new CustomAdapter(context, item.getRoutes());
holder.routesAssign.setAdapter(testAdapter);
holder.routesAssign.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
Intent i = new Intent(context, RoutesShapesActivity.class);
Log.e("id - onItemClick", item.getRoutes().get(pos).getId() + "-- Test --");
i.putExtra("route_id", item.getRoutes().get(pos).getId());
i.putExtra("assigned_id", item.getRoutes().get(pos).getAssignId());
i.putExtra("update", item.getRoutes().get(pos).getIsUpdated());
context.startActivity(i);
}
});
RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
item.getRoutes().size() * 200);
p.addRule(RelativeLayout.BELOW, R.id.header);
p.addRule(RelativeLayout.CENTER_IN_PARENT, R.id.header);
holder.expandableLayout.setLayoutParams(p);
holder.expandableLayout.setInterpolator(Utils.createInterpolator(Utils.DECELERATE_INTERPOLATOR));
holder.expandableLayout.setExpanded(true);
At onCreateViewHolder method :
#Override
public ViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
this.context = parent.getContext();
return new ViewHolder(LayoutInflater.from(context)
.inflate(R.layout.routes_recycler_listview, parent, false));
}
In my CustomAdapter class:
At getItem method :
#Override
public Routes getItem(int position) {
return data.get(position);
}
At getView method :
public View getView(int position, View convertView, ViewGroup parent) {
// Get the data item for this position
Routes route = getItem(position);
// Check if an existing view is being reused, otherwise inflate the view
if (convertView == null) {
convertView = inflater.inflate(R.layout.route_assigned_list, parent, false);
}
// Lookup view for data population
TextView tvName = (TextView) convertView.findViewById(R.id.route_assign_text_view);
ImageView imageView = (ImageView) convertView.findViewById(R.id.route_assign_pause_state);
Log.e("Test --- ", route.getRouteName());
tvName.setText(route.getRouteName());
return convertView;
}
My getter and setter method in Routes class. Here,
public class Routes {
//
// "assignId": 22,
// "routeId": 15,
// "routeName": "NY-CLSTR23",
// "createdDate": "2016-04-15 09:51:45"
#SerializedName("assignId")
private int assignId;
#SerializedName("assignDate")
private String assignDate;
#SerializedName("routeId")
private int id;
#SerializedName("routeName")
private String routeName;
#SerializedName("createdDate")
private String createdDate;
#SerializedName("isUpdated")
private String isUpdated;
/*"assignId": 167,
"assignDate": "2016-06-17",
"routeId": 137,
"routeName": "Test June 16",
"createdDate": "2016-06-16 00:14:27",
"isUpdated": "true"*/
public int getAssignId() {
return assignId;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getRouteName() {
return routeName;
}
public void setRouteName(String routeName) {
this.routeName = routeName;
}
public String getCreatedDate() {
return createdDate;
}
public void setCreatedDate(String createdDate) {
this.createdDate = createdDate;
}
public void setAssignId(int assignId) {
this.assignId = assignId;
}
public String getAssignDate() {
return assignDate;
}
public void setAssignDate(String assignDate) {
this.assignDate = assignDate;
}
public String getIsUpdated() {
return isUpdated;
}
public void setIsUpdated(String isUpdated) {
this.isUpdated = isUpdated;
}
}
I have really hard time here. So, what can be done to remove that space from the the listview ?

This is not done by ListView, this is done by the custom relative layout and tag which which you are using with ListView android:layout_centerInParent="true"
<ListView
android:id="#+id/lv_routes_assigned"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textColor="#color/fontColor"
android:textSize="16sp" />
So remove this attribute from ListView which will solve your problem.
<ListView
android:id="#+id/lv_routes_assigned"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#color/fontColor"
android:textSize="16sp" />
You can use android:layout_alignParentTop="true" attribute into your ListView also.

you should add a background color (eg. #F00) to see if the problem is with listview or with its container.
after that i will use this in listview
android:fillViewport="true"
not sure so just give it a try

you have android:layout_centerInParent="true" defined in your listview which is causing this, try removing that
<com.github.aakira.expandablelayout.ExpandableRelativeLayout
android:id="#+id/expandableLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="0dp" // this is just in case if your customview is setting some minheight
android:layout_below="#id/header"
android:background="#drawable/recycler_item_bg"
app:ael_duration="400"
app:ael_expanded="true"
app:ael_orientation="vertical">
<ListView
android:id="#+id/lv_routes_assigned"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#color/fontColor"
android:textSize="16sp" />
</com.github.aakira.expandablelayout.ExpandableRelativeLayout>
