how to get data from mysql database into recycler view?

I am making an app that let users create meetings and I would like the details of the meeting (eg name, type, location) in a recycler view.I ran the php code by itself and was able to get the values from the database.
Currently, I am getting an error of
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference
at in recyclerviewAdapter
holder.Name.setText(users.getName());
holder.Type.setText(users.getType());
holder.Location.setText(users.getLocation());
which is linked to
public class Users {
private String name,type,location;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getLocation() {
return location;
}
public void setLocation(String location) {
this.location = location;
}
}

instead of
public UserHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View userLayout= LayoutInflater.from(parent.getContext()).inflate(R.layout.activity_main2,parent,false);
return new UserHolder(userLayout);
}
use this
public UserHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View userLayout= LayoutInflater.from(parent.getContext()).inflate(R.layout.activity_list ,parent,false);
return new UserHolder(userLayout);
}
because activity_main2 doesn't contain R.id.textTitle,R.id.textType,R.id.textLocation

check your xml(R.layout.activity_main2) looks like id of your view are from another layout

Android Studio calculate total price

I wanna ask how can I sum all patty price and display in the total ? The total is in activity_main.xml layout while all the product price is in view_product.xml .
Screenshot of app
As you can see the grey color text is per patty price , and the right side black text is price after multiply the quantity of patty. I want all the black text to sum up and show at below total.

In view_product.xml you are only displaying the price, but that's not where the actual data is located so your question shouldn't be that the prices are in view_product.xml and you want to show in activity_main.xml, but your question should be -
Where is the data located
How to make the necessary calculations
Where to show it. .
Your data regarding the prices are in products object. So, in order to calculate the total you just need to add one more method which calculates the total
private double calculateTotal(ProductDataSet productDataSet) {
double totalPrice = 0.0;
for(int i=0; i<productDataSet.size(); i++) {
totalPrice += productDataSet.get(i).getPrice();
}
return totalPrice;
}
The result of this you can store in a new value or show directly in the textView itself.
((TextView)findViewById(R.id.finalTotalPrice)).setText(calculateTotal(products).toString());
This you can call anywhere after createInitialProductList(). I hope this helps and makes it clear for you.

RecylerView items collapsed data to display

I have a RecyclerView which has items to display from REST API response when user choosed to load more data. However the data which binded to onBindViewHolder collapsed on the item.
The collapsed data is shown in the image below:
The orange and black text are come from different data list
The code to set data list to adapter when user choosed load more data:
mAdapter = new MaterialsRecyclerView(username, datePost, contentPost,
userPicturePost, contentType, titlePost, contentLabel, activityLabel, numberFavorite,
numberUpvote, numberDownvote, numberComments, upvoteStatus, downvoteStatus, favoriteStatus, getActivity(),
newsType, newsMedia, contentId, activityType
);
mRecyclerView.setAdapter(mAdapter);
I tried
mAdapter.notifyDataSetChanged();
after add data to data list in adapter but the data still collapsed.
My question is why collapsed data happened? And how to make the data not collapsed? I mean the data just loaded from data list suitable with the index.
Edit

In your layout you have several views with
android:layout_below="#+id/user_picture"
so they are drawn on top of each other

CardView not displaying content due any errors

I created a Recyclerview in my main_activity and I wanted to use this cardview in a partial activity... I put extras variables and data to the new activity but any thing not showing in new activity...
this is my partial xml code (hotel_page.xml) :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

This is My HotelPageList.java :

public class HotelPageList {
private String name;
private int numOfRooms;
private int thumbnail;
public HotelPageList() {
}
public HotelPageList(String name, int numOfRooms, int thumbnail) {
this.name = name;
this.numOfRooms = numOfRooms;
this.thumbnail = thumbnail;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNumOfRooms() {
return numOfRooms;
}
public void setNumOfRooms(int numOfRooms) {
this.numOfRooms = numOfRooms;
}
public int getThumbnail() {
return thumbnail;
}
public void setThumbnail(int thumbnail) {
this.thumbnail = thumbnail;
}
}
This is HotelPageAdapter.java :
package ir.homa;
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.bumptech.glide.Glide;
import java.util.List;
/**

*/
public class HotelPageAdapter extends RecyclerView.Adapter<HotelPageAdapter.MyViewHolder> {
private Context mContext;
private List<HotelPageList> hotelPage;
public class MyViewHolder extends RecyclerView.ViewHolder {
public TextView title1, count1;
public ImageView thumbnail1, overflow1;
public MyViewHolder(View view) {
super(view);
title1 = (TextView) view.findViewById(R.id.title1);
count1 = (TextView) view.findViewById(R.id.count1);
thumbnail1 = (ImageView) view.findViewById(R.id.thumbnail1);
overflow1 = (ImageView) view.findViewById(R.id.overflow);
}
}
public HotelPageAdapter(Context mContext, List<HotelPageList> hotelPage) {
this.mContext = mContext;
this.hotelPage = hotelPage;
}
#Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.hotel_page, parent, false);
return new MyViewHolder(itemView);
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
final HotelPageList hotel = hotelPage.get(position);
holder.title1.setText(hotel.getName());
holder.count1.setText(hotel.getNumOfRooms() + " اتاق");
// loading hotel cover using Glide library
Glide.with(mContext).load(hotel.getThumbnail()).into(holder.thumbnail1);
}
#Override
public int getItemCount() {return hotelPage.size();}
}
and this is result:
Where is problem ?

Card layout parameters not working

I am trying to implement a list of Card views, and the list is fine, but the layout inside the card is nothing like what i have defined in the XML. Any ideas why this is not showing properly? Here is my card XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
android:id="#+id/cvAdvertFavourite"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dip"
android:layout_marginBottom="2dip"
card_view:cardUseCompatPadding="true"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="8dp"
>
<ImageView
android:id="#+id/ivCardFavouriteAnimalPhoto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginRight="8dp"
/>
<TextView
android:id="#+id/tvCardFavouriteTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/ivCardFavouriteAnimalPhoto"
android:textSize="30sp"
/>
<TextView
android:id="#+id/tvCardFavouriteRace"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tvCardFavouriteTitle"
android:layout_toRightOf="#+id/ivCardFavouriteAnimalPhoto"
/>
<TextView
android:id="#+id/tvCardFavouritePrice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tvCardFavouriteRace"
android:layout_toRightOf="#+id/ivCardFavouriteAnimalPhoto"
/>
</RelativeLayout>
</android.support.v7.widget.CardView>
I use this RecyclerView XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="16dp"
>
<android.support.v7.widget.RecyclerView
android:id="#+id/rvCardFavourite"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
Here is my CardItem class:
public class FavouriteCardItem {
Bitmap animal;
int price;
String title, race;
public FavouriteCardItem(Bitmap animal, int price, String title, String race){
this.animal = animal;
this.price = price;
this.title = title;
this.race = race;
}
public Bitmap getAnimal() {
return animal;
}
public void setAnimal(Bitmap animal) {
this.animal = animal;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getRace() {
return race;
}
public void setRace(String race) {
this.race = race;
}
}
Here is how I call my adapter and set the data for the adapter:
private void loadSetData() {
List<FavouriteCardItem> items = new ArrayList<FavouriteCardItem>();
Bitmap bitmap = BitmapFactory.decodeResource(getActivity().getResources(),
R.drawable.bird);
FavouriteCardItem item1 = new FavouriteCardItem(bitmap, 100, "birds", "birds");
items.add(item1);
Bitmap bitmap2 = BitmapFactory.decodeResource(getActivity().getResources(),
R.drawable.dog);
FavouriteCardItem item2 = new FavouriteCardItem(bitmap2, 200, "dogs", "dogs");
items.add(item2);
Bitmap bitmap3 = BitmapFactory.decodeResource(getActivity().getResources(),
R.drawable.cat);
FavouriteCardItem item3 = new FavouriteCardItem(bitmap3, 1000, "cats", "cats");
items.add(item3);
FavouriteCardAdapter adapter = new FavouriteCardAdapter(getActivity(), R.layout.card_view, items);
recyclerView.setAdapter(adapter);
}
And this is my Adapter class:
public class FavouriteCardAdapter extends RecyclerView.Adapter<FavouriteCardAdapter.CardViewHolder> {
private Context mContext;
private int resourceId;
List<FavouriteCardItem> cardItems;
public FavouriteCardAdapter(Context context, int resource, List<FavouriteCardItem> cardItems){
mContext = context;
resourceId = resource;
this.cardItems = cardItems;
}
#Override
public CardViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_view, parent, false);
CardViewHolder cvh = new CardViewHolder(v);
return cvh;
}
#Override
public void onBindViewHolder(CardViewHolder holder, int position) {
DisplayMetrics metrics = Resources.getSystem().getDisplayMetrics();
int screenHeight = metrics.heightPixels;
holder.cardView.getLayoutParams().height = screenHeight / 4;
int price = cardItems.get(position).getPrice();
String price1 = Integer.toString(price);
holder.tvPrice.setText(price1);
holder.tvRace.setText(cardItems.get(position).getRace());
holder.tvTitle.setText(cardItems.get(position).getTitle());
holder.ivAnimal.setImageBitmap(cardItems.get(position).getAnimal());
}
#Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
#Override
public int getItemCount() {
return cardItems.size();
}
public class CardViewHolder extends RecyclerView.ViewHolder{
CardView cardView;
ImageView ivAnimal;
TextView tvPrice, tvTitle, tvRace;
public CardViewHolder(View itemView) {
super(itemView);
cardView = (CardView) itemView.findViewById(R.id.cvAdvertFavourite);
ivAnimal = (ImageView) itemView.findViewById(R.id.ivCardFavouriteAnimalPhoto);
tvPrice = (TextView) itemView.findViewById(R.id.tvCardFavouritePrice);
tvTitle = (TextView) itemView.findViewById(R.id.tvCardFavouriteTitle);
tvRace = (TextView) itemView.findViewById(R.id.tvCardFavouriteRace);
}
}
}
BTW I am aware that I am not supposed to load images like this and so on, but I just wanted to create some test data to get the layout right before i start loading the data from the online data storage.
Here is how the whole Card view looks like. It should have 3 textViews and 1 imageView, but it only shows one imageView.....

You can try this as one of the solution if you do not want to specify the dimension for width and height of Image
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
android:id="#+id/cvAdvertFavourite"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dip"
android:layout_marginBottom="2dip"
card_view:cardUseCompatPadding="true"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:padding="8dp"
>
<ImageView
android:id="#+id/ivCardFavouriteAnimalPhoto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="8dp"
android:weight = "2"/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:weight = "1" />
<TextView
android:id="#+id/tvCardFavouriteTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:textSize="20sp"
/>
<TextView
android:id="#+id/tvCardFavouriteRace"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tvCardFavouriteTitle"
/>
<TextView
android:id="#+id/tvCardFavouritePrice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tvCardFavouriteRace"
/>
</RelativeLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
In this I have used LinearLayout which will distribute the screen width in the ratio 2:1 between ImageView and RelativeLayout with text.
Also I have reduced the size of text from 30sp to 20sp

try to make your card xml look like this:
<android.support.v7.widget.CardView
android:id="#+id/cvAdvertFavourite"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="2dip"
android:layout_marginBottom="2dip"
card_view:cardUseCompatPadding="true"
>
<RelativeLayout
android:id="#+id/something"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
>
<ImageView
android:id="#+id/ivCardFavouriteAnimalPhoto"
android:layout_width="#dimen/your_size_of_image" // the important part
android:layout_height="#dimen/your_size_of_image" // the important part
android:layout_centerVertical="true"
android:scaleType="centerCrop"/>
<LinearLayout // make sure you are using a linearlyout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toEndOf="#id/ivCardFavouriteAnimalPhoto"
android:layout_toRightOf="#id/ivCardFavouriteAnimalPhoto"
android:orientation="vertical">
<TextView
android:id="#+id/tvCardFavouriteTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" />
<TextView
android:id="#+id/tvCardFavouriteRace"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" />
<TextView
android:id="#+id/tvCardFavouritePrice"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" />
</LinearLayout>
</RelativeLayout>
</android.support.v7.widget.CardView>
