CardView not displaying content due any errors

CardView not displaying content due any errors - java

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"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:orientation="vertical">
<android.support.v7.widget.CardView
android:id="#+id/card_view1"
android:layout_width="match_parent"
android:layout_height="288dp"
android:layout_margin="#dimen/card_margin"
android:elevation="3dp"
card_view:cardCornerRadius="0dp"
android:gravity="top">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/card"
android:focusable="true"
android:contextClickable="true"
android:gravity="top"
android:layout_alignParentBottom="true">
</RelativeLayout>
</android.support.v7.widget.CardView>
<TextView
android:id="#+id/title1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="10dp"
android:paddingRight="25dp"
android:paddingTop="10dp"
android:textColor="#color/cardview_dark_background"
android:textSize="15dp"
android:layout_above="#+id/count1"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<ImageView
android:id="#+id/thumbnail1"
android:layout_width="match_parent"

android:paddingRight="25dp"
android:textSize="12dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</LinearLayout>
This is My HotelPageList.java :
package ir.homa;
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 ?

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.

Losing styles when inheriting from Material Card View Group

styles
<style name="AppTheme" parent="Theme.MaterialComponents">
<item name="materialCardViewStyle">#style/Widget.MaterialComponents.CardView</item>
</style>

note that your CaseView IS a MaterialCardView (extends), but you have also another MaterialCardView as a root of your inflated XML. this is another View without style set (no xml style attr), in fact your CaseView contains one child - another MaterialCardView.
imho it should respect "global" setting from AppTheme, but still worth fix this double-CardView case - use <merge tag instead of root MaterialCardView in XML. inflate method will add all childs placed inside <merge> tag to CaseView

SharedElementTransition on fragment dont work

I want to add shared element transition to items in a recyclerview which will opened on another fragment, but nothing works.
The only view that i want to share is an ImageView.
ImageViews and Textviews inside recyclerview items are loaded using Glide for images and firebase database methods for texts. In the detailed fragment, the bitmap of recyclerview item is passed and only the text is downloaded again.
the method which opens the new fragment from recyclerview items is :
homeUserAnnouncesAdapter.setOnCardAnnounceClickedListener(new OnCardAnnounceClickedListener() {
#Override
public void onCardClicked(CardRentAnnounce card, ImageView imageView, int poz) {
Log.v("TRANSITIONTEST", "CLICKED FROM HOME FRAGMENT --- RENT");
Log.v("TRANSITIONTEST", "in onClick: " + imageView.getTransitionName());
Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();
OpenRentAnnounceFragment newFragment = OpenRentAnnounceFragment.newInstanceWithImage(card, bitmap, poz);
newFragment.setSharedElementEnterTransition(new DetailsTransition());
newFragment.setEnterTransition(new Fade());
newFragment.setExitTransition(new Fade());
newFragment.setSharedElementReturnTransition(new DetailsTransition());
getActivity().getSupportFragmentManager()
.beginTransaction()
.addSharedElement(imageView, imageView.getTransitionName())
.replace(R.id.content_main_without_toolbar, newFragment)
.addToBackStack(null)
.commit();
}
});
the DetailsTransition class is :
public class DetailsTransition extends TransitionSet{
public DetailsTransition() {
init();
}
/**
* This constructor allows us to use this transition in XML
*/
public DetailsTransition(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
private void init() {
setOrdering(ORDERING_TOGETHER);
addTransition(new ChangeBounds())
.addTransition(new ChangeTransform())
.addTransition(new ChangeImageTransform());
}
}
i'm assigning different transition names for every view, on adapter:
#Override
public void onBindViewHolder(final HomeUserAnnouncesViewHolder holder, int position) {
final CardRentAnnounce cardRentAnnounce = cardRentAnnounceArrayList.get(position);
holder.updateUI(cardRentAnnounce);
ViewCompat.setTransitionName(holder.rentImage, String.valueOf(position) + "_rent");
MaterialRippleLayout mlr = (MaterialRippleLayout)holder.itemView.findViewById(R.id.search_home_ripple);
mlr.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(listener != null){
listener.onCardClicked(cardRentAnnounce, holder.rentImage, holder.getAdapterPosition());
}
}
});
}
the id of image in recyclerview item is identically with the image in fragment
i have followed this tutorial to create the transition, even cloned the project to my pc, run on emulator and trying to do exactly like in the working project but still not working.
how i set the image and imageTransition name in new fragment :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_open_rent_announce, container, false);
rootView = view;
image = (ImageView)view.findViewById(R.id.detailed_image);
image.setImageBitmap(currentImageBitmap);
image.setTransitionName(String.valueOf(pozition) + "_rent");
Log.v("TRANSITIONTEST", "in onCreateView: " + image.getTransitionName());
initViews(view);
setViews();
return view;
}
Fragment SharedElementsTransition tutorial
both images on recyclerview and detailed fragment are loaded with Glide, but i've tried with local images and still no succes.
What did i'm missing? ask for more code if needed.
Thanks.

RecyclerView with GridLayoutManager left justifies views

I am trying to add a RecyclerView with GridLayoutManagerto my app. Everything works as expected, only problem is it seems the columns are left justified instead of center justified. Any ideas? Thanks in advance!
Here is an image showing how it looks:
Here is the single item layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:background="?android:selectableItemBackgroundBorderless"
android:clickable="true"
android:gravity="center_horizontal"
android:orientation="vertical">
<ImageView
android:id="#+id/iconSpot"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_gravity="center_horizontal"
android:src="#drawable/ic_launcher"
tools:ignore="MissingPrefix" />
<TextView
android:id="#+id/textLabel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="Dummy Text"
android:textSize="16sp" />
</LinearLayout>
And here is the full activity layout:
<?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:id="#+id/totalScreen"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignTop="#+id/fab"
android:layout_gravity="bottom|center"
android:gravity="bottom|center_vertical">
<TextView
android:id="#+id/sheetTitle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#424242"
android:padding="12dp"
android:text="Dummy Title"
android:textSize="18sp" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignTop="#+id/sheetTitle"
android:layout_marginEnd="20dp"
android:layout_marginTop="-28dp"
android:visibility="gone"
app:fabSize="normal" />
<android.support.v7.widget.RecyclerView
android:id="#+id/gridScreen"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/sheetTitle"
android:background="#424242"
android:gravity="bottom|center"
android:layout_gravity = "center"
android:orientation="vertical"
android:paddingBottom="24dp" />
</RelativeLayout>

Ok! I figured it out, it ended up being the fact that I needed to make the item layout width set as match_parent instead of wrap_content. So that makes it look like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_margin="10dp"
android:background="?android:selectableItemBackgroundBorderless"
android:clickable="true"
android:orientation="vertical">
<ImageView
android:id="#+id/iconSpot"
android:layout_width="44dp"
android:layout_height="44dp"
android:layout_gravity="center_horizontal"
android:src="#drawable/ic_launcher"
tools:ignore="MissingPrefix" />
<TextView
android:id="#+id/textLabel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="Dummy Text"
android:textSize="16sp" />
</LinearLayout>

It is hard to fix with just the layout file since the item layout needs to be inflated and attached to the main layout in order to see the result.
So I decided to recreate it. I made modification to your layout file.
item layout
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#color/colorPrimary"
android:layout_margin="2dp"
android:clickable="true"
android:orientation="vertical">
<ImageView
android:id="#+id/iconSpot"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_gravity="center_horizontal"
android:src="#android:drawable/ic_delete"
tools:ignore="MissingPrefix" />
<TextView
android:id="#+id/textLabel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="Dummy Text"
android:textSize="16sp" />
</LinearLayout>
