Card layout parameters not working

Card layout parameters not working - java

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>

my error like this
why my imageview working but textview not working
thank you for attention

mOnItemClickListener.onItemClick(view, checkList.get(getAdapterPosition()), getAdapterPosition(), list.get(getAdapterPosition()));
change to
mOnItemClickListener.onItemClick(v, checkList.get(getAdapterPosition()), getAdapterPosition(), list.get(getAdapterPosition()));

This is because the id tvKonten does not exist. In your XML code, the id of the TextView is txtsuka, not tvKonten. Change tvKonten to txtsuka.

Try these options, it might work for you :
Invalidate Caches and Restart
Check if you have a different version of the same layout file in your res folder such as ...v26.xml or something like that ; if you find any then delete the unwanted version of the file.

How to get total of all items in recycler view

I have recycler view and spinner in activity depending on spinner value post request has been sent to server after which recycler view populated in which every row have some cost. I want to add this cost of every row.
Screenshot is given below:
In screenshot we can see No. of quantities are 2 which cost 40 like this other row also have some value.SO I want to add all these costs from each row and showing it in lower left area where ToTAL is written.
Here is my code:

You can use array and append the value of each cell in it and never clear it, then create a function in your adapter that return with this array, here you cal add it's items.

Getting the progress of multiple seekbars in recycler view

So I am displaying a recylerview with an Image and the name of a person. Below that is a seekbar, which the user can move to rate that person.
Now I want to store the ratings (=progress) of each seekbar in a list. However right now it only stores the rating of the last seekbar in the list.
So it stores only the progress of the last seekbar right now. I would like that when the user clicks the button that every current rating value of every seekbar is stored in a list.
Thank you very much.

You can do it in multiple ways:
1- You can store seekbars value as a property in your model and update that property on OnSeekBarChangeListener and when the user hits the button get the data source from the adapter and then run a loop on it and call getter of that attribute.
2- You can store seekbars value as a List<> in your adapter and whenever the user hits the button get the list from the adapter.

EDIT: Screenshot added
EDIT2: Clarified parent fragment calling the adapter.
EDIT3: I did a temporary fix. Apparently the RelativeLayout and the Linear Layout in the AdapterXML were the cause of my misery. I'm not exactly sure why, though. I think it's the RelativeLayout and the LinearLayout somehow not displaying the text. Removing those two tags will display the texts in a linear fashion.

Recycler View and Card View not displaying cards

This is my Activity:

public String passPhrase;
public ArrayList<SongCell> songs;
private RecyclerView recyclerView;
private MyAdapter myAdapter;
private RecyclerView.LayoutManager layoutManager;
#TargetApi(Build.VERSION_CODES.JELLY_BEAN)
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.songs_view_layout);
Context context = this.getApplicationContext();
Bundle stateData = getIntent().getExtras();
try
{
id = stateData.getString("id");
passPhrase = stateData.getString("passPhrase");
ArrayList data;
recyclerView = (RecyclerView) findViewById(R.id.song_list);
recyclerView.setHasFixedSize(true);
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
data = new ArrayList<SongCell>();
for (int i=0; i<5;i++)
{
data.add(new SongCell("Song "+i,"Artist "+i, null));
}
myAdapter = new MyAdapter(data);
recyclerView.setAdapter(myAdapter);
}
catch(Exception e)
{
Log.d("Error: ", e.toString());
}

And this is my custom adapter
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>
{
private ArrayList<SongCell> data;
public MyAdapter(ArrayList<SongCell> dataI)
{
data = dataI;
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType)
{
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.song_card,viewGroup,false);
return new ViewHolder(view);
}
#Override
public void onBindViewHolder(ViewHolder viewholder, int pos) {
viewholder.songName.setText(data.get(pos).getName());
viewholder.artist.setText(data.get(pos).getArtist());
viewholder.image.setImageBitmap(data.get(pos).getArtwork());
}
#Override
public int getItemCount() {
return 0;
}
#Override
public int getItemViewType(int position) {
return 0;
}
public class ViewHolder extends RecyclerView.ViewHolder
{
TextView songName;
TextView artist;
ImageView image;
ImageButton voteButton;
public ViewHolder(View v)
{
super(v);
this.songName = (TextView) v.findViewById(R.id.song_name);
this.image = (ImageView) v.findViewById(R.id.song_photo);
this.voteButton = (ImageButton) v.findViewById(R.id.vote_button);
}
}
}
I have looked at a ton of guides on how to get this working but it still doesn't work. Anyone have any clue what's going on? I'm on version 25.0.1, and have all the modules imported. But it's not adding a single card into the layout.

I thought it would be difficult to debug such a big code you uploaded. But luckily my eye went on this line
#Override
public int getItemCount() {
return 0;
}
return 0; in adapter.
Your list size is always 0.
instead write this
#Override
public int getItemCount() {
return data.size();
}
EDIT-1:
You will also get null pointer exception here
viewholder.artist.setText(data.get(pos).getArtist());
Because you are not initializing the artist variable in ViewHolder class.
Edit-2
#Override
public int getItemCount() {
return 0;
}
you can remove this particular code from your adapter. Because overriding the methods of class that we don't use might sometimes result in errors that you can't even imagine.
