What is the most efficient way to show model field information in an activity? Just like below picture for example, do they manually make each fields using View groups(LinearLayout, RelativeLayout, ConstraintLayout), or do they produce this using a RecyclerView? If this was made using a RecyclerView, how is this achievable?

UPDATE(If we're using RecyclerView):

-Thank you for the replies, I think you guys are right,I should use LinearLayout if I want to achieve just like in picture sample. But in my case, I have a lot of data, 50 fields, and I dont want to manually make 1 ViewGroup for each field. With my example, I would only be using 4 fields for my User Model, and these items are purely for viewing, no other viewtypes and no specific functions.

User Model fields:

-Name

-Age

-Gender

-Address

I want each user field as an item in a recyclerview, but since my UserModel is not a List, I wouldnt be able to fed it to the RecyclerView. Below picture is what I want to achieve. Sorry If my problem is a bit ambiguous, I'm having a hard time explaining my problem.

I would use a RecyclerView with a custom adapter to achieve this result, depending on how advanced each item can be. If it's simple interaction and design, eg icon, text and maybe a click listener then it's good enough.

If it's anything more advanced, many different types of actions that can be preformed by each button, then maybe you could just go with a LinearLayout and generate each button with their specific action.

If you would rather generate the buttons, scroll to the bottom for an example

Assuming that you want to use a RecyclerView, then it could look something like this:

You could have an adapter item looking something like this:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:orientation="horizontal"

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:padding="@dimen/padding_view_small">



    <ImageView

        android:id="@+id/icon"

        android:layout_width="25dp"

        android:layout_height="wrap_content"

        app:srcCompat="@drawable/ic_person_black_24dp"/>



    <TextView

        android:id="@+id/text"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_gravity="center_vertical"

        android:text="@string/placeholder"

        android:textColor="@color/black"

        android:layout_marginStart="@dimen/padding_view_small"

        android:layout_marginLeft="@dimen/padding_view_small"/>



</LinearLayout>

Your adapter

public class MyAdapter extends RecyclerView.Adapter

{

    private Context _context;



    private List<MyObject> _items;



    public void setItems(List<MyObject> items)

    {

        this._items = items;

        notifyDataSetChanged();

    }



    @NonNull

    @Override

    public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType)

    {

        _context = parent.getContext();

        return new MyAdapter.ItemViewHolder(parent);

    }



    @Override

    public void onBindViewHolder(@NonNull final RecyclerView.ViewHolder holder, int position)

    {

        final MyAdapter.ItemViewHolder viewHolder = (MyAdapter.ItemViewHolder) holder;

        final MyObject item = _items.get(position);



        viewHolder._icon.setImageResource(item.getIcon());

        viewHolder._name.setText(item.getText());

    }



    @Override

    public int getItemCount()

    {

        return _items != null ? _items.size() : 0;

    }



    private static class ItemViewHolder extends RecyclerView.ViewHolder

    {

        private ImageView _icon;

        private TextView _text;



        private ItemViewHolder(ViewGroup parent)

        {

            super(LayoutInflater.from(parent.getContext()).inflate(R.layout.adapter_layout, parent, false));

            this._icon = itemView.findViewById(R.id.icon);

            this._text = itemView.findViewById(R.id.text);

        }

    }

}

MyObject class for storing information about each button

public class MyObject

{

    private int _icon;

    private String _text;



    public MyObject(int icon, String text)

    {

        this._icon = icon;

        this._text = text;

    }



    public int getIcon()

    {

        return this._icon;

    }



    public int getText()

    {

        return this._text;

    }

}

Then you could also maybe directly pass a ClickListener to the MyObject, or you can also add an additional variable called Type so that you know what to do when a user clicks a specific type.

Generating buttons without a RecyclerView

You can have a basic LinearLayout view holder that's gonna hold all the views.

<LinearLayout

    android:id="@+id/action_holder"

    android:layout_width="match_parent"

    android:layout_height="wrap_content"

    android:orientation="vertical"/>

Method for generating views

private View generateView(int icon, String text)

{

    LayoutInflater inflater = LayoutInflater.from(_context);

    View view = inflater.inflate(R.layout.adapter_layout, null);



    ImageView icon = view.findViewById(R.id.icon);

    icon.setImageResource(icon);



    TextView text = view.findViewById(R.id.text);

    text.setText(text);



    return view;

}

Dynamically adding new views

View showDialogView = generateView(ContextCompat.getDrawable(_context, R.drawable.test), "Show dialog");

//Here you can set a click listener to what should happen when you click the item

showDialogView.setOnClickListener....



linearLayout.addView(showDialogView);

As you have explained me in the comments.

• You have a Model class USER which has 50 fields.


• And if the items look like as they are in Screenshot.

If this is the case, it can be easily solved with Simple RecyclerView without even using ViewType

Your ItemView has a logo, a title, and a description.

1) Create a new Model for items of the List.

class ListItem{



   int logo;

   int title;

   int desc;



   // write getter and setter



}

2) Populate list?

Get data from User Model and convert it to ListItem Model

Lets say that first item is Name of the user.

Do like this

 ListItem username = new ListItem();

   username.setTitle("NAME");

   username .setLogo(R.id.userLogo);

   username.setDesc(user.name);

Lets say that second item is Age of the user

Do like this

 ListItem age = new ListItem();

   age.setTitle("AGE");

   username .setLogo(R.id.ageLogo);

   username.setDesc(user.age);

3) Feed the itemList in the Adapter

List<ListItem> myList = new List<ListItem>();

myList.add(username);

myList.add(age);



YourAdapter adapter = new Adapter(context,myList);

recyclerView.setAdapter(adapter);

Hope this helps. Peace:)
