Switch between RecyclerView layouts when click on

Question

I have three different layouts cardsListLayout , titleLayout , cardMagazineLayoutand there may be more in the future, which used as a views on onCreateViewHolder method.

I want to switch between views in onCreateViewHolder method so when user choose from AlertDialog list

this onOptionsItemSelected in MainActivity Where there is menu Item "change the layout" so that when the user presses it it appears AlertDialog list

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == R.id.change_layout) {
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle(getString(R.string.choose_layout));

            String[] layouts = {"Title Layout", "Cards List", "Card Magazine Layout"};
            builder.setItems(layouts, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int index) {
                    switch (index) {
                        case 0: // Title layout
                            Toast.makeText(MainActivity.this,
                                    "Title layout", Toast.LENGTH_LONG).show();
                            break;
                        case 1: // Cards List
                            Toast.makeText(MainActivity.this,
                                    "Card list", Toast.LENGTH_LONG).show();
                            break;
                        case 2: // Cards Magazine Layout
                            Toast.makeText(MainActivity.this,
                                    "Card Magazine Layout", Toast.LENGTH_LONG).show();
                    }
                }
            });

and this my custom adapter class PostAdapter

public class PostAdapter extends RecyclerView.Adapter<PostAdapter.PostViewHolder> {
    private Context context;
    private List<Item> items;

    public PostAdapter(Context context, List<Item> items) {
        this.context = context;
        this.items = items;
    }

    @NonNull
    @Override
    public PostAdapter.PostViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(context);

// here's the three layouts that I can't switch between it

        View cardsListLayout = inflater.inflate(R.layout.post_item_card_layout, parent, false);
        View titleLayout = inflater.inflate(R.layout.post_item_grid_layout, parent, false);
        View cardMagazineLayout = inflater.inflate(R.layout.card_magazine_layout,parent,false);

        return new PostViewHolder(titleLayout);
    }

    @Override
    public void onBindViewHolder(@NonNull PostViewHolder holder, int position) {
        final Item item = items.get(position);
        holder.postTitle.setText(item.getTitle());
        final Document document = Jsoup.parse(item.getContent());
        Elements elements = document.select("img");


        Log.e("CODE", "Image: " + elements.get(0).attr("src"));
//        Log.d("Text",document.text());
//        holder.postDescription.setText(document.text());

        Glide.with(context).load(elements.get(0).attr("src"))
                .into(holder.postImage);

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(context, DetailsActivity.class);
                intent.putExtra("url", item.getUrl());
                intent.putExtra("title", item.getTitle());
                intent.putExtra("content", item.getContent());
                int youtubeThumbnailImagesetVisibility = 0;

                Element element = document.body();

                String youtubeThumbnailImageSrc = "";
                String youTubeLink = "";
                for (Element e : element.getElementsByClass
                        ("YOUTUBE-iframe-video")) {
                    youtubeThumbnailImageSrc = e.attr("data-thumbnail-src");
                    youTubeLink = e.attr("src");
                    Log.e("YouTube thumbnail", youtubeThumbnailImageSrc);
                    Log.e("Youtube link", youTubeLink);
                }

                if (youtubeThumbnailImageSrc.isEmpty()) {
                    youtubeThumbnailImagesetVisibility = 8;
                    intent.putExtra("youtubeThumbnailImagesetVisibility",
                            youtubeThumbnailImagesetVisibility);
                } else {
                    intent.putExtra("youtubeThumbnailImageSrc", youtubeThumbnailImageSrc);
                    intent.putExtra("youTubeLink", youTubeLink);
                }

//             String imageSrc = elements.get(0).attr("src");
//             intent.putExtra("blogImage",imageSrc);

                context.startActivity(intent);
            }
        });

    }

    @Override
    public int getItemCount() {
        return items.size();
    }

    public class PostViewHolder extends RecyclerView.ViewHolder {

        ImageView postImage;
        TextView postTitle;
        TextView postDescription;

        public PostViewHolder(View itemView) {
            super(itemView);
            postImage = itemView.findViewById(R.id.postImage);
            postTitle = itemView.findViewById(R.id.postTitle);
            postDescription = itemView.findViewById(R.id.postDescription);

        }
    }

}

I created two different Layout Manager for each one, there's a LinearLayoutManager and GridLayoutManager, currently I used GridLayout so I commented the LinearLayoutManger temporarily until I know how to switch between them

//      linearLayoutManager = new LinearLayoutManager(this);
        gridLayoutManager = new GridLayoutManager(this, 2, RecyclerView.VERTICAL, false);
//        recyclerView.setLayoutManager(linearLayoutManager);
        recyclerView.setLayoutManager(gridLayoutManager);

The result I aspire to

Answer 1

To prevent mixed layout when scrolling you should use ViewFlipper with three different RecyclerView's , meaning RecyclerView for each layout.

Step 1:

• Create a public enum for the three layouts

public enum ViewType {
    CARD_LIST_LAYOUT, TITLE_LAYOUT, CARD_MAGAZINE_LAYOUT;
}

• In PostAdapter create a ViewType variable and pass it into constructor, and checking via if & else on onCreateViewHolder to know Which layout choosed

PostAdapter(Context context, List<Item> items, ViewType viewType) {
        this.context = context;
        this.items = items;
        this.viewType = viewType;
    }



    @NonNull
    @Override
    public PostAdapter.PostViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(context);

        View cardListLayout = inflater.inflate(R.layout.post_item_card_layout, parent, false);
        View titleLayout = inflater.inflate(R.layout.post_item_grid_layout, parent, false);
        View cardMagazineLayout = inflater.inflate(R.layout.card_magazine_layout, parent, false);

        if (this.viewType == ViewType.TITLE_LAYOUT) {
            return new PostViewHolder(titleLayout);
        } else if (this.viewType == ViewType.CARD_LIST_LAYOUT) {
            return new PostViewHolder(cardListLayout);
        } else {
            return new PostViewHolder(cardMagazineLayout);
        }
    }

Step 2:

• Create a ViewFlipper in the class that contains the main RecyclerView, with three child's Layout's and RecyclerView's

<ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/parentLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity"
    >


        <LinearLayout
            android:id="@+id/linearLayout1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/titleRecyclerView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                >

            </androidx.recyclerview.widget.RecyclerView>

        </LinearLayout>


        <LinearLayout
            android:id="@+id/linearLayout2"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/cardRecyclerView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                >


            </androidx.recyclerview.widget.RecyclerView>

        </LinearLayout>


        <LinearLayout
            android:id="@+id/linearLayout3"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/cardMagazineRecyclerView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                >

            </androidx.recyclerview.widget.RecyclerView>


        </LinearLayout>

    </RelativeLayout>

</ViewFlipper>

• In MainActivity define variable's like this

         viewFlipper = ((ViewFlipper) findViewById(R.id.parentLayout));


        titleRecyclerView = (RecyclerView) findViewById(R.id.titleRecyclerView);
        cardRecyclerView = (RecyclerView) findViewById(R.id.cardRecyclerView);
        cardMagazineRecyclerView = (RecyclerView) findViewById(R.id.cardMagazineRecyclerView);



        linearLayoutManager1 = new LinearLayoutManager(this);
        cardRecyclerView.setLayoutManager(linearLayoutManager1);
        linearLayoutManager2 = new LinearLayoutManager(this);
        cardMagazineRecyclerView.setLayoutManager(linearLayoutManager2);

        gridLayoutManager = new GridLayoutManager(this, 2, RecyclerView.VERTICAL, false);
        titleRecyclerView.setLayoutManager(gridLayoutManager);


        adapter1 = new PostAdapter(this, items, ViewType.TITLE_LAYOUT);
        titleRecyclerView.setAdapter(adapter1);
        adapter2 = new PostAdapter(this, items, ViewType.CARD_LIST_LAYOUT);
        cardRecyclerView.setAdapter(adapter2);
        adapter3 = new PostAdapter(this, items, ViewType.CARD_MAGAZINE_LAYOUT);
        cardMagazineRecyclerView.setAdapter(adapter3);

• add ScrollListener for each RecyclerView

titleRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
                if (newState == AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL) {

                }

            }

            @Override
            public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);
                if (dy > 0) {

                }

            }  
        });

cardRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
                if (newState == AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL) {

                }

            }

            @Override
            public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);
                if (dy > 0) {

                }

            }  
        });

cardMagazineRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
                super.onScrollStateChanged(recyclerView, newState);
                if (newState == AbsListView.OnScrollListener.SCROLL_STATE_TOUCH_SCROLL) {

                }

            }

            @Override
            public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
                super.onScrolled(recyclerView, dx, dy);
                if (dy > 0) {

                }

            }  
        });

Step 3:

• And finally on onOptionsItemSelected switch between three layout when click

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == R.id.change_layout) {
            AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle(getString(R.string.choose_layout));

            String[] layouts = {"Title Layout", "Cards List", "Card Magazine Layout"};
            builder.setItems(layouts, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int index) {
                    switch (index) {
                        case 0: // Title layout
                            viewFlipper.setDisplayedChild(0);

                            break;
                        case 1: // Cards List Layout
                            viewFlipper.setDisplayedChild(1);
                            break;
                        case 2: // Cards Magazine Layout
                            viewFlipper.setDisplayedChild(2);
                    }
                }
            });

            AlertDialog dialog = builder.create();
            dialog.show();
            return true;
        }

[Important Note] you should doing any implementation of the old main RecyclerView three times each one for every layout or RecyclerView like the above example of ScrollListener.

Hope this working with you, and please inform me if you have any inquiries

Answer 2

You can simply achieve this by implementing VIEW_TYPE inside your adapter. There is a overridden method in RecyclerView Adapter public int getViewType(int position), generally this method is used for mixing various types of views into a RecyclerView.

But you can use this in your case too. First define an enumeration of your view types. Then inside your adapter maintain a variable to store the current viewType, update that variable accordingly from the alert dialog item click.

Use that current viewType value into your onCreateViewHolder and onBindViewHolder methods to determine which layout you should use currently and which UI elements need to be updated now. Also update the RecyclerView layout manager from the alert dialog items on click.

public class PostAdapter extends RecyclerView.Adapter<PostAdapter.PostViewHolder> {

    public enum ViewType {
         VIEW_TYPE_GRID, VIEW_TYPE_CARD, VIEW_TYPE_CARD_MAGAZINE
    }

    private Context context;
    private List<Item> items;
    private ViewType currentViewType;

    public PostAdapter(Context context, List<Item> items, ViewType viewType) {
        this.context = context;
        this.items = items;
        this.currentViewType = viewType;
    }

    // Call this method from alert dialog item click.
    public void updateViewType(ViewType type) {
        this.currentViewType = type;
    }

    @Override
    public int getItemViewType(int position) {
        return this.currentViewType.ordinal();
    }

    @Override
    public int getItemCount() {
        return items.size();
    }

    @Override
    public PostAdapter.PostViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(context);

        // here's the layouts that you want to switch between, based on the viewType
        if (viewType == ViewType.VIEW_TYPE_CARD.ordinal()) {
            View cardLayout = inflater.inflate(R.layout. post_item_card_layout, parent, false);
            return new PostViewHolder(cardLayout);
        }
        else if (viewType == ViewType.VIEW_TYPE_GRID.ordinal()) {
            View gridLayout = inflater.inflate(R.layout. post_item_grid_layout,parent,false);
            return new PostViewHolder(gridLayout);
        }
        else {
            View cardMagazineLayout = inflater.inflate(R.layout. card_magazine_layout, parent, false);
            return new PostViewHolder(cardMagazineLayout);
        }
    }

    @Override
    public void onBindViewHolder(@NonNull PostViewHolder holder, int position) {
        final Item item = items.get(position);
        // Similarly handle different view layout items here based on the viewType returned from getItemViewType method.
        if (getItemViewType(position) == ViewType.VIEW_TYPE_CARD.ordinal()) {

        } else if (getItemViewType(position) == ViewType.VIEW_TYPE_GRID.ordinal()) {

        } else {

        }
    }
}

Update: Every time you called the updateViewType method you also need to call the notifyDataSetChanged method like this:

mAdapter.updateViewType(PostAdapter.ViewType.VIEW_TYPE_GRID);
mAdapter.notifyDataSetChanged()

*** I have tested this code on my device and it is working as expected. Please note that you should carefully handle the VIEW_TYPE when inflating layouts and using layout elements like TextView and ImageView. In my previous answer I have mixed up the view types with wrong layouts, that might be the only reason so that you have seen mixed layouts as output.

*** Also, the getItemViewType method was mistakenly renamed as getViewType and that was another culprit in my code which causes mixed output.

Answer 3

Don't Do Longer. Just Change the layout of recyclerview on alertdialog click. If you want to use grid layout than change it to the grid layout, LinearLayout and set adapter.notifydatasetchanged, And if you want to change the layout of recyclerview Adapter row than Add a parameterized constructor to the adapter of recyclerview.After that Read the parameters and set views according to that.like this

 public CategoryRecyclerview(List<MainCategory> mainCategories, Context context, FragmentManager fragmentManager,String layouttype) {
    this.context = context;
    layouttype= this.layouttype;}

and in the oncreateviewholder put this

 if(layouttype.equals("GRID")){
        View view = inflater.inflate(R.layout.grid, viewGroup, false);
        CategoryRecyclerview.Myviewholder viewHolder = new CategoryRecyclerview.Myviewholder(view);
        holders.add(viewHolder);
        return viewHolder;
    }

after that notifydatasetchanged.

Answer 4

No need to use multiple Recyclerview for this

You can achieve this using single Recyclerview with Multiple viewType

When you want to change the layout of Recyclerview just change the LayoutManager and viewType of your Recyclerview it will work

SAMPLE CODE

Try this way

First Create a Three layout for your Multiple viewType

grid_layout

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="150dp"
    android:layout_height="150dp"
    app:cardElevation="10dp"
    app:cardUseCompatPadding="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <ImageView
            android:layout_width="match_parent"
            android:layout_height="150dp"
            android:adjustViewBounds="true"
            android:contentDescription="@string/app_name"
            android:scaleType="centerCrop"
            android:src="@drawable/dishu" />

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            android:background="#6a000000"
            android:gravity="center"
            android:padding="10dp"
            android:text="dummy text"
            android:textColor="@android:color/white" />
    </RelativeLayout>

</android.support.v7.widget.CardView>

cardlist_layout

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