RecyclerView example in Sketchware

 This post describes a sample project which uses RecyclerView to display a list of images and texts in Sketchware.

1. Create a new project in Sketchware.

2. In main.xml add a Linear linear2 for displaying the RecyclerView.

3. Create a CustomView custom_item.xml. In this add a Linear linear1, an ImageView c_imageview1, and a TextView c_textview1.

4. Add images using image manager in Sketchware.

5. Switch On AppCompat and Design.

6. Create a More block extra. In this block put code given below. This code creates a class MyImage, which can be constructed with a String and an int variable. The String variable will be used for setting title and int variable for setting image resource id.


public class MyImage {

private String mTitle;

private int mImage;

public MyImage(String title, int imageId) {

mTitle = title;

mImage = imageId;


public String getTitle(){

return mTitle;


public int getImage(){

return mImage;




7. Create another More block adapter, and put following codes in it.

// This code defines a class CategorylistAdapter which can be used as an adapter for RecyclerView.


public class CategorylistAdapter extends androidx.recyclerview.widget.RecyclerView.Adapter<CategorylistAdapter.MyViewHolder>{

Context context;

ArrayList<MyImage> maplist;

// Constructor for the adapter.

public CategorylistAdapter(ArrayList<MyImage> list, Context context){

this.maplist = list;

this.context = context;


// onCreateViewHolder method. Uses LayoutInflater to create View from the CustomView. The View will act as a ViewHolder.



public CategorylistAdapter.MyViewHolder onCreateViewHolder(@androidx.annotation.NonNull ViewGroup viewGroup, int i) {

View view= LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.custom_item, viewGroup, false);

return new CategorylistAdapter.MyViewHolder(view);


// onBindViewHolder method. Here we set the text of TextView text and image of ImageView img, by getting items at respective positions of the list. Here we can also set OnClickListeners for the Views.


public void onBindViewHolder(@androidx.annotation.NonNull final CategorylistAdapter.MyViewHolder myViewHolder, final int i) {




myViewHolder.linear1.setOnClickListener(new View.OnClickListener() {


public void onClick(View v){





// getItemCount() method. It gets the number of items in the list.


public int getItemCount() {

return maplist.size();


// Define MyViewHolder class. Here we define the Linear linear1, ImageView img and TextView text using the ids in Custom view.

class MyViewHolder extends androidx.recyclerview.widget.RecyclerView.ViewHolder{

public LinearLayout linear1;

public TextView text;

public ImageView img;

public MyViewHolder(@androidx.annotation.NonNull View itemView) {


linear1= itemView.findViewById(;

text= itemView.findViewById(;

img= itemView.findViewById(;





8. In onCreate use following codes.

// Create an ArrayList for MyImage with name mylist and add items to it.

ArrayList<MyImage> mylist = new ArrayList<MyImage>();

mylist.add(new MyImage("image 1", R.drawable.ic_image_1));

mylist.add(new MyImage("image 2", R.drawable.ic_image_2));

mylist.add(new MyImage("image 3", R.drawable.ic_image_3));

mylist.add(new MyImage("image 4", R.drawable.ic_image_4));

mylist.add(new MyImage("image 5", R.drawable.ic_image_5));

mylist.add(new MyImage("image 6", R.drawable.ic_image_6));

mylist.add(new MyImage("image 7", R.drawable.ic_image_7));

mylist.add(new MyImage("image 8", R.drawable.ic_image_8));

mylist.add(new MyImage("image 9", R.drawable.ic_image_9));

mylist.add(new MyImage("image 10", R.drawable.ic_image_10));

mylist.add(new MyImage("image 11", R.drawable.ic_image_11));

mylist.add(new MyImage("image 12", R.drawable.ic_image_12));

// Create a RecyclerView

androidx.recyclerview.widget.RecyclerView recyclerView = new androidx.recyclerview.widget.RecyclerView(this);

// Create a CategorylistAdapter adapter1 for displaying mylist.

CategorylistAdapter adapter1=new CategorylistAdapter(mylist, getApplicationContext());

// Set LayoutManager for RecyclerView. It can be set to display the RecyclerView as HORIZONTAL or VERTICAL.

recyclerView.setLayoutManager(new androidx.recyclerview.widget.LinearLayoutManager(getApplicationContext(), androidx.recyclerview.widget.LinearLayoutManager.HORIZONTAL, false));

// Set adapter1 as adapter of RecyclerView.


// Add RecyclerView to linear2.


9. Save and run the project.

  1. Log in is not working on sketchware ... It always says An error has occurred. SSL handshake time out

  2. Can we use this code in sketchware 3.9.11?

  3. Can you create a tutorial for how to create a ListView that can be rearranged using drag and drop? That would be very helpful.

  4. Nice blog . I have also been making tutorials related to Sketchware. In my Sketchware Interface video I have explaines each and every part of the Sketchware app itself. Do check my channel to learn more about sketchware.
