If you want to share 2 data from the first to second activity then use this method

for sharing intent

createButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            // Checks if there are empty fields
            if (isEmpty(etRecipeName, etDuration, etIngredient, etDesc) == false) {
                Toast.makeText(MainActivity.this, "There are empty fields. Please fill up all fields",
                        Toast.LENGTH_SHORT).show();
            }
            // Create the recipe
            else {
                createRecipe(etRecipeName, etDuration, etIngredient, etDesc);
                Toast.makeText(MainActivity.this, "Recipe Created", Toast.LENGTH_SHORT).show();

                Intent changePage = new Intent(MainActivity.this, afterCancel.class); // is this afterCancel.class your recipe activity?
                changePage.putExtra("first", firstData); // put here first data
                changePage.putExtra("second", secondData); // put here second data or string
                startActivity(changePage);
            }
        }
    });

for getting these data in afterCancel.java

String yourFirstData = getIntent().getStringExtra("first");
String yourSecondData = getIntent().getStringExtra("second");
Toast.makeText(this, yourFirstData, Toast.LENGTH_SHORT).show();
Toast.makeText(this, yourSecondData, Toast.LENGTH_SHORT).show();

code for cancel button

cancelButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            finish(); // use this.
        }
    });

Hope this helps

So basically, I have 2 buttons: Cancel, and Create Recipe. Clicking both would take me back to my home page.

“Create Recipe” requires some EditTexts beforehand to be filled before moving to the homepage and “Cancel”

“Cancel” works fine. But “Create Recipe” crashes the emulator

Below are my codes

// createRecipe button onClickListener
    Button createButton = findViewById(R.id.createButton);
    createButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            // Checks if there are empty fields
            if (isEmpty(etRecipeName, etDuration, etIngredient, etDesc) == false) {
                Toast.makeText(MainActivity.this, "There are empty fields. Please fill up all fields",
                        Toast.LENGTH_SHORT).show();
            }
            // Create the recipe
            else {
                createRecipe(etRecipeName, etDuration, etIngredient, etDesc);
                Toast.makeText(MainActivity.this, "Recipe Created", Toast.LENGTH_SHORT).show();
                Intent changePage = new Intent(MainActivity.this, afterCancel.class);
    startActivity(changePage);
            }
        }
    });

    // Cancel button onClickListener
    Button cancelButton = findViewById(R.id.cancelButton);
    cancelButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent changePage = new Intent(MainActivity.this, afterCancel.class);
    startActivity(changePage);
        }
    });

For my home page, its just a

this.getintent()
