Passing Data to a new Activity on a Button Click

Question

I am very new to Android Studio, and have found myself stuck in this concept. I am attempting to pass Price + Name data to a Cart activity upon a button press (Add to Cart).

After attempting intent methods, it seems that after pressing "Add to Cart", the cart is opened with the data, but the data is not saved in the new activity for more additions.

Right now I have the following:

 Button button = (Button) findViewById(R.id.addcart);
    button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            //How to pass information here
        }
    });

I am hoping to pass textView6 and textView7 to the cart activity. If possible, I would be interested in passing the image as well! Any start on this would be appreciated. Thank you!

To pass data trhoug activities you can use the same intent you use to open the new activity. You can set extras like this:

Intent i = new Intent(context, CartActivity.class);
i.putExtra("price", textView6.getText().toString());
i.putExtra("name", textView7.getText().toString());
startActivity(i);

And then in onCreate() of the just created activity you can retrieve this data getting the intent used to open this activity and getting its extras:

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);

   Intent data = getIntent();
   String price = data.getStringExtra("price");
   String name = data.getStringExtra("name");
}

Hope this help.
