Passing ArrayList from ActivityA to ActivityB

Question

I am making the following app for my school assignment. It is a simple Pizza app, which asks the user to select which topping they would like on their pizza. I ask the user to select the toppings they want by check-boxes. Once the user selects the toppings and clicks the "submit" button, it should open up a new activity and in this new activity it should display what the user had selected from the previous activity.

In other words:

user checks of -> Onions and Olives
then user clicks -> Submit
then new activity opens up, and displays what user selected

Here is my code for first activity called TanavActivityAd1 and my second activity called TanavActivityOrder

MY CODE: (TanavActivityAd1)(FirstActivity)

        }
    }

    public void finalSubmit(View view){

       String final_display = ""; //null value

        for(int i=0;i<topping.size();i++){

            String checked = topping.get(i).toString();
            final_display = final_display + checked +"\n" ;

        }
        final_text.setText("Toppings:\n" + final_display);

    }
}

Now how do i pass my array into new activity? I want to display what the user has selected in firstActivity to a new activity.

Pleaseeeee Help!

To pass ArrayList to another Activity:

Intent i = new Intent(TanavActivityAd1.this,TanavActivityOrder.class);
i.putExtra("Choice", topping);
startActivity(i);

get Arraylist in another Activity:

ArrayList<String> toppings = (ArrayList<String>) getIntent().getSerializableExtra("Choice");


for(int i=0;i<toppings.size();i++) {
    String s[]= toppings.get(i);
    for(int iv=0;iv<s.length;iv++)
    Log.i("..............:",""+s[iv]);
}

yes .you put this code in oncreate method @user5425093 – Damini Mehra Oct 05 '16 at 04:51
Okay, when i run the code on my app, it crashes my app. I put the code that passes the array in my submit button. Was that the right place to put it? – Mr.Tanav Oct 05 '16 at 04:58
you take checkbox in xml layout @user5425093 – Damini Mehra Oct 05 '16 at 05:01

Why do you have a String array inside of a list? – OneCricketeer Oct 05 '16 at 05:15

@DaminiMehra second activity – Mr.Tanav Oct 05 '16 at 05:39
@user5425093 please put debug at ArrayList toppings = (ArrayList) getIntent().getSerializableExtra("Choice"); and check you get data here – Damini Mehra Oct 05 '16 at 05:44
it doesnt even let me compile the program. it says there is something wrong with "String s[] = toppings.get(i);" gives me the above error.. – Mr.Tanav Oct 05 '16 at 05:57
@user5425093 plz comment this code for(int i=0;i – Damini Mehra Oct 05 '16 at 05:58
@user5425093 print log for arraylist – Damini Mehra Oct 05 '16 at 05:58
i ran the debugger, but it did not save the values.. how do i print the log for array list? – Mr.Tanav Oct 05 '16 at 06:35
@user5425093 Log.i("arlist"toppings.toString()); try this .let me know – Damini Mehra Oct 05 '16 at 06:37
nope, gave me error: `)` expected ... illegal start of expression .... `;` expected. :( – Mr.Tanav Oct 05 '16 at 06:51
check this: Log.i("arlist",toppings.toString()); – Damini Mehra Oct 05 '16 at 06:56
okay nvm i fixed it.. it works and it passes the variable. when i put a breakpoint at `Log.i("arlist",toppings.toString());` it tells me the size of the array is 2. and it makes sense, because I selected two toppings before clicking submit – Mr.Tanav Oct 05 '16 at 06:56
@user5425093 ok now take your data from arraylist and this ans help to you then accept the answer – Damini Mehra Oct 05 '16 at 06:57
@DaminiMehra u are totally awesome! thanks for everything! but how to display it? and can you explain to me what `Log.i("arlist",toppings.toString());` does. Thank you! – Mr.Tanav Oct 05 '16 at 07:02
@user5425093 for(int i=0;i – Damini Mehra Oct 05 '16 at 07:04
it doesnt work the prinitng. I get no errors, and it everything works perfectly fine, but it doesnt print the list. I really do appreciate your help thoe, and i appreciate all the time you put in this to help me out. – Mr.Tanav Oct 05 '16 at 07:13

Intent intent=new Intent(A.this,B.class);
intent.putStringArrayListExtra("LIST","your array list");

IN activity B get List by following way..

ArrayList<String>list=getIntent.getStringArrayListExtra("LIST")

You can do it like this,

Intent i = new Intent(A.this, B.class);
i.putStringArrayListExtra("key", stringArrayList);
startActivity(i);

on receiving activity (in this case B) you can receive list like below

ArrayList<String> list = getIntent().getStringArrayListExtra("key")

Happy Coding!

Since this is a school assignment I won't put any code but you can pass it through an intent extra. You'll create an intent, put your topping array list on the intent with a tag using

intent.putExtra(tag, topping)

and then call

startActivity(intent).

In the target actiivity of the intent you can call

getIntent().getSerializable(tag)

to return a list with the toppings contents. OK I lied, I put some code, good luck!

Passing ArrayList from ActivityA to ActivityB
