Passing Hashmap elements to another activity?

Question

Java

I implemented the method of adding elements to the listview through the HashMap, made it so that when you click on the element, another activity opens, how now to transfer the value contained in the HashMape to the new activity?

flat = new ArrayList<HashMap<String,Object>>();      
    HashMap<String, Object> hm;

    hm = new HashMap<String, Object>();
    hm.put(id, "S 5");
    hm.put(name, " Название1");                 
    hm.put(clas, " Класс:");        
    hm.put(view, " инф");
    hm.put(price, " 500  ");
    hm.put(img, R.drawable.kras40_main);

    flat.add(hm);                            

    hm = new HashMap<String, Object>();
    hm.put(name, " Название2");
    hm.put(clas, " Класс:");
    hm.put(img, R.drawable.lebed64_main);

    flat.add(hm);

In Java, it's generally not customary to store data in this way. You need to make a class that will have all these fields, this class can also implement the Parcelable interface, then you can push it into Intent.putExtra(), start the activity, pull it out using Intent.getExtras().getParcelable() and get profit. There are other ways, but you seem to need to master this one first.
