Android ListView with onClick items

Question

I\'m a new programmer and new in Android. I\'m using this example http://www.androidhive.info/2012/09/android-adding-search-functionality-to-listview/ and it works great.

Answer 1

for what kind of Hell implementing Parcelable ?

he is passing to adapter String[] so

• get item(String) at position
• create intent
• put it as extra
• start activity
• in activity get extra

to store product list you can use here HashMap (for example as STATIC object)

example class describing product:

public class Product {
    private String _name;
    private String _description;
    private int _id

    public Product(String name, String description,int id) {
        _name = name;
        _desctription = description;
        _id = id;
    }

    public String getName() {
        return _name;
    }

    public String getDescription() {
        return _description;
    }
}

Product dell = new Product("dell","this is dell",1);

HashMap _hashMap = new HashMap<>();
_hashMap.put(dell.getName(),dell);

then u pass to adapter set of keys as:

String[] productNames =  _hashMap.keySet().toArray(new String[_hashMap.size()]);

when in adapter u return view u set listener like this for example:

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {

     Context context = parent.getContext(); 

     String itemName = getItem(position)

     someView.setOnClikListener(new MyOnClickListener(context, itemName));

 }


 private class MyOnClickListener implements View.OnClickListener { 

     private  String _itemName; 
     private  Context _context

     public MyOnClickListener(Context context, String itemName) {
         _context = context;
         _itemName = itemName; 
     }

     @Override 
     public void onClick(View view) {
         //------listener onClick example method body ------
         Intent intent = new Intent(_context, SomeClassToHandleData.class);
         intent.putExtra(key_to_product_name,_itemName);
         _context.startActivity(intent);
     }
 }

then in other activity:

@Override 
public void onCreate(Bundle) {

    String productName = getIntent().getExtra(key_to_product_name);
    Product product = _hashMap.get(productName);

}

*key_to_product_name is a public static String to serve as key for extra

ps. sorry for typo i was in hurry :) ps2. this shoud give you a idea how to do it ps3. when i will have more time i I'll add a detailed description

MY COMMENT:

• DO NOT USE ANY SWITCH STATEMENT
• DO NOT CREATE SEPARATE ACTIVITIES FOR EACH PRODUCT ( U NEED ONLY ONE)
