How to pass data from a selected item in a listview to another activity?

I have the following code. I have the data in the object o. There are three set of values in o (description, name, image url). I need these data to be initialized to a string and pass it to other activity using intent. How do I get each value in the object. Each list item has a image, item name and item description.

fp_list.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView parentView, View v, int position, long id) {
        // TODO Auto-generated method stub
        Toast.makeText(getApplicationContext(), "pos"+position, Toast.LENGTH_LONG).show();
        Object o = parentView.getItemAtPosition(position);
        Intent i = new Intent(FeaturedProductsActivity.this, ShowProduct.class);
    }
}

You can do it like this:

Intent intent = new Intent(YourActivity.this, NewActivity.class);
intent.putExtra("description", o.get(position).getdescription())
startActivity(descriptionIntent);

And in the second activity:

Intent descriptionIntent = getIntent();
String description = descriptionIntent.getExtras().getString("description");

simple way :

1-make a class which extend Application. 2-make an object of what you want to transfer. 3-make its set and get. 4-in onitemclick set the value. 5-get the value wherever you want.

Example:

1-make a class which extend Application. 2-make an object of what you want to transfer. 3-make its set and get.

public class App extends Application {
private static yourObject  obj;

public yourObject getobj() {
return obj;
}
public void setobj(yourObject obj) {
this.obj= obj;
}
}

in your class 

fp_list.setOnItemSelectedListener(new OnItemSelectedListener() {
    @Override
public void onItemSelected(AdapterView parentView, View v, int position, long id) {
    // TODO Auto-generated method stub

    yourObject  o =(yourObject) parentView.getItemAtPosition(position);
   App.setobj(o);
}

}

in any other where all over the application classes

//here you will get your object which you have set on item click
yourObject obj=App.getobj;

hope this help.

      Bundle bundle =new Bundle();

                bundle.putString("memId",o.getId() );
                Intent newIntent=new Intent(friendsOffrinends.this,RestaurantDetails.class);
                newIntent.putExtras(bundle);
                startActivityForResult(newIntent, 0);

When you have data you can use Bundle or you can directly attach data with Intent e.g. in.putExtra(...).

Better thing is to make you Custom Object Parcelable

the Other option is to pass these values one by one as:

Intent i=new Intent(FeaturedProductsActivity.this,ShowProduct.class);
i.putString("desc", o.getDescription());
i.putString("name", o.getName());
// rest of your values

ang get these values in ShowProduct Activity as:

Intent in = this.getIntent();
String name = in.getStringExtra("name");
String desc = in.getStringExtra("desc");
//rest of you values

You can't pass object from One activity to another using Intent. Yo have to use Parcelable interface . see this.
