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);
}
}
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.

Bundle bundle =new Bundle();
bundle.putString("memId",o.getId() );
Intent newIntent=new Intent(friendsOffrinends.this,RestaurantDetails.class);
newIntent.putExtras(bundle);
startActivityForResult(newIntent, 0);
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.
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");
当你有数据时,你可以使用 Bundle 或者你可以直接使用 Intent 附加数据,例如in.putExtra(...)
