|Related to : fragment - getView() method return NULL|
|The method of type Fragment must override or implement a supertype method|
Leave the configuration methods and their calls in the
FragmentActivity, and create an interface to get/set the index there
in the Fragment.
In the Fragment:
public class TopRatedFragment extends Fragment
public interface ISettings
public int getIndex();
public void setIndex(int index);
public View onCreateView(LayoutInflater inflater, ViewGro
|Fragment and factory method|
Static factory methods allow us to initialize and setup a new Fragment
without having to call its constructor and additional setter methods.
Providing static factory methods for your fragments is good practice
because it encapsulates and abstracts the steps required to setup the
object from the client.
|How to call async method inside a method which has return type?|
I don't like it much, because it involves code that calls an async
method synchronously. But the following should work:
class AssociationUriMapper : UriMapperBase

You need to measure your ImageView and then get the measuredWidth:
holder.photoPost = (ImageView)
|In order to fill the properties of an object, what is more effective, to send the object as parameter to a method or return it from the method?|
It largely depends on your use case. With the second variant, you
always create a new DataEntity object, while with the first variant,
users could reuse a single instance of that class.
If the DataEntity objects are rather short-lived, but a lot of them
will be created, the garbage collection might get busy cleaning up all
the unused objects with the second variant. With the first variant,
