RecyclerAdapters
Introduction
RecyclerAdapters provides you a very simple way for implement RecyclerView.Adapter class in your projects. With this library you can implement Adapter in a few line.
Get started
dependencies {
compile 'com.github.alex-michenko:recycleradapters:0.3.0'
}
How to use
1.Create DataHolder
Create class-wrapper that will hold data for adapter:
public class PersonDH implements RecyclerDH {
public boolean isFavourite;
public int countStars;
public String name;
public String headerName;
public PersonDH(String name, boolean isFavourite) {
this.name = name;
this.isFavourite = isFavourite;
if (isFavourite)
countStars = new Random().nextInt(4) + 1;
}
public PersonDH(String headerName) {
this.headerName = headerName;
}
}
2. Create ViewHolder
Create ViewHolder class and set generic parameter as created DataHolder:
public class PersonVH extends RecyclerVH<PersonDH> {
private TextView tvNamePerson;
public PersonVH(View itemView) {
super(itemView);
tvNamePerson = findView(R.id.tvNamePerson);
}
@Override
public void setListeners(final OnCardClickListener listener) {
tvNamePerson.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
listener.onClick(view, getAdapterPosition(), getItemViewType());
}
}
);
}
@Override
public void bindData(PersonDH data) {
tvNamePerson.setText(data.name);
}
}
Method setListeners() is called if OnCardClickListener was setted for your adapter
If you adapter has several viewTypes then create suitable ViewHolders:
public class FavouriteVH extends RecyclerVH<PersonDH> {
//.....
}
public class HeaderVH extends RecyclerVH<PersonDH> {
//.....
}
3. Create adapter
Create an adapter and implement methods for cteating ViewHolders
public class PersonAdapter extends RecyclerAdapter<PersonDH> {
private static final int HEADER = 1;
private static final int PERSON = 11;
private static final int FAVOURITE = 0;
@NonNull
@Override
protected RecyclerVH<PersonDH> createVH(View view, int viewType) {
switch (viewType) {
case PERSON:
return new PersonVH(view);
case HEADER:
return new HeaderVH(view);
default:
return new FavouriteVH(view);
}
}
@Override
protected int getLayoutRes(int viewType) {
switch (viewType) {
case PERSON:
return R.layout.item_person;
case HEADER:
return R.layout.item_header;
default:
return R.layout.item_favourite;
}
}
@Override
public int getItemViewType(int position) {
PersonDH dh = getItem(position);
if (dh.headerName != null) {
return HEADER;
}
else {
return dh.isFavourite ? FAVOURITE : PERSON;
}
}
}
4. Use adapter
Init your adapter and set in RecyclerView :
rvSimpleList = (RecyclerView) view.findViewById(R.id.rvTypedList);
rvSimpleList.setLayoutManager(new LinearLayoutManager(getContext()));
adapter = new PersonAdapter();
adapter.setOnCardClickListener(new OnCardClickListener() {
@Override
public void onClick(View view, int position, int viewType) {
//do something
}
}
);
rvSimpleList.setAdapter(adapter);
