Adapter
A quick adapter library for RecyclerView, GridView, ListView, ViewPager, Spinner. It abstracts the boilerplate of item view types, item layouts, viewholders, span sizes , and more, in order to simplify building complex screens with multiple view types. 1.x is deprecated and please upgrade to 2.x
Features
- Support DataBinding.
- Multiple view types without any ViewHolder
- Simple, flexible
Setup
compile 'com.github.thepacific:adapter:{
lastestVersion
}
'Proguard
-keep class android.databinding.DataBindingUtil {
public static *;
}
Item
Extend SimpleItem or SimpleRecylcerItem. Optionally, you may implement Item or RecylcerItem
public class YourItem extends SimpleItem {
String name;
String description;
String imageUrl;
@Override
public int getLayout() {
return R.layout.item_cartoon;
}
@Override
public void bind(ViewHolder holder) {
//bind data
DefaultBinding binding = holder.binding();
binding.setText(R.id.text_name, name);
binding.setText(R.id.text_desc, description);
//attach listeners or load image
holder.attachImageLoader(R.id.img_header);
holder.attachOnClickListener(R.id.layout_root);
//holder.attachOnLongClickListener(viewId);
//holder.attachOnTouchListener(viewId);
//holder.attachOnCheckedChangeListener(viewId);
}
//You may override any other method
}
DataBinding
public class YourItem extends SimpleItem {
@Override
public void bind(ViewHolder holder) {
//Without DataBinding, just use DefaultBinding
DefaultBinding binding = holder.binding();
//With DataBinding, use layout generated Binding instead of DefaultBinding
LayoutGeneratedBinding binding = holder.binding();
}
}
Listeners
Set OnClickListener, OnLongClickListener, OnTouchListener, OnCheckedChangeListener and ImageLoader:
RecyclerAdapter adapter = new RecyclerAdapter();
//RecyclerView AbsAdapter adapter = new AbsAdapter(int viewTypeCount);
//GridView, ListView, Spinner PagerAdapter2 adapter2 =new PagerAdapter2();
//ViewPager //set listeners or ImageLoader adapter.setOnClickListener(OnClickListener listener);
adapter.setOnTouchListener(OnTouchListener listener);
adapter.setOnLongClickListener(OnLongClickListener listener);
adapter.setOnCheckedChangeListener(OnCheckedChangeListener listener);
adapter.setImageLoader(ImageLoader imageLoader);
adapter.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//get ViewHolder
ViewHolder holder = AdapterUtil.getHolder(v);
//find view in ItemView
TextView textName = AdapterUtil.findView(holder.itemView, R.id.text_name);
//get Item
Item item = holder.getItem();
//get adapter data size
int size = holder.getSize();
holder.isFirstItem();
holder.isLastItem();
//for ListView,GridView, ViewPager, Spinner and RecyclerView
int position = holder.getCurrentPosition();
//only for RecyclerView
int position = holder.getAdapterPosition();
}
}
);
adapter.setImageLoader((imageView, holder) -> {
YourItem item = holder.getItem();
Glide.with(this)
.load(item.imageUrl())
.fitCenter()
.into(imageView);
}
);
Others
adapter.setOnDataSetChanged(OnDataSetChanged onDataSetChanged);
//data set changed callback , it's useful to show or hide empty view public interface OnDataSetChanged {
//called when data size is 0
void onEmptyData();
//called when data size larger than 0
void onHasData();
}
