## JomloRecyclerView
A detachable RecyclerView component.
Write single or multiple item (component) for the adapter, re-use it in another part. Every component act as a single entity inside the adapter.
## How To Use
### Import the file
```java
import id.web.setoelkahfi.jomlorecyclerview.Adapter;
import id.web.setoelkahfi.jomlorecyclerview.ItemInterface;
```
### Use it in activity
Create reference to the adapter, create the dataset, and hook them up together via dependency injection.
```java
public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private Adapter jomloAdapter;
private List> jomloDataSet = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
jomloAdapter = new Adapter(jomloDataSet);
recyclerView.setAdapter(jomloAdapter);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
for (int i=0; i < 20; i++) {
SimpleItem item = new SimpleItem("Simple Example", "Subtest");
jomloDataSet.add(item);
}
jomloAdapter.notifyDataSetChanged();
}
}
```
## The Files
### Adapter
Custom adapter to hold our items. Used it as adapter for regular RecyclerView.
```java
public class Adapter extends RecyclerView.Adapter {
private List> dataSet = null;
private int lastPosition;
public Adapter(List> dataSet) {
this.dataSet = dataSet;
}
public Adapter() {
this.dataSet = new ArrayList<>();
}
@Override
public int getItemViewType(int position) {
ItemInterface extends ViewHolder> item = dataSet.get(position);
return item.getTypeId();
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
for (ItemInterface extends ViewHolder> item : dataSet) {
if (item.getTypeId() == i)
return item.createViewHolder(viewGroup);
}
return null;
}
@Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
ItemInterface extends ViewHolder> item = dataSet.get(i);
item.populateViewHolder(viewHolder);
Log.d("JomloRecyclerView", "OnBindViewHolder("+i+"'");
//setAnimation(viewHolder.itemView, i);
}
@Override
public int getItemCount() {
return dataSet.size();
}
private void setAnimation(View viewToAnimate, int position)
{
if (position > lastPosition)
{
Animation animation = AnimationUtils.loadAnimation(viewToAnimate.getContext(), R.anim.slide_top_down);
viewToAnimate.startAnimation(animation);
lastPosition = position;
}
}
public void add(ItemInterface item) {
if (dataSet != null)
dataSet.add(item);
}
public void add(int index, ItemInterface item) {
if (dataSet != null)
dataSet.add(index, item);
}
public void remove(ItemInterface item) {
if (dataSet != null)
dataSet.remove(item);
}
public void remove(int index) {
if (dataSet != null)
dataSet.remove(index);
}
public void clear() {
if (dataSet != null)
dataSet.clear();
}
static class ViewHolder extends RecyclerView.ViewHolder {
public ViewHolder(View itemView) {
super(itemView);
}
}
}
```
### Item
Subclass this class to create your custom item. Add this item into dataSet in your adapter.
```java
public abstract class Item implements ItemInterface {
@Override
public int getTypeId() {
return this.getClass().hashCode();
}
@Override
public T createViewHolder(ViewGroup parent) {
View v = LayoutInflater.from(parent.getContext()).inflate(getViewId(), parent, false);
try {
String className = ((ParameterizedType)getClass().getGenericSuperclass()).getActualTypeArguments()[0].toString().split("\\s")[1];
return (T)Class.forName(className).getConstructor(this.getClass(), View.class).newInstance(this, v);
} catch (Exception e) {
throw new RuntimeException("Please create a ViewHolder accepting view as argument.");
}
}
@Override
public void populateViewHolder(Adapter.ViewHolder holder) {
onPopulateViewHolder((T) holder);
}
protected abstract int getViewId();
protected abstract void onPopulateViewHolder(T holder);
}
```
### Item interface
Interface for creating item object.
```java
interface ItemInterface {
int getTypeId();
T createViewHolder(ViewGroup parent);
void populateViewHolder(Adapter.ViewHolder holder);
}
```
