Easiest Generic Recycler Adapter
Easiest way to use RecyclerView. Reduce boilerplate code! You don't need to write adapters for listing pages anymore!
You can check it out Demo Application here
How to Setup:
- Step 1. Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven {
url 'https://jitpack.io'
}
}
}
- Step 2. Add the dependency
dependencies {
compile 'com.github.burakeregar:EasiestGenericRecyclerAdapter:v1.5'
}
How to Use:
Create your ViewHolder class & extend GenericViewHolder
public class YourViewHolder extends GenericViewHolder {
private YourModel mItem;
public YourViewHolder(final View itemView) {
super(itemView);
}
public void bindData(final Object element) {
mItem = (YourModel) element;
// set whatever you want. for instance;
surname.setText(mItem.getSurname());
name.setText(mItem.getName());
}
}
In your activity/fragment class you can initialize adapter like below;
GenericRecyclerAdapter mAdapter; RecyclerView mMainRv;
mMainRv.setLayoutManager(new LinearLayoutManager(this));
//set your layout manager
mAdapter = new GenericAdapterBuilder()
.addModel(
R.layout.contact_row, //set your row's layout file
YourViewHolder.class, //set your view holder class
YourModel.class) // set your model class(If you use just String list, it can be just String.class)
.execute();
mMainRv.setAdapter(mAdapter);
If your list contains different row types, you can add them like below;
mAdapter = new GenericAdapterBuilder()
.addModel(
R.layout.contact_row,
YourViewHolder.class,
YourModel.class)
.addModel(
R.layout.second_row,
YourSecondViewHolder.class,
YourSecondModel.class)
.addModel(
R.layout.third_row,
YourThirdViewHolder.class,
YourThirdModel.class)
.execute();
Now you are ready to set your list!
Assume that you have
List<YourModel> mListor
List<Object> mListthen you can set your list like this.
mAdapter.setList(mList);
if you want to add new row(s) to your existing list, you can use addNewRows method. You can pass any object or object list to addNewRows method like below;
mAdapter.addNewRows(mList);
or
YourModel lItem; mAdapter.addNewRows(lItem);
You can use getItems method to get current items of the list;
List<YourModel> mList = mAdapter.getItems();
Using with Filter
If you want to use filter with your recyclerview for searching etc. you have to enable & set filter like below;
mAdapter = new GenericAdapterBuilder()
.addModel(
R.layout.contact_row,
YourViewHolder.class,
YourModel.class)
.setFilterEnabled() //important!
.execute();
mAdapter.setFilter(new SearchFilter(mAdapter));
Example search filter class;
public class SearchFilter extends Filter {
private GenericRecyclerAdapter mAdapter;
public SearchFilter(GenericRecyclerAdapter pAdapter) {
mAdapter = pAdapter;
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
final List<Object> list = mAdapter.mOriginalObjectList;
final ArrayList<Object> filteredList = new ArrayList<>();
String filterableString = "";
for (Object lModel : list) {
if (lModel instanceof YourModel) {
filterableString = ((YourModel) lModel).getValue();
}
if (filterableString.contains(constraint.toString())) {
filteredList.add(lModel);
}
}
results.values = filteredList;
results.count = filteredList.size();
return results;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
mAdapter.mObjectList = (List<Object>) results.values;
mAdapter.notifyDataSetChanged();
}
}
you can set & listen the result in your edittext's afterTextChanged method;
mAdapter.getFilter().filter(editable.toString(), new Filter.FilterListener() {
@Override
public void onFilterComplete(int pI) {
if (mAdapter.mObjectList == null || mAdapter.mObjectList.size() <= 0) {
//If the search key is deleted, set the original list
mAdapter.addItem(mAdapter.mOriginalObjectList);
}
}
}
);
