RecyclerView with incremental search action.
Add the dependencies to your gradle file.
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
dependencies {

compile 'com.github.rei-m:filter-recyclerview:1.0.0'
}
Create Adapter extends FilterRecyclerAdapter.
Example.
class MainFilterRecyclerAdapter extends FilterRecyclerAdapter<ListItem> {
private LayoutInflater inflater;
MainFilterRecyclerAdapter(Context context) {
inflater = LayoutInflater.from(context);
}
@Override
public boolean filterByConstraint(@NonNull ListItem item, @NotNull String constraint) {
// SetUp constraint of filter.
String lowerName = item.getName().toLowerCase();
String lowerConstraint = constraint.trim().toLowerCase();
return lowerName.contains(lowerConstraint);
}
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return new ItemViewHolder(inflater.inflate(R.layout.item_row, parent, false));
}
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
((ItemViewHolder) holder).initialize(findItemByPosition(position));
}
private class ItemViewHolder extends RecyclerView.ViewHolder {
private TextView textName;
ItemViewHolder(View itemView) {
super(itemView);
textName = (TextView) itemView.findViewById(R.id.item_row_name);
}
private void initialize(ListItem listItem) {
textName.setText(listItem.getName() + " / " + listItem.getCategory());
}
}
}
Add FilterRecyclerView to your layout.
Example.
<android.support.design.widget.CoordinatorLayout android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Hello World!" />
</RelativeLayout>
<com.reim.android.filterrecyclerview.FilterRecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:filterHint="Input Name" />
</android.support.design.widget.CoordinatorLayout>
Set adapter to FilterRecyclerView and initialize list item.
filterRecyclerView = (FilterRecyclerView) findViewById(R.id.activity_main_filter_recycler_view);
filterRecyclerView.setAdapter(new MainFilterRecyclerAdapter(this));
List<ListItem> itemList = new ArrayList<>();
itemList.add(new ListItem("Sam", "Dog"));
itemList.add(new ListItem("Spot", "Cat"));
itemList.add(new ListItem("Pip", "Cat"));
itemList.add(new ListItem("Piper", "Dog"));
filterRecyclerView.initializeItemList(itemList);
