RecyclerViewSwipeDecorator

A simple utility class to add a background, an icon and a label to a RecyclerView item while swiping it left or right.

How do I get set up?

Get it via Gradle

implementation 'it.xabaras.android:recyclerview-swipedecorator:1.4'

or Maven

<dependency>
  <groupId>it.xabaras.android</groupId>
  <artifactId>recyclerview-swipedecorator</artifactId>
  <version>1.4</version>
  <type>pom</type>
</dependency>

In version 1.3 RecyclerViewSwipeDecorator migrated to AndroidX

Usage

Here is a non-comprehensive guide to RecyclerViewSwipeDecorator for any further information you can reference the library javadoc, the sources and/or the sample app sources.

Create an ItemTouchHelper.SimpleCallback, instantiate an ItemTouchHelper with this callback and attach it to your RecyclerView

ItemTouchHelper.SimpleCallback callback = new ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.RIGHT | ItemTouchHelper.LEFT) {
    @Override
    public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
        return false;
    }

    @Override
    public void onSwiped(RecyclerView.ViewHolder viewHolder, int direction) {
        // Take action for the swiped item
    }
};
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(callback);
itemTouchHelper.attachToRecyclerView(recyclerView);

Override the onChildDrawn method of your SimpleCallback object

@Override
public void onChildDraw (Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder,float dX, float dY,int actionState, boolean isCurrentlyActive){
    super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
}

Create a RecyclerViewSwipeDecorator using the RecyclerViewSwipeDecoratorBuilder and call the decorate() method

public void onChildDraw (Canvas c, RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder,float dX, float dY,int actionState, boolean isCurrentlyActive){

    new RecyclerViewSwipeDecorator.Builder(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive)
            .addBackgroundColor(ContextCompat.getColor(MainActivity.this, R.color.my_background))
            .addActionIcon(R.drawable.my_icon)
            .create()
            .decorate();
            
    super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
}
