SwipeToAction

Download

An easy way to add a simple 'swipe-and-do-something' behavior to your RecyclerView items. Just like in Gmail or Inbox apps.

SwipeToAction Sample

Integration

The lib is available on Maven Central, you can find it with Gradle, please

dependencies {
    compile 'co.dift.ui.swipetoaction:library:1.1'
}

Usage

Check a demo project in the sample/ folder.

  1. The view you'll use for the items should have at least 3 children:
  • the one at the front (the last one or anyone with the tag=front)

  • the one to reveal when you swipe to left (before the front view or anyone with tag=reveal-left)

  • the one to reveal when you swipe to right (before the reveal-left view or anyone with tag=reveal-right)

     <!-- this view reveals when swipe right -->
     <RelativeLayout
        android:tag="reveal-right"
        android:background="@color/accent"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_centerVertical="true"
            android:layout_marginLeft="20dp"
            android:tint="@color/icons"
            android:src="@mipmap/ic_favorite_black_24dp"/>
     </RelativeLayout>
    
     <!-- this view reveals when swipe left -->
     <RelativeLayout
        android:tag="reveal-left"
        android:background="@color/primary"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_centerVertical="true"
            android:layout_marginRight="20dp"
            android:tint="@color/icons"
            android:src="@mipmap/ic_delete_black_24dp"/>
     </RelativeLayout>
    
     <!-- this is the item front view -->
     <RelativeLayout
        android:tag="front"
        android:background="@color/item_background"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:padding="@dimen/item_padding">
    
        <TextView
            android:id="@+id/title"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_toRightOf="@+id/image"
            android:singleLine="true"
            android:textSize="16dp"
            android:textStyle="bold" />
    
     </RelativeLayout>
  1. In the adapter for your RecyclerView create a ViewHolder that extends SwipeToAction.ViewHolder. For instance, in the sample project I have a list of books and my items are instances of a Book class, therefore, the ViewHolder inside the adapter looks like this:

       public class BookViewHolder extends SwipeToAction.ViewHolder<Book> {
         ...
         public BookViewHolder(View v) {
           super(v);
           ...
         }
       }

    Also, in the onBindViewHolder method remember to set the item data to the view holder instance

      @Override
      public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        Book item = items.get(position);
        BookViewHolder vh = (BookViewHolder) holder;
        vh.data = item;
    
        ...
    
      }
  2. Set the RecyclerView as usual to create a vertical list, set the previous adapter and instantiate SwipeToAction providing the recyclerView instance and a swipe listener SwipeToAction.SwipeListener<T>

      recyclerView = (RecyclerView) findViewById(R.id.recycler);
      LinearLayoutManager layoutManager = new LinearLayoutManager(this);
      recyclerView.setLayoutManager(layoutManager);
      recyclerView.setHasFixedSize(true);
    
      adapter = new BooksAdapter(this.books);
      recyclerView.setAdapter(adapter);
    
      swipeToAction = new SwipeToAction(recyclerView, new SwipeToAction.SwipeListener<Book>() {
        @Override
        public boolean swipeLeft(final Book itemData) {
            //do something
            return true; //true will move the front view to its starting position
        }
    
        @Override
        public boolean swipeRight(Book itemData) {
            //do something
            return true;
        }
    
        @Override
        public void onClick(Book itemData) {
            //do something
        }
    
        @Override
        public void onLongClick(Book itemData) {
            //do something
        }
      });
