Sau khi Google mình tìm thấy thư viện AndroidSwipeLayout có hỗ trợ các hiệu ứng khá đẹp. Thư viện khi kết hợp với RecycleView sẽ tạo ra nhiều option cho người dùng chọn khi swipe trái/phải màn hình.
Bài viết này mình sẽ hướng dẫn các bạn thêm thư viện AndroidSwipeLayout kết hợp với RecyclerView vào project.
Các bước thực hiện như sau:
Bước 1: Add thư viện
Mở file gradle và thêm dòng sau.
compile 'com.daimajia.swipelayout:library:1.2.0@aar'Bước 2: Định nghĩa item của listview
Trong phần res/layout, thêm file swipe_row_item.xml dùng để định nghĩa một thành phần của Listview.
<?xml version="1.0" encoding="utf-8" ?> <com.daimajia.swipe.SwipeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:swipe="http://schemas.android.com/apk/res-auto" android:id="@+id/swipe" android:layout_width="match_parent" android:layout_height="73dp" swipe:leftEdgeSwipeOffset="0dp" swipe:rightEdgeSwipeOffset="0dp"> <!--Bottom View For Right to Left--> <LinearLayout android:id="@+id/bottom_wrapper" android:layout_width="240dp" android:layout_height="match_parent" android:weightSum="3"> <TextView android:id="@+id/tvEdit" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="#0076a5" android:gravity="center" android:text="Edit" android:textColor="#fff" /> <TextView android:id="@+id/tvShare" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="#003c54" android:gravity="center" android:text="Share" android:textColor="#fff" /> <TextView android:id="@+id/tvDelete" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="#0076a5" android:gravity="center" android:text="Delete" android:textColor="#fff" /> </LinearLayout> <!-- Another Bottom View For Left to Right --> <LinearLayout android:id="@+id/bottom_wrapper1" android:layout_width="80dp" android:layout_height="match_parent" android:weightSum="1"> <ImageButton android:id="@+id/btnLocation" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1" android:background="@null" android:gravity="center" android:src="@drawable/location_icon" /> </LinearLayout> <!-- Top View, Row itemView of RecyclerView --> <LinearLayout android:layout_width="match_parent" android:layout_height="73dp" android:background="?android:selectableItemBackground" android:orientation="horizontal"> <RelativeLayout android:layout_width="85dp" android:layout_height="match_parent" android:paddingLeft="18dp" android:paddingRight="18dp" android:paddingTop="8dp" android:paddingBottom="8dp"> <ImageView android:layout_width="match_parent" android:layout_height="match_parent" android:src="@drawable/contact_default"/> </RelativeLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:paddingRight="18dp" android:paddingTop="15dp" android:paddingBottom="15dp"> > <!--contact name layout--> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/tvName" android:layout_width="200dp" android:layout_height="20dp" android:text="Name" android:textColor="@android:color/black" android:textSize="16sp" /> <TextView android:id="@+id/tvDeliveryStatus" android:layout_width="match_parent" android:layout_height="20dp" android:gravity="right" android:textAlignment="gravity" android:text="Sent"/> </LinearLayout> <!--message content--> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/tvEmailId" android:layout_width="200dp" android:layout_height="20dp" android:layout_below="@+id/tvName" android:text="Email Id" android:textColor="@android:color/black" android:textSize="12sp" /> <ImageView android:layout_width="match_parent" android:layout_height="match_parent" android:adjustViewBounds="true" android:scaleType="fitEnd" android:src="@drawable/facebook_icon"/> </LinearLayout> </LinearLayout> </LinearLayout> </com.daimajia.swipe.SwipeLayout>Bước 3: Tạo lớp Student.
package com.blogspot.simplecodecjava.swiperecycleview; import java.io.Serializable; public class Student implements Serializable { private static final long serialVersionUID = 1L; private String name; private String emailId; public Student() { } public Student(String name, String emailId) { this.name = name; this.emailId = emailId; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getEmailId() { return emailId; } public void setEmailId(String emailId) { this.emailId = emailId; } }Bước 4: Tạo lớp SwipeRecyclerViewAdapter kế thừa từ RecyclerSwipeAdapter.

} }); viewHolder.tvDelete.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { mItemManger.removeShownLayouts(viewHolder.swipeLayout); studentList.remove(position); notifyItemRemoved(position); notifyItemRangeChanged(position, studentList.size()); mItemManger.closeAllItems(); Toast.makeText(view.getContext(), "Deleted " + viewHolder.tvName.getText().toString(), Toast.LENGTH_SHORT).show(); } }); // mItemManger is member in RecyclerSwipeAdapter Class mItemManger.bindView(viewHolder.itemView, position); } @Override public int getItemCount() { return studentList.size(); } @Override public int getSwipeLayoutResourceId(int position) { return R.id.swipe; } // ViewHolder Class public static class SimpleViewHolder extends RecyclerView.ViewHolder { SwipeLayout swipeLayout; TextView tvName; TextView tvEmailId; TextView tvDelete; TextView tvEdit; TextView tvShare; ImageButton btnLocation; public SimpleViewHolder(View itemView) { super(itemView); swipeLayout = (SwipeLayout) itemView.findViewById(R.id.swipe); tvName = (TextView) itemView.findViewById(R.id.tvName); tvEmailId = (TextView) itemView.findViewById(R.id.tvEmailId); tvDelete = (TextView) itemView.findViewById(R.id.tvDelete); tvEdit = (TextView) itemView.findViewById(R.id.tvEdit); tvShare = (TextView) itemView.findViewById(R.id.tvShare); btnLocation = (ImageButton) itemView.findViewById(R.id.btnLocation); } } }Bước 5: Khai báo MainAtivity.
