Recycler-swipe-drag
This library provides long press drag and swipe for recycler view items, based on the awesome explanation by Paul Burk & implemented in kotlin, video demo can be seen here
How to use
Include the library
Add the following lines in your app level dependencies
dependencies {
compile 'me.rishabhkhanna:RecyclerviewSwipeDrag:1.3.1'
}
NOTE: If you get errors regarding conflicting versions of Android Support Library (Manifest merger error), exclude the transitive dependency when including my library
dependencies {
compile ('me.rishabhkhanna:RecyclerviewSwipeDrag:1.3.1') {
exclude group: 'com.android.support', module: 'recyclerview-v7'
}
}
Usage
To use Recyclerview Swipe and Drag in your project, add the following lines and attach ItemTouchHelper
with your Recyclerview
object
RecyclerHelper touchHelper = new RecyclerHelper<T>(dataArrayList, (RecyclerView.Adapter) recyclerAdapter);
touchHelper.setRecyclerItemDragEnabled(true);
touchHelper.setRecyclerItemSwipeEnabled(true);
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(touchHelper);
itemTouchHelper.attachToRecyclerView(recyclerView);
- here T is the generic, pass your arrayList model class here like String, Integer or Students
- you have to pass the data array list and your recyclerview adapter to
RecyclerHelper
constructor - you have to cast your Recyclerview custom adapter in
Recyclerview.Adapter
, while passing it in RecyclerHelper - you can select if you want to enable your recycler view to have dragging items or swiping items or both , you can do this by passing boolean, in
touchHelper.setRecyclerItemDragEnabled(true);
ortouchHelper.setRecyclerItemSwipeEnabled(true);
, default is false for both. - if you want to do some tasks like storing the list in db or sending a network request after swiping or dragging the recyclerview item then you can this with these 2 callbacks
// callback for recyclerview item dragged from one position to other
touchHelper.setOnDragItemListener(new OnDragListener() {
@Override
public void onDragItemListener(int fromPosition, int toPosition) {
Log.d(TAG, "onDragItemListener: callback after dragging recycler view item");
}
});
// callback for recyclerview item swiped left or right
touchHelper.setOnSwipeItemListener(new OnSwipeListener() {
@Override
public void onSwipeItemListener() {
Log.d(TAG, "onSwipeItemListener: callback after swiping recycler view item");
}
});
- you can also use this library in fluid api like this
RecyclerHelper touchHelper = new RecyclerHelper<String>(dataArrayList, (RecyclerView.Adapter) recyclerAdapter);
touchHelper
.setRecyclerItemDragEnabled(true)
.setRecyclerItemSwipeEnabled(true)
.setOnDragItemListener(new OnDragListener() {
@Override
public void onDragItemListener(int fromPosition, int toPosition) {
Log.d(TAG, "onDragItemListener: callback after dragging recycler view item");
}
})
.setOnSwipeItemListener(new OnSwipeListener() {
@Override
public void onSwipeItemListener() {
Log.d(TAG, "onSwipeItemListener: callback after swiping recycler view item");
}
});
Example
- example usage of library with model class for arraylist as Students
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
ArrayList<Students> dataArrayList = new ArrayList();
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(recyclerAdapter);
// Library addition from here
RecyclerHelper touchHelper = new RecyclerHelper<Students>(dataArrayList, (RecyclerView.Adapter) recyclerAdapter);
touchHelper.setRecyclerItemDragEnabled(true).setOnDragItemListener(new OnDragListener() {
@Override
public void onDragItemListener(int fromPosition, int toPosition) {
Log.d(TAG, "onDragItemListener: callback after dragging recycler view item");
}
});
touchHelper.setRecyclerItemSwipeEnabled(true).setOnSwipeItemListener(new OnSwipeListener() {
@Override
public void onSwipeItemListener() {
Log.d(TAG, "onSwipeItemListener: callback after swiping recycler view item");
}
});
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(touchHelper);
itemTouchHelper.attachToRecyclerView(recyclerView);
