Right now I have a funtional swipe left to delete in recyclerview with two layouts(foreground and background). I use itemtouchhelper in the code. However, I would like to have BOTH swipe left and swipe right showing different colors and icons, like in Google Inbox. How can I implement that?
What I want is:
swipe rightswipe left
what I have is:
only swipe right
the code is just the standard itemtouchhelper.simplecallback with 2 layouts in the xml. And I googled everywhere and only found single swipe option with single icon and single color
Use ItemTouchHelper to Implement the Gmail Like Feature
call the following function after setting the recyclerView
private fun initSwipe() {
val simpleItemTouchCallback = object : ItemTouchHelper.SimpleCallback(0, ItemTouchHelper.LEFT or ItemTouchHelper.RIGHT) {
override fun onMove(recyclerView: RecyclerView, viewHolder: RecyclerView.ViewHolder, target: RecyclerView.ViewHolder): Boolean {
return false
}
override fun onSwiped(viewHolder: RecyclerView.ViewHolder, direction: Int) {
val position = viewHolder.adapterPosition
if (direction == ItemTouchHelper.LEFT) {
//Logic to do when swipe left
} else {
//Logic to do when swipe right
}
}
override fun onChildDraw(c: Canvas, recyclerView: RecyclerView, viewHolder: RecyclerView.ViewHolder, dX: Float, dY: Float, actionState: Int, isCurrentlyActive: Boolean) {
val icon: Bitmap
if (actionState == ItemTouchHelper.ACTION_STATE_SWIPE) {
//Drawing for Swife Right
val itemView = viewHolder.itemView
val height = itemView.bottom.toFloat() - itemView.top.toFloat()
val width = height / 3
if (dX > 0) {
p.color = Color.parseColor("#2F2FD3")
val background = RectF(itemView.left.toFloat(), itemView.top.toFloat(), dX, itemView.bottom.toFloat())
c.drawRect(background, p)
icon = BitmapFactory.decodeResource(resources, R.drawable.ic_archive)
val icon_dest = RectF(itemView.left.toFloat() + width, itemView.top.toFloat() + width, itemView.left.toFloat() + 2 * width, itemView.bottom.toFloat() - width)
c.drawBitmap(icon, null, icon_dest, p)
} else {
//Drawing for Swife Left
p.color = Color.parseColor("#D32F2F")
val background = RectF(itemView.right.toFloat() + dX, itemView.top.toFloat(), itemView.right.toFloat(), itemView.bottom.toFloat())
c.drawRect(background, p)
icon = BitmapFactory.decodeResource(resources, R.drawable.ic_delete)
val icon_dest = RectF(itemView.right.toFloat() - 2 * width, itemView.top.toFloat() + width, itemView.right.toFloat() - width, itemView.bottom.toFloat() - width)
c.drawBitmap(icon, null, icon_dest, p)
}
}
super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive)
}
}
val itemTouchHelper = ItemTouchHelper(simpleItemTouchCallback)
itemTouchHelper.attachToRecyclerView(YOUR_RECYCLER_VIEW)
}
Where
Object p is an object of paint Paint p = new Paint()
Hope this may help you.
