|
|
|
|
Unbound Drag & Drop is a versatile and user-friendly feature designed to enhance your Android
|
|
applications by enabling drag and drop functionality across multiple RecyclerViews. Unlike the
|
|
default behavior, which restricts drag and drop actions within a single RecyclerView, Unbound Drag &
|
|
Drop allows users to seamlessly move items between different RecyclerViews, providing a more
|
|
flexible and intuitive user experience.
|
|
|
|
## Features
|
|
|
|
- **Multi-RecyclerView Drag and Drop**: Easily drag and drop items between multiple RecyclerViews.
|
|
- **Customizable and Extensible**: Adapt the feature to fit your specific needs with customizable
|
|
options and extensible components.
|
|
- **Smooth and Intuitive User Experience**: Enhance the interactivity of your app with a
|
|
user-friendly drag and drop interface.
|
|
- **Easy Integration**: Quickly integrate Unbound Drag & Drop into your existing Android projects
|
|
with minimal setup.
|
|
|
|
## Installation
|
|
|
|
To include Unbound Drag & Drop in your project, add the following dependency to your build.gradle
|
|
file:
|
|
|
|
```kotlin
|
|
implementation("dev.adriankuta:unbound-drag-drop:0.1.0")
|
|
```
|
|
|
|
## Usage
|
|
|
|
### Setup
|
|
|
|
#### Step 1: Implement the Callback
|
|
|
|
Create a class that extends `DragDropHelper.Callback` to handle drag and drop events.
|
|
|
|
```kotlin
|
|
class MyDragDropCallback : DragDropHelper.Callback() {
|
|
override fun onMove(
|
|
recyclerView: RecyclerView,
|
|
viewHolder: RecyclerView.ViewHolder,
|
|
targetRecyclerView: RecyclerView,
|
|
targetViewHolder: RecyclerView.ViewHolder?
|
|
): Boolean {
|
|
// Handle the move logic here
|
|
return true
|
|
}
|
|
|
|
override fun onMoved(
|
|
recyclerView: RecyclerView,
|
|
viewHolder: RecyclerView.ViewHolder,
|
|
targetRecyclerView: RecyclerView,
|
|
targetViewHolder: RecyclerView.ViewHolder?
|
|
) {
|
|
// Handle post-move logic here
|
|
}
|
|
}
|
|
```
|
|
|
|
#### Step 2: Attach `DragDropHelper` to `RecyclerView`
|
|
|
|
In your Activity or Fragment, attach DragDropHelper to your RecyclerView.
|
|
|
|
```kotlin
|
|
val recyclerView: RecyclerView = findViewById(R.id.recycler_view)
|
|
val dragDropHelper = DragDropHelper(MyDragDropCallback())
|
|
dragDropHelper.attachToRecyclerView(recyclerView)
|
|
```
|
|
|
|
#
|
|
### Step 3: Enable long click
|
|
|
|
Dragging is enabled only for views with long click enabled. To allow dragging and dropping of `RecyclerView` items, you need to set `isLongClickable` to `true` for each RecyclerView item.
|
|
|
|
```kotlin
|
|
viewHolder.itemView.isLongClickable = true
|
|
|
|
```
|
