## Panel Layout
Panel Layout is a UI library for Android that allows you to display a floating and resizable panel that can also snap to the edges.
Panel Layout makes use of [ConstraintLayout](https://developer.android.com/training/constraint-layout) to lay out panel with rest of the content.
This library is inspired by a good iOS UI framework: [PanelKit](https://github.com/louisdh/panelkit)
### Importing Panel Layout
[  ](https://bintray.com/wayfair/PanelLayout/PanelLayout/_latestVersion)
```kotlin
dependencies {
implementation("com.wayfair.panellayout:panellayout:<latest-version>")
}
```
**Note:** Panel Layout is currently in alpha and the public API it offers is __subject to heavy changes__.
### Panel Layout API
Define if the Panel Layout is visible
```kotlin
var panelVisible: Boolean
```
The command that put Panel Layout in one of the predefine Panel Positions.
Possible panel positions are: `LEFT_EDGE`, `RIGHT_EDGE`, `TOP_EDGE`, `BOTTOM_EDGE`, `NO_EDGE`.
```kotlin
fun snapPanelTo(panelPosition: PanelPosition)
```
The command that put the Panel Layout in absolute position with coordinates `x` and `y`.
```kotlin
fun popPanelTo(x: Int, y: Int)
```
Define a listener to define actions on different kinds of events.
```kotlin
var panelLayoutCallbacks: PanelLayout.Callbacks?
interface Callbacks {
fun beforeSnap(position: PanelPosition)
fun afterSnap(position: PanelPosition)
fun beforePop(popToX: Int, popToY: Int)
fun afterPop(popToX: Int, popToY: Int)
fun afterClose()
}
```
### Panel Layout attributes
`panel_content` - Resource id of view where is placed the Panel Layout
`panel_view` - Resource id of view inside the Panel Layout
`panel_move_handle` - Resource id of view used for moving the Panel Layout inside of content view
`panel_resize_enabled` - Flag that defines if the Panel Layout is resizable
`panel_snap_to_edges` - Define edges where the Panel Layout could be snapped. Possible values: `all`, `none`, `left`, `top`, `right` and `bottom`
`panel_start_height` - Start height
`panel_start_width` - Start width
### How to Use Panel Layout
Add Panel Layout in your layout:
```xml
<com.wayfair.panellayout.PanelLayout
android:id="@+id/panelLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:panel_content="@id/content"
app:panel_move_handle="@id/moveHandle"
app:panel_resize_enabled="true"
app:panel_resize_handle="@id/resizeHandle"
app:panel_snap_to_edges="all"
app:panel_start_height="300dp"
app:panel_start_width="300dp"
app:panel_view="@id/panel">
<FrameLayout
android:id="@+id/content"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#f3e5f5">
</FrameLayout>
<com.google.android.material.card.MaterialCardView
android:id="@+id/panel"
android:layout_width="300dp"
android:layout_height="300dp"
app:cardBackgroundColor="@color/white">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:id="@+id/moveHandle"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="#e1bee7" />
<ImageView
android:id="@+id/resizeHandle"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_gravity="bottom|end"
android:padding="4dp"
android:src="@drawable/ic_resize"
app:tint="@color/divider" />
</FrameLayout>
</com.google.android.material.card.MaterialCardView>
</com.wayfair.panellayout.PanelLayout>
```
Controls and listeners in the code:
```kotlin
panelLayout.panelVisible = !panelLayout.panelVisible
```
```kotlin
panelLayout.popPanelTo(100, 100)
```
```kotlin
panelLayout.snapPanelTo(PanelPosition.RIGHT_EDGE)
```
```kotlin
panelLayout.panelLayoutCallbacks = object : PanelLayout.Callbacks {
override fun beforeSnap(position: PanelPosition) {
TODO("Not yet implemented")
}
override fun afterSnap(position: PanelPosition) {
TODO("Not yet implemented")
}
override fun beforePop(popToX: Int, popToY: Int) {
TODO("Not yet implemented")
}
override fun afterPop(popToX: Int, popToY: Int) {
TODO("Not yet implemented")
}
override fun afterClose() {
TODO("Not yet implemented")
}
}
```
