# react-native-bottom-sheet-behavior
react-native wrapper for android [BottomSheetBehavior](https://developer.android.com/reference/android/support/design/widget/BottomSheetBehavior.html), supports [FloatingActionButton](https://developer.android.com/reference/android/support/design/widget/FloatingActionButton.html).
[](https://badge.fury.io/js/react-native-bottom-sheet-behavior)
## Demo
[See the Google Maps gif implementation](https://github.com/cesardeazevedo/react-native-bottom-sheet-behavior/blob/master/example/views/GoogleMapsView.js)
## v1.0.0
This major release v1.0.0 supports anchor state, which means that you can have a middle state between collapsed and expanded.
This version now uses a custom BottomSheetBehavior implementation from
[miguelhincapie/CustomBottomSheetBehavior](https://github.com/miguelhincapie/CustomBottomSheetBehavior)
which is basically a fork from the original design-support, but with anchor state support and colors management,
even though is custom implementation, old version should work as before, and you can also disable the
anchor state with `anchorEnabled` prop which is disabled by default.
## Components
The following components are included in this package:
* CoordinatorLayout
* BottomSheetBehavior
* FloatingActionButton
* MergedAppBarLayout
* ScrollingAppBarLayout
* BackdropBottomSheet
* BottomSheetHeader
**NOTE** We expose some android core components such as `CoordinatorLayout`, `AppBarLayout`, `FloatingActionButton`,
but they are NOT meant to be general purposed, and it may not work out of the context of this library,
so use at your own risk.
### iOS Alternative
If you are wondering some iOS alternative, i highly recommend [react-native-interactable](https://github.com/wix/react-native-interactable) by [wix](https://github.com/wix),
you can see their google maps approach [here](https://github.com/wix/react-native-interactable/blob/master/playground/src/real-life-examples/MapPanel.js),
which is very easy to get started.
## Install
`$ npm install react-native-bottom-sheet-behavior`
### Install with RNPM
`$ react-native link react-native-bottom-sheet-behavior`
### Install Manually
Edit the current files as follows.
android/settings.gradle
```diff
include ':app'
+ include ':react-native-bottom-sheet-behavior'
+ project(':react-native-bottom-sheet-behavior').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-bottom-sheet-behavior/android')
```
android/app/build.gradle
```diff
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation "com.android.support:appcompat-v7:${rootProject.ext.supportLibVersion}"
+ implementation "com.android.support:design:${rootProject.ext.supportLibVersion}"
implementation "com.facebook.react:react-native:+" // From node_modules
+ implementation project(':react-native-bottom-sheet-behavior')
}
```
MainApplication.java
```diff
+ import com.bottomsheetbehavior.BottomSheetBehaviorPackage;
public class MainApplication extends Application implements ReactApplication {
@Override
protected List getPackages() {
return Arrays.asList(
new MainReactPackage(),
+ new BottomSheetBehaviorPackage()
);
}
}
```
## Usage
You will need to wrap your view into a `CoordinatorLayout` to make it work.
```jsx
render() {
return (
BottomSheetBehavior!
)
}
```
> *NOTE*
> Make sure that your view has a `backgroundColor` style to prevent some "bugs" when rendering the container.
### Components Order
You should follow this component order.
```jsx
render() {
return (
Main Content
)
}
```
### Events
In order to get the current bottom sheet state or offset, you can listen to `onStateChange` or `onSlide` respectively.
```jsx
console.log(e.nativeEvent.offset)}
onStateChange={(e) => console.log(e.nativeEvent.state)}
/>
```
## AppBarLayouts
We provide some custom AppBars that has custom behaviors, they automatically connects with BottomSheetBehavior
in order to connects with `ToolbarAndroid` and toggle visibility, both AppBars can also manager StatusBar backgrounds.
Currently, AppBars only supports `ToolbarAndroid` as a child, you may have some troubles trying to render a custom View.
#### ScrollingAppBarLayout
This behavior hides and sets the StatusBar background to transparent when you starting dragging the BottomSheet,
and reappears when the BottomSheet backs to the collapsed state, setting back the StatusBar background color
with `statusBarColor` prop.
#### MergedAppBarLayout
The MergedAppBarLayout behavior appears when the BottomSheet reaches the anchor state (or expanded state if you're not using anchorEnabled).
When the BottomSheet is getting over the MergedAppBar, it will partially sets the height of ToolbarAndroid revealing the
`mergedColor` prop, and when the BottomSheet is fully expanded, it sets the ToolbarAndroid with the `toolbarColor` prop.
```jsx
```
### Translucent App Bars
Both AppBars supports translucent status bar, you can enable with `translucent` prop, which will basically adds top margins and **NOT** change the translucent itself, you should handle the translucent directely on the react-native StatusBar component.
## FloatingActionButton
If you are using FloatingActionButton, the `autoAnchor` prop will automatically connect to BottomSheetBehavior,
in order to follow when it's dragging.
```jsx
```
You still can do it manually though, by doing this.
```js
componentDidMount() {
this.refs.fab.setAnchorId(this.refs.bottomSheet)
}
```
FloatingActionButton's has a custom behavior that hides when closely reaches MergedAppBarLayout.
### Support for react-native-vector-icons
You can also use [react-native-vector-icons](https://github.com/oblador/react-native-vector-icons)
on FloatingActionButton, which will automatically load the icon for you.
```jsx
import Icon from 'react-native-vector-icons/Ionicons'
...
render() {
return (
)
}
```
You can check [GoogleMapsView.js](https://github.com/cesardeazevedo/react-native-bottom-sheet-behavior/blob/master/example/views/GoogleMapsView.js) example.
## BackdropBottomSheet
This component is rendered behind the BottomSheetBehavior, and behave like a parallax when BottomSheet is dragging.
you should pass a fixed `height` prop that may match with `anchorPoint` prop from BottomSheet, in order to achieve a full screen view
when reaches the anchor state.
## BottomSheetHeader
This component abstracts color management between BottomSheet states on the native side,
it will find all and components recursively and handles everything out the box.
## NestedScrollView
If you are not using the anchor point, and want to add some nested scroll, you will need to install the [react-native-nested-scroll-view](https://github.com/cesardeazevedo/react-native-nested-scroll-view)
to allows you to scroll inside bottom sheet continuously.
**Note** the `react-native-nested-scroll-view` is only useful when you are **NOT** using the anchorPoint.
