rn-sliding-view is a small customizable library that allows you to add animated sliding views to your screens.
It supports 4 modes: from top to bottom ("top"), from bottom to top ("bottom"), from left to right ("left") and from right to left ("right").
You can customize the component in the way you want, including styling, setting
animation duration, delays, positioning, allow/disable default drag, make your own drag, etc.
yarn add rn-sliding-view
or
npm install rn-sliding-view --save
All you need to do is provide two props: componentVisible and changeVisibilityCallback:
import React, { Component } from 'react';
import { View, Button, Text, TouchableOpacity } from 'react-native';
import SlidingView from 'rn-sliding-view';
export default class App extends Component {
state = {
componentVisible: false,
};
toggleComponentVisibility = () => this.setState({ componentVisible: !this.state.componentVisible });
render() {
return (
<>
<Button
onPress={this.toggleComponentVisibility}
title="tap to toggle rn-sliding-view"
/>
{/* Your other components... */}
<SlidingView
componentVisible={this.state.componentVisible}
changeVisibilityCallback={this.toggleComponentVisibility}
>
{/* any nested components */}
</SlidingView>
</>
);
}
}Default positioning (bottom), default allowed drag, default height and default animation duration. You can explicitly pass position prop, but "bottom" position is default.

});Generally it's up to you what you want to do with the component. By default drag'n'drop is allowed and it has its own behaviour (described below). If you wish you can disable it via disableDrag prop and make your own logic of drag'n'drop or not make it at all. If you're going to make your own logic, make sure you've disabled default behaviour via disableDrag prop.
By default you can drag the component at its any part. Maximum value is component's height (or width, if it has left or right position), minimum is an edge of device's screen. If you don't pass disableAutoDragEnd prop it has the following behaviour: when you release your finger the component evaluates the direction of its move. So on release it either hides the component or returns it to maximum value.
To make your own logic of drag'n'drop you have to pass disableDrag prop. Generally all you need to do is create your own responder and pass it to your child component.
...
componentDidMount() {
this.responders = createResponder({
// ...your code with responders
})
}
render() {
return (
<SlidingView
componentVisible={this.state.sliderVisible}
containerStyle={styles.slidingContainer}
customPositionY={this.state.y}
disableDrag
changeVisibilityCallback={() => this.setState({ sliderVisible: !this.state.sliderVisible })}
>
{/* Your components below */}
<View>
<View {...this.responders} /> <-- This view will be draggable
{/* Your other not draggable components */}
</View>
</SlidingView>
)
}
...After you created your responder and passed it to the component, you can handle it in the way you want. The main thing you have to do now - dynamically update currentPositionY (or currentPositionX) prop.
Important: if you want to pass TouchableOpacity (or other touchable) elements, consider making a distinction between drag and single tap. By default, pan responders override single taps of nested views, so TouchableOpacity won't work. As in example below you can set onStartShouldSetResponderCapture to () => false if you use react-native-gesture-responder library. Or use similar method of native PanResponder class.

|---|---|---|---|---|

| disableDrag | false | false | Boolean | Disables default drag behaviour. |
| disableAutoDragEnd | false | false | Boolean | Disables default finishing drag behaviour (fires on release of touch). |
| changeVisibilityCallback | () => {} | false | Function | Changes visibility of the component. Required, if you use default drag behaviour. Pass the same function you use for changing componentVisible prop. |
| currentPositionX | null | false | Number | Represents horizontal position of the component. Required if you use "left" or "right" position prop. |
| currentPositionY | null | false | Number | Represents vertical position of the component. Required if you use "bottom" or "top" position prop. |
| children | - | false | React.Node | Children components you pass to rn-sliding-view component. |
| containerStyle | {} | false | Object | Custom styles of the component's container |
-
It's better to make your component a single module with separate logic of drag'n'drop, switching between visibility states, etc.
-
Consider using redux/mobX state if you want to pass rn-sliding-view at the top of your application. So you can toggle visibility via single function throughout your app.
-
The place matters. Bounds where the component will be placed are defined by its place in your code. If you nest the component inside of another nested component (not at the top level), it will be placed at the same level in your views hierarchy.
