Install

For React Native version >=0.28.x use version >=0.3.x (0.2.x is broken, sorry!):

npm install --save react-native-loading-spinner-overlay@latest

For React Native version <=0.27.x use version 0.1.x:

npm install --save [email protected]

Usage

This usage shows the default styles and properties.

• You can pass a String size prop that can either be "large" or "small" (no other cross-platform sizes are supported right now, and by default it is "large")
• You can pass a String color ColorProp (e.g. red or #ff0000) to change the default spinner color (by default it is "white" for high contrast on the default overlayColor; see below)
• You can control visibility of the spinner using the Boolean prop visible (Boolean, by default it is false)
• To change the color of the overlay, pass a ColorProp as the overlayColor prop (e.g. 'rgba(0,0,0,0.25)')
• Optional text field, activate by passing textContent Prop and style by passing textStyle Prop
• You can also pass a custom view to act as activity indicator.

import React, { View, Text } from 'react-native';

import Spinner from 'react-native-loading-spinner-overlay';

class MyComponent extends React.Component {

  constructor(props) {
    super();
    this.state = {
      visible: false
    };
  }

  /* eslint react/no-did-mount-set-state: 0 */
  componentDidMount() {
    setInterval(() => {
      this.setState({
        visible: !this.state.visible
      });
    }, 3000);
  }

  render() {
    return (
      <View style={{ flex: 1 }}>
        <Spinner visible={this.state.visible} textContent={"Loading..."} textStyle={{color: '#FFF'}} />
      </View>
    );
  }
}

To use a custom activity indicator just pass it as child of the component:

<Spinner visible={this.state.visible}>
  <Text>This is my custom spinner</Text>
</Spinner>

Platforms

For >= 0.3.x:

• We use ActivityIndicator now!

For 0.2.x:

• Do not use this version due to #22, use >= 0.3.x please!

For <= 0.1.x:

• iOS: this platform uses Modal (docs/source) to overlay and ActivityIndicatorIOS (docs) for the loading spinner
• Android: this platform uses Portal (source) to overlay and ActivityIndicator (docs) for the loading spinner

Notes

For >= 0.3.x:

• We use ActivityIndicator now!

For 0.2.x:

• This version is broken due to a dependency issue, see issue #22

For <= 0.1.x:

• Docs don't exist yet for Portal, see this issue on GitHub; once those are in, then we can add a link to the source in Platforms
• Until a release of React Native is shipped for this pull request, Android's ProgressBarAndroid will not have support for a StyleAttr value of "Normal" - therefore we only support a size prop of "small" or "large" right now (defaulting to "large") - in other words, we can only support Android's inverse styling with a styleAttr of "Inverse", "SmallInverse" (for a size prop of "small"), and "LargeInverse" (for a size prop of "large") (since there is no "Normal" support right now for "size" of "normal").
