let SortableListView = require('react-native-sortable-listview');
let React = require('react-native');
let {
  View,
  Text,
  TouchableHighlight
} = React;


let data = { 
  hello: {text: 'world'},
  how: {text: 'are you'},
  test: {text: 123},
  this: {text: 'is'},
  a: {text: 'a'},
  real: {text: 'real'},

  gg: {text: 'gg'},
  hh: {text: 'hh'},
  ii: {text: 'ii'},
  jj: {text: 'jj'},
  kk: {text: 'kk'}
}

let order = Object.keys(data); //Array of keys

let RowComponent = React.createClass({
  render: function() {
    return <TouchableHighlight underlayColor={'#eee'} style={{padding: 25, backgroundColor: "#F8F8F8", borderBottomWidth:1, borderColor: '#eee'}} onLongPress={this.props.onLongPress}> onPressOut={this.props.onPressOut}>
        <Text>{this.props.data.text}</Text>
      </TouchableHighlight>
  }
})

let MyComponent = React.createClass({
  render: function() {
    return <SortableListView
          style={{flex: 1}}
          data={data}
          order={order}
          onRowMoved={e => {
            order.splice(e.to, 0, order.splice(e.from, 1)[0]);
            this.forceUpdate();
          }}
          renderRow={row => <RowComponent data={row} />}
        />
  }
});

module.exports = MyComponent;

Example

See example.js.

Props

SortableListView passes through all the standard ListView properties to ListView, except for dataSource. The renderRow method must render a component that forwards onLongPress and onPressOut methods. Calling the onLongPress method will enable the drag and drop on the row and onPressOut will cancel it.

onRowMoved (Function) - should return a function that is passed a single object when a row is dropped. The object contains three properties from, to, and row. from and to are the order indexes being requested to move. row is all the info available about the row being dropped.
data (Object) - Takes an object.
order (Array) (optional) - Expects an array of keys to determine the current order of rows.
