I currently use native-base for my application
I have a ListItem that lists the dummy entries and would like to keep the item pressed that the id is saved as true in an array. Someone who can give me a light on how to proceed?
state = {
selected: [] ,
};
onPressAction = (key = int) => {
if (this.state.selected.indexOf(key) < 0) {
tmpSelected = this.state.selected
tmpSelected.push(key)
tmpSelected[key] = true;
this.setState({
selected: tmpSelected,
})
console.log('add '+key);
}
else {
var tmpSelected = this.state.selected.slice()
tmpSelected.splice(key, 1);
this.setState({
selected: tmpSelected
})
console.log('remove '+key);
}
console.log(tmpSelected);
};
<ListItem
key={data.id}
onPress={() => this.onPressAction(data.id)}
selected={this.state.selected[data.id] ? false : true}
