I currently use Native-base for my application
I have a Listitem that lists dummy entries and I would like to keep the item pressed so that the id is saved as true in an array. Someone who can shed some 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}

Have you tried passing the data.id as a parameter for the onPressAction function? Then you put in a console.log and check that the id is being passed correctly.

I managed to a certain point to pass, after a lot of struggle I understood that I had to replace
onPress={this.onPressAction(data.id)}foronPress={() => this.onPressAction(data.id)}but now I am in trouble because it is not correctly stored the array. Where can I be wrong ? (I added the function in the topic)– Ronnie G. Chagas
