How to update text using TextInput

I'm having some troubles trying to figure out how to edit a text thats already been made.
I have done most of the things and the one i'm stuck at is the button that updates the text to the new updated text. I can see the updated text when I use console.log but it doesn't update the text. Thats still the same. Below you can see the full code and I think the updateTodo function is done wrong.
export default function App() {
const [updateTaskId, setUpdateTaskId] = useState('');
const [updateTaskTitle, setUpdateTaskTitle] = useState('');
const [todos, setTodos] = useState([]);
const updateTodo = () => {
const todoAsync = [
...todos,
{
key: updateTaskId,
name: updateTaskTitle,
},
];
setTodos(todoAsync);
};
const renderitem = ({item}) => {
return (
<View
style={{
flex: 1,
backgroundColor: colors.card,
margin: 10,
elevation: 1,
borderRadius: 10,
padding: 10,
}}>
<View style={{flexDirection: 'row'}}>
<Fontisto
name={item.isChecked ? 'checkbox-active' : 'checkbox-passive'}
size={20}
color={colors.text}
onPress={() => checkTodo(item.key)}
/>

setUpdateModal(true);
setUpdateTaskTitle(item.name);

Here is what you need to do.
make a copy of all todos
filter out the todo that you are about to update out of the todos array
concat a new todo with the new text to the array of todos
it should render as expected
const updateTodo = () => {
const todoAsync = [
...todos,
].filter((item) => item.id !== updateTaskId).concat([{
key: updateTaskId,
name: updateTaskTitle,
}])
setTodos(todoAsync);
};
Try this if you want to keep the same todo on the screen but only update the object key for name.
const updateTodo = () => {
const todoAsync = [
...todos,
].map((item) => {
const { key } = item;
if(key === updateTaskId} {
// return updated object
return {
key,
name: updateTaskTitle,
}
}
else return item;
}
setTodos(todoAsync);
};

.map() function displays my hidden animated view for each child in React Native. And I am using keys and id

I have a hidden animated view that displays when you click on the specific account name. Currently, when you click an account name, the animated hidden view displays for all the children in the .map() function. I tried adding the key and id to the animated view as well but that does not work either. Still shows the hidden animated view for all the children in the map.
<ScrollView style={{flex: 1}} showsVerticalScrollIndicator={true}>
{accounts.map(account => (
<View key={account.id} id={account.id}>
<View
style={{
width: '100%',
backgroundColor: colors.primary,
borderRadius: 10,
padding: 10,
marginBottom: 10,
marginTop: 10,
zIndex: 1,
}}>
<View
style={{
flex: 1,
flexDirection: 'row',
}}>
<Text
onPress={() => setHidden(!hidden)}
style={{
fontSize: 30,
textAlign: 'left',
flex: 1,
marginTop: 'auto',
marginBottom: 'auto',
}}>
{account.name}
</Text>
<View>
<Text
style={{
fontSize: 30,
textAlign: 'right',
flex: 1,
marginBottom: 10,
}}>
{account.amount}
</Text>
<View
style={{
flexDirection: 'row',
justifyContent: 'flex-end',
}}>
<DeleteAccount account={account.name} />
<Icon name="wrench" size={25} color="#000000" />
</View>
</View>
</View>
</View>
{hidden ? (
<Animated.View
key={account.id}
id={account.id}
style={[
styles.subView,
{transform: [{translateY: bounceValue}]},
]}>
<Text>{account.name}</Text>
</Animated.View>
) : null}
</View>
))}
</ScrollView>```

Keyboard Avoiding View - React-Native?

I have a sign-up screen "Inputs", I want when user select input doesn't hide other, so I wrap it inside <KeyboardAvoidingView> and set behavior "padding" but after choosing some input I see a View cover all my content so I can't see any things "just white View"
So maybe I made something wrong when using it, how can I handle it?

How to place two buttons within the same row in react native?

Within a popup dialog I want to buttons to be placed on the same line but now I'm getting like this https://i.stack.imgur.com/sJ30p.png.Following is the style given.
<PopupDialog
ref={popupDialog => {
this.popupDialog = popupDialog;
}}
dialogStyle={{ backgroundColor: "#ddd", height: 200, width:320, border:10,padding:10}}
overlayBackgroundColor="#fff"
dismissOnTouchOutside={true}
>
<View style={styles.dialogContentView}>
<Text style={{fontSize:18}}>Are you sure you want to submit?</Text>
<View style={styles.button_1}>
<Button
title="Yes"
onPress={() => {
console.log('clicked')
}}
/>
</View>
<View style={styles.button_1}>
<Button
title="No"
onPress={() => {
console.log('clicked')
}}
/>
</View>
</View>
</PopupDialog>
.....
....
dialogContentView: {
flex: 1,
flexDirection: 'column',
justifyContent: 'space-between'
},
button_1:{
width: '40%',
height: 30,
}

Add View parent to both Button component with style flexDirection: 'row' after </Text>
<View style={{ flexDirection: 'row' }}>
<View style={styles.button_1}>
<Button
title="Yes"
onPress={() => {
console.log('clicked');
}}
/>
</View>
<View style={styles.button_1}>
<Button
title="No"
onPress={() => {
console.log('clicked');
}}
/>
</View>
</View>
You can try this snack

Try this for full width without any spaces or margin JUST COPY PASTE
<View style={{ flexDirection: "row" }}>
<View style={{ flex: 1 }}>
<TouchableOpacity style={{ alignSelf: 'stretch',backgroundColor: '#2980B9' }} onPress={() => { onSavePress }}>
<Text style={{ alignSelf: 'center',
color: '#ffffff',
fontSize: 16,
fontWeight: '600',
paddingTop: 10,
paddingBottom: 10 }}>Save</Text>
</TouchableOpacity>
</View>
<View style={{borderLeftWidth: 1,borderLeftColor: 'white'}}/>
<View style={{ flex: 1}}>
<TouchableOpacity style={{ alignSelf: 'stretch',backgroundColor: '#2980B9'}} onPress={() => { onCancelPress }}>
<Text style={{ alignSelf: 'center',
color: '#ffffff',
fontSize: 16,
fontWeight: '600',
paddingTop: 10,
paddingBottom: 10 }}>Cancel</Text>
</TouchableOpacity>
</View>
</View>

To do that, I usually create a view, set its flexDirection to 'row' and put the button components inside of it. So, your code would look like this:
<View style={{ flexDirection: 'row' }}>
<Button title='Button 1'/>
<Button title='Button 2'/>
</View>
I hope it helps.

Set page of viewpager in component

I think you should use componentDidUpdate
Like this
componentDidUpdate(){
if(this.props.home && this.props.services){
this.viewPager.setPage(0);
}
}
