is it possible to change the color of the bottom bar?
I would like to color it white. Do you have any ideas?
Goal:
return (
<Fragment>
<SafeAreaView style={{ flex: 0, backgroundColor: "red" }} />
<SafeAreaView style={{ flex: 1, backgroundColor: "white" }}>
<View style={styles.app}>
<View style={styles.header}>
<Image
accessibilityLabel="React logo"
source={{ uri: logoUri }}
resizeMode="contain"
style={styles.logo}
/>
</View>
<Text style={styles.text}>
This is an example of an app built with{" "}
</Text>
<Text style={styles.text}>To get started, edit .</Text>
<Button onPress={() => {}} title="Example button" />
</View>
</SafeAreaView>
</Fragment>
Can You try this?
Receiving syntax error, SyntaxError: Unexpected token, expected ",". It is for the third to last line ");"
I am having trouble seeing where I need to insert the ",". I have tried in front of the ); and after. No luck. This is while I was adding the code for google sign in for ios. Would appreciate any assistance.

You need to add the other half (false case) to the ternary. In this case if you do not want to render anything you need to return null.

I would like to show on the homepage of my react native app , a view that in turn shows a text element and an icon, then below these 2 I would like to show the amazon logo. I tried but it only shows me the logo.
export default class Header extends Component {
render() {
return (
<View style={{ flex: 1, flexDirection: 'row' }}>
<Text style={styles.Title}>Acquista!</Text>
<Ionicons name="ios-contact" size={42} color='red' style={{ marginTop:
65, marginLeft: 210 }} />
</View> ,
<Logo></Logo>
);
}
}
class Logo extends Component {
render() {
return (
<View>
<Image
style={{ height: 200, width: 200, marginTop: 150 }}
source={require('./assets/images/amazon.jpg')}
/>
</View>
);
}
}
Wrap everything into a View
return (
<View style={{ flex: 1 }}>
<View style={{ flex: 1, flexDirection: 'row' }}>
<Text style={styles.Title}>Acquista!</Text>
<Ionicons name="ios-contact" size={42} color='red' style={{ marginTop: 65, marginLeft: 210 }} />
</View>
<Logo />
</View>
)
I am trying to use the KeyboardAvoidingView with behavior="padding".
When I am trying to enter any text in TextInput, the TextInput field is not moving up. I have added a small view in the end which is moving up but the the view above it.
I have also with KeyboardAvoidingView height property with offset. It was working few components like 2 TextInputs. But when I add all the components the UI goes insane and behave jumbled up.
Any any idea whats happening over here?
Here the link of tutorial which I have followed.
render() {
return (
<View style={styles.backgroundContainer}>
<Loader
loading={this.state.isLoading} />
<KeyboardAvoidingView
keyboardVerticalOffset={10}
style={styles.mainContainer}
behavior='padding' >
<View style={styles.formContainer}>
<View style={[styles.centerContainer, { marginTop: 40 }]}>
<Image source={require('./../../Resources/logo.png')} />
<Text style={{ fontWeight: 'bold', color: 'gray', fontSize: 25 }}>AppName</Text>
<Text style={styles.loginMsg}> Login to your Account </Text>
</View>

I used KeyboardAvoidingView, it also doesn't work.
I found this solution, You can take the base code.
Installation
npm i react-native-keyboard-aware-scroll-view --save
Usage
import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'
<KeyboardAwareScrollView>
<View>
<TextInput />
</View>
</KeyboardAwareScrollView>
You can find it here
The way it worked for me was to use position as behavior and -70 as vertical offset. Any non negative integer was creating a huge unused space when the keyboard pops up.
<KeyboardAvoidingView
style={styles.container}
behavior={Platform.OS === 'ios' ? 'position' : 'height'}
keyboardVerticalOffset={Platform.OS === 'ios' ? -70 : 70}
enabled>
<ScrollView>
...
</ScrollView>
</KeyboardAvoidingView>
<KeyboardAvoidingView
style={styles.mainContainer}
behavior="padding"
enabled
>
<View>.......................</View>
</KeyboardAvoidingView>
'Enabled or disabled KeyboardAvoidingView' should be add.
Keep in mind is always your top Parent with flex:1 then the child is then you text input container
<KeyboardAvoidingView style={{ flex: 1 }}
behavior={Platform.OS === "ios" ? "position" : null} enabled>
<ScrollView>
<View>
<View >
<Text maxFontSizeMultiplier={1.5} >
Sign in to your account{" "}
</Text>
<View
behavior="padding"
enabled
>
<TextInput
placeholder="Email address"
placeholderTextColor={Colors.grey}
style={styles.textInput}
onChangeText={(e) => setEmail(e.trim())}
autoCapitalize="none"
returnKeyType={"done"}
/>
</View>
</View>
</ScrollView>
</KeyboardAvoidingView>
// 2nd Solutions use this package
npm i react-native-keyboard-aware-scroll-view --save
import { KeyboardAwareScrollView } from 'react-native-keyboard-aware-scroll-view'
<KeyboardAwareScrollView>
<View>
<TextInput />
</View>
</KeyboardAwareScrollView>
I have three pickers on screen and I am trying to align text using position absolute and setting top and left values. Screenshot here
Position absolute won't work for different screen sizes as it hard coded. Any suggestions please?
