keyboard pushes "CreateComment" component to top but not enough height ,it's still hides the "CreateComment" component which it includes "InputText"
<ScrollView >
....
</ScrollView>
<KeyboardAvoidingView behavior='position'>
<View style={styles.footer}>
<CreateComment GetComments={()=>this.GetComments()}
roomId={this.state.postID} />
</View>
</KeyboardAvoidingView>
</View>
and here is stlye:
container: {
flex: 1,
},
footer :{
position:'absolute',
bottom:0 },
...
You can change the height you want to specify yourself.
You can use offset
Example
<KeyboardAvoidingView
behavior="position"
keyboardVerticalOffset={100}

I am adding a slider to my App with this code
<View>
<SafeAreaView style={HEADER}>
<SliderBox
style={{ height: '100%' }}
currentImageEmitter={index => setCurrentSliderNumber(index)}
images={data.images}>
</SliderBox>
</SafeAreaView>
</View>
this is the result
I am trying to add a button on the bottom, on top of the slider, so I changed the code this way
<SafeAreaView style={HEADER}>
<SliderBox
style={{ height: '100%' }}
currentImageEmitter={index => setCurrentSliderNumber(index)}
images={data.images}>
</SliderBox>
</SafeAreaView>
<View>
<Button
style={styles.signUpButton}
appearance="ghost"
status="control"
>
Sign Up
</Button>
</View>
</View>
But the result is not the one expected
The Safeareaview is on top of your buttons. Try zIndex
https://docs.expo.dev/ui-programming/z-index/
else post your styling. may position: 'absoulte' will work too
Looking at this example from React Navigation website, between Chat and Contacts, the heights are independent of each other. However, When I tried to implement a top bar, the heights are the same. It takes the height of which ever tab has the most content in it.
But in the example, you can see in Contacts that there may be more contacts where you can scroll, and in Chat, the input field is at the bottom, making it look like that's where it stops.
Here's a screen shot from the example:
Chat tab
Contacts tab
Here's some of my code and what I'm experiencing:
<View style={{backgroundColor: 'orange'}}>
{!loading &&
!loadingProfileInfo &&
typeof data.infoByUser !== 'undefined' && (
<FlatList
data={data.infoByUser}
ListHeaderComponent={
<View>
<UserInfo />
<Tab.Navigator>
<Tab.Screen
name="Test"
component={TestComponent} />
<Tab.Screen
name="New Tab"
component={NewTabComponent}
/>
</Tab.Navigator>
</View>
}
numColumns={2}
renderItem={({item}) => (
<View>
// ...
</View>
)}
keyExtractor={item => item._id}
/>
)}
</View>
TestComponent
<View style={{backgroundColor: 'grey'}}>
<View>
<Text>Test Test</Text>
</View>
<View>
<Text>Test Test</Text>
</View>
<View>
<Text>Test Test</Text>
</View>
<View>
<Text>Test Test</Text>
</View>
<View>
<Text>Test Test</Text>
</View>
</View>
NewTabComponent
<View style={{backgroundColor: 'red'}}>
<Text>new tab</Text>
</View>
Notice how the New Tab has a big gap between the red and the orange, that's from the Test tab's height.
You are rendering your entire navigator as the FlatList 'header'. You shouldn't even use Flatlist in this component. Each screen has a different number of items, and should have its own Flatlist.
To fix this:
Remove the FlatList from your main component (with backgroundColor: 'orange'), and just render the Tab Navigator in that render function.
Inside of TestComponent and NewTabComponent, render a ScrollView (or FlatList) if you need it.
All screens (TestComponent and NewTabComponent) should have a height: '100%' or flex: 1 if you want all screens to take all up all the space of the screen, even when its real height is less than the screen height.
To have heights according to the content inside the particular tab, use Scrollview inside each tab screen. Thank me later if this works perfectly. :)
import * as React from "react";
import { ScrollView, Text, View } from "react-native";
import { createMaterialTopTabNavigator } from "#react-navigation/material-top-tabs";
function Screen1() {
return (
<ScrollView>
<View style={{ flex: 1, alignItems: "center" }}>
<Text style={{ padding: 10 }}>Screen1 </Text>
</View>
</ScrollView>
);
}
function Screen2() {
return (
<ScrollView>
<View style={{ flex: 1, alignItems: "center" }}>
<Text style={{ padding: 10 }}>Screen2</Text>
</View>
</ScrollView>
);
}
function Screen3() {
return (
<ScrollView>
<View style={{ flex: 1, alignItems: "center" }}>
<Text style={{ padding: 10 }}>Screen3 </Text>
</View>
</ScrollView>
);
}
const Tab = createMaterialTopTabNavigator();
export default function TopBarNavigator() {
return (
<Tab.Navigator>
<Tab.Screen name="Screen1" component={Screen1} />
<Tab.Screen name="Screen2" component={Screen2} />
<Tab.Screen name="Screen3" component={Screen3} />
</Tab.Navigator>
);
}
I'm having no idea why you're rendering it inside FlatList as it also inherits props from Scroll View.
<View style={{backgroundColor: 'orange'}}>
<Tab.Navigator>
<Tab.Screen
name="Test"
component={TestComponent} />
<Tab.Screen
name="New Tab"
component={NewTabComponent}
/>
</Tab.Navigator>
</View>
and move the FlatList and other business logics inside the TestComponent or the NewTabComponent.
The point is don't render Tabs inside ScrollView or FlatList or SectionList as they both inherit the props of ScrollView.
After a long research I found out that your problem is because react-native-tab-view (which is used by material-tob-tabs), has this code :
_defineProperty(this, "handleLayout", e => {
const {
height,
width
} = e.nativeEvent.layout;
if (this.state.layout.width === width && this.state.layout.height === height) {
return;
}
this.setState({
layout: {
height,
width
}
});
With option lazy={true} , and using the "New Tab" component on first tab and "Test" on second, you get the right height until you change the tab. When you press on "Test" the layout changes so the height is bigger. After changing tab the height does't change anymore because the layout stays the same ("New Tab" fits perfectly in the bigger height) and doesn't trigger handleLayout from react-native-tab-view.
Hope you can find a way to change the layout again when you change tabs.
I am using react-native TextInput component. Here I need to show the InputBox above the keyboard if the user clicks on the textInput field.
I have tried below but i am facing the issues
1. Keyboard avoiding view
a. Here it shows some empty space below the input box
b. Manually I need to scroll up the screen to see the input field which I was given in the text field
c. Input box section is hiding while placing the mouse inside the input box
2. react-native-Keyboard-aware-scroll-view
a.It shows some empty space below the input box
b.ScrollView is reset to the top of the page after I moving to the next input box
Here I set the Keyboard-aware-scroll-view inside the ScrollView component
Kindly clarify
My example code is
<SafeAreaView>
<KeyboardAvoidingView>
<ScrollView>
<Text>Name</Text>
<AutoTags
//required
suggestions={this.state.suggestedName}
handleAddition={this.handleAddition}
handleDelete={this.handleDelete}
multiline={true}
placeholder="TYPE IN"
blurOnSubmit={true}
style= {styles.style}
/>
</ScrollView>
</KeyboardAvoidingView>
</SafeAreaView>
[https://github.com/APSL/react-native-keyboard-aware-scroll-view]
Give your TextInput a position: absolute styling and change its position using the height returned by the keyboardDidShow and keyboardDidHide events.
Here is a modification of the Keyboard example from the React Native documentation for demonstration:
import React, { Component } from 'react';
import { Keyboard, TextInput } from 'react-native';
class Example extends Component {
state = {
keyboardOffset: 0,
};
componentDidMount() {
this.keyboardDidShowListener = Keyboard.addListener(
'keyboardDidShow',
this._keyboardDidShow,
);
this.keyboardDidHideListener = Keyboard.addListener(
'keyboardDidHide',
this._keyboardDidHide,
);
}
componentWillUnmount() {
this.keyboardDidShowListener.remove();
this.keyboardDidHideListener.remove();
}
_keyboardDidShow(event) {
this.setState({
keyboardOffset: event.endCoordinates.height,
})
}
_keyboardDidHide() {
this.setState({
keyboardOffset: 0,
})
}
render() {
return <View style={{flex: 1}}>
<TextInput
style={{
position: 'absolute',
width: '100%',
bottom: this.state.keyboardOffset,
}}
onSubmitEditing={Keyboard.dismiss}
/>
</View>;
}
}
First of all, You don't need any extra code for Android platform. Only keep your inputs inside a ScrollView. Just use KeyboardAvoidingView to encapsulate the ScrollView for iOS platform.
Create function such as below which holds all the inputs
renderInputs = () => {
return (<ScrollView
showsVerticalScrollIndicator={false}
style={{
flex: 1,
}}
contentContainerStyle={{
flexGrow: 1,
}}>
<Text>Enter Email</Text>
<TextInput
style={styles.text}
underlineColorAndroid="transparent"
/>
</ScrollView>)
}
Then render them inside the main view as below
{Platform.OS === 'android' ? (
this.renderInputs()
) : (
<KeyboardAvoidingView behavior="padding">
{this.renderInputs()}
</KeyboardAvoidingView>
)}
I have used this method and I can assure that it works.
If it is not working then there is a chance that you are missing something.
Hooks version:
const [keyboardOffset, setKeyboardOffset] = useState(0);
const onKeyboardShow = event => setKeyboardOffset(event.endCoordinates.height);
const onKeyboardHide = () => setKeyboardOffset(0);
const keyboardDidShowListener = useRef();
const keyboardDidHideListener = useRef();
useEffect(() => {
keyboardDidShowListener.current = Keyboard.addListener('keyboardWillShow', onKeyboardShow);
keyboardDidHideListener.current = Keyboard.addListener('keyboardWillHide', onKeyboardHide);
return () => {
keyboardDidShowListener.current.remove();
keyboardDidHideListener.current.remove();
};
}, []);
You can use a scrollview and put all components inside the scrollview and add automaticallyAdjustKeyboardInsets property to scrollview.it will solve your problem.
automaticallyAdjustKeyboardInsets Controls whether the ScrollView should automatically adjust its contentInset and
scrollViewInsets when the Keyboard changes its size. The default value is false.
<ScrollView automaticallyAdjustKeyboardInsets={true}>
{allChildComponentsHere}
<View style={{ height: 30 }} />//added some extra space to last element
</ScrollView>
Hope it helps.
you can use KeyboardAvoidingView as follows
if (Platform.OS === 'ios') {
return <KeyboardAvoidingView behavior="padding">
{this.renderChatInputSection()}
</KeyboardAvoidingView>
} else {
return this.renderChatInputSection()
}
Where this.renderChatInputSection() will return the view like textinput for typing message. Hope this will help you.
For android you can set android:windowSoftInputMode="adjustResize" for Activity in AndroidManifest file, thus when the keyboard shows, your screen will resize and if you put the TextInput at the bottom of your screen, it will be keep above keyboard
react-native-keyboard-aware-scroll-view caused similar issue in ios. That's when I came across react-native-keyboard-aware-view. Snippets are pretty much same.
<KeyboardAwareView animated={true}>
<View style={{flex: 1}}>
<ScrollView style={{flex: 1}}>
<Text style={{fontSize: 20, color: '#FFFFFF'}}>A</Text>
<Text style={{fontSize: 20, color: '#FFFFFF'}}>B</Text>
<Text style={{fontSize: 20, color: '#FFFFFF'}}>C</Text>
<Text style={{fontSize: 20, color: '#FFFFFF'}}>D</Text>
</ScrollView>
</View>
<TouchableOpacity style={{height: 50, backgroundColor: 'transparent', alignItems: 'center', justifyContent: 'center', alignSelf: 'stretch'}}>
<Text style={{fontSize: 20, color: '#FFFFFF'}}>Submit</Text>
</TouchableOpacity>
</KeyboardAwareView>
Hope it hepls
You will definitely find this useful from
Keyboard aware scroll view Android issue
I really don't know why you have to add
"androidStatusBar": {
"backgroundColor": "#000000"
}
for KeyboardawareScrollview to work
Note:don't forget to restart the project without the last step it might not work
enjoy!
I faced the same problem when I was working on my side project, and I solved it after tweaking KeyboardAvoidingView somewhat.
I published my solution to npm, please give it a try and give me a feedback! Demo on iOS
Example Snippet
import React from 'react';
import { StyleSheet, TextInput } from 'react-native';
import KeyboardStickyView from 'rn-keyboard-sticky-view';
const KeyboardInput = (props) => {
const [value, setValue] = React.useState('');
return (
<KeyboardStickyView style={styles.keyboardView}>
<TextInput
value={value}
onChangeText={setValue}
onSubmitEditing={() => alert(value)}
placeholder="Write something..."
style={styles.input}
/>
</KeyboardStickyView>
);
}
const styles = StyleSheet.create({
keyboardView: { ... },
input: { ... }
});
export default KeyboardInput;
I based my solution of #basbase solution.
My issue with his solution that it makes the TextInput jumps up without any regard for my overall view.
That wasn't what I wanted in my case, so I did as he suggested but with a small modification
Just give the parent View styling like this:
<View
style={{
flex: 1,
bottom: keyboardOffset,
}}>
And it would work! the only issue is that if the keyboard is open and you scrolled down you would see the extra blank padding at the end of the screen.
android:launchMode="singleTask"
android:windowSoftInputMode="stateAlwaysHidden|adjustPan"
write these two lines in your android/app/src/main/AndroidManifest.xml
in activity tag
flexGrow: 1 is the key.
Use it like below:
<ScrollView contentContainerStyle={styles.container}>
<TextInput
label="Note"
value={currentContact.note}
onChangeText={(text) => setAttribute("note", text)}
/>
</ScrollView>
const styles = StyleSheet.create({
container: {
flexGrow: 1,
},
});
Best and Easy Way is to use Scroll View , It will Automatically take content Up and TextInput will not be hide,Can refer Below Code
<ScrollView style={styles.container}>
<View>
<View style={styles.commonView}>
<Image source={firstNameIcon} style={{width: 25, height: 25}}></Image>
<Text style={styles.commonTxt}>First Name</Text>
</View>
<TextInput
onFocus={() => onFocus('firstName')}
placeholder="First Name"
style={styles.txtInput}
onChangeText={(text) => onChangeText(text, 'firstName')}
value={firstNameValue}
/>
</View>
<View>
<View style={styles.commonView}>
<Image source={LastNameIcon} style={{width: 25, height: 25}}></Image>
<Text style={styles.commonTxt}>Last Name</Text>
</View>
<TextInput
onFocus={() => onFocus('lastName')}
placeholder="Last Name"
style={styles.txtInput}
onChangeText={(text) => onChangeText(text, 'lastName')}
value={lastNameValue}
/>
</View>
<View>
<View style={styles.commonView}>
<Image source={callIcon} style={{width: 25, height: 25}}></Image>
<Text style={styles.commonTxt}>Number</Text>
</View>
<TextInput
onFocus={() => onFocus('number')}
placeholder="Number"
style={styles.txtInput}
onChangeText={(text) => onChangeText(text, 'number')}
value={numberValue}
/>
</View>
<View>
<View style={styles.commonView}>
<Image source={emailIcon} style={{width: 25, height: 25}}></Image>
<Text style={styles.commonTxt}>Email</Text>
</View>
<TextInput
onFocus={() => onFocus('email')}
placeholder="Email"
style={styles.txtInput}
onChangeText={(text) => onChangeText(text, 'email')}
value={emailValue}
/>
</View>
<View style={styles.viewSavebtn}>
<TouchableOpacity style={styles.btn}>
<Text style={styles.saveTxt}>Save</Text>
</TouchableOpacity>
</View>
</ScrollView>
go to your Android>app>src>main> AndroidManifest.xml
write these 2 lines :
android:launchMode="singleTop" android:windowSoftInputMode="adjustPan"
I have a toolbar in my RN app. That toolbar has a button that is oversized on purpose and is overflowing from the component.
The oversized button is covered by an other component in the same page.
touchable:{
backgroundColor:'#3d3d3d',
borderRadius:27.5,
position:'absolute',
left:width/2 -25,
bottom:10,
alignItems:'center',
borderColor:'black',
width:55,
height:55,
justifyContent:'center',
}
Mark up:
render() {
return (
<View style={{flex: 1}}>
<View style={{position:'absolute', width:42,height:42,left:20,top:(height-42)/3,zIndex:3}}>
<Image style={{}} source={require('./Images/Ellipse 36.png')} />
<Image style={{position:'absolute',top:14,left:14}} source={require('./Images/Asset 65.png')} />
</View>
<View style={{position:'absolute', width:42,height:42,right:20,top:(height-42)/3,zIndex:3}}>
<Image style={{}} source={require('./Images/Ellipse 36.png')} />
<Image style={{position:'absolute',top:10,left:12}} source={require('./Images/Asset 66.png')} />
</View>
<View><TopToolbar text='Swipe' navigator={this.props.navigator} user={this.props.user}/></View>
<ScrollView style={{zIndex:1,}}><Inders style={{flex: 1}} navigator={this.props.navigator} credentials={this.props.credentials}/></ScrollView>
<View style={{zIndex:0,}}><BottomToolbar user={this.props.user} navigator={this.props.navigator} credentials={this.props.credentials}/></View>
</View>
)
}
Where Inders is a component.
I tried changing the order of the components but it didn't work.
What is the way to make a button "float" from another component?
Open inspector in the Dev tools menu and find out who cut your component, I also like to set backgroundColor to see their position, it make solve this type of bugs mack more easy.
The solution is to wrap the toolbar in another View, so that the new View is the parent of the element that you want to "float".
I have used ScrollView in other apps adding just a style={styles.container} with the styles. However in this app I am creating in my styles I have alignItems:'flex-start' which throws an error with just style={styles.container} and instead you need to pass in alignItems:'flex-start' through contentContainerStyle={styles.container}.
Error: Invariant Violation: ScrollView child layout (["alignItems"]) must by applied through the contentContainerStyle prop.
However when I add contentContainerStyle when scrolling down in the view, once the finger is lifted off the phone (or release of the mouse in simulator), the scroll automatically goes back to the top. If I just use style={styles.container} and take out the alignItems:'flex-start' it scrolls correctly, but my items in the UI are not laid out how I need them. What is causing it to scroll back to the top with contentContainerStyle and is there a fix?
render:
var _that = this;
var iconsToShow = icons.map(function (icon, i){
if(i < 81){
return (
<TouchableHighlight
onPress={() => _that.changeIcon(indexToChange, icon)}
underlayColor='#F7F7F7'
key={i}>
<Text style={styles.iconText}><IonIcons name={icon} size={30} color="#555" /></Text>
</TouchableHighlight>
);
}
});
return (
<Carousel width={SCREEN_WIDTH} animate={false} indicatorColor="#444" inactiveIndicatorColor="#999" indicatorAtBottom={false} indicatorOffset={16}>
<View>
<ScrollView contentContainerStyle={styles.container}>{iconsToShow}</ScrollView>
</View>
<View>
//next page for carousel
</View>
</Carousel>
);
I figured out how to get it to scroll. Instead of having the View wrapping the ScrollView and the ScrollView having any flex styling or alignItems:'flex-start' with contentContainerStyle={styles.container}, put that on the View which is a child of the ScrollView and just use style= instead of contentContainerStyle=.
render:
<ScrollView style={styles.container}>
<Text style={styles.goalName}>{goal}</Text>
<View style={styles.viewContainer}>
{iconsToShow}
</View>
</ScrollView>
Styling:
var styles = StyleSheet.create({
container: {
backgroundColor: 'transparent',
paddingLeft:20,
paddingRight:20
},
viewContainer:{
flexDirection:'row',
flexWrap: 'wrap',
alignItems: 'flex-start',
flex: 1
},
iconText:{
paddingLeft:15,
paddingRight:15,
paddingTop:15,
paddingBottom:15
},
goalName:{
textAlign:'center',
marginTop:40,
marginBottom:10,
fontSize:20
}
});
If someone still couldn't fix the problem, try put {flex: 1} into "all" parents of the ScrollView
