Button width in react-native-paper - react-native

I am starting learning react-native-paper, i am not sure how to fix button width, currently it fills whole parent container.
<View>
<Button
icon="camera"
mode="contained"
onPress={() => console.log('Pressed')}
contentStyle={styles.btn}
>
Press me
</Button>
</View>
const styles = StyleSheet.create({
btn: {
width: 30
}
})
This is not working and button is still full width.
Need some help.

You can change the width of Button directly using style props and adding width to it.
<Button
icon="camera"
mode="contained"
onPress={() => console.log('Pressed')}
style={{ width: 100 }}
>
Press me
</Button>

If your View tag is a container for the button, the button needs its own View tag with the styles prop called there.
<View>
<View style={styles.btn}>
<Button
icon="camera"
mode="contained"
onPress={() => console.log('Pressed')}
>
Press me
</Button>
</View>
</View>
const styles = StyleSheet.create({
btn: {
width: 30
},
});

Need to double press to release focus on Text Input from within a Modal with KeyboardAvoidingView

I have a Modal wrapping a KeyboardAvoidingView wrapping a few animated components. One of them is a TextInput and the other is a Button. When clicking on the button, keyboard is first hidden, and then need to click once again to reach the buttons "onPress"
Looked into the solution of wrapping the components with a scroll view and using a the prop keyboardShouldPersistTaps={'always'} but that doesn't work.
constructor(props) {
super(props);
this.paddingInput = new Animated.Value(0);
this.state = {
modalVisible: false,
otherTip: '',
}
}
renderHoveringNote = () => {
const {total, currentTipPercent} = this.props.rootStore.orderStore;
return (
<View>
<KeyboardAvoidingView style={{flex: 1}}>
<Animated.View style={{
marginBottom: this.paddingInput,
flex: 1
}}>
<View>
<Text>Enter custom amount</Text>
</View>
<TextInput
onChangeText={value => {
this.setState({otherTip: value})
}}
autoFocus
value={this.state.otherTip}
/>
<Button title='Save'
onPress={()=>{
...do some stuff here
this.setState({modalVisible: false});
Keyboard.dismiss();
}}
</Animated.View>
</KeyboardAvoidingView>
</View>
)
};
renderOtherTipModal = () => {
return (
<Modal
isVisible={this.state.modalVisible}
onBackdropPress{()=>this.setState({modalVisible:false})}
style={{margin: 0, flex: 1}}
hideModalContentWhileAnimating={true}
>
{this.renderHoveringNote()}
</Modal>
)
};
One click should reach the onPress of the button
Figured it out - I had a few Scroll Views as parents to the Modal. It is important to have ALL of the parent Scroll Views to have keyboardShouldPersistTaps={'always'}.
After adding that, it worked great.

How to set the textinput box above the Keyboard while entering the input field in react native

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

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"

React native textinput multiline is not being pushed up by keyboard

I have a TextInput with multiLine true. However, after two lines the text disappear behind the keyboard. I have tried wrapping the TextInput in KeyboardAvoidingView, but it doesn't work.
The keyboard does push up the TextInput when I unfocus the TextInput and then click on the bottom line. Any idea how I can make the last line of the TextInput stay on top of the keyboard?
The code:
<View style={styles.descriptionFlexStyle}>
<Text
style={[
styles.headerTextStyle,
{ marginTop: Window.height * 0.04 }
]}> Please fill in a reason </Text>
<ScrollView>
<TextInput
style={styles.reasonTextInput}
placeholder="Reason"
value={reasonText}
multiline={true}
onChangeText={input =>
this.setState({
reasonText: input
})
}
underlineColorAndroid="transparent"
ref="reasonTextInput"
/>
</ScrollView>
</View>
hello my dear you must use KeyboardAvoidingView Component from React-Native and put a behavior on it like below :
<KeyboardAvoidingView behavior={'postion' || 'height' || 'padding'}>
<View style={styles.descriptionFlexStyle}>
<Text
style={[
styles.headerTextStyle,
{ marginTop: Window.height * 0.04 }
]}> Please fill in a reason </Text>
<ScrollView>
<TextInput
style={styles.reasonTextInput}
placeholder="Reason"
value={reasonText}
multiline={true}
onChangeText={input =>
this.setState({
reasonText: input
})
}
underlineColorAndroid="transparent"
ref="reasonTextInput"
/>
</ScrollView>
</View>
</KeyboardAvoidingView>
This answer may be a little too late. However, I have found a workaround without using the KeyboardAvoidingView component. A ScrollView could be used instead to scroll the multiline TextInput to the top to have the 'keyboard avoiding' effect. I would use the ref measure() method to get the top y value of the TextInput, before using the scrollTo() method to scroll the TextInput directly to the top of the screen, effectively avoiding the keyboard.
import React, { useRef } from "react";
import { ScrollView, TextInput, View } from "react-native";
export default function Test() {
const scrollViewRef = useRef(null);
const viewRef = useRef(null);
const handleFocus = () => {
viewRef.current.measure((x, y) => {
scrollViewRef.current.scrollTo({ x: 0, y });
});
};
return (
<ScrollView ref={scrollViewRef}>
{/* View to fill up space */}
<View
style={{
width: "80%",
height: 600,
}}
/>
<View ref={viewRef}>
<TextInput
onFocus={handleFocus}
multiline={true}
style={{
width: "80%",
height: 100,
backgroundColor: "whitesmoke",
alignSelf: "center",
}}
/>
{/* View to fill up space */}
<View
style={{
width: "80%",
height: 600,
}}
/>
</View>
</ScrollView>
);
}
Ok i have finally solved it using "KeyboardAvoidingView". I did two things. First i removed the height on my TextInput and then i set the behavior attribute on the "KeyboardAvoidingView" to "padding". Works perfect for me now. Let me know if this help! :)

React-native-popup-menu on react-navigation header

I'm using redux with react-navigation and would like to show the popup when the user clicks on the button on the react-navigation header-right button.
I wrapped the context menu at the root of my apps, as below
return (
<Provider store={store}>
<MenuContext style={{ flex: 1 }}>
<AppWithNavigationState />
</MenuContext>
</Provider>
)
in one of my screen, I have
static navigationOptions = {
headerTitle: 'News',
headerRight: (
<TouchableOpacity style={{ paddingLeft:15, paddingRight:15 }}>
<Icon name="more-vert" size={30} color="black" />
</TouchableOpacity>
),
}
When the user clicks on the right button, it should be like this
The menu items are dynamic, I will have to pull the data from one of my API and start rendering the menu data.
I've read through online it can be achieved using the context method, but I'm not sure how to implement it in my structure.
Could anyone advise me on this?
And is it possible to render it with my local variable?
The most custom way is to use Modal, when click the right button, called this.refs.modalRef.showModal(), which in your current page:
<View>
<PopupModal ref="modalRef" />
</View>
The PopupModal like this:
export default class PopupModal extends Component {
state = {
show: false,
}
showModal() {
this.setState({show: true});
}
closeModal = () => {
this.setState({show: false});
}
return (
<Modal
transparent
visible={this.state.show}
onRequestClose={this.closeModal}
>
<TouchableWithoutFeedback onPress={this.closeModal}>
<View style={{
width: '100%',
height: '100%',
opacity: 0.5,
backgroundColor: 'gray',
}} />
</TouchableWithoutFeedback>
<View></View> // your designed view, mostly position: 'absolute'
</Modal>
);
}
You can also pass some data to PopupModal by this.refs.modalRef.showModal(data), and in PopupModal:
showModal = (data) => {
this.setState({ data, show: true });
}
https://www.npmjs.com/package/react-native-material-menu
It works to me
headerRight:<View style={{marginRight:10}}>
<Menu
ref={this.setMenuRef}
button={<Text onPress={this.showMenu}><Icon style={{color:screenProps.headerTitleStyle.color,fontSize:25,marginRight:5}} name="md-more"/></Text>}
>
<MenuItem onPress={this.hideMenu}>Rate Us</MenuItem>
<MenuItem onPress={this.hideMenu}>Share App</MenuItem>
<MenuItem onPress={this.hideMenu}>Settings</MenuItem>
</Menu>
</View>,

React Native: Scrollview click outside of Textbox

I encountered the following issue: I have a view with two textboxes and one text button. Ones i enter something in the textbox and click on the text button, i have to click twice so that it actually works. If i replace the Scrollview by a View it works. Is there a fix for it?
var TestScreen = React.createClass({
render: function() {
var self = this;
return (
<ScrollView>
<TextInput
placeholder='test'
style = {{
height: 50,
backgroundColor: 'green',
}} />
<TextInput
placeholder='test'
style = {{
height: 50,
backgroundColor: 'blue',
}} />
<Text onPress={() => alert('click')} style = {{
backgroundColor: 'orange',
}} > Text </Text>
</ScrollView>
);
}
})
Did you try to add keyboardShouldPersistTaps='handled' to the ScrollView props?
<ScrollView keyboardShouldPersistTaps='handled'>
...
</ScrollView>
