I am using plugin for Autocomplete Input. I have placed this component in Scrollview. It's other behaviour is fine like displaying suggestion list in popup with our custom design.
Referred Plugin:- Plugin
But onStartShouldSetResponder{()=>true} not working.
Because of that I am unable to scroll my suggestion list.
Here is my implemented code =>
<ScrollView keyboardShouldPersistTaps='always' style={[commonstyles.mainContainer,styles.mainContainer,{marginBottom:20}]}>
<View style={{width:width-30,height:45}}>
<Autocomplete
autoCapitalize="none"
autoCorrect={false}
hideResults={false}
containerStyle={{flex: 1,left: 10,position: 'absolute',right: 10,top: 0,zIndex: 1}}
data={films.length === 1 && comp(query, films[0].name) ? [] : films}
defaultValue={query}
onChangeText={text => this.setState({ query: text })}
placeholder="Select Contact"
renderItem={({ id,name }) => (
<TouchableOpacity onStartShouldSetResponder={()=>{return true;}} activeOpacity={1} onPress={() => this.setState({ query: name })}>
<Text style={{fontSize:Global.DESCRIPTION_FONT_SIZE,color:Global.APP_BLACK_COLOR,borderBottomWidth:0.5,borderColor:Global.APP_BLACK_COLOR,padding:5}}>
{id} {name}
</Text>
</TouchableOpacity>
)}
/>
</View>
</Scrollview>
Please let me know if I am doing something wrong.
Also I am unable to understand implementation of onStartShouldSetResponder() function.
Suggest Autocomplete input example in react native which work like Android AutoCompleteTexview component.
Add scrollEnabled parameter to your Scrollview.
Try with below code
<ScrollView scrollEnabled={this.state.enableScrollViewScroll} keyboardShouldPersistTaps='always' style={[commonstyles.mainContainer,styles.mainContainer,{marginBottom:20}]}>
<View style={{width:width-30,height:45}}>
<Autocomplete
autoCapitalize="none"
autoCorrect={false}
hideResults={false}
onStartShouldSetResponderCapture={() => {
var self=this;
this.setState({ enableScrollViewScroll: false });
console.log("Here==>",self.state.enableScrollViewScroll);
}}
containerStyle={{flex: 1,left: 10,position: 'absolute',right: 10,top: 0,zIndex: 1}}
data={films.length === 1 && comp(query, films[0].name) ? [] : films}
defaultValue={query}
onChangeText={text => this.setState({ query: text })}
placeholder="Select Contact"
renderItem={({ id,name }) => (
<TouchableOpacity activeOpacity={1} onPress={() => this.setState({ query: name,enableScrollViewScroll:true })}>
<Text style= {{fontSize:Global.DESCRIPTION_FONT_SIZE,color:Global.APP_BLACK_COLOR,borderBottomWidth:0.5,borderColor:Global.APP_BLACK_COLOR,padding:5}}>
{id} {name}
</Text>
</TouchableOpacity>
)}
/>
</View>
</Scrollview>

I have a TextInput component, and i want to make text visible when keyboard is on, by default, android will have this, but i don't know why the multiline TextInput just scroll down to the bottom of the text exact the same behavior of single line ( also the cursor at the lastest text)
Here is the code of it
<SafeAreaView style={{ margin: spacingWidth[3], flex: 1 }}>
<View row centerV style={HEADER}>. //just set margin
<TouchableOpacity onPress={() => nav.goBack()}>
<BackArrow name="arrowleft" size={onePercentWidth * 6} />
</TouchableOpacity>
<TouchableOpacity
onPress={() => {
editAndSaveFirebase();
nav.goBack();
dispatch(switchReloadOn());
dispatch(fetchNote(userInfo.email)).then(() =>
dispatch(switchReloadOff())
);
// saveAndNavBack();
}}
>
<Text style={SAVE_NOTE_BT}>Save</Text>
</TouchableOpacity>
</View>
<TextInput
onChangeText={(text) => setNoteHeader(text)}
value={noteHeader}
placeholder="Meaningful header"
style={HEADER_INPUT}
/>
<ScrollView
showsVerticalScrollIndicator={false}
style={{
flex: 1,
}}
contentContainerStyle={{
flexGrow: 1,
}}
> ====> the problem here
<TextInput
scrollEnabled={false}
textAlignVertical={Platform.OS === "android" ? "top" : ""}
onChangeText={(text) => setNoteEdit(text)}
placeholder="Type your secret here..."
value={noteEdit}
multiline
style={NOTE_INPUT}. // i just set the fontSize
/>
</ScrollView>
</SafeAreaView>
);
Here is the behavior i talked about
You should set scrollEnabled: false only for iOS. If you still don't reach the expected behaviour, you can pass ref to the scrollView and scrollToEnd on TextInput focus.
const scrollViewRef = useRef<ScrollView>(null)
const handleInputFocus = () => {
if (isAndroid) {
setTimeout(() => scrollViewRef.current?.scrollToEnd({ animated: true }), 200)
}
}
<ScrollView ref={scrollViewRef}>
<TextInput
{...otherInputProps}
onFocus={handleInputFocus}
scrollEnabled={isAndroid}
/>
</ScrollView>
I need to open touched photo in new screen or modal window, but i can't even get it id with onPress function. Photos parsed from unsplash.com.
I've try to wrap my view with <TouchableWithoutFeedback> and by using onPress{} recieve id of photo that i'm pressed at.
getPhoto function:
_getPhoto = () => {
alert(this.state.item.id);
}
main view:
<TouchableWithoutFeedback onPress={this._getPhoto}>
<View style={styles.MainContainer}>
<FlatList
data={ this.state.dataSource }
numColumns={2}
ItemSeparatorComponent = {this.FlatListItemSeparator}
renderItem={({item}) =>
<View style={{flex:1, flexDirection: 'column'}}>
<Image source = {{ uri: item.urls.raw }} style={styles.imageView} />
</View>
}
keyExtractor={(item, index) => index.toString()}
extraData={this.state}
/>
</View>
</TouchableWithoutFeedback>
I except to recieve at least photo id from json, but most of all i get errors like "undefined is not an object".
I solved this problem doing this:
renderItem={({item}) =>
<TouchableWithoutFeedback onPress = {this._getPhoto.bind(item.id)}>
<View style={{flex:1, flexDirection: 'column'}}>
<Image source = {{ uri: item.urls.raw }} style={styles.imageView} />
</View>
</TouchableWithoutFeedback>
}
but now onPress works on app launch.
The answer was in binding.I'm bind item.id to get function:
renderItem={({item}) =>
<TouchableWithoutFeedback onPress = {this._getPhoto.bind(item.id)}>
<View style={{flex:1, flexDirection: 'column'}}>
<Image source = {{ uri: item.urls.raw }} style={styles.imageView}
</View>
</TouchableWithoutFeedback>
}
And change content of _getPhoto to this:
_getPhoto(){
alert(this);
}
So it's works like it does.
Consider a simple app in React Native that fetches listings from a remote JSON source and displays them on screen.
So far,I've managed to get the results to display using the ListView components in rows (i.e. 2 result per row, see screenshot).
in one row.both the grids display data of a single person,i want
details in a consecutive manner not repeating.
</Content>
<View style={{backgroundColor: 'white'}}>
<Text style={{color: 'black',fontSize: 17,marginTop: 25,marginLeft: 15}}>Employees</Text>
</View>
<List dataArray={currentContext.props.employeeList}
renderRow={(data) =>
<ListItem>
{this.renderRow(data)}
</ListItem>
} />
</Content>
The function renderRow(data) is given by
renderRow(data){
return(
typeOne()
)
function typeOne(){
return(
<View style={styles.gridContainer}>
<Content contentContainerStyle={{
padding:6,
paddingBottom:0
}}>
<View style={{flex:1,}}>
<Row>
{renderCell(data.photo_url, 0,data.name)}
{renderCell(data.photo_url, 1,data.name)}
</Row>
</View>
</Content>
</View>
)
function renderCell(bg,pos,title){
if (pos%2==0) {
return(
<Col style={[{marginRight:3},styles.colStyle]}>
{cellContent(bg,title)}
</Col>
)
}else{
return(
<Col style={[{marginLeft:3},styles.colStyle]}>
{cellContent(bg,title)}
</Col>
)
}
function cellContent(bg,title){
if(bg==null){
return null
}
return(
<Button style={{flex:1,alignSelf:'stretch'}} underLayouColor='red'>
<View style={styles.cellContent}>
<Image style={{height:230,alignItems: 'stretch'}} source={{uri:bg}} blurRadius={1}/>
<View style={[styles.cellTitleBg,{opacity: 0.5,marginTop: 10}]}>
<Text style={[styles.cellTitle,{position:'absolute',bottom:0,right:5}]}>{title}</Text>
</View>
</View>
</Button>
)
}
}
}
}
How can get the list-view to return 2 data's per row ?
I will give you similar question for reference in the below link
ListView grid in React Native
please help me solve this issue.
The style part
const styles = StyleSheet.create({
container: {
flex:1,
backgroundColor:'white',
},
button:{
color:'white'
},
overLayView: {
position:'absolute',
alignSelf:'center',
},
gridContainer: {backgroundColor:'#EDF0F2',flex:1,},
colStyle:{height:210,flex:1,marginBottom:6,marginRight:10,marginLeft:10},
cellContent:{position:'absolute',left:0,right:0,top:0,bottom:0},
cellTitleBg:{bottom:65,backgroundColor:'#778899',height:35},
cellTitle:{bottom:65,color:'white',fontWeight:'bold',fontSize:17,right:0,textAlign:'right',right:0}
})
Maybe use a wrapper library, I recommend this one: https://www.npmjs.com/package/react-native-easy-listview-gridview
Try this out...
pass index from the renderRow function down to this function where this view is defined.
<Button key={index} style={{flex:1,alignSelf:'stretch'}} underLayouColor='red'>
<View key={index} style={styles.cellContent}>
<Image key={index} style={{height:230,alignItems: 'stretch'}} source={{uri:bg}} blurRadius={1}/>
<View key={index} style={[styles.cellTitleBg,{opacity: 0.5,marginTop: 10}]}>
<Text key={index} style={[styles.cellTitle,{position:'absolute',bottom:0,right:5}]}>{title}</Text>
</View>
</View>
</Button>
I need focus the next field input in react native, in android platform.
But the focus() function, not exists in android react native, only in IOS.
How make this ? I use react native with typescript.
The focus function works just fine.
<View style={{flexDirection: 'row'}}>
<Text style={{flex: 1}}>Enter Name: </Text>
<TextInput ref="name" onChangeText={(name) => this.setState({name})} style={{flex: 1}}
onSubmitEditing={() => this.refs.age.focus()}/>
</View>
<View style={{flexDirection: 'row'}}>
<Text style={{flex: 1}}>Enter Age: </Text>
<TextInput ref="age" keyboardType="numeric" onChangeText={(age) => this.setState({age})} style={{flex: 1}}
onSubmitEditing={() => this.refs.sport.focus()}/>
</View>
<View style={{flexDirection: 'row'}}>
<Text style={{flex: 1}}>Enter Favourite Sport: </Text>
<TextInput ref="sport" onChangeText={(sport) => this.setState({sport})} style={{flex: 1}}/>
</View>
Hope this helps. This is for android.
You have to user ref on Inputs where you want to focus on:
<Input
ref={(node) => { this.myInput = node }}
value={this.state.myInput.toString()}
onSubmitEditing={() => { this.myOtherInput.focus() }}/>
<Input
ref={(node) => { this.myOtherInput = node }}
value={this.state.myOtherInput.toString()}/>
You can see that when you submit the editing on the first input you will focus on the second one. you can use this.MY_CUSTOM_REF.focus() wherever you want.
This work for me:
<Input
blurOnSubmit={false}
returnKeyType="next"
onSubmitEditing={() => {
this.passwordInput.wrappedInstance.focus();
}}
/>
<Input
secureTextEntry
ref={(input) => {
this.passwordInput = input;
}}
/>
I insert the function in my customize component.
public focus(){
this.input.focus()
}
Have a look at this article, this might be handy react-native inputs
//Helper function
focusNextField(nextField) {
this.refs[nextField].focus();
}
<TextInput
ref='1'
style={styles.otpInputStyle}
keyboardType='numeric'
secureTextEntry
value={this.props.otp1}
maxLength={1}
onChangeText={(num) => {
this.props.otpCode1(num); //action call
if (num && num.length === 1) {
this.focusNextField('2'); //function call. '2' ref to next input ref
}
}}
/>
import React, { useRef } from 'react';
...
export default function YourFuctionalComponent() {
const input1 = useRef(null);
const imput2 = useRef(null);
const doSomething = () => {}
return(
<>
<TextInput
autoFocus
ref={input1}
onSubmitEditing={() => { imput2.current.focus(); }}
returnKeyType="next"
/>
<TextInput
ref={input2}
onSubmitEditing={() => doSomething()}
returnKeyType="done"
/>
</>
);
}

I'm referring to this in my index.android.js file..
<View>
<CustomView>
...
</CustomView>
</View>
This can be done by React.findNodeHandle.
In your case,
...
var { findNodeHandle } = React;
...
render: function() {
return (
<View>
<CustomView ref="customView">
...
</CustomView>
</View>
);
},
somethingLikeComponentDidMount: function() {
var customViewNativeID = findNodeHandle(this.refs.customView);
// Something else...
}
...
might do the work.
For a working example (natively binding two components), check out here as the JS part and here as the native Java part.
do use refs for the component which can act as the reference for the component
ex:
<View>
<TextInput style={styles.textInput}
ref={'usrname'}
placeholder={'Username'}
placeholderTextColor={'red'}
onChangeText={(userName) => this.setState({userName})}
value={this.state.userName} />
<TouchableOpacity onPress={this._onPressButton}>
<View style={styles.buttonContainer}>
<Text> Submit </Text>
</View>
</TouchableOpacity>
</View>
and onPress:
_onPressButton: function(e){
var x = this.state.userName;
alert(x); //we can also use alert(this.state.userName)
},
