Return next page and close current page after loads in React Native

I'm newbie in React-native and I'm confused on how can I pass the parameter to another js file when returning a View, The second problem , The code I used below is when returning home the previous page(login) didn't close or gone and the home didn't view properly. I'm aware using react-nativigation but it's hard for me to implement but is there any other way to direct login when it loads? please need some help for this , here's my code,
Login.js After login from googlesignin when the state loaded it goes to another activity
import { Home } from "../screens"
render() {
return (
<View style={styles.container}>
<GoogleSigninButton
style={{ width: 222, height: 48 }}
size={GoogleSigninButton.Size.Wide}
color={GoogleSigninButton.Color.Dark}
onPress={this.signIn}
/>
{this.state.loaded ?
<View style={{ width: 160, marginTop: 10 }}>
{renderLogin(this)} //return some value
</View>
: <Text>Not signIn</Text>}
</View>
);
}
}
function renderLogin(ts) {
return (
<Home /> // i want to pass value to home js example: 'ts.state.userGoogleInfo.user.photo'
)

React Native onPress being called automatically withNavigation

I would think that onPress should only work when it is triggered by a touch event. This used to be the case, but when I used withNavigation in a screen not in the StackNavigator, onPress seems to be rendering automatically.

Is there something wrong with the way I'm calling onPress={this.props.openMenu} in HomeScreen.js? I have tried onPress={()=>this.props.openMenu} to no avail.

Try to comment those two out:
componentDidMount() {
// this.toggleMenu();
}
componentDidUpdate() {
// this.toggleMenu();
}

Passing data to custom picker

Currently I'm developing an app with a picker on it and I'm using picker component from react native but it doesn't work perfectly on iOS device so I found a custom picker using picker and modal it renders a modal on iOS only.
Here is the code
class PickerWrapper extends React.Component {
constructor(props) {
super(props);
this.state = {
type_absen: '',
modal: false,
}
}
render() {
let picker;
let iosPickerModal = (
<Modal isVisible={this.state.modal} hideModalContentWhileAnimating={true} backdropColor={color.white} backdropOpacity={0.9} animationIn="zoomInDown" animationOut="zoomOutUp" animationInTiming={200} animationOutTiming={200} onBackButtonPress={() => this.setState({ modal: false })} onBackdropPress={() => this.setState({ modal: false })} >
<View style={{ backgroundColor: color.white, width: 0.9 * windowWidth(), height: 0.3 * windowHeight(), justifyContent: 'center' }}>
<Picker
selectedValue={this.state.type_absen}
onValueChange={(itemValue, itemIndex) => {
this.setState({ type_absen: itemValue });
this.setState({ modal: false });
setTimeout(() => this.props.onSelect(itemValue), 1200);
}}
>
{this.props.items.map((item, key) => <Picker.Item label={item} value={item} key={key} />)}
</Picker>
</View>
</Modal>);
if (Platform.OS === 'ios')
return (
<View style={this.props.style}>
{iosPickerModal}
<TouchableOpacity onPress={() => this.setState({ modal: true })}>
<View style={{ flexDirection: 'row', height: this.props.height ? this.props.height : normalize(40), width: this.props.width ? this.props.width : 0.68 * windowWidth(), borderWidth: 1, borderColor: color.blue, alignItems: 'center', borderRadius: 5 }}>
<Text style={{ fontSize: fontSize.regular, marginRight: 30 }}> {this.state.type_absen}</Text>
<IconWrapper name='md-arrow-dropdown' type='ionicon' color={color.light_grey} size={20} onPress={() => this.setState({ modal: true })} style={{ position: 'absolute', right: 10 }} />
</View>
</TouchableOpacity>
</View >);
else
return (
<View style={this.props.style} >
<Picker
selectedValue={this.state.type_absen}
style={{ height: this.props.height ? this.props.height : normalize(20), width: this.props.width ? this.props.width : normalize(150) }}
onValueChange={(itemValue, itemIndex) => {
this.setState({ type_absen: itemValue });
this.props.onSelect(itemValue);
}}
>
{this.props.items.map((item, key) => <Picker.Item label={item} value={item} key={key} />)}
</Picker>
</View>);
}
}
PickerWrapper.propTypes = {
onSelect: PropTypes.func.isRequired
}
export default PickerWrapper;
I successfully load the data from api, but I still confused on how to get the value from it, and here is my old code using picker component
<Picker
selectedValue={this.state.type_absen}
style={{backgroundColor:'white'}}
onValueChange={(val) => this.setState({ type_absen: val })}>
{
this.props.schedules ? this.props.schedules.map((item, key) => {
return <Picker.Item value={item.id} label {item.description} key={item.id} />})
:
[]
}
</Picker>
and this is my new code using the PickerWrapper
export const mapStateToProps = state => ({
token: state.authReducer.token,
message: state.authReducer.message,
schedules: state.authReducer.schedules
});
export const mapDispatchToProps = (dispatch) => ({
actionsAuth: bindActionCreators(authAction, dispatch)
});
class Change extends Component {
constructor(){
super();
this.state={
type_absen: [],
}
}
onPickerValueChange=(value, index)=>{
this.setState({type_absen: value},
() => {
Alert.alert("type_absen", this.state.type_absen);
}
);
}
render() {
return (
<View style={styles.container}>
<View style={styles.container}>
<View style={styles.innerContainer}>
<PickerWrapper items={this.props.schedules.map((item) => item.description )} onSelect={this.onPickerValueChange} />
</View>
</View>
</View>
);
}
}
}
what I'm trying to do is get the item.id. How do I do that in my PickerWrapper component?

In the class component change the picker wrapper like this
export const mapStateToProps = state => ({
token: state.authReducer.token,
message: state.authReducer.message,
schedules: state.authReducer.schedules
});
export const mapDispatchToProps = (dispatch) => ({
actionsAuth: bindActionCreators(authAction, dispatch)
});
class Change extends Component {
constructor(){
super();
this.state={
type_absen: [],
}
}
onPickerValueChange=(value, index)=>{
this.setState({type_absen: value},
() => {
Alert.alert("type_absen", this.state.type_absen);
}
);
}
render() {
return (
<View style={styles.container}>
<View style={styles.container}>
<View style={styles.innerContainer}>
<PickerWrapper items={this.props.schedules} onSelect={this.onPickerValueChange.bind(this)} />
</View>
</View>
</View>
);
}
}
and then in your PickerWrapper component change it to be like this
class PickerWrapper extends React.Component {
constructor(props) {
super(props);
this.state = {
type_absen: '',
modal: false,
}
}
render() {
let picker;
let iosPickerModal = (
<Modal isVisible={this.state.modal} hideModalContentWhileAnimating={true} backdropColor={color.white} backdropOpacity={0.9} animationIn="zoomInDown" animationOut="zoomOutUp" animationInTiming={200} animationOutTiming={200} onBackButtonPress={() => this.setState({ modal: false })} onBackdropPress={() => this.setState({ modal: false })} >
<View style={{ backgroundColor: color.white, width: 0.9 * windowWidth(), height: 0.3 * windowHeight(), justifyContent: 'center' }}>
<Picker
selectedValue={this.state.type_absen}
onValueChange={(itemValue, itemIndex) => {
this.setState({ type_absen: itemValue });
this.setState({ modal: false });
setTimeout(() => this.props.onSelect(itemValue), 1200);
}}
>
{this.props.items.map((item, key) => <Picker.Item label={item.description} value={item.id} key={key} />)}
</Picker>
</View>
</Modal>);
if (Platform.OS === 'ios')
return (
<View style={this.props.style}>
{iosPickerModal}
<TouchableOpacity onPress={() => this.setState({ modal: true })}>
<View style={{ flexDirection: 'row', height: this.props.height ? this.props.height : normalize(40), width: this.props.width ? this.props.width : 0.68 * windowWidth(), borderWidth: 1, borderColor: color.blue, alignItems: 'center', borderRadius: 5 }}>
<Text style={{ fontSize: fontSize.regular, marginRight: 30 }}> {this.state.type_absen}</Text>
<IconWrapper name='md-arrow-dropdown' type='ionicon' color={color.light_grey} size={20} onPress={() => this.setState({ modal: true })} style={{ position: 'absolute', right: 10 }} />
</View>
</TouchableOpacity>
</View >);
else
return (
<View style={this.props.style} >
<Picker
selectedValue={this.state.type_absen}
style={{ height: this.props.height ? this.props.height : normalize(20), width: this.props.width ? this.props.width : normalize(150) }}
onValueChange={(itemValue, itemIndex) => {
this.setState({ type_absen: itemValue });
this.props.onSelect(itemValue, index);
}}
>
{this.props.items.map((item, key) => <Picker.Item label={item.description} value={item.id} key={key} />)}

React Native Redux causing whole page to render upon calling function

I have an issue with React Native Redux where I am calling a Redux action from the onChangeText function from inside a TextField. Normally, an update like this would only cause the TextField itself to update, however the whole page is being re-rendered upon each call of the function.
Here is the code for the TextField. The method in question is this.props.updateURL(value)
<TextField label='Server'
value={this.props.profile.url}
labelFontSize={textFont(16)}
tintColor='#B3B2B6'
autoCapitalize="none"
autoCorrect={false}
returnKeyType={'next'}
blurOnSubmit={false}
autoFocus={!this.props.profile.edited}
style={styles.inputStyle}
selectionColor={CUSRSOR_COLOR}
editable={!this.props.profile.edited}
onChangeText={async value => {
this.props.updateURL(value)
}}
renderAccessory={()=>{
return(<TouchableOpacity onPress={this.handleScanPress} >
<Image source={ImgScan} style={{height: 25, width: 25, overflow:'visible', marginBottom:20, marginRight: 10}}/>
</TouchableOpacity>);
}}
>
</TextField>
This is for the Redux methods mapStateToProps and mapDispatchToProps:
const mapStateToProps = (state) => {
return {
profile : state.profileReducer,
deviceUid: state.GlobalReducer.deviceUid,
locationsList: state.LogsReducer.locationList,
errorList: state.ErrorsReducer.failedList,
watermarkText: state.GlobalReducer.watermarkText,
alertPresent: state.LogsReducer.alertPresent
}
};

updateDeviceAction: (action,deviceId,url) => dispatch(performDeviceAction(action,deviceId,url)),
callLogoutApi: (userName,password) => dispatch(callLogoutApi(userName,password)),
syncDeviceActions: () => dispatch(syncDeviceActions()),
syncPendingUpdates: (url,userName,password,deviceId) => dispatch(syncPendingUpdates(url,userName,password,deviceId)),
fetchPendingLocationsList: () => dispatch(fetchPendingLocationsList()),

const profileReducer = (state=initialState,action) => {
switch (action.type) {
case actionTypes.UPDATE_URL :
return {
...state,
url: action.payload
}
...
}
This is the Redux action:
export const updateURL = (url) => {
return {
type: actionTypes.UPDATE_URL,
payload: url
};
};
Any help would be much appreciated.

react-native Swiper is blank inside a modal

i use react-native and react-native-swiper
Which OS ?
Android
Version
Which versions are you using:
react-native-swiper v1.5.13?
react-native v0.51.0
Actual behaviour
I display a Modal with swiper inside it. I get a blank display, only the button of the swiper but not the content
Expected behaviour
To show the content of the swiper inside a modal
How to reproduce it>
I tryed to reproduce the bug with a very simplified version of my code
try it in snack
https://snack.expo.io/rk8rb3ZzM
or my code
import React, { Component } from "react";
import { Text, View, Modal, Dimensions } from "react-native";
import Swiper from "react-native-swiper"; // 1.5.13
import { Button } from "react-native-elements"; // 0.18.5
import "#expo/vector-icons"; // 6.2.1
var width = Dimensions.get("window").width;
var height = Dimensions.get("window").height;
export default class extends Component {
constructor(props) {
super(props);
this.state = {
items:[
{ title: "Hello Swiper", css: thisstyles.slide1 },
{ title: "Beautiful", css: thisstyles.slide2 },
{ title: "simple", css: thisstyles.slide3 },
{ title: "And simple", css: thisstyles.slide3 }
],
modalVisible: false
};
}
componentDidMount() {
}
// affiche / cache la modal avec l'image en plein écran
toggleModalVisible = () => {
this.setState({ modalVisible: !this.state.modalVisible });
};
// vue plein écran avec zoom sans info
renderFullScreen() {
if (!this.state.modalVisible) {
return null;
}
return (
<Modal
animationType={"slide"}
transparent={false}
visible={this.state.modalVisible}
onRequestClose={() => this.toggleModalVisible()}
>
<View style={thisstyles.modalFullScreen}>
<Text>I have component and text here</Text>
<Swiper style={thisstyles.wrapper} showsButtons={true}>
{this.state.items.map((item, key) => {
console.log("item", item);
return (
<View key={key} style={item.css}>
<Text style={thisstyles.text}>{item.title}</Text>
</View>
);
})}
</Swiper>
</View>
</Modal>
);
}
render() {
return (
<Swiper style={thisstyles.wrapper} showsButtons={true}>
{this.state.items.map((item, key) => {
console.log("item", item);
return (
<View key={key} style={item.css}>
<Text style={thisstyles.text}>{item.title}</Text>
{this.renderFullScreen()}
<Button
title="modal"
onPress={() => this.toggleModalVisible()}
icon={{ name: "close", type: "font-awesome" }}
/>
</View>
);
})}
</Swiper>
);
}
}
const thisstyles = {
modalFullScreen: {
height: height,
width: width
},
wrapper: {},
slide1: {
flex: 1,
justifyContent: "center",
alignItems: "center",
backgroundColor: "#9DD6EB"
},
slide2: {
flex: 1,
justifyContent: "center",
alignItems: "center",
backgroundColor: "#97CAE5"
},
slide3: {
flex: 1,
justifyContent: "center",
alignItems: "center",
backgroundColor: "#92BBD9"
},
text: {
color: "black",
fontSize: 30,
fontWeight: "bold"
}
};
Steps to reproduce
run the app
click on the button "x modal"

I had to add a delay to get mine to work, but yes it works!
constructor(props) {
super(props);
this.state = { showSwiper: false };
}
componentDidMount() {
// Must use this 100-ms delayed swiper workaround to render on Android properly
setTimeout(() => {
this.setState({showSwiper: true});
}, 100);
}
render() {
var exampleSwiper = (
<Swiper activeDotColor={'white'} loop={false} >
<View style={{width: 100, height: 100, backgroundColor: 'white'}} />
<View style={{width: 100, height: 100, backgroundColor: 'white'}} />
<View style={{width: 100, height: 100, backgroundColor: 'white'}} />
</Swiper>
);
return (
<Modal presentationStyle={'overFullScreen'}>
{this.state.showSwiper ? exampleSwiper : null}
</Modal>
);
}

Create one parent View tag and set its height based on your requirement. For example:
<View style={{height:'50%'}}>
<Swiper {....} />
</View>
