KeyBoardAvoidingView hides content - android

enter image description here
Current Behaviour
The KeyBoardAvoidingView hides the Login button.
Its the same on Android and on iPhone.
On an Android Tablet It hides the Login button but since the screen is large you can see the button halfway from the top.
Expected Behaviour
I want the Login button at the bottom to move into the app frame when user wants to input his login details.

The problem is that KeyboardAvoidingView cannot correctly apply padding if it's children doesn't have plain size set. In this particular case you need to figure out the screen dimenson and apply screen height (minus navigation bar height) to your root View style:
import { Dimensions } from 'react-native';
const { screenHeight: height } = Dimensions.get('window');
const styles = StyleSheet.create({
...
containerContent: {
height: screenHeight - navBarHeight,
justifyContent: 'center',
}
...
},
And apply it in your render method:
render() {
return (
<KeyboardAvoidingView behavior="padding" style={styles.container}>
<View style={styles.containerContent}>
...
</View>
</KeyboardAvoidingView>
);
}


I am still seeing that on keyboard open the toolbar is being pushed up out of visible area. This is the code :
<KeyboardAvoidingView style={styles.containerContent}>
<View style={styles.containerContent}>
<GiftedChat
messages={}
onSend={this.onSend}
renderAvatar={null}
user={{
_id: 1,
}}
imageStyle={{}}
/>
</View>
</KeyboardAvoidingView>
const styles = StyleSheet.create({
containerContent: {
height: Dimensions.get('window').height - kHeaderHeight,
justifyContent: 'center',
flex: 1,
},
});

Inner nested React Native swiper doesn't show any content

I'm trying to make two nested swipers on Android with React Native, using react-native-swiper. Each swiper works correctly when is separate, but when I add one to the other, the inner nested swiper doesn't show any content. It's a little bit weird, it recognized its children, I can swipe but Views are not rendered. Here is my simple demonstration example:
import React from 'react'
import {
Text,
View
} from 'react-native'
import Swiper from 'react-native-swiper'
const Dimensions = require('Dimensions');
const window = Dimensions.get('window');
var styles = {
wrapper: {
backgroundColor: 'transparent'
},
innerSwiper: {
width: window.width,
height: window.height / 3,
marginTop: 60,
backgroundColor: '#92BBD9'
},
slide1: {
flex: 1,
alignItems: 'center',
backgroundColor: '#9DD6EB'
},
slide2: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#97CAE5'
},
slide3: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#92BBD9'
},
text: {
color: '#fff',
fontSize: 30,
fontWeight: 'bold'
}
}
export default () =>
<Swiper style={styles.wrapper} showsButtons>
<View style={styles.slide1}>
<View style={styles.innerSwiper}>
<Swiper style={styles.wrapper} showsButtons>
<View style={styles.slide1}>
<Text style={styles.text}>Hello Swiper</Text>
</View>
<View style={styles.slide2}>
<Text style={styles.text}>Beautiful</Text>
</View>
<View style={styles.slide3}>
<Text style={styles.text}>And simple</Text>
</View>
</Swiper>
</View>
</View>
<View style={styles.slide2}>
<Text style={styles.text}>Beautiful</Text>
</View>

I have solved this issue. I commented one line
const HomePages = StackNavigator({
HomePage: { screen: Home },
AboutPage: { screen: About },
// MainPage:{ screen: Main}, //Commenting this line solved the issue
});
Maybe main page reference was already created that's why it was creating the problem.

React Native: Undefined is not a function(evaluating this.props...)

I'm trying to a implement a logic to display some data fetched from a simple REST API. So i'm grabbing the JSON object in the RanjoorExplore class and the data is sent into the data to the ExploreCard in the other class. So the this.props.data must be referencing the passed variable. By mapping that variable, I'm displaying the title attribute of the response object in a simple Text Component.

Thanks in advance.

https://jsonplaceholder.typicode.com/posts/1 returns an object, not an array. Therefore, map is not a valid operation
Perhaps you meant to use https://jsonplaceholder.typicode.com/posts/? That returns an array

React Native release a letter is missing

I watched a tutorial about React Native on YouTube.
I have built a simple stopper app. (Android) The problem is, in the release build, one of the letters is missing. I tried to build another simple app with just having "Hello" and in the release build in my phone instead of showing "Hello" I get "Hell".
Pictures:
Development build using Nexus 6 (AVD):
Release build with LG G4 (physical):
I don't know why this is happening. I appreciate any advice and help.

},
startButton: {
borderColor: '#2ecc71'
},
lapButton: {
borderColor: '#1abc9c'
}
})
AppRegistry.registerComponent('flexbox', () => flexbox)

You haven't supplied any code, but I'm guessing you have created a view with exact width and height, and in order to have the text in the middle, you added padding.
Here's an example of a working circle with text:
import React, { Component } from 'react';
import { Text, View, StyleSheet } from 'react-native';
export default class App extends Component {
render() {
return (
<View style={styles.container}>
<View style={styles.circle}>
<Text>Hello</Text>
</View>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
alignItems: 'center',
justifyContent: 'center',
backgroundColor: '#ecf0f1',
},
circle: {
width: 50,
height: 50,
borderRadius: 25,
justifyContent: 'center',
alignItems: 'center',
borderColor: 'red',
borderWidth: 3,
}
});

why input field not display full width in android?

I am using react-native .My input field is not display on full width why ? But when I check on IOS it works correctly display input field on full width .
here is my code
https://rnplay.org/apps/aHRkHA
import React from 'react';
import {
registerComponent,
} from 'react-native-playground';
import {
StatusBar,
StyleSheet,
Text,
TextInput,
View,
} from 'react-native';
class App extends React.Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.heading}> Login</Text>
<TextInput
style={styles.loginInput}
placeholder="Type here to translate!"
/>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
backgroundColor: '#EF501E',
flex: 1,
alignItems: 'center'
},
logo: {
width: 50,
height: 50
},
heading: {
fontSize: 30,
marginTop: 20
},
loginInput: {
height: 50,
borderWidth: 1,
borderColor: '#33090C',
flexDirection: 'row',
justifyContent: 'center',
}
});
registerComponent(App);

Try overriding the alignItems: 'center' of the parent with alignSelf: 'stretch' for <TextInput>:
<View style={styles.container}>
...
<View style={{alignSelf: 'stretch'}}>
<TextInput
style={styles.loginInput}
placeholder="Type here to translate!"
/>
</View>
</View>
