React Native: Fix TextInput at the bottom of the screen with a ScrollView - react-native

I need to fix the input in the bottom of the screen, so that keyboard pushes this input (similar to instagram comments).
Here's an example():

It's working fine, but if I put the FlatList inside the ScrollView the bottom input is dissapearing.
What's the right way to solve this problem?


try this
<View style={{flex: 1,}} >
<ScrollView>
{content}
</ScrollView>
<TextInput style={{position: "absolute", bottom :0}}/>
</View>

How do I make an absolut positioned touchable element on top of a FlatList catch only press events and let other events propagate to the FlatList?

I have a FlatList in React Native with fullscreen image and video items (with pagingEnabled). I want to have a short descriptive touchable text floating on top of the FlatList, to open up a view with some information about the image/video when pressed.
To make the user experience nice, I'd like to be able to scroll the FlatList through the touchable text as well. I.e. if the user happen to start their scrolling motion on top of the text, the FlatList would scroll but if it is a simple press event I'd like to open the view with details about the image/video.
No mater what I try I end up with either the text being able to react to the press OR the FlatList being able to scroll. I have tried different configurations with a custom PanResponder and pointerEvents but seem to always end up with a state were one thing does not work. Do you guys have any smart ideas? I am probably just stuck in the wrong train of thought.
This is a simplified view of my component structure:
<View>
<View style={{ position: 'absolute', bottom: 100, zIndex: 10 }}>
<TouchableOpacity onPress={() => console.log('press')}>
<Text>Some Descriptive Text</Text>
</TouchableOpacity>
</View>
<FlatList pagingEnabled horizontal {...otherFlatListProps} />
</View>

In bottom half modal, transparent background also sliding along with modal in animationType = "slide" (React Native)

I implemented a bottom half modal view in react native, which is sliding in from the bottom . I set the background of the modal view to transparent so the previous view is still visible, but the modal view is in focus. This is working fine and once it is open it also looks how I want it to look. My problem is, that the transparent background is also sliding in from the background and this does not look like a native implementation at all. What I want to achieve is, that the transparent background just appears while the modal view slides in from the bottom. Any idea on how to solve this?
Note: Iam using Modal from inbuilt react native, hence not using any npm module or package.
My code:
import { View, Text, Modal } from 'react-native';
function DurationModal(props) {
<View>
<Modal
visible={props.isVisible}
transparent
animationType='slide'
statusBarTranslucent
>
<View>
<View style={{ backgroundColor: 'rgba(0,0,0,0.1)', height: hp('60%') }}></View>
<View style={{ backgroundColor: Colors.whiteBackgroundColor, height: hp('40%') }}>
<Text>Hello</Text>
</View>
</View>
</Modal>
</View>
);
}

TouchableOpacity wont work as supposed in android

I got an app with flatlist ,I added to the app TouchableOpacity that covers the whole screen,
works great when I click on item area but doesn't work when I click the area that got no items
this is the code of the TouchableOpacity:
<View style={{position: "absolute",width:'100%',height:HEIGHT,backgroundColor: 'rgba(0,0,0,0.8)',zIndex:6}}>
<TouchableOpacity onPress={()=>setEditing(false)} style={{flex:1,zIndex:6}}>
</TouchableOpacity>
Its looks like the flatlist block any clicks below it also in ios its works without any problems

Try change it to:
<View style={{position: "absolute",width:'100%',height:HEIGHT,backgroundColor: 'rgba(0,0,0,0.8)',zIndex:6}}>
<TouchableOpacity onPress={()=>setEditing(false)} style={{flex:1,zIndex:7}}>
</TouchableOpacity>
</View>
and run it

Can't scroll inside ScrollView, when there are TextInputs

I have ScrollView inside that ScrollView, I have TextInputs, the scroll doesn't work in the area of TextInput. How to fix that?
render () {
return (
<View>
<ScrollView
ref='keyboardScroll'
keyboardShouldPersistTaps={true}
>
<View>
<TextInput
placeholder='First Name'
/>
</View>
<View>
<TextInput
placeholder='Last Name'
/>
</View>
<ScrollView>
</View>
)}
Here is the video with the issue.

I found the solution of that problem. The main problem was that text font size was too big for the TextInput field, which causes scroll inside the TextInput, so there are 2 solutions: 1) decrease font size 2) make the height of the TextInput field bigger. Also this solution solved another problem: Placeholders in TextInput are moving during the scroll

I had the same problem on Android, where the placeholder was scrolling just a little bit up and down and preventing the ScrollView from scrolling. I managed to fix it by adding the following styles on the TextInput:
paddingTop: 0,
paddingBottom: 0,
paddingLeft: <whatever>,
paddingRight: <whatever>

React Native - How do you create a vertical overlay?

I was just wondering if it was possible, in React Native, to create a vertical overlay ; by that, I mean being on a page and when swiping down, an overlay comes down, covering the page, with various information on it (and the same when swiping up, an overlay coming from the bottom). I wanted to use react-native-swiper at first, but the vertical swiping is not compatible with Android.. So if anyone has another solution to offer, be my guest ! Thanks

check react-native-parallax-view hope this can help you.
EDIT
example:
return (
<View style={[{ flex: 1 }]}> {/* add parent container and then ParallaxView as specified in documentation */}
<ParallaxView
backgroundSource={require('image!backgroundImage')}
windowHeight={300}
header={(
<Text style={styles.header}>
Header Content
</Text>
)}
scrollableViewStyle={{ backgroundColor: 'red' }}
>
<View>
// ... scrollview content
</View>
</ParallaxView>
</View>
);
