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>
I am using flatlist to render some items collected from firestore and I have a problem with ListHeaderComponent prop.
The header is placed to the left and I need to place it on the top of the 1st item (see 2nd image below) and when moved it has to be fixed with the first item of the list as the image.
Currently
Horizontal flatlist with ListHeaderComponent on the left
I need to achieve this when scrolling left:
Horizontal flatlist with ListHeaderComponent on the top of 1st item
You can separate header text from FlatList. Use Text apparently to show the header.
EDIT
If you want to scroll text with a list you can use FlatList inside ScrollView. In this case, you may disable scrolling for FlatList. Please check below for detail.
<ScrollView horizontal>
<Text>Header Text</Text>
<FlatList scrollEnabled={false} />
</ScrollView>
Okay, solved! Here's the code:
<ScrollView horizontal={true}
<View>
<Text>Header Text</Text>
<FlatList horizontal={true}
scrollEnabled={false} />
</FlatList>
</View>
</ScrollView>
Thank you #baymax :)
React Native's TextInput has a clearButtonMode property which would display a small x button on the right of the input area in iOS through which text can be cleared.
I am having issues with the hit slop of that button. I believe it is too small and easy to miss. I have to press multiple times in order to hit the right spot in order to activate it.
Is there a way to customize this clear button => change its hitSlop, color, etc?
What you could do, is to wrap your TextInput element with view and Animated.View, so you can add your own Clear Button with TouchableOpacity for example, and select an icon, colors, size, etc.
So, basically, it would be something like this:
<Animated.View style={...}>
<TextInput value={...} style={...} onChangeText={...} />
<TouchableOpacity>
{/* HERE GOES YOUR CLEAR BUTTON, FOR EXAMPLE: */}
<MaterialIcons size={24} color={'black'} name={'close'} />
</TouchableOpacity>
</Animated.View>
I have a code like this:
<View>
<View></View>
<ScrollView>
<View>
<TextInput/>
</View>
</ScrollView>
<View></View>
</View>
How can I handle it to response correctly to keyboard?
Both android and ios???
i have 2 permenant views top and bottom of the screen, this views pushed up on keyboard show
Your question is really unclear, but what I think you need is KeyboardAvoidingView.
It's a built-in React Native component that resizes based on the keyboard height.
To make sure the keyboard is not overlapping any important bits of your layout such as your text Input wrap your whole screen in KeyboardAvoidingView

Solved!!
I solved it by handling the display of elements (views) on keyboard show and hide by keyboard in react native docs
I'm new to React Native, so am probably asking something very obvious, but please help.
I have a view wrapped in a touchable, so that the whole area responds to tapping. Then have a ScrollView nested inside the view. The overall structure is something like this:
<TouchableWithoutFeedback onPress={this.handlePress.bind(this)}>
<View>
<ScrollView>
<Text>Hello, here is a very long text that needs scrolling.</Text>
<ScrollView>
</View>
</TouchableWithoutFeedback>
When this compiles and runs, the tapping is detected, but the scroll view doesn't scroll at all. I made the above code short and simple, but each component has the proper styling and I can see everything rendering fine and the long text is cutoff at the bottom of the ScrollView. Please help.
Thank you!
This is what worked for me:
<TouchableWithoutFeedback onPress={...}>
<View>
<ScrollView>
<View onStartShouldSetResponder={() => true}>
// Scrollable content
</View>
</ScrollView>
</View>
</TouchableWithoutFeedback>
The onStartShouldSetResponder prop stops the touch event propagation towards the TouchableWithoutFeedback element.
I'm using this structure it's working for me:
<TouchableWithoutFeedback onPress={() => {}}>
{other content}
<View onStartShouldSetResponder={() => true}>
<ScrollView>
{scrollable content}
</ScrollView>
</View>
</TouchableWithoutFeedback>
You can have a scrollView or FlatList inside a TouchableWithoutFeedback. Tho you shouldn't but some times you have no other choice to go. Taking a good look at this questions and answer validates that.
close react native modal by clicking on overlay,
how to dismiss modal by tapping screen in react native.
For the Question, The only way you can make it work (atleast that i know of), or the simplest way is to add a TouchableOpacity around Text in your code like this,
<TouchableWithoutFeedback onPress={this.handlePress.bind(this)}>
<View>
<ScrollView>
<TouchableOpacity>
<Text>Hello, here is a very long text that needs scrolling.</Text>
</TouchableOpacity>
<ScrollView>
</View>
</TouchableWithoutFeedback>
Note: TouchableOpacity is a wrapper for making Views respond properly to touches so automatically you can style it the way you would have styled your View Component then set some of its special props to whatever you want e.g activeOpacity etc. Moreso you can use TouchableHighlight it works, but it receives one child element i.e you enclose all your component inside a parent one.
I'm using this structure it's working for me:
<TouchableOpacity>
{other content}
<ScrollView>
<TouchableOpacity activeOpacity={1}>
{scrollable content}
</TouchableOpacity>
</ScrollView>
I found that for my situation the other examples did not work as they disabled the ability to click or disabled the ability to scroll. I instead used:
<FlatList
data={[{key: text1 }, { key: text2 } ...]}
renderItem={({ item }) => (
<TouchableWithoutFeedback onPress={this.onPressContent}>
<Text style={styles.text}>{item.key}</Text>
</TouchableWithoutFeedback>
)}
/>
I happend to need to multiple chunks but you could use single element in the data array for one piece of text.
This let the press event to fire as well as let the text scroll.
Trying to use a ScrollView component inside a TouchableWithoutFeedback component can cause some unexpected behavior because the TouchableWithoutFeedback component is designed to capture user gestures and trigger an action, but the ScrollView component is designed to allow users to scroll through content.Here is what the official docs say
Do not use unless you have a very good reason. All elements that
respond to press should have a visual feedback when touched.
TouchableWithoutFeedback supports only one child. If you wish to have
several child components, wrap them in a View. Importantly,
TouchableWithoutFeedback works by cloning its child and applying
responder props to it. It is therefore required that any intermediary
components pass through those props to the underlying React Native
component.
Thats write , you cannot have a scroll view inside the TouchableWithoutFeedback, it the property of react native that it will disable it, you can instead have your scroll view outside the TouchableWithoutFeedback tab and add the other contents that you want upon the click inside a view tag.
You can also use the Touchable Highlights instead, if the TouchableWithoutFeedback does not works.
