actually, I am designing a simple form page, I am struggling while handling keyboard, Yes I have also seen react native docs, in that they have suggested me to use Keyboardavoiding view but that makes the layout even worse so, can anyone tell how to handle the issue
Im think the virtual keyboard is affecting your width and height, instead of using percentages for your width and height, you can try using dimensions:
var windowWidth = Dimensions.get('window').width;
var windowHeight = Dimensions.get('window').height;
width: width * 0.5
height: height * 0.07

I want to be able to press on the searchbar icon of my search bar and have it acting the same way as if I had pressed on the placeholder of my search bar. So when I press the icon it must show my keyboard, etc... I tried to search on how to do it but I didn't get any result. Here is my current code:
<View style={{zIndex: 99}}>
<Searchbar
style={{borderRadius: 100, height: 35, backgroundColor: '#FAFAFA', elevation: 0, width: 0, top: 185, left: 180}}
placeholder='Search post '
placeholderTextColor='#E0E0E0'
iconColor="grey"
fontSize={5}
/>
</View>
You can use useRef to achieve this. doc
For Example:
const ref = React.useRef(null);
return (
<View style={{marginTop:100}}>
<Searchbar
placeholder="Search post"
placeholderTextColor='#E0E0E0'
onChangeText={onChangeSearch}
value={searchQuery}
iconColor="grey"
onIconPress={()=>ref.current.focus()}
ref={ref}
/>
Try it on expo
(I'm testing on Android if it matters)
I'm using the component KeyboardAwareScrollView to make the inputs visible while the soft keyboard is open. I have two inputs, one below the other, and when I press the top one, the soft keyboard does make sure it's visible but also hides the one below.
Is there a way to make sure that when the keyboard is open, the two inputs will remain visible, even if the user pressed the one at the top?
My code:
<KeyboardAwareScrollView scrollEnabled={false} resetScrollToCoords={{ x: 0, y: 0 }}>
<Image {...this.image.header} style={{ height: 400, width: '100%' }} />
<View>
<TextInput style={{ backgroundColor: 'red' }} />
<TextInput style={{ backgroundColor: 'blue' }} />
</View>
</KeyboardAwareScrollView>
I am copying this answer of boredgames.
<TextInput
placeholder = "FirstTextInput"
returnKeyType = { "next" }
onSubmitEditing={() => { this.secondTextInput.focus(); }}
blurOnSubmit={false}
/>
<TextInput
ref={(input) => { this.secondTextInput = input; }}
placeholder = "secondTextInput"
/>
I created 2 Views that display overlaps to each others. The top and the bottom
When the bottom view background wasn't configured. It responded to the press event correctly. Let's say when I press on the overlap zone, it showed that the bottom one had been pressed
However, when I configured the bottom view backgroundColor. When I pressed on the overlap zone, on Android, it responded as I pressed on the top view which I think it's incorrect. (iOS it responded correctly that the bottom was pressed)
Steps To Reproduce
Provide a detailed list of steps that reproduce the issue.
Here is an example component
const OverlapseTouchExample = ({backgroundColor}) => {
const [pressedBox, setPressefBox] = React.useState('')
return (
<View>
<Text>{pressedBox} pressed</Text>
<TouchableOpacity style={[styles.box, {backgroundColor: 'blue'}]} onPress={() => setPressefBox('top')} />
<View style={backgroundColor ? { backgroundColor: 'orange' } : null}>
<View style={{marginTop: -75}}>
<TouchableOpacity style={[styles.boxBottom, backgroundColor ? { backgroundColor: 'green '} : null]} onPress={() => setPressefBox('bottom')} />
</View>
</View>
</View>
);
}
const styles = StyleSheet.create({
box: {
width: 150,
height: 150,
borderWidth: 1,
},
boxBottom: {
width: 120,
height: 200,
borderWidth: 1,
}
})
The problem found when set the backgroundColor to true
<OverlapseTouchExample backgroundColor={true} />

I am using rn-bottom-drawer for drawer implementation for my app. I tried several ways like PixelRatio, ModerateScale, If-else for range of screen height but i am unsuccessful in setting such a containerHeight that it works perfectly with all device screens and there is no space between my drawer and bottom of my screen.
My Code:
<BottomDrawer
ref={"_drawer"}
containerHeight={moderateScale(270)}
startUp={false}
backgroundColor={null}
downDisplay={moderateScale(200)}
onExpanded={() => this.setState({ isRecentSearchesExpanded: true })}
onCollapsed={() => this.setState({ isRecentSearchesExpanded: false })}
>
<View style={{
width: screenWidth,
}}>
<ImageBackground source={require('../../assets/tabBkgd.png')} style={{ height: "100%", width: screenWidth, justifyContent: "center", backgroundColor: "transparent" }} resizeMode="stretch">
{/* some views here */}
</ImageBackground>
</View>
</BottomDrawer>
This is the package i use for dynamic heights and widths :
rn-responsive.
Basically what you have to do is check in your phone what height suits well. Suppose you get 80 and your deviceHeight is 640 , then all you need to do is calculate (80/640)*100 i.e 12.5 so now
Just do :
import {widthPercentageToDP as wp, heightPercentageToDP as hp} from 'react-native-responsive-screen';
<BottomDrawer
ref={"_drawer"}
containerHeight={hp("12.5%")}
and its fixed. Hope it helps. feel free for doubts
I have a TextInput with multiLine true. However, after two lines the text disappear behind the keyboard. I have tried wrapping the TextInput in KeyboardAvoidingView, but it doesn't work.
The keyboard does push up the TextInput when I unfocus the TextInput and then click on the bottom line. Any idea how I can make the last line of the TextInput stay on top of the keyboard?
The code:
<View style={styles.descriptionFlexStyle}>
<Text
style={[
styles.headerTextStyle,
{ marginTop: Window.height * 0.04 }
]}> Please fill in a reason </Text>
<ScrollView>
<TextInput
style={styles.reasonTextInput}
placeholder="Reason"
value={reasonText}
multiline={true}
onChangeText={input =>
this.setState({
reasonText: input
})
}
underlineColorAndroid="transparent"
ref="reasonTextInput"
/>
</ScrollView>
</View>
hello my dear you must use KeyboardAvoidingView Component from React-Native and put a behavior on it like below :
<KeyboardAvoidingView behavior={'postion' || 'height' || 'padding'}>
<View style={styles.descriptionFlexStyle}>
<Text
style={[
styles.headerTextStyle,
{ marginTop: Window.height * 0.04 }
]}> Please fill in a reason </Text>
<ScrollView>
<TextInput
style={styles.reasonTextInput}
placeholder="Reason"
value={reasonText}
multiline={true}
onChangeText={input =>
this.setState({
reasonText: input
})
}
underlineColorAndroid="transparent"
ref="reasonTextInput"
/>
</ScrollView>
</View>
</KeyboardAvoidingView>
This answer may be a little too late. However, I have found a workaround without using the KeyboardAvoidingView component. A ScrollView could be used instead to scroll the multiline TextInput to the top to have the 'keyboard avoiding' effect. I would use the ref measure() method to get the top y value of the TextInput, before using the scrollTo() method to scroll the TextInput directly to the top of the screen, effectively avoiding the keyboard.
import React, { useRef } from "react";
import { ScrollView, TextInput, View } from "react-native";
export default function Test() {
const scrollViewRef = useRef(null);
const viewRef = useRef(null);
const handleFocus = () => {
viewRef.current.measure((x, y) => {
scrollViewRef.current.scrollTo({ x: 0, y });
});
};
return (
<ScrollView ref={scrollViewRef}>
{/* View to fill up space */}
<View
style={{
width: "80%",
height: 600,
}}
/>
<View ref={viewRef}>
<TextInput
onFocus={handleFocus}
multiline={true}
style={{
width: "80%",
height: 100,
backgroundColor: "whitesmoke",
alignSelf: "center",
}}
/>
{/* View to fill up space */}
<View
style={{
width: "80%",
height: 600,
}}
/>
</View>
</ScrollView>
);
}
Ok i have finally solved it using "KeyboardAvoidingView". I did two things. First i removed the height on my TextInput and then i set the behavior attribute on the "KeyboardAvoidingView" to "padding". Works perfect for me now. Let me know if this help! :)
