I am building a react native app using crna/expo. I want to display an image that already uploaded from API. Since the image is uploaded, I need to use require instead of uri as a source. But I failed to call the image when I put this code:
<Image source={{require('this.state.user.picture')}} style={{ width: 75, height: 75, borderRadius: 37.5 }} />
Also when I changed it to uri, it didn't show anything either.... (not error tho)
<Image source={{uri:this.state.user.picture}} style={{ width: 75, height: 75, borderRadius: 37.5 }} />
Can anyone please help me? Thank you so much!
If your answer is a data type image, you have to do like this:
// include at least width and height!
<Image
style={{
width: 51,
height: 51,
resizeMode: 'contain',
}}
source={{
uri:
'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg==',
}}
/>
changing the uri with your this.state.user.picture
Use `` for call images from variables
<Image style={{ width: 50, height: 200 }}
source={{ uri: `${item.image}` }} />
what I suggest is that modify type according to some condition for eg.
note: require need d local path of image and uri require http link
let image = {uri:this.state.user.picture};
if(something){
image = require('../../demo.jpg');
}
<Image source={image} style={{ width: 75, height: 75, borderRadius: 37.5 }} />
The problem in your code is that you are using double curly braces, when you only need one pair.
Try like that:
<Image source={require('this.state.user.picture')} style={{ width: 75, height: 75, borderRadius: 37.5 }} />
Remember that the double curly braces are just an object literal inlined in the prop value.
I was getting the same behavior. Just adding a width and height to the image worked for me.

I have to achieve Below output :
What I achieved
Here is My source code :
return (
<ImageBackground source={require('../../assets/images/home_bg.png')} style={{
height: 185,
width: '100%',
}}>
<Header style={{
backgroundColor: 'transparent'
}}
androidStatusBarColor={"#EB7D16"} >
<View style={{ flex: 0.5, alignItems: 'center', alignContent: 'center', alignSelf: 'center' }}>
<Left>{LeftIcon}</Left>
</View>
<View style={{ flex: 4, justifyContent: 'center', alignItems: 'center' }}>
<CustomSearchBar />
</View>
<View style={{ flex: 0.5, alignContent: 'center', alignItems: 'center' }}>
<Right>{RightIcon}</Right>
</View>
</Header>
<View style={{ alignItems: 'center', justifyContent: 'center' }}>
<Image resizeMode="contain" source={require('../../assets/icons/logo.png')} style={{ height: '50%', width: '50%', marginTop: 20 }}>
</Image>
</View>
</ImageBackground >
);
I used Image Background and then Set Header component on that module.
Here, I set ImageBackground height: 185, width: '100%', which is wrong way and it's not responsive for all devices. I also use windows.height and windows.width but it's also not working, Kindly share proper way for setting this background Image and How to achieve may targeted output.
Thank you in advance!
you need to make status bar "translucent" so that background image starts from top.
try this and add in your main render of screen
import { StatusBar } from "react-native";
...
<StatusBar translucent backgroundColor="transparent" />
I resolved it by my slef.. actually issue with background image.
Thank you all for time!
I am bringing in an image on my RN app. It's an image of the Simpsons family. When I set the width and height to 100%, the image becomes too big for my simulator. I want it to be centered and formatted to the center of my screen. However, when I adjust the percentages, the image starts getting cutoff (obviously). Another thing, the image itself is not centered despite me stating it in the code (see below). Do any of you have any recommendations? This png image is going on top of a background image already (jpeg).
<Image
source={{
uri:"https://upload.wikimedia.org/wikipedia/en/0/0d/Simpsons_
FamilyPicture.png"
}}
style={{ width: 100 , height: 120, justifyContent: "center", alignContent: "center" }}
/>
Try change resizeMode for contain.
justifyContent and alignContent needs to be style attributes of the container. Something like this:
<View style={{flex: 1, flexDirection: 'column', justifyContent: "center", alignContent: "center"}}>
<Image
source={{
uri:"https://upload.wikimedia.org/wikipedia/en/0/0d/Simpsons_
FamilyPicture.png"
}}
style={{ width: 100 , height: 120}}
/>
</View>
The problem I'm having is that the image inside the image, is on top of the outside image, the outside image is a half transparent image so I want it to be ON TOP of the nested image, as an overlay image, what can I do?
<Image
style={it}
source={require('../../img/Rarities/red.png')}
>
<View>
{
item[2] != null ?
<View style={{ width: 15, height: 15, backgroundColor: item[2].Color }} />
: null
}
<Image
style={{height:'70%',width:'70%'}}
source={{ uri: item[1].base64 }}
/>
</View>
</Image>
I tried:
changing the zIndex of the images didn't work..
In React Native, components are rendered in the order they are defined - therefore it can be tricky to reverse the order and render a parent on top of a child.
Instead, you can render the images as siblings, and use a parent container component with a little position: absolute trickery to get the images to align on top of each other.
For the following view structure:
<View style={styles.imageContainer}>
<Image source={{uri: image1}} style={styles.bottom} />
<Image source={{uri: image2}} style={styles.top} />
</View>
You can achieve this effect with following styles. See inline comments for explanation:
const styles = StyleSheet.create({
// The container controls the top image size
imageContainer: {
width: 200,
height: 200
},
bottom: {
// horizontal margin: (100% -width) / 2
marginHorizontal: '15%',
// vertical margin: (100% - height) / 2
marginVertical: '15%',
width: '70%',
height: '70%'
},
top: {
// positioned absolutely
position: 'absolute',
opacity: 0.5,
// full width/height of imageContainer
width: '100%',
height: '100%'
},
});
You can see it in action in this Snack demo.
I'm not sure that i understand what are you meaning correctly but you can use the Image components like this if you want to have them inside each other:
<View>
<Image
style={{flex:1}}
source={require('./img/favicon.png')}
/>
<Image
style={{height:'30',width:'30', position:'absolute'}}
source={require('./img/favicon.png')}
/>
</View>
Note: the Image sources and the dimensions should be replaced.
I'm developing an app with React-Native.
I want to put an icon on right-bottom corner of an image component, but it always stays on the left-top corner.
Any help? Thank you very much.
<Image source={imageSource} style={{position: "absolute", bottom: 0, right: 0}}/>
You can use justifyContent: 'flex-end' to achieve this:
const withWatermark = (asset, logo) => (
<Image style={{ width: 200, height: 200, justifyContent: 'flex-end' }} source={asset}>
<Image style={{ width: 20, height: 20, alignSelf: 'flex-end' }} source={logo} />
</Image>
);
You can do something like this...
Use this : position: "absolute", bottom: 0, alignSelf: "flex-end"
<ImageBackground
source={require("../assets/homeAssets/3.jpg")}
style={{
height: 140,
width: 140,
resizeMode: "contain",
alignItems: "center"
}}
imageStyle={{ borderRadius: 70 }}
>
<View
style={{
height: 50,
width: 50,
borderRadius: 25,
backgroundColor: "#99AAAB",
alignItems: "center",
justifyContent: "center",
position: "absolute", //Here is the trick
bottom: 0,
alignSelf: "flex-end"
}}
>
<Entypo name="camera" size={25} color="#FFF" />
</View>
</ImageBackground>
I am trying to add the image from Parse to React Native Project.
Everything is ok with adding text:
<Text style={{flex: 1, fontSize: 14, textAlign: 'justify', color: 'black', }}>
{this.props.tweet.get('username')}
</Text>
But I can not add an image:
<Image source={this.props.tweet.get('photo')}
style={{width: 50, height: 50}}/>
I am also trying
var photo = this.props.tweet.get('photoprofile');
....code
<Image source={{uri: {photo}}}
style={{width: 50, height: 50}}/>
And
var photo = this.props.tweet.get('photoprofile');
....code
<Image source={photo}
style={{width: 50, height: 50}}/>
It does not work.
Everything work!!!
var imageFile = this.props.tweet.get('photoprofile');
var imageURL = imageFile.url();
...code
<Image source= {{uri: imageURL}}
style={{width: 50, height: 50}} />
