How to add margin: 1
perfectly in my Camera Roll? Because when I add margin: 1
in my <Image .../>
the order will not be in correct order.
The result I want is like in the Instagram. There's no margin in the Left and Right Side, right?
Just like this Image:
Here are my Codes:
render() {
return(
<View style={styles.container}>
{/* <SelectedImage source={{uri: this.state.pickedImage}}/> */}
<Image source={{uri: this.state.pickedImage}} style={styles.image}/>
<ScrollView contentContainerStyle={styles.scrollView} showsVerticalScrollIndicator={false}>
{this.state.photos.map((photos, index) => {
return(
<TouchableHighlight
style={{opacity: index === this.state.index ? .5 : 1}}
onPress={() => this.setState({pickedImage: photos.node.image.uri})}
key={index}
underlayColor='transparent'
>
<Image
style={{width: width / 3, height: width /3}}
source={{uri: photos.node.image.uri}}
resizeMode='cover'
/>
</TouchableHighlight>
);
})}
</ScrollView>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
height: '100%',
width: '100%',
justifyContent: 'center',
alignItems: 'center',
backgroundColor: 'white'
},
scrollView: {
flexWrap: 'wrap',
flexDirection: 'row'
},
scrollViewContainer: {
flex: 1,
flexDirection: 'row',
},
image: {
width: '100%',
height: 300,
backgroundColor: 'black'
}
});
This is the Result on my own: (Dont't bother of the Black Border I just didn't crop perfectly and I have just 6 Photos in my Android Emulator).
Answer Suggested:
componentDidMount() {
this.getPhotos();
this.rightButtonIcon();
requestExternalStoragePermission();
photoFilter = () => {
var arr = this.state.photos;
var number = 0;
arr.forEach((item) => {
switch(number) {
case 0:
number = 1;
item.position="left"
break;
case 1:
number = 2;
item.position="center"
break;
case 2:
number = 0;
item.position="right"
break;
default:
return null;
}
})
this.setState({photos: arr})
}
};
imageStylePositionCalc = (pos) =>{
if(pos==="left") return {marginRight:1,marginBottom:1}
if(pos==="center") return {marginRight:1,marginBottom:1}
if(pos==="right") return {marginBottom:1}
}
render() {
return(
<View style={styles.container}>
{/* <SelectedImage source={{uri: this.state.pickedImage}}/> */}
<Image source={{uri: this.state.pickedImage}} style={styles.image}/>
<ScrollView contentContainerStyle={styles.scrollView} showsVerticalScrollIndicator={false}>
{this.state.photos.map((photos, index) => {
return(
<TouchableHighlight
style={{opacity: index === this.state.index ? .5 : 1}}
onPress={() => this.setState({pickedImage: photos.node.image.uri})}
key={index}
underlayColor='transparent'
>
<Image
style={[{width: width / 3, height: width /3}, this.imageStylePositionCalc(photos.position)]}
source={{uri: photos.node.image.uri}}
resizeMode='cover'
/>
</TouchableHighlight>
);
})}
</ScrollView>
</View>
);
}
}
This is the another Problem, the margin: 1 taking over the full width of the screen and there is no margin in the 2nd row:
