I have a problem when I try to render an image inside the React Native Maps Callout.
The image does not render.
{this.state.database.map((route, idx) => {
if (route.Image) {
return (
<MapView.Marker
coordinate={{ latitude: Number.parseFloat(route.Latitude), longitude: Number.parseFloat(route.Longitude) }}
key={idx}
image={img_pin}
ref={(ref) => this.marker = ref}
>
<MapView.Callout tooltip style={{ flex: 1, backgroundColor: 'white' }}>
<View style={{ flexDirection: 'row' }}>
<View style={{ flex: 1 }}>
<Text style={styles.textCallout}>Latitude: {route.Latitude}</Text>
<Text style={styles.textCallout}>Longitude: {route.Longitude}</Text>
<Text style={styles.textCallout}>Status: <Icon name={route.Status === 1 ? 'checkmark-circle' : 'close-circle'} style={{ color: route.Status === 1 ? 'green' : 'red', fontSize: 16 }} /> </Text>
<Text style={styles.textCallout}>Velocidade: {route.Speed} km/h</Text>
</View>
<View style={{ margin: 5 }}>
<Image source={{ uri: `data:image/gif;base64,${route.Image}` }} style={{ width: 150, height: 100 }} />
</View>
</View>
</MapView.Callout>
</MapView.Marker>
);
}
})}
Image error don't render inside Callout
"react-native": "^0.57.8",
"react-native-maps": "^0.24.2",
Use Image inside Text component
<Text> <Image style={{ height: 100, width:100 }} source={{ ... }} resizeMode="cover" /> </Text>
Another workaround by using WebView. I think is the proper solution for this right now.
<View>
<WebView style={{ height: 100 , width: 230, }} source={{ uri: ... }} />
</View>
Make sure your route.image is in the form of url schema,
exampleData
source={{uri: 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg=='}}
if correct,
GIF and WebP support on Android
When building your own native code, GIF and WebP are not supported by default on Android.
You will need to add some optional modules in android/app/build.gradle, depending on the needs of your app.
build.gradle:
dependencies {
// If your app supports Android versions before Ice Cream Sandwich (API level 14)
implementation 'com.facebook.fresco:animated-base-support:1.10.0'
// For animated GIF support
implementation 'com.facebook.fresco:animated-gif:1.10.0'
// For WebP support, including animated WebP
implementation 'com.facebook.fresco:animated-webp:1.10.0'
implementation 'com.facebook.fresco:webpsupport:1.10.0'
// For WebP support, without animations
implementation 'com.facebook.fresco:webpsupport:1.10.0'
}
Usage
<MapView.Callout tooltip={true} style={{ backgroundColor: 'white', height: contentHeight, width: contentWidth }}>
<View style={{ flexDirection: 'column' }}>
<View style={{ flex: 1 }}>
<Text style={styles.textCallout}>Latitude: {route.Latitude}</Text>
<Text style={styles.textCallout}>Longitude: {route.Longitude}</Text>
<Text style={styles.textCallout}>Status: <Icon name={route.Status === 1 ? 'checkmark-circle' : 'close-circle'} style={{ color: route.Status === 1 ? 'green' : 'red', fontSize: 16 }} /> </Text>
<Text style={styles.textCallout}>Velocidade: {route.Speed} km/h</Text>
</View>
<Image source={{ uri: `data:image/gif;base64,${route.Image}` }} style={{ width: 150, height: 100, resizeMode="cover" }} />
</View>
</MapView.Callout>

It's either there at the scroll end or does not appear to be floating.

This request is a basic CSS knowledge.
Add position: 'relative' to the styles of the area that should snap under.
Add position: 'absolute' to your button styles. And your wish will come true.

I want to fix an icon inside <ScrollView at right bottom as shown below
But currently , the + icon is moving along with other contents. I want it to be fixed at that position even when other contents go down in the background. Current behaviour
Tried solution :
I used contentContainerStyle={{flexGrow :1}} in the ScrollView , still it doesnt work .
It works when I add the icon outside ScrollView. But it doesn't give expected results which is shown below it cuts the scrolliew content right above the icon:
Can anyone suggest with good solution for this scenario?
Code :
<ScrollView>

We can't see from your code sample where you are calling the second step "upload cnic picture". It seems that you are calling another modal on top of the first one.
If you have planned to have a full process within this modal, it is probably best to integrate a proper navigator rather than "navigate" between modals.
I am using Webview component in React Native to render HTML content. The problem I am facing is that I cannot make the height variable so it can adapt to any content it has.
return (
<View style={{flex: 1}}>
<Header
containerStyle={{
backgroundColor: 'white',
borderBottomColor: '#dee0e2',
borderBottomWidth: 1
}}
centerComponent={{ text: 'Noticia', style: { color: 'black' } }}
leftComponent={
<TouchableHighlight onPress={() => navigate('homeScreen')}>
<Text style={{color: '#4289f4'}}>Atrás</Text>
</TouchableHighlight>
}
/>
<ScrollView style={{padding: 5}}>
<View style={{flexDirection: 'column'}}>
<Text style={{textAlign: 'center', fontSize: 17, fontWeight: 'bold'}}>{noticia[0].titulo}</Text>
<Image style={{width: '100%', height: 200, alignSelf: 'stretch', marginTop: 10}} source={{uri: noticia[0].imagen}} />
<View style={{height: 200, backgroundColor: 'red'}}>
<WebView
source={{html: noticia[0].articulo}}
scalesPageToFit={(Platform.OS === 'ios') ? false : true}
/>
</View>
</View>
</ScrollView>
</View>
);
If I don't give the <View>' that contents ' <Webview>' a height it does show me nothing. Tried already withflex: 1` but nothing changes.
In your parent view (root view directly under return()) style it as
height: '100%',
width: '100%'
It will adopt to any size screen.

First and not the recommended approach will be tu use your index you get as second argument in your .map callback
<View style={styles.contanier}>
{this.props.data.map(function(videoData, index) {
console.log(videoData, "fetch3");
return (
<View key={index} style={styles.card_contanier}>
But using index is not recommended. If you have an id coming from your backend I will use it. This can cause problem with animation and thing like that if you use index.
<View style={styles.contanier}>
{this.props.data.map(function(videoData, index) {
console.log(videoData, "fetch3");
return (
<View key={videodata.id} style={styles.card_contanier}>
You can read about all this here https://reactjs.org/docs/lists-and-keys.html#keys
And article here about why not use index https://medium.com/#robinpokorny/index-as-a-key-is-an-anti-pattern-e0349aece318
