I have implemented the RefreshControl component which works great, except that when my view initially loads, I see part of another Refresh control showing above the NEW GAME button. Once I pull down, I get my data and the bug disappears until I restart the app. Everything else works great but it seems like the 'title', 'tintColor' and 'titleColor' props are causing the problem, because there is no bug without them.
Here is my code:
<RefreshControl
refreshing={this.state.refreshing}
onRefresh={this.onRefresh}
title={I18n.t('coming')}
tintColor="#dceafd"
titleColor="#dceafd"
/>
Just add backgroundColor: 'transparent', i think :)

I am using this above code and in the Android manifest orientation in portrait. I am click on the full screen state has been changes according to it. But it just exit in a second. As i am getting a little fluctuation and maybe the app is showing full screen and then exit from full screen. But i am not able to see it. Or you can say full screen is not working. As in the IOS it is working properly. I tried multiple from github but not able to achieve it.
On Android, Landscape-Mode works like a charm, but on IOs I've found following issue:
Mobile-Device is in Landscape-Mode:
I click on an Image (Touchable-Opacity set the state modalShow
The Landscape-Mode will be switched to Portrait-Mode, after that the Modal appears
If I close the Modal, the App switch back to Landscape-Mode.
Any Idea, why this only happend on Iphone, but working well on Android?
You have to add this (or only some of them like you're needs) to your Modal, which encapsulate the Image-Zoom Component:
supportedOrientations={
[
'portrait',
'portrait-upside-down',
'landscape',
'landscape-left',
'landscape-right'
]
}
Consider using a library to manage the screen rotation https://github.com/yamill/react-native-orientation
I'm trying to show some images in my React Native app. It's a simple app, only for Android. The app get informations from an API. The initial View is a list of items and when I click in one item, it gets more info from the API and show in a new page. I also get some urls that points to images that are kept in a S3 bucket in AWS.
This is how I show the images:
<ScrollView>
{this.state.urls.map(url => {
<Image
source={{uri: url}}
style={{width:400, height:200}}
/>
}
</ScrollView>
The problem is that it's not showing those images. I can see that there is a part of the page that is for the image. I can see that because if a put the image first and after that some text, the text will appear at the bottom of the page. I don't know what is going on that the image doesn't appear.
I searched for an answer, found something about using https instead of http (at least for iOS). Found that I need to set width and height. I already did those things and others but it's not working.
I also tried just picking a image from the internet and putting it url direct in uri but it still doesnt't work.
You're missing a return statement in your map function.
<ScrollView>
{this.state.urls.map(url => {
return <Image
source={{uri: url}}
style={{width:400, height:200}}
/>
}
</ScrollView>
UPDATE
I just tried the url that you provided in the above comment and it doesn't work on my device. I tried a different image from the internet this one and it works. There may also be something that is stopping you from accessing the images from within a mobile app.
To debug further I try would a single <Image .../> with the image hosted on AWS and see if you can get that to show. There may need to be some AWS configuration that you need to change to allow the image to be accessed from a mobile device.
Assuming your image URLs are accessible in your application.
The below code will show your images. Actually you forgot to return a component from the map which is a must have.
<ScrollView>
{this.state.urls.map(url => {
return <Image
source={{uri: url}}
style={{width:400, height:200}} /> }
}
</ScrollView>
I am trying to find a way to load image reference I get from places api into places photo API using Image component of react-native like below,
const imageLink = 'https://maps.googleapis.com/maps/api/place/photo?maxwidth=400&photoreference=CmRaAAAAuZ36wzrMYCVNWM1smQkRKuQyXecPgRpcsMfrSqbJM0EUTXZ62j8Ljxtk8HsxohXbtAwZAwmj_F3HmDwLoQaH9qt2TZJhhA6EuXK41UFo0Ow750MJujtrr5hgHR2lF7EXEhCkWj_dZ4LefrYzLU1_5RF1GhTR7Ggem5IJ-v7V2U8fjKoU9tBUOg&key=--MyKey--'
return (
<View >
<TouchableHighlight >
<View>
<Image
style={{width:64, height:64,flex:1,backgroundColor:'red'}}
source={{uri: imageLink}}
/>
</View>
</TouchableHighlight>
</View>
);
I am getting only empty placeholder with above code. However, I am able to load this link in browser.One caveat is that google places photo's link is redirecting to some other url which then displays image in browser. Am I doing it right? or is there any other way I can accomplish the same. Note: I tried react-native-network-image library as well.
You can have a look at the ImagePrefetch function in googleplace module:
https://github.com/srirangan/googleplaces.js/blob/master/test/ImageFetchTest.js
However, I am having issue with the whole module at the moment because of the line var https = require("https"); called in this specific function.
Not sure if it's an issue with new version of RN (upgraded to 0.55 recently) or just some other error in my new setup.
This worked perfectly in previous RN (was running on 0.48)
I want to get html in web view.
I read react-native-doc(https://facebook.github.io/react-native/docs/webview.html#content) but I cannot found it.
Can I do this?
None of the answers above worked for me, but this did. It displays the received html content of the webview in the console:
const jsCode = 'window.ReactNativeWebView.postMessage(document.documentElement.innerHTML)'
return (
<WebView
injectedJavaScript={jsCode}
source={{ uri: 'https://www.whatever.com' }}
onMessage={event => console.log('Received: ', event.nativeEvent.data)}
javaScriptEnabled
/>
)
I found this.
https://github.com/alinz/react-native-webview-bridge
But I could not use this in android. This works only in android.
I don't know this problem is only my problem or library problem.
In Android I use onNavigationStateChange.
Read https://github.com/facebook/react-native/issues/586#issuecomment-90826117
I think this is not good way. But I really need this. so I used this.
In case anyone comes across this in the future. You options here is to use javascript. You can use injectedJavaScript on the webview to inject a window.postmessge($('body').html()) and then handle the reply in the onMessage function on the webview. The cleaner way would be to fetch the page yourself and then load it into the webview.
