Need to show the long text, which is retrieved from server.
I'm using web storm and react native 0.57
<Text>{this.state.responseText}</Text>
Should be able to view long text under the text tag. Why long text is not shown under Text component?
Yes, I was also facing same problem. Use WebView instead of text component.
<WebView
originWhitelist={['*']}
source={{html: this.state.responseText}}}
/>
I think you should use numberOfLine = {} property of text component.
you can edit style of your text component and make fontsize larger
<Text style={{fontSize: 40}}>{this.state.responseText}</Text>

I'm using the React Native Base Button.
The fontSize prop doesn't seem to work at all, it doesn't do anything. Am I doing something wrong, or misunderstanding the prop?
I did install the library using --legacy-peer-deps, because it doesn't offically support React 18 yet, but it seems to be working fine outside of this.
It appears you can pass props to the underlying Text in the Button with the _text prop:
<Button _text={{fontSize: "2xl"}}>
Press Me
</Button>
You are trying to increase Button's font size that is why it is not working. Think about that you try to increase TouchableOpacity's font size.
Here is a possible Solution
<Button>
<Text style={{fontSize:16}} >Button Title</Text>
</Button>
I have an Image of the body I am using a <Image> Component for that, and I have to mark wound on the body Image, but the thing is I have used <TouchableOpacity> for gain touch on the Image. Please Help me out on this. Thanks in advance.
I'd suggest you use react-native-svg to render a path instead .. which will allow you to handle onPress event for the path
<Svg {/**props */}>
<Path
d="..." /** Path */
onPress={() => alert('Pressed!')}
/>
</Svg>
It'll also give you sharper looking image...
The onPress handler of TouchableOpacity receive a PressEvent as parameter. This object contains information about the press location.

I have a detailspage in my RN app with a component called imagescrollview https://github.com/bamlab/react-native-image-header-scroll-view and i want the header image to be a swipable slideshow and I found this package https://www.npmjs.com/package/react-native-image-slider and i am trying to include it into the renderHeader function of the first package.
But the problem is that the slideshow is not clickable because it is inside the headerimagescrollview.
i've tried to set the imageSlider with zIndex: 1 but that doesn't help, i cant set the position to absolute because the image will dissapear.
<HeaderImageScrollView
maxHeight={180}
minHeight={80}
fadeOutForeground
maxOverlayOpacity={0.5}
minOverlayOpacity={0.0}
renderHeader={() => (
<ImageSlider
images={[
ActivityFoto + this.state.dataSource.Foto,
'http://placeimg.com/640/480/any',
'http://placeimg.com/640/480/any'
]}
/>
)}
Did you try to wrap the components with a touchableOpacity. I've a similar case but i'm using react-native-snap-carousel and it's working fine with the touchableOpacity
Use keyboardShouldPersistTaps='always' in all of the click enabled parent (scrollView/Flatlist/TouchableOpacity etc)components then it will work.
I'm having trouble force focussing a react native TextInput field.
It's focused when the page loads with autofocus={true}.
But after blurring I would need to press the text input field, but that's hidden because of design reasons. Is there a way to document.getElementById("myText").focus(); in react native that I can call after onBlur()?
Cheers.
You need to assign the TextInput field to a ref like this:
<TextInput ref={ref => (this.ref = ref)} />
Then you can programmatically focus it by running focus() on it, like so:
this.ref.focus();
Here's a little Snack where I run the focus/blur function when pressing a button:

It should be easy to replicate this for your navigation scenario.
In case you're using react-navigation, this is the part of the docs you'll be interested in: https://reactnavigation.org/docs/en/navigation-prop.html#addlistener-subscribe-to-updates-to-navigation-lifecycle
I am using Tcomb Form Native for forms and putting auto tag for placeholder in the options. However I would like to change the style for the text displayed. Is it possible to change that ?
var options = {
auto: 'placeholders',
};
<TextInput/> takes a prop of placeholderTextColor additionally the placeholder text should inherit whatever styles you put on the TextInput see the following example here: https://rnplay.org/apps/Yyfuag
