I am new to react-native. I want a toggle button with 2 text blocks. How this can be achieved with react native?.
The toggler should animate when clicking buy and sell texts respectively.
Following is the image reference for the design.
You can try this library.
This does not match the design exactly but it's a toggle with two text blocks. If you want something that looks exactly like your image I'm afraid you will have to build it yourself. You could use the mentioned library as a starting point.

I'm looking for a solution, if possible a library or a custom component, for React Native, without Expo.
I need to create a video frame that is movable in the screen, up and down, and cover the content. I also need to make it possible to click on the content behind it.
Another difficulty is that I need it to stay up on all screens during navigation.
I first tried to use reanimated-bottom-sheet with some increments, but the content behind the bottom is not clickable. Also, to make it available on all screens I needed to put in at the same level as React Navigation's BottomTabNavigator and it covers the tab bar too even with a zIndex.
I also tried to use modals, but I'm relatively new to React Native and couldn't find how to make the background touchable as well as making it movable.
I guess I need to make a view with absolute positionning and learn Reanimated, unless you have a simpler idea?
Thanks
I am trying to implement a UI layout similar to google maps "explore" on Android, (see gif) in React Native.
In my UI design I have app navigation tabs at the bottom of the screen, with a full page map background, overlaid with a "bottom sheet" coming from above the tabs, and a search box component at the top. See UI sketch below.
I have found various react-native ui components which look useful, but I can't figure out the styling to arrange them in the layout I want.
Several of the bottomsheet components I'm looking at, for example, rn-bottom-drawer show gifs similar to what I'm trying to create, e.g this animation, but I can't find an actual code example of how that UI was created. For example, the same library example just shows the bottom drawer over an empty screen.
What combination of wrapping elements and styles would allow me to create the layout described? I come from a XAML background and this kind of layout is very easy to create, but I can't get my head around how to do it in react native.
It is halfway possible with the component "react-native-swipe-up-down".
The swipe up above the App works, but it is really buggy. Had the same problem as you and couldn't find anything better than swipe-up-down til today.
I am trying to build a language selection picker in react native which has a picture of the country's flag next to the label, like this:
The icons have to be images and not unicode. I've had a look around but there doesn't seem to be anything available. Does anyone know of anything I can use to create this?
If nothing can be used then I will create a custom picker, I aim to make use of a ScrollView to handle the scrolling but I am not sure what I can use to replicate the rotation effect of the native iOS picker, so if anyone can help me with this also I would really appreciate it.
You can try this:
https://github.com/xcarpentier/react-native-country-picker-modal
It's not inside a native picker like your screenshot, but it should do what you are asking for.
You can use emoji by copy from online emoji website(many available on internet) and add picker item code as below,
<Picker.Item label="🇫🇷 France" value="fr" />
The Yelp app for iOS is designed such that after you enter and send a search query, something like this comes up:
The screen consists of a map control in the background, with a screen on top displaying a list view that you can swipe up/down depending on whether you want to see the list/map (respectively).
How would something like this be accomplished using React Native? For example, would the React Navigation or React Native Swiper libraries help me superimpose a list view on top of the map control?
You can use PanResponder.

Is there any way to build custom camera component in codename one?
I googled and got about PeerComponents, however don't know how to use it.
I just would like to use it as Label component with 2 buttons (Taking picture button and retaking picture button)
Kindly provide some small sample code for me. Best regards.
[UPDATE]
I need this because of following reason.
First of all, I need square Image taken by camera, and user should be able to know how the picture will be taken.
2 resolutions here:
First, if I have to use full screen camera, it will be better to draw or overlay square rectangle on camera view so that user can know which area will be taken.
Second, if overlaying and drawing is difficult (or should use native code for that), I need some custom components for camera area such like PeerComponent. So I would like to place it anywhere of screen area as square rectangle. Then, users won't need any overlay or drawing something on it because it is already square.
That's all what I need.
Regards.
Yes, it's certainly possible to create a component like this, and we do intend to create one at some point in the future. You can beat us to the punch.
First, you should familiarize yourself with how native interfaces work. This video is a good start:

This series of blog posts demonstrates how to wrap 3rd party SDKs into codename one on Android and iOS.

Although it doesn't include an example with PeerComponent, it is helpful for getting a grasp on the process. Adding peer components into the mix is really just a matter of returning the corresponding "View" type from a native interface. On Android, that is an android.view.View, on iOS it is a UIView, in Javascript it is an DOM element, in UWP it is a FrameworkElement, and in the simulator, it is a javax.swing.JComponent.
This blog post does include an example of a peer component, but it is targeting UWP:

Once you have a grasp of the material, you should look at relevant examples. Currently the most complete example I'm aware of of a cn1lib that implements a native peer is the Google Maps lib:
https://github.com/codenameone/codenameone-google-maps
You can see the Android native implementation here, and the iOS native implementation here
You may want to refer to the existing code for image capture in Codename One as well.
Android: https://github.com/codenameone/CodenameOne/blob/master/Ports/Android/src/com/codename1/impl/android/AndroidImplementation.java#L5788-L5811
https://github.com/codenameone/CodenameOne/blob/master/Ports/Android/src/com/codename1/impl/android/AndroidImplementation.java#L5701-L5714
Though it uses intent to open the native capture dialog, so it may not be too relevant.
IOS: https://github.com/codenameone/CodenameOne/blob/master/Ports/iOSPort/nativeSources/IOSNative.m#L2879-L2927
