Getting Started. For simplicity let's remove all content that was created by react-native init, and add below. 21 August 2018 / Android Create Android UI Components for React Native. E.g. Our goal will be to integrate the native material-wheel-view component with the React Native application. We can use any view that already exists in Android like ImageView, VideoView, TextView, LinearLayout or we can implement and use a custom view. These subclasses are essentially singletons - only one instance of each is created by the bridge. Reading Time: 7 minutes In the process of learning and growing as a React Native developer, at some point in your career you’ll get to the point when you get a task that requires more specific/exotic functionality than React Native abstractions can offer at that point of time. Trying out new techniques and technologies is great, so why don’t we try out Kotlin for React Native modules? Call your native SimpleViewManager (MapView) from App.js. This in React Native is known as ViewManager. Native views are created and manipulated by extending ViewManager or more commonly SimpleViewManager. A ViewManager is a React Native interface responsible for instantiating and updating views in the app. React Native is a convenient tool for cross platform development, and though it has become more and more powerful through the updates, there are limits to it, for example its capability to interact with and using the native components. The component is used to select the element in the same way as the one known from the iOS platform. The SimpleViewManager is a generic class that uses our view. With this, you can use JavaScript to build native Windows apps for all devices supported by Windows 10 including PCs, tablets, 2-in-1s, Xbox, Mixed reality devices, etc., as well as the macOS desktop and laptop ecosystems. https://stefan-majiros.com/native-android-fragments-in-react-native Also, this bridge will help us with the user interaction & bringing the user interaction related changes to our React Native code. A bridge is nothing but a way to setup communication between native platform and React Native. You can find a reference to ViewManager in the official guides over here. Here, we have inherited SwitchManager class from SimpleViewManager. Native views are created and manipulated by extending ViewManager or more commonly SimpleViewManager. This will replace whole page with native Google Map. Step-3: Implement createViewInstance method. Once you install React Native, it provides you a lot of built-in components, View is the most fundamental component you can use, and there are others available to build your UI like Text, Image, and some basic others. Here SimpleViewManager is used to expose the Android native view to the React Native code. According to the 0.29.0 upgrade docs, it's now very easy to extend ReactContextBaseJavaModule and use getCurrentActivity to get the activity reference in native Android modules.However, it no longer appears to be possible to get access to the current activity from native Android UI Components.. React Native is developed in such a way that we can create a bridge between the Native Language and the JavaScript code. In this class, we select which Android view is going to be used in the React Native code. React Native for Windows + macOS brings React Native support for the Windows 10 SDK as well as the macOS 10.13 SDK. At the very beginning, we will create a new React Native application using the command: react-native init bridge_android_test_app. Name returned by the getName() method is used to reference the native view type from JavaScript. Finally, some time for JavaScript. A SimpleViewManager is convenient in this case because it applies common properties such as background color, opacity, and Flexbox layout. We’re about to build a react-native-utube-player, a Native UI component that allows playing YouTube videos in our React Native app.We’re going to achieve this by using an existing Android library, android-youtube-player, created by Pierfrancesco Soffritti.
