How do you create a basic button in React Native?
React native provides Button component which displays platform specific button. Following example shows how we create a platform-specific default button in React native. Platform-specific button means that the look and feel on a button will depend on whether the application is running on IOS or Android. Button component exposes two main props: title and onPress. Title props are used to display text on the button. onPress props is a callback which is invoked when the user presses the button. This is very much similar to the click event on a web browser. We can’t style the Button component provided by React native. Above example will show platform specific alert when the user presses the button. Alert is the component provided by React native framework to show platform specific modal. As I mentioned above that we can’t style Button component of React native, we can try this by changing the text colour of a button or changing the padding via style props but it won’t change the appearance of the button.
How do you create basic text input to React Native?
TextInput is provided by React native framework to implement simple text input control. Text input is one of the very basic controls of UI. Whether it is auto-complete, form, text input is a must used control in UI of application. TextInput component accepts placeholder value as props. When a user starts changing the text then the onChangeText event is triggered and when the user is done editing and hit return button, onSubmitEditing props will get invoked. TextInput component can be styled by setting style props to the component. Here is an example of the implementation of simple text input in React native: In the above example: we have a TextInput component whose value is controlled by the state. Which means our TextInput in above example is a controlled component. Once the user starts typing we update the state with an onChangeText method. Once the user submits the value, we display the value user has typed in the text box.
