Using the Button Component

Importing Button

Before using the Button component from react-native-paper, it must be imported into the project. The following code should be added to the top of the file:

import { Button } from 'react-native-paper';

Basic Usage

The Button component can be used to create a variety of buttons with different styles and functionality. The basic usage of the Button component is as follows:

<Button mode="contained" onPress={() => console.log('Pressed')}>
  Press me
</Button>

This will create a button with the label “Press me” that will log a message to the console when pressed. The mode prop specifies the style of the button and can be set to "contained", "outlined", or "text". The onPress prop specifies the function to be executed when the button is pressed.

Handling Press Events

const handlePress = () => {
  console.log('Button pressed');
};

<Button mode="contained" onPress={handlePress}>
  Press me
</Button>

This will create a button with the label “Press me” that will log the message “Button pressed” to the console when pressed.

In addition to onPress, the Button component also supports the following props for handling press events:

• onLongPress: function to be executed when the button is long-pressed
• onPressIn: function to be executed when the button is pressed down
• onPressOut: function to be executed when the button is released

Overall, the Button component from react-native-paper is a versatile and easy-to-use component for creating buttons in React Native applications.

Styling the Button

React Native Paper Button component provides several ways to style buttons to match the design of the app. This section will discuss two ways to style the button: Custom Styles and Themes and Theming.

Custom Styles

The Button component provides several props to customize the style of the button. The following table lists some of the most commonly used props:

Prop	Description
mode	Sets the mode of the button. Available options are text, outlined, and contained.
color	Sets the background color of the button.
labelStyle	Styles the text of the button label.
style	Styles the container of the button.
contentStyle	Styles the content container of the button.

For example, to create a button with a red background color and white text:

<Button mode="contained" color="red" labelStyle={{color: "white"}}>Press Me</Button>

Themes and Theming

React Native Paper provides a theming system that allows developers to create a consistent look and feel across the app. The theme consists of a set of colors, fonts, and other properties that can be customized.

To use the theming system, the app must first create a theme object and wrap the app with the Provider component. The following code shows an example of creating a theme object:

import { DefaultTheme, Provider as PaperProvider } from 'react-native-paper';

const theme = {
  ...DefaultTheme,
  colors: {
    ...DefaultTheme.colors,
    primary: 'blue',
    accent: 'yellow',
  },
};

Once the theme object is created, wrap the app with the PaperProvider component and pass the theme object as a prop:

<PaperProvider theme={theme}>
  <App />
</PaperProvider>

After wrapping the app with the PaperProvider component, all the components in the app will use the theme. To customize the style of the Button component, modify the theme object.

For example, to change the primary color of the Button component:

const theme = {
  ...DefaultTheme,
  colors: {
    ...DefaultTheme.colors,
    primary: 'red',
  },
};

In conclusion, the Button component in React Native Paper provides several ways to style the button to match the design of the app. Developers can use the provided props to customize the style of the button or use the theming system to create a consistent look and feel across the app.

Button Variants

React Native Paper provides three types of buttons: Contained Button, Outlined Button, and Text Button.

Contained Button

Contained buttons are filled with color and have a shadow to make them stand out. They are the default button type and are used for primary actions. They are visually prominent and attract users’ attention.

Contained buttons can be customized by changing their color, size, and shape. They can also be disabled or made to show a loading indicator.

Text buttons are the least visually prominent of the three button types. They are used for tertiary actions and are often used in conjunction with other button types.

Text buttons can be customized by changing their color and size. They can also be disabled or made to show a loading indicator.
