/**
|
|
* A foundational component for inputting text into the app via a
|
|
* keyboard. Props provide configurability for several features, such as
|
|
* auto-correction, auto-capitalization, placeholder text, and different keyboard
|
|
* types, such as a numeric keypad.
|
|
*
|
|
* The simplest use case is to plop down a `TextInput` and subscribe to the
|
|
* `onChangeText` events to read the user input. There are also other events,
|
|
* such as `onSubmitEditing` and `onFocus` that can be subscribed to. A simple
|
|
* example:
|
|
*
|
|
* ```ReactNativeWebPlayer
|
|
* import React, { Component } from 'react';
|
|
* import { AppRegistry, TextInput } from 'react-native';
|
|
*
|
|
* class UselessTextInput extends Component {
|
|
* constructor(props) {
|
|
* super(props);
|
|
* this.state = { text: 'Useless Placeholder' };
|
|
* }
|
|
*
|
|
* render() {
|
|
* return (
|
|
* <TextInput
|
|
* style={{height: 40, borderColor: 'gray', borderWidth: 1}}
|
|
* onChangeText={(text) => this.setState({text})}
|
|
* value={this.state.text}
|
|
* />
|
|
* );
|
|
* }
|
|
* }
|
|
*
|
|
* // App registration and rendering
|
|
* AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);
|
|
* ```
|
|
*
|
|
* Note that some props are only available with `multiline={true/false}`.
|
|
* Additionally, border styles that apply to only one side of the element
|
|
* (e.g., `borderBottomColor`, `borderLeftWidth`, etc.) will not be applied if
|
|
* `multiline=false`. To achieve the same effect, you can wrap your `TextInput`
|
|
* in a `View`:
|
|
*
|
|
* ```ReactNativeWebPlayer
|
|
* import React, { Component } from 'react';
|
|
* import { AppRegistry, View, TextInput } from 'react-native';
|
|
*
|
|
* class UselessTextInput extends Component {
|
|
* render() {
|
|
* return (
|
|
* <TextInput
|
|
* {...this.props} // Inherit any props passed to it; e.g., multiline, numberOfLines below
|
|
* editable = {true}
|
|
* maxLength = {40}
|
|
* />
|
|
* );
|
|
* }
|
|
* }
|
|
*
|
|
* class UselessTextInputMultiline extends Component {
|
|
* constructor(props) {
|
|
* super(props);
|
|
* this.state = {
|
|
* text: 'Useless Multiline Placeholder',
|
|
* };
|
|
* }
|
|
*
|
|
* // If you type something in the text box that is a color, the background will change to that
|
|
* // color.
|
|
* render() {
|
|
* return (
|
|
* <View style={{
|
|
* backgroundColor: this.state.text,
|
|
* borderBottomColor: '#000000',
|
|
* borderBottomWidth: 1 }}
|
|
* >
|
|
* <UselessTextInput
|
|
* multiline = {true}
|
|
* numberOfLines = {4}
|
|
* onChangeText={(text) => this.setState({text})}
|
|
* value={this.state.text}
|
|
* />
|
|
* </View>
|
|
* );
|
|
* }
|
|
* }
|
|
*
|
|
* // App registration and rendering
|
|
* AppRegistry.registerComponent(
|
|
* 'AwesomeProject',
|
|
* () => UselessTextInputMultiline
|
|
* );
|
|
* ```
|
|
*
|
|
* `TextInput` has by default a border at the bottom of its view. This border
|
|
* has its padding set by the background image provided by the system, and it
|
|
* cannot be changed. Solutions to avoid this is to either not set height
|
|
* explicitly, case in which the system will take care of displaying the border
|
|
* in the correct position, or to not display the border by setting
|
|
* `underlineColorAndroid` to transparent.
|
