软件简介

react-native-keyboardevents 是 React
Native 的键盘事件。

基础示例：

// require the module
var KeyboardEvents = require('react-native-keyboardevents');

// Now get a handle on the event emitter and add your callbacks
// to the desired events.
var KeyboardEventEmitter = KeyboardEvents.Emitter;

// Each event will receive a `frames` object, which contains three keys -
// `begin`,  `end`, and `duration` . The `begin` and `end`  keys each
// contain an object describing the bounds of the keyboard (x, y, width
// and height). The `duration` key contains the length of the keyboard
// animation in seconds.
// The frame in `begin` describes the bounds of the keyboard before the
// animation occurred and the frame in `end` describes the bounds the keyboard
// will have, after the animation has completed.
KeyboardEventEmitter.on(KeyboardEvents.KeyboardWillShowEvent, (frames) => {
  console.log('will show', frames);
});
KeyboardEventEmitter.on(KeyboardEvents.KeyboardDidShowEvent, (frames) => {
  console.log('did show', frames);
});
KeyboardEventEmitter.on(KeyboardEvents.KeyboardWillHideEvent, (frames) => {
  console.log('will hide', frames);
});
KeyboardEventEmitter.on(KeyboardEvents.KeyboardDidHideEvent, (frames) => {
  console.log('did hide', frames);
});
KeyboardEventEmitter.on(KeyboardEvents.KeyboardWillChangeFrame, (frames) => {
  console.log('will change', frames);
});
KeyboardEventEmitter.on(KeyboardEvents.KeyboardDidChangeFrame, (frames) => {
  console.log('did change', frames);
});
