+
+events也是一个\[EventEmitter\](#EventEmitter)，可以使用EventEmitter的所有函数，这里只介绍其自身的函数。
+
+注意，events内置的触摸、按键事件必须调用loop()函数才能正常工作。例如：
+```
+events.observeKey();
+events.onKeyDown("volume_up", function(event){
+    toast("音量上键被按下了");
+});
+events.onKeyDown("menu", function(event){
+    toast("菜单键被按下了");
+});
+
+loop();
+//后面的语句不会再执行了
+```
+
+
+### events.emitter()
+
+返回一个新的EventEmitter。
+
+### events.observeKey()
+
+启用按键监听，例如音量键、Home键。
+
+在安卓4.3以上才能使用。
+
+### events.onKeyDown(keyName, listener)
+* keyName \<String\> 要监听的按键名称
+* listener \<Function\> 参数为一个[KeyEvent](#KeyEvent)
+
+注册一个按键监听函数，当有keyName对应的按键被按下会调用该函数。按键名称主要包括：
+* volume_up 音量上键
+* volume_down 音量下键
+* home 主屏幕键
+* back 返回键
+* menu 菜单键
+
+### events.onKeyUp(keyName,  listener)
+* keyName \<String\> 要监听的按键名称
+* listener \<Function\> 参数为一个[KeyEvent](#KeyEvent)
+
+
+注册一个按键监听函数，当有keyName对应的按键弹起时会调用该函数。
+
+### events.onceKeyDown(keyName, listener)
+* keyName \<String\> 要监听的按键名称
+* listener \<Function\> 参数为一个[KeyEvent](#KeyEvent)
+
+注册一个按键监听函数，当有keyName对应的按键被按下时会调用该函数，之后会注销该按键监听。也就是listener只会被调用一次。
+
+### events.onceKeyUp(keyName, listener)
+* keyName \<String\> 要监听的按键名称
+* listener \<Function\> 参数为一个[KeyEvent](#KeyEvent)
+
+注册一个按键监听函数，当有keyName对应的按键弹起时会调用该函数，之后会注销该按键监听。也就是listener只会被调用一次。
+
+### events.removeAllKeyDownListeners(keyName)
+* keyName \<String\> 按键名称
+
+删除该按键的KeyDown事件的所有监听。
+
+### events.removeAllKeyUpListeners(keyName)
+* keyName \<String\> 按键名称
+
+删除该按键的KeyUp事件的所有监听。
+
+### events.observeTouch()
+
+启用屏幕触摸监听。（需要root权限）
+
+### events.setTouchEventTimeout(timeout)
+* timeout \<Number\> 两个触摸事件的最小间隔。单位毫秒。默认为10毫秒。
+
+设置两个触摸事件分发的最小时间间隔。
+
+例如间隔为10毫秒的话，前一个触摸事件发生并被注册的监听器处理后，至少要过10毫秒才能分发和处理下一个触摸事件，这10毫秒之间的触摸将会被忽略。
+
+### events.getTouchEventTimeout()
+
+返回触摸事件的最小时间间隔。
+
+### events.onTouch(listener)
+* listener \<Function\> 参数为Point的函数
+
+注册一个触摸监听函数。
+
+例如:
+```
+events.observeTouch();
+events.onTouch(function(p){
+    log(p.x + ", " + p.y);
+});
+events.loop();
+```
+
+### events.removeAllTouchListeners()
+
+删除所有事件监听函数。
+
+### key事件
+
+当有按键被按下或弹起时会触发该事件。
+```
+"auto";
+events.observeKey();
+events.on("key", function(keyCode, event){
+    //处理按键事件
+});
+events.loop();
+```
+其中监听器的参数KeyCode包括：
+* KeyEvent.KEYCODE_HOME 主页键
+* KeyEvent.KEYCODE_BACK 返回键
+* KeyEvent.KEYCODE_MENU 菜单键
+* KeyEvent.KEYCODE_VOLUME_UP 音量上键
+* KeyEvent.KEYCODE_VOLUME_DOWN 音量下键
+
+### key_down事件
+
+当有按键被按下时会触发该事件。
+```
+"auto";
+events.observeKey();
+events.on("key_down", function(keyCode, event){
+    //处理按键按下事件
+});
+events.loop();
+```
+
+### key_up事件
+
+当有按键弹起时会触发该事件。
+```
+"auto";
+events.observeKey();
+events.on("key_up", function(keyCode, event){
+    //处理按键弹起事件
+});
+events.loop();
+```
+
+
+# EventEmitter
+
+### EventEmitter.defaultMaxListeners
+
+每个事件默认可以注册最多 10 个监听器。 单个 EventEmitter 实例的限制可以使用 emitter.setMaxListeners(n) 方法改变。 所有 EventEmitter 实例的默认值可以使用 EventEmitter.defaultMaxListeners 属性改变。 
+
+设置 EventEmitter.defaultMaxListeners 要谨慎，因为会影响所有 EventEmitter 实例，包括之前创建的。 因而，调用 emitter.setMaxListeners(n) 优先于 EventEmitter.defaultMaxListeners。
+
+注意，与NodeJs不同，**这是一个硬性限制**。 EventEmitter 实例不允许添加更多的监听器，监听器超过最大数量时会抛出TooManyListenersException。
+```
+emitter.setMaxListeners(emitter.getMaxListeners() + 1);
+emitter.once('event', () => {
+  // 做些操作
+  emitter.setMaxListeners(Math.max(emitter.getMaxListeners() - 1, 0));
+});
+```
+## EventEmitter.addListener(eventName, listener)
+* eventName \<any\>
+* listener \<Function\>
+emitter.on(eventName, listener) 的别名。
+
+### EventEmitter.emit(eventName\[, ...args\])
+* eventName <any>
+* args <any>
+
+按监听器的注册顺序，同步地调用每个注册到名为 eventName 事件的监听器，并传入提供的参数。
+
+如果事件有监听器，则返回 true ，否则返回 false。
+
+### EventEmitter.eventNames()
+
+返回一个列出触发器已注册监听器的事件的数组。 数组中的值为字符串或符号。
+```
+const myEE = events.emitter();
+myEE.on('foo', () => {});
+myEE.on('bar', () => {});
+
+const sym = Symbol('symbol');
+myEE.on(sym, () => {});
+
+console.log(myEE.eventNames());
+// 打印: [ 'foo', 'bar', Symbol(symbol) ]
+```
+### EventEmitter.getMaxListeners()#
+
+返回 EventEmitter 当前的最大监听器限制值，该值可以通过 emitter.setMaxListeners(n) 设置或默认为 EventEmitter.defaultMaxListeners。
+
+### EventEmitter.listenerCount(eventName)
+* eventName <any> 正在被监听的事件名
+
+返回正在监听名为 eventName 的事件的监听器的数量。
+
+### EventEmitter.listeners(eventName)
+* eventName <any>
+
+返回名为 eventName 的事件的监听器数组的副本。
+```
+server.on('connection', (stream) => {
+  console.log('someone connected!');
+});
+console.log(util.inspect(server.listeners('connection')));
+// 打印: [ [Function] ]
+```
+
+### EventEmitter.on(eventName, listener)
+* eventName <any> 事件名
+* listener <Function> 回调函数
+
+添加 listener 函数到名为 eventName 的事件的监听器数组的末尾。 不会检查 listener 是否已被添加。 多次调用并传入相同的 eventName 和 listener 会导致 listener 被添加与调用多次。
+```
+server.on('connection', (stream) => {
+  console.log('有连接！');
+});
+```
+返回一个 EventEmitter 引用，可以链式调用。
+
+默认情况下，事件监听器会按照添加的顺序依次调用。 emitter.prependListener() 方法可用于将事件监听器添加到监听器数组的开头。
+```
+const myEE = events.emitter();
+myEE.on('foo', () => console.log('a'));
+myEE.prependListener('foo', () => console.log('b'));
+myEE.emit('foo');
+// 打印:
+//   b
+//   a
+```
+
+
+### EventEmitter.once(eventName, listener)#
+* eventName <any> 事件名
+* listener <Function> 回调函数
+
+添加一个单次 listener 函数到名为 eventName 的事件。 下次触发 eventName 事件时，监听器会被移除，然后调用。
+```
+server.once('connection', (stream) => {
+  console.log('首次调用！');
+});
+```
+返回一个 EventEmitter 引用，可以链式调用。
+
+默认情况下，事件监听器会按照添加的顺序依次调用。 emitter.prependOnceListener() 方法可用于将事件监听器添加到监听器数组的开头。
+```
+const myEE = events.emitter();
+myEE.once('foo', () => console.log('a'));
+myEE.prependOnceListener('foo', () => console.log('b'));
+myEE.emit('foo');
+// 打印:
+//   b
+//   a
+```
+
+### EventEmitter.prependListener(eventName, listener)
+* eventName <any> 事件名
+* listener <Function> 回调函数
+
+添加 listener 函数到名为 eventName 的事件的监听器数组的开头。 不会检查 listener 是否已被添加。 多次调用并传入相同的 eventName 和 listener 会导致 listener 被添加与调用多次。
+```
+server.prependListener('connection', (stream) => {
+  console.log('有连接！');
+});
+```
+返回一个 EventEmitter 引用，可以链式调用。
+
+### EventEmitter.prependOnceListener(eventName, listener)
+* eventName <any> 事件名
+* listener <Function> 回调函数
+
+添加一个单次 listener 函数到名为 eventName 的事件的监听器数组的开头。 下次触发 eventName 事件时，监听器会被移除，然后调用。
+```
+server.prependOnceListener('connection', (stream) => {
+  console.log('首次调用！');
+});
+```
+返回一个 EventEmitter 引用，可以链式调用。
+
+### EventEmitter.removeAllListeners(\[eventName\])
+* eventName <any>
+
+移除全部或指定 eventName 的监听器。
+
+注意，在代码中移除其他地方添加的监听器是一个不好的做法，尤其是当 EventEmitter 实例是其他组件或模块创建的。
+
+返回一个 EventEmitter 引用，可以链式调用。
+
+### EventEmitter.removeListener(eventName, listener)
+* eventName <any>
+* listener <Function>
+
+从名为 eventName 的事件的监听器数组中移除指定的 listener。
+```
+const callback = (stream) => {
+  console.log('有连接！');
+};
+server.on('connection', callback);
+// ...
+server.removeListener('connection', callback);
+```
+removeListener 最多只会从监听器数组里移除一个监听器实例。 如果任何单一的监听器被多次添加到指定 eventName 的监听器数组中，则必须多次调用 removeListener 才能移除每个实例。
+
+
+注意，一旦一个事件被触发，所有绑定到它的监听器都会按顺序依次触发。 这意味着，在事件触发后、最后一个监听器完成执行前，任何 removeListener() 或 removeAllListeners() 调用都不会从 emit() 中移除它们。 随后的事件会像预期的那样发生。
+```
+const myEmitter = events.emitter();
+
+const callbackA = () => {
+  console.log('A');
+  myEmitter.removeListener('event', callbackB);
+};
+
+const callbackB = () => {
+  console.log('B');
+};
+
+myEmitter.on('event', callbackA);
+
+myEmitter.on('event', callbackB);
+
+// callbackA 移除了监听器 callbackB，但它依然会被调用。
+// 触发是内部的监听器数组为 [callbackA, callbackB]
+myEmitter.emit('event');
+// 打印:
+//   A
+//   B
+
+// callbackB 被移除了。
+// 内部监听器数组为 [callbackA]
+myEmitter.emit('event');
+// 打印:
+//   A
+```
+因为监听器是使用内部数组进行管理的，所以调用它会改变在监听器被移除后注册的任何监听器的位置索引。 虽然这不会影响监听器的调用顺序，但意味着由 emitter.listeners() 方法返回的监听器数组副本需要被重新创建。
+
+返回一个 EventEmitter 引用，可以链式调用。
+
+### EventEmitter.setMaxListeners(n)
+* n <integer>
+
+默认情况下，如果为特定事件添加了超过 10 个监听器，则 EventEmitter 会打印一个警告。 此限制有助于寻找内存泄露。 但是，并不是所有的事件都要被限为 10 个。 emitter.setMaxListeners() 方法允许修改指定的 EventEmitter 实例的限制。 值设为 Infinity（或 0）表明不限制监听器的数量。
+
+返回一个 EventEmitter 引用，可以链式调用。
+
+# KeyEvent
+
+### KeyEvent.getAction()
+
+返回事件的动作。包括：
+* KeyEvent.ACTION_DOWN 按下事件
+* KeyEvent.ACTION_UP 弹起事件
+
+### KeyEvent.getKeyCode()
+
+返回按键的键值。包括：
+* KeyEvent.KEYCODE_HOME 主页键
+* KeyEvent.KEYCODE_BACK 返回键
+* KeyEvent.KEYCODE_MENU 菜单键
+* KeyEvent.KEYCODE_VOLUME_UP 音量上键
+* KeyEvent.KEYCODE_VOLUME_DOWN 音量下键
+
+### KeyEvent.getEventTime()
+
+返回事件发生的时间戳。
+
+### KeyEvent.getDownTime()
+
+返回最近一次按下事件的时间戳。如果本身是按下事件，则与getEventTime()相同。
+
+### KeyEvent.keyCodeToString(keyCode)
+
+把键值转换为字符串。例如KEYCODE_HOME转换为"KEYCODE_HOME"。

+timer 模块暴露了一个全局的 API，用于在某个未来时间段调用调度函数。 因为定时器函数是全局的，所以使用该 API 无需调用 timer.***
+
+Auto.js 中的计时器函数实现了与 Web 浏览器提供的定时器类似的 API，除了它使用了一个不同的内部实现，它是基于 Android Looper-Handler机制构建的。其实现机制与Node.js比较相似。
+
+不同于Web浏览器和Node.js，在Auto.js中，必须显式地调用loop()函数开始Looper循环才能使所有计时器开始工作。loop()函数是一个"死循环", 在他之后的语句将不会被执行。
+
+### loop()
+
+开始Looper循环。使所有定时器工作所必须。
+注意，何时调用loop不会影响setTimeout等函数的计时，例如：
+```
+setTimout(function(){
+    toast("hello");
+    exit();
+}, 2000);
+sleep(1000);
+loop();
+```
+这段代码将在运行后大约2秒显示"hello"。
+
+### setImmediate(callback\[, ...args\])
+* callback \<Function\> 在 Auto.js 循环的当前回合结束时要调用的函数。
+* ...args \<any\> 当调用 callback 时要传入的可选参数。
+
+预定立即执行的 callback，它是在 I/O 事件的回调之后被触发。 返回一个用于 clearImmediate() 的 id。
+
+当多次调用 setImmediate() 时，callback 函数会按照它们被创建的顺序依次执行。 每次事件循环迭代都会处理整个回调队列。 如果一个立即定时器是被一个正在执行的回调排入队列的，则该定时器直到下一次事件循环迭代才会被触发。
+
+### setInterval(callback, delay\[, ...args\])
+* callback \<Function\> 当定时器到点时要调用的函数。
+* delay \<number\> 调用 callback 之前要等待的毫秒数。
+* ...args \<any\> 当调用 callback 时要传入的可选参数。
+
+预定每隔 delay 毫秒重复执行的 callback。 返回一个用于 clearInterval() 的 id。
+
+当 delay 小于 0 时，delay 会被设为 0。
+
+### setTimeout(callback, delay\[, ...args\])
+* callback \<Function\> 当定时器到点时要调用的函数。
+* delay \<number\> 调用 callback 之前要等待的毫秒数。
+* ...args \<any\> 当调用 callback 时要传入的可选参数。
+
+预定在 delay 毫秒之后执行的单次 callback。 返回一个用于 clearTimeout() 的 id。
+
+callback 可能不会精确地在 delay 毫秒被调用。 Auto.js 不能保证回调被触发的确切时间，也不能保证它们的顺序。 回调会在尽可能接近所指定的时间上调用。
+
+当 delay 小于 0 时，delay 会被设为 0。
+
+setImmediate()、setInterval() 和 setTimeout() 方法每次都会返回表示预定的计时器的id。 它们可用于取消定时器并防止触发。
+
+
+### clearImmediate(id)#
+* id \<Number\> 一个 setImmediate() 返回的 id。
+
+取消一个由 setImmediate() 创建的 Immediate 对象。
+
+### clearInterval(id)#
+* id \<Number\> 一个 setInterval() 返回的 id。
+
+取消一个由 setInterval() 创建的 Timeout 对象。
+
+### clearTimeout(id)
+* id \<Number\> 一个 setTimeout() 返回的 id。
+
+取消一个由 setTimeout() 创建的 Timeout 对象。
