问题描述

由于 Cordova 3.4.0 和 JQuery Mobile 1.4.2，我正在尝试在我的应用程序中检测 showkeyboard 和 hidekeyboard 事件.在配置文件中，全屏属性设置为true(我需要).

I'm trying to detect the showkeyboard and hidekeyboard events in my application running thanks to Cordova 3.4.0 and JQuery Mobile 1.4.2. In the configuration file, the fullscreen attribute is set to true (I need it).

事实是，在 LogCat 中，我无法阅读(显然是由于全屏模式):

The fact is, in LogCat, I can't read (apprently it's due to the fullscreen mode) :

SoftKeyboardDetect : 忽略此事件

SoftKeyboardDetect : Ignore this event

是否有任何解决方案来检测这两个事件?我通过检测输入字段上的模糊和焦点事件尝试了另一种方法.它可以工作，但是当键盘被后退按钮关闭时，这些事件不会被调用.

Is there any solution to detect these two events? I tried an alternative way by detecting blur and focus events on my input field. It works, but when the keyboard is closed by the back button, those events are not called.

所以，我尝试检测后退按钮事件，但它不起作用(http://simonmacdonald.blogspot.fr/2011/05/overriding-back-button-in-phonegap.html).

So, I tried to detect the backbutton event, but it doesn't work (http://simonmacdonald.blogspot.fr/2011/05/overriding-back-button-in-phonegap.html).

推荐答案

我认为这将满足您的需求 -

I think this will work for your needs -

document.addEventListener('deviceready', onDeviceReady, false);

function onDeviceReady () {
    document.addEventListener('hidekeyboard', onKeyboardHide, false);
    document.addEventListener('showkeyboard', onKeyboardShow, false);
}

function onKeyboardHide() {
    console.log('onKeyboardHide');
}

function onKeyboardShow() {
    console.log('onKeyboardShow');
}

//编辑

由于您无法挂钩这些事件，因此您需要一个插件.这个可以解决问题.

Since you cannot hook into those events you need a plugin. This one here will do the trick.

要安装插件执行 cordova 插件添加 com.ionic.keyboard

// This event fires when the keyboard will be shown

window.addEventListener('native.keyboardshow', keyboardShowHandler);

function keyboardShowHandler(e){
    console.log('Keyboard height is: ' + e.keyboardHeight);
}

// This event fires when the keyboard will hide

window.addEventListener('native.keyboardhide', keyboardHideHandler);

function keyboardHideHandler(e){
    console.log('Goodnight, sweet prince');
}
