JavaScript + Phonegap + Android：screen.width返回糟糕（几乎随机）的值

[英]JavaScript+Phonegap+Android: screen.width returns bad (almost random) values

原文 2012-07-17 14:26:28 2 1 javascript/ android/ css/ cordova/ width

After launching app with "deviceready" event, my Phonegap app on Android returns false screen.width (window.innerWidth is the same) values on ZTE Blade (native 800px). 使用“deviceready”事件启动应用程序后，Android上的Phonegap应用程序在ZTE Blade（本机800px）上返回false screen.width（window.innerWidth相同）值。 I get width values like 320, 533 or 787 px, sometimes different values within one app instance (launch) when asking multiple times... 我得到宽度值，如320,533或787像素，有时在一个应用程序实例（启动）中有多个不同的值，当多次询问时......

I have android:screenOrientation="landscape" in my AndroidManifest.xml. 我的AndroidManifest.xml中有android：screenOrientation =“landscape”。 Using Phonegap/Cordova 1.8.1 in Eclipse (Indigo). 在Eclipse（Indigo）中使用Phonegap / Cordova 1.8.1。

Some sample values of screen.width: screen.width的一些示例值：

in index.html 在index.html中

before document.addEventListener+"deviceready": 320 在document.addEventListener +“deviceready”之前：320
just after "deviceready": 320 就在“deviceready”之后：320

then redirect three times (change window.location to different HTML file) because of 2 splash-screens and finally land to main.html. 然后重定向三次（将window.location更改为不同的HTML文件），因为2个启动屏幕，最后登陆到main.html。 I include my .js code in every file just for debugging, and get 3 console.logs: 我将.js代码包含在每个文件中仅用于调试，并获得3个console.logs：

320 320
787 787
787 787

Very strange... 很奇怪...
