在 Phonegap Android 应用程序中启用视口缩放无效 [英] Enabling viewport pinch-zoom in Phonegap Android application has no effect
问题描述
我需要能够使用我的 Android PhoneGap 应用上的视口设置打开和关闭双指缩放.
I need to be able to turn pinch-zoom on and off using the viewport setting on my Android PhoneGap app.
但是在使用 PhoneGap 时，我根本无法让视口影响捏合缩放.我无法在 PhoneGap 中打开双指缩放，但是当使用 Android Native 浏览器浏览网页时一切正常.
But I'm unable to get viewport to affect pinch-zooming at all when using PhoneGap. I cannot turn on Pinch-zoom in PhoneGap, but when browsing with the Android Native browser to the webpage everything works fine.
我花了很多时间寻找解决方案，但没有任何结果.
I have spent a lot of time searching for a solution, without any result.
我创建了一个非常简单的 index.html 用于测试，视口设置如下:
I created a very simple index.html for testing, having viewport setting like:
<meta name="viewport" content="user-scalable=yes" />
正如一些人所建议的，我也尝试过视口:
As some has suggested I have also tried the viewport:
<meta name="viewport" content="user-scalable=1" />
Android PhoneGap 的其他解决方案是启用 Android Native Pinch-Zoom，这里建议:放大android的phonegap但这对我不起作用，因为我需要能够从 javascript 控制捏缩放.IE.我需要能够使用 javascript 来更改视口设置，以控制何时可以使用捏合缩放(user-scalable=yes/user-scalable=no)
Other solutions for Android PhoneGap would be to enable Android Native Pinch-Zoom which have been suggested here: zoom in phonegap for android But this will not work for me, since I need to be able to control the pinch-zoom from javascript. I.e. I need to be able to use javascript to change the viewport setting, to control when pinch-zoom is available (user-scalable=yes / user-scalable=no)
请注意初始比例"和目标密度dpi"等其他视口设置似乎工作正常.例如设置 initial-scale=2 启动应用程序缩放.
Please observe that other viewport settings like "initial-scale" and "target-densitydpi" seems to work fine. For example setting initial-scale=2 starts the app zoomed.
(我目前正在 PhoneGap 1.4.1 和 HTC Desire HD Android 2.3.3 上测试双指缩放)
(I'm currently testing pinch-zoom on PhoneGap 1.4.1 and HTC Desire HD Android 2.3.3)
我开始觉得我漏掉了一些明显的东西，因为我发现关于类似问题的信息太少了...
I'm beginning to think I have missed something obvious, since I find so little information about similar problems...
最小的 index.html:
The minimal index.html:
<!DOCTYPE HTML>
<html>
<head>
<meta name="viewport" content="user-scalable=yes" />
<meta http-equiv="Content-type" content="text/html; charset=utf-8">
<title>Minimal AppLaud App</title>
<script type="text/javascript" charset="utf-8" src="phonegap-1.4.1.js"></script>
<script type="text/javascript" charset="utf-8">
var onDeviceReady = function() {
document.getElementById("devready").innerHTML = "OnDeviceReady fired.";
};
function init() {
document.addEventListener("deviceready", onDeviceReady, true);
}
</script>
</head>
<body onload="init();" id="stage" class="theme">
<h2>Minimal AppLaud App</h2>
<p> LOTS OF TEXT WHICH HAVE BEEN REMOVED HERE </p>
<p><span id="devready">onDeviceReady not fired.</span></p>
</body>
</html>

推荐答案
我有完全相同的问题，除了测试不同的视口设置之外，我还尝试了以下建议:使用 Phonegap 和 jQUERY Mobile 在 Android 中捏合缩放 但我无法让它工作(在三星 Galaxy 上测试)SII，安卓 4.0.3).但是，其他人报告说使用链接中的提示成功进行了缩放.希望对你也有帮助！
I have exactly the same issue and besides testing different viewport settings, I have tried the suggestions from this: Pinch Zoom in Android with Phonegap and jQUERY Mobile but I can't make it work (testing on Samsung Galaxy SII, Android 4.0.3). However, others have reported successful pinch-zooming using the tips from the link. Hope it helps you too!
