Android应用拍照后恢复到索引页 [英] Android app reverts back to index page after taking a picture

问题描述

所以我有这个程序，我建设，我是一个新手到Android应用。我使用PhoneGap的帮助使事情变得更容易。我用自己的例子，他们已经发布并拍摄照片时，应用程序恢复到我的应用程序的索引页，而不是去我想要的页面。

我想知道的是我在哪里可以修改code到另一个页面，并显示该图片只是我坐？

下面是我的一些code的：

 ＆LT;脚本SRC =PhoneGap的-1.1.0.js类型=文/ JavaScript的＆GT;＆LT; / SCRIPT＆GT;
＆LT; /头＆GT;
＆LT;脚本类型=文/ JavaScript的字符集=utf-8＆GT;    VAR pictureSource; //图片来源
    VAR destinationType; //设置返回值的格式    //等待PhoneGap的与设备连接
    //
    document.addEventListener（deviceready，onDeviceReady，FALSE）;    // PhoneGap的是随时可以使用！
    //
    功能onDeviceReady（）{
        pictureSource = navigator.camera.PictureSourceType;
        destinationType = navigator.camera.DestinationType;
    }    //如果照片是成功检索调用
    //
    功能onPhotoDataSuccess（为imageData）{
      //取消注释查看的base64 EN codeD图像数据
      //执行console.log（为imageData）;      //获取图像句柄
      //
      变种smallImage =的document.getElementById（'smallImage'）;      //取消隐藏图像元素
      //
      smallImage.style.display =块;      //显示所拍摄的照片
      //内联CSS规则是用来调整图像大小
      //
      smallImage.src =数据：图像/ JPEG; BASE64，+为imageData;
    }    //如果照片是成功检索调用
    //
    功能onPhotoURISuccess（imageURI）{
      //取消注释查看图像文件URI
      //执行console.log（imageURI）;      //获取图像句柄
      //
      变种largeImage =的document.getElementById（'largeImage'）;      //取消隐藏图像元素
      //
      largeImage.style.display =块;      //显示所拍摄的照片
      //内联CSS规则是用来调整图像大小
      //
      largeImage.src = imageURI;
    }    //一个按钮将调用这个函数
    //
    功能capturePhoto（）{
      //将图片使用设备的摄像头和图像检索为base64-CN codeD字符串
      navigator.camera.getPicture（onPhotoDataSuccess，onFail，{质量：50}）;
    }    //一个按钮将调用这个函数
    //
    功能capturePhotoEdit（）{
      //将图片使用设备的摄像头，让编辑和图像检索为base64-CN codeD字符串
      navigator.camera.getPicture（onPhotoDataSuccess，onFail，{质量：20，allowEdit：真}）;
    }    //一个按钮将调用这个函数
    //
    功能getPhoto（源）{
      //从指定源中检索图像文件位置
      navigator.camera.getPicture（onPhotoURISuccess，onFail，{质量：50，
        destinationType：destinationType.FILE_URI，
        sourceType的：源}）;
    }    //调用如果有什么不好的事情发生。
    //
    功能onFail（消息）{
      警报（'因为失败：'+消息）;
    }    ＆LT; / SCRIPT＆GT;

解决方案

不是你code。

该错误是由写得不好的相机应用程序引起的。

试着安装一个不同的相机应用 - 我用相机去360

So i have this app i'm building and i'm a newbie to android apps. I am using phonegap to assist in making things easier. i used their example they have posted and when take the picture the app reverts back to the index page of my app instead of going to the page i want.

what i would like to know is where do i modify the code to go to another page and display the picture i just took?

here is some of my code:

    <script src="phonegap-1.1.0.js" type="text/javascript"></script>
</head>
<script type="text/javascript" charset="utf-8">

    var pictureSource;   // picture source
    var destinationType; // sets the format of returned value 

    // Wait for PhoneGap to connect with the device
    //
    document.addEventListener("deviceready",onDeviceReady,false);

    // PhoneGap is ready to be used!
    //
    function onDeviceReady() {
        pictureSource=navigator.camera.PictureSourceType;
        destinationType=navigator.camera.DestinationType;
    }

    // Called when a photo is successfully retrieved
    //
    function onPhotoDataSuccess(imageData) {
      // Uncomment to view the base64 encoded image data
      // console.log(imageData);

      // Get image handle
      //
      var smallImage = document.getElementById('smallImage');

      // Unhide image elements
      //
      smallImage.style.display = 'block';

      // Show the captured photo
      // The inline CSS rules are used to resize the image
      //
      smallImage.src = "data:image/jpeg;base64," + imageData;
    }

    // Called when a photo is successfully retrieved
    //
    function onPhotoURISuccess(imageURI) {
      // Uncomment to view the image file URI 
      // console.log(imageURI);

      // Get image handle
      //
      var largeImage = document.getElementById('largeImage');

      // Unhide image elements
      //
      largeImage.style.display = 'block';

      // Show the captured photo
      // The inline CSS rules are used to resize the image
      //
      largeImage.src = imageURI;
    }

    // A button will call this function
    //
    function capturePhoto() {
      // Take picture using device camera and retrieve image as base64-encoded string
      navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 50 });
    }

    // A button will call this function
    //
    function capturePhotoEdit() {
      // Take picture using device camera, allow edit, and retrieve image as base64-encoded string  
      navigator.camera.getPicture(onPhotoDataSuccess, onFail, { quality: 20, allowEdit: true }); 
    }

    // A button will call this function
    //
    function getPhoto(source) {
      // Retrieve image file location from specified source
      navigator.camera.getPicture(onPhotoURISuccess, onFail, { quality: 50, 
        destinationType: destinationType.FILE_URI,
        sourceType: source });
    }

    // Called if something bad happens.
    // 
    function onFail(message) {
      alert('Failed because: ' + message);
    }

    </script>
<body>




<div data-role="page" id="option" data-theme="e">
<div data-role="header" data-theme="e">
<h2 class="longHeader ui-title">Wedding Registry Scanner</h2>
</div>
<div data-role="controlgroup">
<div data-role="content" data-theme="d">

<a href="#" onclick="capturePhoto();" data-role="button"><img src="images/camera.png"></a>
<a href="manage.html" data-role="button"><img src="images/list.png"></a>

</div>
</div>

</div>
<div data-role="footer" data-theme="e">
        <h4 class="smallFont">Prejean IT Solutions 2011&copy;</h4>
</div>


<div data-role="page" id="capture" data-theme="e">
<div data-role="header" data-theme="e">
<h2 class="longHeader ui-title">Capture Photo</h2></div>
<div data-role="content" data-theme="d">
<img style="display:none;width:60px;height:60px;" id="smallImage" src="" />
    <img style="display:none;" id="largeImage" src="" />
</div>
</div>

EDIT: this is in my android manifest file.

<activity android:name="reg.scanner.DroidGap" 
        android:label="@string/app_name" 
        android:configChanges="orientation|keyboardHidden"> 
        <intent-filter> </intent-filter> 
        </activity>

解决方案

Its not your code.

The error is caused by poorly written Camera application.

Try installing a different Camera App - I use Go Camera 360
