如何使用PhoneGap的显示Android手机上摄像头(how to display camera

我想通过使用Android手机上的PhoneGap捕捉图像。我尝试发布PhoneGap的页面上的代码，但相机不会出现。任何帮助是appreciated.Thank你了。

这是我的手机上显示

<!DOCTYPE html>
<html>
  <head>
    <title>Capture Photo</title>

    <script type="text/javascript" charset="utf-8" src="cordova-1.6.0.js"></script>
    <script type="text/javascript" charset="utf-8">

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

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

    // Cordova 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,
        destinationType.DATA_URL });
    }

    // 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,
        destinationType.DATA_URL });
    }

    // 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);
    }

Answer 1:

无论您capturePhoto()和capturePhotoEdit()函数需要有destinationType更新。

navigator.camera.getPicture(
    onPhotoDataSuccess,
    onFail,
    {
        quality: 50,
        destinationType.DATA_URL
    }
);

应该是这样的，

navigator.camera.getPicture(
    onPhotoDataSuccess,
    onFail,
    {
        quality: 50,
        destinationType: destinationType.DATA_URL
    }
);

Answer 2:

你添加的权限和相机功能在您AndroidMenifest文件？如果您没有添加，然后再试一次。

<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

在你的代码改变科尔多瓦版本。现在你有“科尔多瓦 - 1.6.0.js”你应该把它改为“科尔多瓦-2.5.0.js”我认为以后它会成功。像这样

<script type="text/javascript" charset="utf-8" src="cordova-2.5.0.js"></script>

Answer 4:

我一直有同样的问题，我已经得到了getPhoto（）函数现在的工作，但仍无法获得cameraPhoto（）或cameraPhotoEdit（）函数工作。我已经做了几乎一切听在这个岗位多。

哦，你可以尝试这里列出的一些解决方案：
