调用onShowFileChooser()时如何从FileChooserParams中提取值? [英] How to extract values from FileChooserParams when onShowFileChooser() gets called?

问题描述

我们有一个混合应用程序，可在Android上运行并使用在MVC中创建的网络应用程序页面.

We have a hybrid app that runs on Android and using webapp pages created in MVC.

我们有2个按钮- 1.文档上传-单击此选项后，文件，图库"选项应该可用(无相机选项) 2.相机上传-单击此按钮应会触发手机中的相机应用.

We have 2 buttons - 1. Document upload - Files, Gallery options should be available when this is clicked (no camera option) 2. Camera upload - clicking on this should trigger camera app in phone.

我在mvc视图上有以下代码:

I have following code on mvc view :

<input type="file" id="uploadFile" name="files" accept=".pdf,.jpg,.jpeg,.gif,.png" style="display:none;" />
    <input type="file" id="capture" name="LnFImage" accept="image/*" capture="capture" style="display:none;">

在BrowserFragment.java中，我们有2个Intent:

in BrowserFragment.java, we have 2 Intents:

    Intent takePhotoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Intent chooseExistingPhotoIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

调用onShowFileChooser()时，如何根据页面上单击的按钮知道 takePhotoIntent 还是 chooseExistingPhotoIntent 来调用?

when onShowFileChooser() gets called, how do I know if takePhotoIntent to call or chooseExistingPhotoIntent to call based on the button clicked on page?

是否可以从FileChooserParams中提取值以确定哪个按钮正在调用onShowFileChooser()?

Is is possible to extract value from FileChooserParams to determine which button is calling onShowFileChooser() ?

推荐答案

可以使用FileChooserParams.getAcceptTypes()提取accept属性，有关更多详细信息，请参见

It's possible to extract accept attribute with FileChooserParams.getAcceptTypes() for more details have a look at Android documentation.

可以使用FileChooserParams.getFilenameHint() 对于capture，使用FileChooserParams.getMode() 文档中所述
