你好朋友......
我目前正在尝试使用Implicit Intent创建一个Dialog，我希望在其中显示我的对话框，如whatsApp（个人资料照片屏幕），在此屏幕中，whatsApp正在使用名为“删除照片”的额外字段。当我尝试制作相同类型的屏幕对话框时，我无法添加此额外字段（“删除照片”）。我已经完成了所有代码。它在Dialog中的三个选项（图库，照片，相机）工作正常，我无法在onActivityResult（）中处理这些。我发送了我的所有源代码，我已经尝试了很多，但我无法找到解决方案。 PLZ .....朋友帮助我解决这个问题。
在这段代码中我只是创建一个名为openFileChooser（）的方法，其中我已经编写了用于创建Dialog Screen的所有代码并在onActivityResult（）中处理了这些结果
这是我的代码
ProfilePhotoActivity.java

这看起来像是一个问题：
if(requestCode==FILECHOOSER_RESULTCODE)
{
if (requestCode == GALLERY_PICTURE)
除非FILECHOOSER_RESULTCODE和GALLERY_PICTURE是相同的ints，否则语句将永远不会通过。

可能可以使用请求代码来区分照片的“类型”，即
from collections import OrderedDict
doc = OrderedDict([
('cid', document['cid']),
('mac', document['mac']),
('category', document['category']),
# ... other keys ...
])
docs_uplink.append(doc)
dumped = json_util.dumps(dict(data=docs_uplink))
您可以在开始新活动之前创建Intent时使用protected static final int MY_FACE_PHOTO = 0;
protected static final int MY_CAR_PHOTO = 1;
protected static final int MY_HOUSE_PHOTO = 2;
，例如：
Intent.putExtra(String name, String value)之后，您可以在@NonNls protected static final String STRING_EXTRA = "string_extra";
@NonNls protected static final String CAMERA = "camera";
@NonNls protected static final String GALLERY = "gallery";
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI
cameraIntent.putExtra(STRING_EXTRA, CAMERA);
galleryIntent.putExtra(STRING_EXTRA, GALLERY)
startActivityForResult(takePicture,
MY_FACE_PHOTO /* put here your desired request code */)
方法中使用它们：
onActivityResult()
