【问题描述】：

我正在开发一个 android 应用程序，它有一个个人资料片段，用户可以通过拍照或从图库中选择上传个人资料图片。目前，通过 Activity.RESULT_OK 一切正常。但问题是 onActivityResult data.getData() 什么都不返回。我对这个问题进行了研究，但无济于事。

这是我的 editprofile 片段中包含的两个方法。

private void setGalleryBtn() 
    if (PermissionHandler.checkPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)) 
        AppHelper.LogCat("Read data permission already granted.");
        new PickerBuilder(getActivity(), PickerBuilder.SELECT_FROM_GALLERY)
                .setOnImageReceivedListener(imageUri -> 
                    Intent data = new Intent();
                    data.setData(imageUri);
                    AppHelper.LogCat("new image SELECT_FROM_GALLERY" + imageUri);
                    mEditProfilePresenter.onActivityResult(this, AppConst.SELECT_PROFILE_PICTURE, RESULT_OK, data);

                )
                .setImageName(getActivity().getString(R.string.app_name))
                .setImageFolderName(getActivity().getString(R.string.app_name))
                .setCropScreenColor(R.color.colorPrimary)
                .withTimeStamp(false)
                .setOnPermissionRefusedListener(() -> 
                    PermissionHandler.requestPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE);
                )
                .start();

     else 
        AppHelper.LogCat("Please request Read data permission.");
        PermissionHandler.requestPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE);
    





private void setCameraBtn() 
    if (PermissionHandler.checkPermission(getActivity(), Manifest.permission.CAMERA)) 
        AppHelper.LogCat("camera permission already granted.");
        new PickerBuilder(getActivity(), PickerBuilder.SELECT_FROM_CAMERA)
                .setOnImageReceivedListener(imageUri -> 

                    AppHelper.LogCat("new image SELECT_FROM_CAMERA " + imageUri);
                    Intent data = new Intent();
                    data.setData(imageUri);
                    mEditProfilePresenter.onActivityResult(this, AppConst.SELECT_PROFILE_CAMERA, RESULT_OK, data);

                )
                .setImageName(getActivity().getString(R.string.app_name))
                .setImageFolderName(getActivity().getString(R.string.app_name))
                .setCropScreenColor(R.color.colorPrimary)
                .withTimeStamp(false)
                .setOnPermissionRefusedListener(() -> 
                    PermissionHandler.requestPermission(getActivity(), Manifest.permission.CAMERA);
                )
                .start();
     else 
        AppHelper.LogCat("Please request camera  permission.");
        PermissionHandler.requestPermission(getActivity(), Manifest.permission.CAMERA);
    

这是我的 EditProfilePresenter.onActivityResult 方法。

public void onActivityResult(Edit_profile_fragment myEdit_profile_fragment, int requestCode, int resultCode, Intent data) 
    String imagePath = null;
    if (resultCode == Activity.RESULT_OK) 
        if (PermissionHandler.checkPermission(myEdit_profile_fragment.getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE)) 
            AppHelper.LogCat("Read contact data permission already granted.");

            switch (requestCode) 
                case AppConst.SELECT_PROFILE_PICTURE:
                        imagePath = FilesManager.getPath(myEdit_profile_fragment.getActivity(), data.getData());
                    break;
                case AppConst.SELECT_PROFILE_CAMERA:
                    if (data.getData() != null) 
                        imagePath = FilesManager.getPath(myEdit_profile_fragment.getActivity(), data.getData());

                     else 
                        try 
                            String[] projection = new String[]MediaStore.Images.ImageColumns._ID, MediaStore.Images.ImageColumns.DATA, MediaStore
                                    .Images.ImageColumns.BUCKET_DISPLAY_NAME, MediaStore.Images.ImageColumns.DATE_TAKEN, MediaStore.Images
                                    .ImageColumns.MIME_TYPE;
                            final Cursor cursor = myEdit_profile_fragment.getActivity().getContentResolver()
                                    .query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null, null, MediaStore.Images.ImageColumns
                                            .DATE_TAKEN + " DESC");

                            if (cursor != null && cursor.moveToFirst()) 
                                String imageLocation = cursor.getString(1);
                                cursor.close();
                                File imageFile = new File(imageLocation);
                                if (imageFile.exists()) 
                                    imagePath = imageFile.getPath();
                                
                            
                         catch (Exception e) 
                            AppHelper.LogCat("error" + e);
                        
                    
                    break;
            


            if (imagePath != null) 
                EventBus.getDefault().post(new Pusher(AppConst.EVENT_BUS_IMAGE_PROFILE_PATH, imagePath));
             else 
                AppHelper.LogCat("imagePath is null");
            
         else 
            AppHelper.LogCat("Please request Read contact data permission.");
            PermissionHandler.requestPermission(myEdit_profile_fragment.getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE);
        
    

请问我哪里错了？

【问题讨论】：

您找到解决方案了吗？

【参考方案1】：

你可以试试这个

if (requestCode == REQUEST_FROM_CAMERA && resultCode == RESULT_OK)

Bundle extras2 = data.getExtras();
 if (extras2 != null) 
                    // do your stuff here
                      
                   else 
                  // handle this case as well if data.getExtras() is null
                    Uri selectedImage = data.getData();
