Question

我想从图库中获取图像时获取图像名称。怎么做？以下是我的代码。我不知道如何继续。

            public void onClick(View v) {
                Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(i, IMAGE_PICKER_SELECT);
            }
        });
        return v;
    }

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == IMAGE_PICKER_SELECT  && resultCode == Activity.RESULT_OK) {
            bitmap = getBitmapFromCameraData(data, mainActivity);
            bitmap = getBitmapFromCameraData(data, mainActivity);
            profileImageView.setImageBitmap(bitmap);
            uploadImage();
        }
    }

    private Bitmap getBitmapFromCameraData(Intent data, Context context) {


        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };
        Cursor cursor = context.getContentResolver().query(selectedImage,filePathColumn, null, null, null);
        cursor.moveToFirst();
        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();
        return BitmapFactory.decodeFile(picturePath);



    }

以下代码可帮助您获取所选文件的图像名称：

private String getFileName(Uri selectedImage){
 File f = new File(picturePath);
 String imageName = f.getName();
 return imageName;
}

快乐编码!!!

Answer 2

您获得的ParentVC *parentVC = [self.storyboard instantiateViewControllerWithIdentifier:@"IDParentVC"]; ChildVC *childVC = [self.storyboard instantiateViewControllerWithIdentifier:@"IDChildVC"]; [childVC.view setFrame:CGRectMake(0,self.view.frame.size.height, self.view.frame.size.width, self.view.frame.size.height)]; [parentVC addChildViewController:childVC]; [parentVC.view addSubview:childVC.view]; [childVC didMoveToParentViewController:parentVC];包含图片名称从那里拿出来。例如 picturepath
