问题描述

我现在工作的应用程序，启动相机和拍照，我没有用相机活动，但我写了我的相机应用程序，我想保存拍摄的图像在手机内部存储的文件夹，名为temPic

下面code生成的文件夹和图像，但是当我检查了tempPic我发现一个图像称为image1.jpg，它的大小是461115（我试图存储SD卡目录中的形象，它是相同的大小），但是当我双击了它一个黑色的形象出现，而不是采取的一项虽然在SD卡我打开它！

  FileManipulator FILEFORMAT =新FileManipulator（
                getApplicationContext（））;
        字符串路径= fileFormat.createFolder_PStrg（tempPic）+/image1.jpg;
        档案文件=新的文件（路径）;
        乌里outputFileUri = Uri.fromFile（文件）;

        的OutputStream imageFileOS;
        尝试 {


            imageFileOS = getContentResolver（）openOutputStream（outputFileUri）。
            imageFileOS.write（为arg0）;
            imageFileOS.flush（）;
            imageFileOS.close（）;
            Toast.makeText（AndroidCamera.this，
                    file.length（）+，
                    Toast.LENGTH_LONG）.show（）;
            Toast.makeText（AndroidCamera.this，
                    图片保存：+ outputFileUri.toString（）
                    Toast.LENGTH_LONG）.show（）;

        }赶上（FileNotFoundException异常E）{
            // TODO自动生成的catch块
            e.printStackTrace（）;
        }赶上（IOException异常E）{
            // TODO自动生成的catch块
            e.printStackTrace（）;
        }

        camera.start preVIEW（）;
 

解决方案

我不知道这是否可以帮助你，但我这是怎么将文件保存到SD卡和它的作品。

 公共无效saveToSD（位图outputImage）{


            文件storagePath =新的文件（Environment.getExternalStorageDirectory（）+/ MyPhotos /）;
            storagePath.mkdirs（）;

            文件MYIMAGE =新的文件（storagePath，Long.toString（System.currentTimeMillis的（））+.JPG）;

            尝试 {
                FileOutputStream中出=新的FileOutputStream（MYIMAGE）;
                outputImage.com preSS（Bitmap.Com pressFormat.JPEG，80出）;
                了out.flush（）;
                out.close（）;
            }赶上（例外五）{
                e.printStackTrace（）;
            }
        }
 

I am working now on application that start the camera and take a photo, I didn't use camera activity, but I wrote my camera app and I want to save the taken image in the internal phone storage in folder called "temPic"

The following code generate the folder and the image, but when I checked the tempPic I found an image called image1.jpg and it's size is 461115 ( I tried to store the image in SDcard directory and it is the same size), but when I double clicked it a black image appeared, not the taken one although in SDcard I opened it !!!

FileManipulator fileFormat = new FileManipulator(
                getApplicationContext());
        String path = fileFormat.createFolder_PStrg("tempPic") + "/image1.jpg";     
        File file = new File(path);
        Uri outputFileUri = Uri.fromFile(file);

        OutputStream imageFileOS;
        try {


            imageFileOS = getContentResolver().openOutputStream(outputFileUri);
            imageFileOS.write(arg0);
            imageFileOS.flush();
            imageFileOS.close();
            Toast.makeText(AndroidCamera.this, 
                    file.length()+"", 
                    Toast.LENGTH_LONG).show();
            Toast.makeText(AndroidCamera.this, 
                    "Image saved: " + outputFileUri.toString(), 
                    Toast.LENGTH_LONG).show();

        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        camera.startPreview();

解决方案

I don't know if this can help you but this is how I save a file to the SD card and it works.

        public void saveToSD(Bitmap outputImage){


            File storagePath = new File(Environment.getExternalStorageDirectory() + "/MyPhotos/"); 
            storagePath.mkdirs(); 

            File myImage = new File(storagePath, Long.toString(System.currentTimeMillis()) + ".jpg");

            try { 
                FileOutputStream out = new FileOutputStream(myImage); 
                outputImage.compress(Bitmap.CompressFormat.JPEG, 80, out); 
                out.flush();    
                out.close();
            } catch (Exception e) { 
                e.printStackTrace(); 
            }               
        }
