在自定义文件夹的Andr​​oid保存相机图像 [英] Android Save Camera Image in Custom Folder

问题描述

我知道这个问题似乎重复比对这里一些其他问题<一href=\"http://stackoverflow.com/questions/8402378/how-to-save-image-captured-with-camera-in-specific-folder\">How保存在特定的文件夹 [像这样]用相机拍摄的图像，但我仍然有麻烦。我想要做的是使一个应用程序，你拍照与摄像头后，图像将被保存到一个新的文件夹（应用程序名称后标题）。我看到该文件夹​​的创建，但图像似乎没有被插入到他们。下面是我的一些code，我相信我搞砸了的。任何帮助那里将是一个很大的帮助。谢谢！

  camera.setOnClickListener（新View.OnClickListener（）{
            公共无效的onClick（视图v）{
                // TODO自动生成方法存根
                I =新意图（android.provider.MediaStore.ACTION_IM​​AGE_CAPTURE）;
                startActivityForResult（ⅰ，cameraData）;
            }
        }）;
    }    私人无效的SaveToFile（字符串消息）抛出异常{
        字符串文件路径= getFilesDir（）+;
        档案文件=新的文件（文件路径+/ SD卡/ DCIM / 100MEDIA / Wardobe）;
        FileOutputStream中出=新的FileOutputStream（文件，真正的）;
        out.write（message.getBytes（））;
        out.close（）;
        saveImage（文件路径，/sdcard/DCIM/100MEDIA/Wardobe/image.jpg，BMP）;
        如果（battleborn！= NULL）{
            saveImage（文件路径，SD卡/ DCIM / 100MEDIA /衣柜/ image.jpg文件，BMP）;
        }    }
    公共无效saveImage（字符串路径，字符串目录，位图图像）{
        尝试{
            FOS的FileOutputStream =新的FileOutputStream（路径+方向）;
            的BufferedOutputStream流=新的BufferedOutputStream（FOS）;
            bmp.com preSS（比较pressFormat.JPEG，50，流）;
            stream.flush（）;
            stream.close（）;
        }
        赶上（FileNotFoundException异常五）{
            e.printStackTrace（）;
        }
        赶上（IOException异常五）{
            e.printStackTrace（）;
        }
    }
 

解决方案

尝试使用这种

 文件f =新的文件（Environment.getExternalStorageDirectory（）
            档案文件=新的文件（环境
                    .getExternalStorageDirectory（）
                    +文件分割符
                    +/ your_folder_name /+.PNG）;            FOS的FileOutputStream = NULL;
            尝试{
                FOS =新的FileOutputStream（文件）;
                如果（FOS！= NULL）{
                    bitmap.com preSS（Bitmap.Com pressFormat.PNG，90，FOS）;
                    fos.close（）;
                }
            }
 

不要忘了允许添加到您的mainfest文件。

I know this question may seem repetitive as compared to a few other questions on here How to save image captured with camera in specific folder[like this] but I am still having trouble. What I'm trying to do is make an app that after you take a picture with the camera, the image will be saved into a new folder (titled after the app name). I am seeing that the folder was created, but the images don't seem to be inserting into them. The following is some of my code where I believe I'm screwing up. Any help out there would be a big help. Thank you!

  camera.setOnClickListener(new View.OnClickListener() {                
            public void onClick(View v) {
                // TODO Auto-generated method stub
                i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(i, cameraData); 
            }
        });


    } 

    private void saveToFile(String message) throws Exception {
        String filePath = getFilesDir()+"";
        File file = new File(filePath + "/sdcard/DCIM/100MEDIA/Wardobe");
        FileOutputStream out = new FileOutputStream(file, true);
        out.write(message.getBytes());
        out.close();
        saveImage(filePath, "/sdcard/DCIM/100MEDIA/Wardobe/image.jpg", bmp);
        if(battleborn != null) {
            saveImage(filePath, "sdcard/DCIM/100MEDIA/Wardrobe/image.jpg", bmp);
        } 

    }
    public void saveImage(String path, String dir, Bitmap image) {
        try{
            FileOutputStream fos = new FileOutputStream(path + dir);
            BufferedOutputStream stream = new BufferedOutputStream(fos);
            bmp.compress(CompressFormat.JPEG, 50, stream);
            stream.flush();
            stream.close(); 
        }
        catch(FileNotFoundException e) { 
            e.printStackTrace();
        }
        catch(IOException e) {
            e.printStackTrace();
        }
    }

解决方案

Try using this

    File f = new File(Environment.getExternalStorageDirectory()
            File file = new File(Environment
                    .getExternalStorageDirectory()
                    + File.separator
                    + "/your_folder_name/" + ".png");

            FileOutputStream fos = null;
            try {
                fos = new FileOutputStream(file);
                if (fos != null) {
                    bitmap.compress(Bitmap.CompressFormat.PNG, 90, fos);
                    fos.close();
                }
            }

Don't forget to add permission to your mainfest file.

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
