Android 解决相机拍照后在三星手机上翻转的问题(完美运行)

老规矩,先上效果图(虽然说不是很形象吧):

1.首先我们获取一下相机拍照后翻转的角度

/**
     * 读取照片exif信息中的旋转角度
     * @param path 照片路径
     * @return角度
     */
    public static int readPictureDegree(String path) {
        //传入图片路径
        int degree = 0;
        try {
            ExifInterface exifInterface = new ExifInterface(path);
            int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
            switch (orientation) {
                case ExifInterface.ORIENTATION_ROTATE_90:
                    degree = 90;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_180:
                    degree = 180;
                    break;
                case ExifInterface.ORIENTATION_ROTATE_270:
                    degree = 270;
                    break;
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return degree;
    }

2.上面方法返回的就是旋转的角度,然后我们将他按照角度在重新翻转回来,返回的是Bitmap对象

    //旋将旋转后的图片翻转
    public static Bitmap toturn(String path, int degree){
        Bitmap img = BitmapFactory.decodeFile(path);
        Matrix matrix = new Matrix();
        matrix.postRotate(degree); /*翻转90度*/
        int width = img.getWidth();
        int height =img.getHeight();
        img = Bitmap.createBitmap(img, 0, 0, width, height, matrix, true);
        return img;
    }

3.我们要定义两个变量为本地存储的路径

    private static final String SD_PATH = "/sdcard/dskqxt/pic/";
    private static final String IN_PATH = "/dskqxt/pic/";

4.然后随机去获取文件名字

/**
     * 随机生产文件名
     * @return
     */
    private static String generateFileName() {
        return UUID.randomUUID().toString();
    }

5.最后将Biamap传入这个方法,返回的就是本地存储的路径

    //将bitmap对象写到本地路径
    public static String saveBitmap(Context context, Bitmap mBitmap) {
        String savePath;
        File filePic;
        if (Environment.getExternalStorageState().equals(
                Environment.MEDIA_MOUNTED)) {
            savePath = SD_PATH;
        } else {
            savePath = context.getApplicationContext().getFilesDir()
                    .getAbsolutePath()
                    + IN_PATH;
        }
        try {
            filePic = new File(savePath + generateFileName() + ".jpg");
            if (!filePic.exists()) {
                filePic.getParentFile().mkdirs();
                filePic.createNewFile();
            }
            FileOutputStream fos = new FileOutputStream(filePic);
            mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
            fos.flush();
            fos.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
            return null;
        }
        return filePic.getAbsolutePath();
    }

6.现在我们直接就可以拿5返回的String类型的图片路径去操作就可以了
