首先声明参数：

public static final int TAKE_PHOTO = 2001;    public static final int GALLERY = 2002;

//照相

if (hasSDCard()) {                    getNewPath();                    Log.e(TAG, "拍摄的照片路径:" + path);                    Intent cameraIntent = new Intent("android.media.action.IMAGE_CAPTURE");                    cameraIntent.putExtra("scale", true);                    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment.getExternalStorageDirectory(), path)));                    startActivityForResult(cameraIntent, TAKE_PHOTO);                }//相册 Intent intentFromGallery = new Intent();                intentFromGallery.setType("image/*"); // 设置文件类型                intentFromGallery.setAction(Intent.ACTION_GET_CONTENT);                startActivityForResult(intentFromGallery, GALLERY);//onActivityResult(requestCode,resultCode,data)

//在此处来得到拍照返回的结果

switch (requestCode) {            case TAKE_PHOTO:                if (hasSDCard())                    presenter.setHead(FileUtils.getImageAbsolutePath(getActivity(), Uri.fromFile(new File(Environment.getExternalStorageDirectory(), path))));                break;            case GALLERY:                if (null != data) {                    String img_url = FileUtils.getImageAbsolutePath(getActivity(), data.getData());                    Log.e(TAG, "上传路径为:" + img_url);                    presenter.setHead(img_url);                }                break;           }

//是否有SD卡

 public boolean hasSDCard() {            return Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED);    }

重头戏来了：
由于android各个版本得到图片路径不一样，由此使用一个类来根据uri来得到路径

//根据uri来获得路径public class FileUtils {    @TargetApi(19)    public static String getImageAbsolutePath(Activity context, Uri imageUri) {        if (context == null || imageUri == null)            return null;        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT && DocumentsContract.isDocumentUri(context, imageUri)) {            if (isExternalStorageDocument(imageUri)) {                String docId = DocumentsContract.getDocumentId(imageUri);                String[] split = docId.split(":");                String type = split[0];                if ("primary".equalsIgnoreCase(type)) {                    return Environment.getExternalStorageDirectory() + "/" + split[1];                }            } else if (isDownloadsDocument(imageUri)) {                String id = DocumentsContract.getDocumentId(imageUri);                Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));                return getDataColumn(context, contentUri, null, null);            } else if (isMediaDocument(imageUri)) {                String docId = DocumentsContract.getDocumentId(imageUri);                String[] split = docId.split(":");                String type = split[0];                Uri contentUri = null;                if ("image".equals(type)) {                    contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;                } else if ("video".equals(type)) {                    contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;                } else if ("audio".equals(type)) {                    contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;                }                String selection = MediaStore.Images.Media._ID + "=?";                String[] selectionArgs = new String[]{split[1]};                return getDataColumn(context, contentUri, selection, selectionArgs);            }        } // MediaStore (and general)        else if ("content".equalsIgnoreCase(imageUri.getScheme())) {            // Return the remote address            if (isGooglePhotosUri(imageUri))                return imageUri.getLastPathSegment();            return getDataColumn(context, imageUri, null, null);        }        // File        else if ("file".equalsIgnoreCase(imageUri.getScheme())) {            return imageUri.getPath();        }        return null;    }    public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {        Cursor cursor = null;        String column = MediaStore.Images.Media.DATA;        String[] projection = {column};        try {            cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null);            if (cursor != null && cursor.moveToFirst()) {                int index = cursor.getColumnIndexOrThrow(column);                return cursor.getString(index);            }        } finally {            if (cursor != null)                cursor.close();        }        return null;    }    /**     * @param uri The Uri to check.     * @return Whether the Uri authority is ExternalStorageProvider.     */    public static boolean isExternalStorageDocument(Uri uri) {        return "com.android.externalstorage.documents".equals(uri.getAuthority());    }    /**     * @param uri The Uri to check.     * @return Whether the Uri authority is DownloadsProvider.     */    public static boolean isDownloadsDocument(Uri uri) {        return "com.android.providers.downloads.documents".equals(uri.getAuthority());    }    /**     * @param uri The Uri to check.     * @return Whether the Uri authority is MediaProvider.     */    public static boolean isMediaDocument(Uri uri) {        return "com.android.providers.media.documents".equals(uri.getAuthority());    }    /**     * @param uri The Uri to check.     * @return Whether the Uri authority is Google Photos.     */    public static boolean isGooglePhotosUri(Uri uri) {        return "com.google.android.apps.photos.content".equals(uri.getAuthority());    }    public static String savePicToSdcard(Bitmap bitmap, String path) {        String filePath = "";        if (bitmap == null) {            return filePath;        } else {            File destFile = new File(path);            OutputStream os = null;            try {                os = new FileOutputStream(destFile);                bitmap.compress(Bitmap.CompressFormat.JPEG, 100, os);                os.flush();                os.close();            } catch (IOException e) {                filePath = "";            }        }        return filePath;    }}

将路径传入presenter中，就可以将图片上传，设置，我用的是univasial-image-loader，就不贴代码了

还有一件重要的事情:在给imageview设置图片的时候，需要在路径前面加一个"file:///"，就像:`final String newHead = "file:///" + head;ImageLoader.getInstance().displayImage(newHead , listViewHolder.getIv_vehicle_img());

基本的流程就是这样了
