打开本地相册，获取照片

<span style="font-size:14px;">Intent intent = new Intent(Intent.ACTION_PICK, null);
intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,  "image/*");
startActivityForResult(intent, OPEN_PHOTO_REQUESTCODE);  //返回值是本地图片的URI

根据URI获取图片
ContentResolver cr = context.getContentResolver();
InputStream inputStream = null;
inputStream = cr.openInputStream(uri);
Bitmap result = BitmapFactory.decodeStream(inputStream, null, options);
inputStream.close();
</span>
