下面是解决方案:

最后只需要在需要的地方调用showSettingFaceDialog()就可以了。
如果要获得剪裁的图片保存路径,然后上传,我这边是这样处理的(这里每个人的写法不一样):
但只要获得filePath就可以根据自己的需求处理了
private void uploadFace(){ File file = new File(Environment.getExternalStorageDirectory(),IMAGE_FILE_NAME); String filePath=file.getAbsolutePath(); Log.i("tag", "filePath="+filePath); HttpHelper.uploadFileWithConcatUrl(context,HttpHelper.UPDATE_USER_ICON,App.user.getUser_session_key() ,filePath ,new HttpHelper.OnFileUploadListener(){ @Override public void onFileUploadSuccess(String orignUrl, String midImgUrl, String smallImgUrl) { // TODO Auto-generated method stub App.user.setHead_icon(orignUrl); saveUser(); } }); }
