Question

当我在onActivityResult并且我尝试显示自定义进度对话框时，
对话框未显示，但调用了该功能，但未显示任何内容如果我把这个对话框放在Oncreate中它正在工作，我会看到对话框，是否可以在返回Intent.ACTION_GET_CONTENT / MediaStore.ACTION_IMAGE_CAPTURE

时显示自定义对话框

由于

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  Parseur UploadPhoto = new Parseur();
  showDialog(PROGRESS_DIALOG);
  if (requestCode == z_const.REQUEST_INTENT_CODE_PHOTO_CHOISIR) {
   String selectedImagePath;
   Uri selectedImageUri;
   if (data != null){
    selectedImageUri = data.getData();
    selectedImagePath = getPath(selectedImageUri);
    Log.e(TAG, "PHOTO CHOISIR " + selectedImagePath+"Res"+resultCode);
    UploadPhoto.uploadPhoto(InfoPasse,selectedImagePath);
   }
  }
  finish();
 }

 protected Dialog onCreateDialog(int id) {
  Log.e(TAG," DIAL appeller "+id);
  switch(id) {
  case PROGRESS_DIALOG:
   progressDialog = new ProgressDialog(Photo.this);
   progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
   progressDialog.setMessage("Loading...");
   progressThread = new ProgressThread(handler);
   progressThread.start();
   return progressDialog;
  default:
   return null;
  }
 }

在doInBackground中的AsyncTask中播放loking任务
在致电意图之前启动对话

所以替换loking任务UploadPhoto.uploadPhoto（InfoPasse，selectedImagePath）;
通过new UploadInBackground（）。execute（selectedImagePath）; 和AsyncTask看起来像：

private class UploadInBackground extends AsyncTask<String, Integer, Long> {
@Override
protected Long doInBackground(String... params) {
    UploadPhoto.uploadPhoto(InfoPasse,params[0]);
    return null
}

@Override
protected void onProgressUpdate(Integer... progress) {
}

@Override
protected void onPostExecute(Long result) {
    finish();
}

}

Android：拍摄照片后，showAialog不在onActivityResult内显示器
