首页 > 解决方案 > Cannot control Progressbar visibility from onActivityResult in Fragment

问题描述

I have a Fragment which contains a Progressbar. I retrieve it in onCreateView() method where setVisibility() works fine.

Now, when I try to set visibility of the same progressbar (declared in fragment at class level) inside onActivityResult() nothing happens. Here is the code.

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
if(requestCode == REQUEST_CODE_PROFILE_VIDEO_PATH){
        if(resultCode == Activity.RESULT_OK) {
            String profileVideoPath = data.getExtras().getString(ProfileVideoRecordingActivity.VIDEO_PROFILE_PATH);
            Log.d("DEBUG", profileVideoPath);

            //Upload to server
            File profileVideo = new File(profileVideoPath);
            if(profileVideo.exists()) {

                pbarVideoUpload.setVisibility(View.VISIBLE);
                FireBaseWrapper fileUploader = new FireBaseWrapper();
                String serverFolderPath = "videoprofile";
                String contentType = "video/mp4";
                FireBaseAfterUpload afterUpload = new FireBaseAfterUpload() {
                    @Override
                    public void onSuccess(String uploadURL) {
                        Log.d("DEBUG", "Successfully uploaded video to server");
                        Log.d("DEBUG", uploadURL);
                        pbarVideoUpload.setVisibility(View.GONE);

                        ProfileService profileService = new ProfileService(TAG) {
                            @Override
                            protected void onPreServiceCall() {

                            }

                            @Override
                            protected void onPostServiceCall() {

                            }

                            @Override
                            public void afterSuccess(Object object) {
                                ReturnCode successCode = (ReturnCode) object;
                                if(successCode.getSuccess()){
                                    Log.d("DEBUG", "Profile Video URL updated in DB");
                                }else{
                                    Log.d("DEBUG", "Profile Video URL NOT updated in DB");
                                }
                            }

                            @Override
                            public void afterError() {
                                Log.d("DEBUG", "Profile Video URL NOT updated in DB");
                            }
                        };
                        profileService.updateVideoPath(uploadURL);

                    }

                    @Override
                    public void onProgress(String data) {

                    }

                    @Override
                    public void onFaliure() {
                        Log.d("DEBUG", "Error! Didn't upload");
                        pbarVideoUpload.setVisibility(View.GONE);
                    }
                };

                try {
                    fileUploader.upload(profileVideo, profileVideo.getName(), serverFolderPath, afterUpload, contentType, false);
                }catch (FileNotFoundException e){
                    Log.e("DEBUG", "FileNotFoundException", e);
                }
            }

        }
    }
}

I tried calling setVisibility() inside an Handler and also on UI thread using runOnUiThread(). Both approaches didn't work.

How can I control visibility of progressbar inside onActivityResult() of Fragment?

I need it as I am uploading a file inside onActivityResult() and need to display progress.

我认为你 onActivityResult 没有像在片段中那样触发。请在包含片段的活动中使用以下代码。

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
Fragment fragment = (Fragment) getSupportFragmentManager().findFragmentByTag(fragmentTag);
if (fragment != null) {
    fragment.onActivityResult(requestCode, resultCode, intent);
}
}
