I'm fairly new with Android development so I'm just trying some concepts.
For this POC I took the first 20 values from this IMDB list => https://www.imdb.com/chart/toptv/
added them into a JSON which is inside the assets folder of my project.
I have a method in my main activity to access the content of the JSON file, it goes like this:
public void readMovies() {
String jsonFileString = Utils.getJsonFromAssets(getApplicationContext(), "movies.json");
Log.i("data", jsonFileString);
Gson gson = new Gson();
Type listUserType = new TypeToken<List<Movies>>() { }.getType();
List<Movies> movies = gson.fromJson(jsonFileString, listUserType);
for (int i = 0; i < movies.size(); i++) {
Log.i("data", "> Item " + i + "\n" + movies.get(i));
}
}
Using a textView I'm able to output all the titles (for example) in the layout, but I'd like to be able to display a view similar to the IMDB page, with an image to the left side, title on the centre and any other property on the right side.
How can I achieve a view like the shared URL?
You've to create a Listview with images and text. Attaching some resources.

Check out this Youtube tutorial or this one.
These are the ones I found which provide a code walk-through. But now you know the keywords to search for, you can find resources on your own!

I have this JSON data
"posts":[{
"date":"2016-02-10 10:28:42",
"categories":[{}],
"tags":[],
"author":{"name":"admin"},
"custom_fields":{
"ref_number":["ITB NUMBER: ITB\/002\/2016"],
"deadline":["26 February, 2016"],
"entity":["Refugees (xxx)"]
}
I want to pass entitywith the code below in my JSONParser.java
Post post = new Post();
// Configure the Post object
post.setTitle(postObject.optString("title"));
post.setDate(postObject.optString("date", "N/A"));
post.setContent(postObject.optString("content", "N/A"));
post.setCfs(postObject.getJSONObject("custom_fields").optJSONArray("entity").getString(0));
to my Webview. using the code below in my PostFragment.java
id = args.getInt("id");
//Title and date pass successfully
title = args.getString("title");
String date = args.getString("date");
//but the entity displays null
entity = args.getString("entity");
//author is passed and it displays well/successfully
String author = args.getString("author");
// Construct HTML content
// html for entity to webview
html += "<h2>" + entity + "</h2>";
html += "<h3>" + title + "</h3>";
// The actual content
html += content;
am able to pass and display title and content, however when i try entity it shows null in webview
Where am i going wrong
Try:
entity = args.getString("custom_fields.entity");
Hope it helps!
Your question is not clear , as per my understanding you need Refugee element
The JSON you have posted is not valid.
As per my understanding elements of entity is also an JSONObject , so the parser should be like this
.optJSONArray("entity").getJSONObject(i); // i is poistion
This will give you ith element of entity array
I am using the YouTube Data API V3 in Java and I am trying to "like" a video. I am using the following method:
private static String insertPlaylistItem(String playlistId, String videoId) throws IOException {
// Define a resourceId that identifies the video being added to the
// playlist.
ResourceId resourceId = new ResourceId();
resourceId.setKind("youtube#video");
resourceId.setVideoId(videoId);
// Set fields included in the playlistItem resource's "snippet" part.
PlaylistItemSnippet playlistItemSnippet = new PlaylistItemSnippet();
playlistItemSnippet.setTitle("First video in the test playlist");
playlistItemSnippet.setPlaylistId(playlistId);
playlistItemSnippet.setResourceId(resourceId);
// Create the playlistItem resource and set its snippet to the
// object created above.
PlaylistItem playlistItem = new PlaylistItem();
playlistItem.setSnippet(playlistItemSnippet);
// Call the API to add the playlist item to the specified playlist.
// In the API call, the first argument identifies the resource parts
// that the API response should contain, and the second argument is
// the playlist item being inserted.
YouTube.PlaylistItems.Insert playlistItemsInsertCommand =
youtube.playlistItems().insert("snippet,contentDetails", playlistItem);
PlaylistItem returnedPlaylistItem = playlistItemsInsertCommand.execute();
System.out.println("New PlaylistItem name: " + returnedPlaylistItem.getSnippet().getTitle());
System.out.println(" - Video id: " + returnedPlaylistItem.getSnippet().getResourceId().getVideoId());
System.out.println(" - Posted: " + returnedPlaylistItem.getSnippet().getPublishedAt());
System.out.println(" - Channel: " + returnedPlaylistItem.getSnippet().getChannelId());
return returnedPlaylistItem.getId();
}
The Method above came from the official YouTube Example located here:
https://developers.google.com/youtube/v3/docs/playlists/insert?hl=de#examples
I go the hint that I have to add the video to the "liked" playlist, which automatically adds a like to that video.
Here is how I get the Playlist for Likes
....
String likesPlaylistId = channelsList.get(0).getContentDetails().getRelatedPlaylists().getLikes();
insertPlaylistItem(likesPlaylistId, "pwi9TAKUMYI" );
If I like a video that I uploaded myself, it works. But If I try to like a video that another youtuber uploaded, the following error appears:
http://pokit.org/get/?d25a148b2a20d169488cf167d22ad7b0.jpg
I see the video as "liked" but the like counter isn't increasing. Noone else can see that like. Can anyone tell me what I am doing wrong? Is that a restriction? Or is it a prevention against Bots?
Have you tried actually getting the rating of a video? (https://developers.google.com/youtube/v3/docs/videos/getRating).
Get the rating of the video before and after liking the video and then you can verify if the rating count increased. There might be a graphical delay.
raw api call is :
GET https://www.googleapis.com/youtube/v3/videos/getRating?id=pwi9TAKUMYI&key={YOUR_API_KEY}
I have a form that runs a java agent on the WebQueryOpen event. This agent pulls data from a DB2 database and then puts them into the computed text fields I have placed on the form and are displayed whenever I open the form in the browser. This is working for me. However, when I try to use RichTextFields I get a ClassCastException error. No document is actually saved, I just open the form in the browser using this domino URL - https://company.com/database.nsf/sampleform?OpenForm
Sample code of simple text field - Displayed with w/o problems
Document sampledoc = agentContext.getDocumentContext();
String samplestr = "sample data from db2";
sampledoc.replaceItemValue("sampletextfield", samplestr);
When I tried using rich text field
Document sampledoc = agentContext.getDocumentContext();
String samplestr = "sample data from db2";
RichTextItem rtsample = (RichTextItem)sampledoc.getFirstItem('samplerichtextfield');
rtsample.appendText(samplestr); // ClassCastException error
Basically, I wanted to use rich text field so that it could accommodate more characters in case I pull a very long string data.
Screenshot of the field (As you can see it's a RichText)
The problem is that you're trying to access a regular Item as a RichTextItem.
The RichTextItem are special fields that are created with its own method just like this:
RichTextItem rtsample = (RichTextItem)sampledoc.createRichTextItem('samplerichtextfield');
It's different to the regular Items that can be created with a simple sampledoc.replaceItemValue(etc).
So, if you want to know if a item is RichTextItem and if it does not exist, create it, you can do this:
RichTextItem rti = null;
Item item = doc.getFirstItem("somefield");
if (item != null) {
if (item instanceof RichTextItem) {
//Yay!
rti = (RichTextItem) item;
} else {
//:-(
}
} else {
rti = doc.createRichTextItem("somefield");
//etc.
}
I am creating PPT files using the library docx4j. I have been able to create slides with text and images, but I have not been able to add notes to them.
I am creating the slide like this:
MainPresentationPart pp = (MainPresentationPart)presentationParts.get(new PartName("/ppt/presentation.xml"));
SlideLayoutPart layoutPart = (SlideLayoutPart)presentationParts.get(new PartName("/ppt/slideLayouts/slideLayout1.xml"));
SlidePart slidePart = PresentationMLPackage.createSlidePart(pp, layoutPart, new PartName("/ppt/slides/slide" + ++slideNumber + ".xml"));
so I can add text or images to the body, but when I try to access the field slidePart.notes it is null. I have tried to initialize it
slidePart.setPartShortcut(new NotesSlidePart());
but then everything inside notes is null and I have not achieved anything.
So, does anyone have a working example of how to add notes to a PPT file?
Many thanks
Its not enough to do:
slidePart.setPartShortcut(new NotesSlidePart());
You need to explicitly add the notes slide part to your slide part (so that the relationships get set up correctly), by invoking addTargetPart.
But there's more you have to do given the way the pptx format works. To see what parts are required, upload a pptx to the docx4j webapp. Here's the code I wrote just now based on doing that:
// Now add notes slide.
// 1. Notes master
NotesMasterPart nmp = new NotesMasterPart();
NotesMaster notesmaster = (NotesMaster)XmlUtils.unmarshalString(notesMasterXml, Context.jcPML);
nmp.setJaxbElement(notesmaster);
// .. connect it to /ppt/presentation.xml
Relationship ppRelNmp = pp.addTargetPart(nmp);
/*
* <p:notesMasterIdLst>
<p:notesMasterId r:id="rId3"/>
</p:notesMasterIdLst>
*/
pp.getJaxbElement().setNotesMasterIdLst(createNotesMasterIdListPlusEntry(ppRelNmp.getId()));
// .. NotesMasterPart typically has a rel to a theme
// .. can we get away without it?
// Nope .. read this in from a file
ThemePart themePart = new ThemePart(new PartName("/ppt/theme/theme2.xml"));
// TODO: read it from a string instead
themePart.unmarshal(
FileUtils.openInputStream(new File(System.getProperty("user.dir") + "/theme2.xml"))
);
nmp.addTargetPart(themePart);
// 2. Notes slide
NotesSlidePart nsp = new NotesSlidePart();
Notes notes = (Notes)XmlUtils.unmarshalString(notesXML, Context.jcPML);
nsp.setJaxbElement(notes);
// .. connect it to the slide
slidePart.addTargetPart(nsp);
// .. it also has a rel to the slide
nsp.addTargetPart(slidePart);
// .. and the slide master
nsp.addTargetPart(nmp);

I'm trying to parse RSS/Atom feeds with the ROME library. I am new to Java, so I am not in tune with many of its intricacies.
Does ROME automatically use its modules to handle different feeds as it comes across them, or do I have to ask it to use them? If so, any direction on this.
How do I get to the correct 'source'? I was trying to use item.getSource(), but it is giving me fits. I guess I am using the wrong interface. Some direction would be much appreciated.
Here is the meat of what I have for collection my data.
I noted two areas where I am having problems, both revolving around getting Source Information of the feed. And by source, I want CNN, or FoxNews, or whomever, not the Author.
Judging from my reading, .getSource() is the correct method.
List<String> feedList = theFeeds.getFeeds();
List<FeedData> feedOutput = new ArrayList<FeedData>();
for (String sites : feedList ) {
URL feedUrl = new URL(sites);
SyndFeedInput input = new SyndFeedInput();
SyndFeed feed = input.build(new XmlReader(feedUrl));
List<SyndEntry> entries = feed.getEntries();
for (SyndEntry item : entries){
String title = item.getTitle();
String link = item.getUri();
Date date = item.getPublishedDate();
Problem here --> ** SyndEntry source = item.getSource();
String description;
if (item.getDescription()== null){
description = "";
} else {
description = item.getDescription().getValue();
}
String cleanDescription = description.replaceAll("\\<.*?>","").replaceAll("\\s+", " ");
FeedData feedData = new FeedData();
feedData.setTitle(title);
feedData.setLink(link);
And Here --> ** feedData.setSource(link);
feedData.setDate(date);
feedData.setDescription(cleanDescription);
String preview =createPreview(cleanDescription);
feedData.setPreview(preview);
feedOutput.add(feedData);
// lets print out my pieces.
System.out.println("Title: " + title);
System.out.println("Date: " + date);
System.out.println("Text: " + cleanDescription);
System.out.println("Preview: " + preview);
System.out.println("*****");
}
}
getSource() is definitely wrong - it returns back SyndFeed to which entry in question belongs. Perhaps what you want is getContributors()?
As far as modules go, they should be selected automatically. You can even write your own and plug it in as described here
What about trying regex the source from the URL without using the API?
That was my first thought, anyway I checked against the RSS standardized format itself to get an idea if this option is actually available at this level, and then try to trace its implementation upwards...
In RSS 2.0, I have found the source element, however it appears that it doesn't exist in previous versions of the spec- not good news for us!
[ is an optional sub-element of 1
Its value is the name of the RSS channel that the item came from, derived from its . It has one required attribute, url, which links to the XMLization of the source.
