How to make history score in Array
I try u make score in array like this
this my firestore
And this is my code
String uid = auth.getCurrentUser().getUid();
muridref.document(uid).update("nilai", FieldValue.arrayUnion(skortampil));
When I get the same score the array field doesn't make new Array data,
without see data there or not in array
As mentioned in the documentation Update elements in an array about this behavior:
If your document contains an array field, you can use arrayUnion() and arrayRemove() to add and remove elements. arrayUnion() adds elements to an array but only elements not already present.
Considering that, it's working as expected, since it's not adding values that are equal. So, this means that you won't be able to add values that are equal using the method arrayUnion() directly.
This other question from the Community - accessible here - indicates that for you to achieve this goal, you will need to read all the values from the array in your client side, update your values in the array outside the database and then, writing/updating it back in the database.
Let me know if the information helped you!

In my project, I need to display data like this in a single text view.
This means that all data will be stored in a single string.
Because also need to print same view.
Can you please tell me how I can make this kind of string/output?
Use subString method to split the string using the spaces in between or any logic u preferred and the place the subString values in tableLayout and place images for lines.
It is not efficient using single textview to display all your data.
You can split your data string and then you distribute them into table layout
or you can just use a webview and write your data as HTML in a single string
if you use one of them, you can also keep your data string and you can print as you wish.
I have one json file, that I imported in parse.com->data browser->import partition. I can get the String and image value from the table but I have no idea about how to get following values. First column have name chapters of type array look like one field following,
[{"__type":"Pointer","className":"Chapter","objectId":"BCr3uAnapV"}]
how to get above value and second column have, name user of type object look like following,
{"password":"xxx"}
Please any one help me for above, I have tried Googling but it did not help.
EDIT:
See following screen shot: arrow display column 1) chapter and have another column 2) user I want to fetch (get ) that for e.g. if we want to get data of String type like: String provider = (String) objectList.get(i).get("provider"); this manner this way I want to above data, below my screen shot:
This line is a relation (of type Pointer) to another Class in Parse:
[{"__type":"Pointer","className":"Chapter","objectId":"BCr3uAnapV"}]
The class being Chapter. You can make sure this object is fetched together with the object pointing to it using "include":
query.include("chapter");
When you query for the other object, using query.include on pointer relations will ensure these related objects are fetched as well.
I am facing a problem in solving this issue.
I have 30 smiley images. In a grid view I display all the 30 images. So when I select the image based on the position of the image, the corresponding special character will be displayed from SQLite DB. Before I send message to service it is like "hi :)". What I need is to replace the ":)" with the corresponding smiley image in the local folder of my project (eg. R.drawable.facea.png). I am able to fetch the data and replace ":)" with "aaaaa"(example). But when I try to replace the ":)" with Char Sequence (Image), I get 'force close error'. Where am I going wrong?
I have a function to draw image and I get image as in Character Sequence. How can I use the value in this function globally. I also tried to create a global variable and use the CS value globally. But I still get 'force close error.
You need to use a span (specifically an ImageSpan) to be able to embed bitmap in a string. I have written about this on my blog which also covers some common pitfalls.
If you still cannot get it to work I would suggest posting the precise details of what is going wrong: i.e. your code, and the stacktrace that is getting dumped to logcat.
I have a working android app using TextView, some formatting (line breaks, rows of dashes) and Linkify to generate a primitive "ListView-like" display with clickable URLs in each "row". I'd like to move up to a real ListView, but I'm just not finding the sample/explanation that I need to take that next step.
I have successfully reproduced the HelloListView sample, starting with the hardcoded string array, and moving to a string array defined in my res/values/strings.xml. I've taken one small step toward my goal by adding my HttpClient code to retrieve a set of data from a service, parse the results into a String Array and feed that into setListAdapter() such that my text and links show up as text-only in ListView items.
I want to move to the next step which is to make each "row" in my ListView launch the browser to the URL contained in the data, either by
(A) clicking anywhere in the row, or
(B) clicking a hyperlink displayed within the row data
For option (A), it appears that I need to have my onItemClick() method issue an intent that launches the browser. That's straightforward, but I don't get how to associate the URL with the item (currently its just one part of the string content for each "row" of text). How do I separate my URL from the rest of the text, such that I can launch a browser to the corresponding URL? Do I need to replace my String Array with an array of custom objects?
For option (B), can I use Linkify? It seems that my string array elements get converted to individual TextViews (inferring from the way the Toast text is generated in the HelloListView sample). Do I have access to that TextView to run Linkify against? Do I need to replace my String Array with a TextView Array and run Linkify myself? Am I completely off base?
Thanks to anyone who can help explain back to me what I'm trying to do, in a way that helps to find my way around the SDK, samples and other helps!
How do I separate my URL from the rest of the text, such that I can launch a browser to the corresponding URL?
Use a regular expression (java.util.regex) to find the URL.
For option (B), can I use Linkify?
Yes.
Do I have access to that TextView to run Linkify against?
Yes. Override getView() in your ArrayAdapter. Chain to the superclass and get your TextView from the result of super.getView().
Even better would be to use Linkify on your strings before putting them in the array in the first place.
Do I need to replace my String Array with a TextView Array and run Linkify myself?
No, and that is really not a good idea. Here is a free excerpt from one of my books that goes into more detail on tailoring the individual rows of a ListView, in case this helps.
