How can I read a single row from a sqlite database in android studio and put the data from each field in separate TextViews? E.G: Name in one text view, last name in another and so on.... So far the tutorials I have seen used recycler views and such because they are viewing multiple rows of the database, not just one....
I am quite new to this so please be as detailed as possible...Thanks!

I display my JSON data into a RecyclerView. I have multiple TextView into one item and it works perfectly.
In my data, I need to fetch photos and display them into each item. I have multiple photos for one item. It starts from 6 photos to... many more.
I tried using a RecyclerView inside my first RecyclerView but as you can guess it was a bad idea (bad performance, not the good result expected and so on).
Do you have any other solution or advice that might help, please?
I found a thousand solutions how to display one picture by row but none about multiple pictures into one row.
Create a custom view and add Image views dynamically based on no.of views required.
Use this view in the recycler view adapter itemlayout file.
I am building an Android app for a forum and the API they have created returns 'bbCode' for posts and private messages. Things like [b]bold text here[/b] for bold text and [spoiler]hidden text here[/spoiler] for hidden text which is then revealed by clicking a button of some kind. I am building a parser that will create a mapping between raw text some text to be hidden and type of component PostComponent.SPOILER for example.
How would I go about inflating this parsed and categorised data into multiple Android views dynamically, and then proceed to merge them into one view which will be displayed in a list (to display a list of posts like you see in a forum)?
I can think of a few hacks to get this done (like creating a layout for each post component and having each of them in a non-scrollable listview stacked on top of one another), but I can't quite think of a nice efficient solution.
I'm writing an Android app (4.2 and above) to return the details of an item from a location on a warehouse shelf.
The locations are fixed as an id for each cell of a HTML table. For example, the centre location has id="0,0". The HTML table is called from a WebView and will act as the GUI for the app. As such, I have three questions:
How can I get the HTML table to dynamically show the item for the corresponding record from the SQLite database?
How can I show the items on different shelves?
How would I make the cells selectable so that I can see further information about an item?
After a lot of searching, I've found posts on how to do this in Python, PHP and C, but nothing much in the way of doing it using Java/JavaScript.
As this is my first question, please let me know if you require any additional information. Cheers!
I'm kinda new to Android Programming. I'm trying to create a list of several objects. Each list item should look like this:
_________________________________________
| Title Text View | Edit |Delete|
| Secondary Title Text View |Button|Button|
Each list item represent an object which was read from a database. My question is, how do I keep the list dynamic according to additions, edits and deletes, which the user can perform?
I thought about reading the database into an array and then using array adpater, and when the programs finishes, writing it back into the database, but I cannot match the objects' fields into each text view (or atleast I don't know how).
I'm sorry if my question seems stupid, I'm really new to android.
I think what you want to do is create an adapter which holds the data that you got from the DB.
The data will be displayed using a ListView (this is the part that will display your attached sketch).
After you change the data in the DB, you should refresh the adapter using:
yourAdapter.notifyDataSetChanged();
So your ListView will reflect the changes.
To clarify this - what I want to do is:
a) to open a http request to obtain some XML
b) parse that XML
c) given the (fixed) number of elements, put them with a bucle in the layout.
What I am missing is the last part. An example is 'twicca' or just the official Twitter application, that fills the layout with tweets. I want to do something like that. How should I proceed?
My first thought was creating a fixed number of TextView and change those TextView (TextView1, TextView2, ...) with the content I wish. But that doesn't sound very professional...
The standard way to do this in Android is with a ListView (link to developer guide), which automatically creates as many items as needed from the data source. Most examples show pulling from a local SQLite database, but after you've loaded your XML items into an array in memory you can use an ArrayAdapter as the data source for the ListView.
