QUESTION
I have a button method that expects me to give it a value from the field that serves as the ID.
...ANSWER
Answered 2021-May-15 at 08:57If I understand your question, first you have to bind your text field into a Person property in your ViewModel then use the Person Object in your Event handler.

Well... I don't know where to start with this... I'm doing a course where the teacher has not taught us anything about databases and now he want us to do an app with kotlin and sqlite where we make an Activity with a button "New table" where user can create a database table with a name and dynamic fields. I've been searching all day about it and I got nothing.
I thought about create a CRUD but I'm with the trouble that I don't know how to make any of this dynamically.
For now I have this SQLiteHelper that I saw it was necessary to make and I put const values to test it because I don't have any clue how to pass the values from the user view.
...ANSWER
Answered 2021-Apr-09 at 09:02You first issue that you will encounter is that you are trying to create a table using CREATE TABLE TABLE_NAME (COL_1 PRIMARY KEY AUTOINCREMENT .....
The table that will be created (attempted) will be TABLE_NAME not Testing_Table as the variable name is embedded within the String rather than being resolved and appended to the string.
There are multiple inclusions of variables in Strings.
Another error is that you have PRIMARY KEY AUTOINCREMENT autoincrement can only be used for an alias of the rowid which must be defined using specifically INTEGER PRIMARY KEY.
You don't need AUTOINCREMENT as INTEGER PRIMARY KEY will do what you want (increment the value of the ID column so the first will be 1, then likely 2, then likely 3 ....). AUTOINCREMENT is basically a constraint/rule that says the number MUST be higher (for your testing it will be (not that it really matters)).
I'd suggest the following that is based upon your code (but without the click handling) that successfully creates the table, inserts some rows (not tables) in the table and then extracts them and writes the extracted data to the log.
First the modified AdminSQLiteOpenHelper :-
QUESTION
I'm currently developing a two-way dictionary application for Android using SQLite + Room. By two-way, I mean a user can search in either language and obtain relevant results.
A key feature I would like to implement is to allow the user to not have to toggle the current language being used to search. E.g. they shouldn't have to press a button to search in Language X or Language Y.
Unfortunately, at least to my limited knowledge, this means I have to conduct search using only one query.
My database is currently set up as follows (I can change schema if required):
The number of rows in Words is ~129,000 and Glosses is ~150,000.
Here gloss means translation with each word have multiple glosses, and pos means part of speech. All fields are TEXT except ids. I am using Room to access my database.
Currently I have a very (I assume to be at least) naive bit of SQL in my DAO that gets me what I want:

Suposse that i have an android studio App where i can add companies, and inside those companies i can also add employees. Now, i'm trying to get the employees list showing only the elements of the company I selected before (In an unique activity for showing employees).
I created two classes:
...ANSWER
Answered 2020-Nov-26 at 14:25First you have to obtain companyId you want to filter by. It can be done for example by adding onClickListener in RecyclerView.
Then you will need additional query which will be used for filtering by companyId.
For example if companyId is stored in filteredCompanyId variable you can add additional filter condition (WHERE ... AND C.$COMPANY_ID == $filteredCompanyId):
QUESTION
I am trying to build a listview which contains outlet address in 5 lines,along with a status indicator image and a button. The following is the functionality I am trying to build.
- When the list text is clicked - I want to open a activity.
- When the button (COMP) is clicked - I want to open a different activity.
The image (tickmark) is a status indicator to inform the user whether the activity in a outlet is complete or not.
The list is populated from a SqliteDatabase. On clicking the button, I want to take the reference of the outlet and show different attributes of the outlet.
How do I integrate the button into the list view.
I have written the following code so far:
LISTVIEW.XML
...ANSWER
Answered 2020-Nov-17 at 04:40first I have question. why don't you make Model for Items?
Anyway if you want to make click event by element, just add click listener in your adapter.
so Example is here
add id in your whole layout. ( android:id="@+id/layout" )

I want to make an SqliteHelper that would force any user to close properly the connexion after executing a query.
Is there a pattern that would ensure this ?
...ANSWER
Answered 2020-Nov-05 at 08:59What you could try is to make helper methods that require the user actions to be supplied as a lambda expression or method reference. I'm not sure how you're connecting to SQLite, so I'll use JDBC classes in my example:
QUESTION
I'm trying to create a Class to manage my Cloud Firestore requests (like any SQLiteHelper Class). However, firebase uses async calls and I'm not able to return a value to other scripts. Here an example (bool return):
...ANSWER
Answered 2020-Jun-29 at 17:57Unfortunately, since Firestore is acting as a frontend for some slow running I/O (disk access or a web request), any interactions you have with it will need to be asynchronous. You'll also want to avoid blocking your game loop if at all possible while performing this access. That is to say, there won't be a synchronous call to GetSnapshotAsync.
Now there are two options you have for writing code that feels synchronous (if you're like me, it's easier to think like this than with callbacks or reactive structures).
First is that GetSnapshotAsync returns a task. You can opt to await on that task in an async function:
QUESTION
In my app I have a queue with items in a database that should be sent to a server. Since I want this queue to be monitored continuously and since this task includes network communication I have made a class that implements Runnable that I call my QueueWorkerThread. But for some reason I still get the "android.os.NetworkOnMainThreadException" and I don't understand why? I've tried searching for similar issues here on SO, but anything even close is using AsyncTask and since that class apparently will become depricated in API level 30 I don't want to use it (I want this app to work for a long time). Is my Runnable somehow running something back on the main thread? Is that even possible?
Here's the code for my QueueWorker Thread:
...ANSWER
Answered 2020-Jun-25 at 13:11In the else part, you are calling run methods directly which will execute the network call on mail thread, hence the exception
