hello! How can i implement this view? https://stackoverflow.com/questions/63629460/paint-by-number-application-android

Hi all, is there anyone here that expert with making UI in kotlin? i need someone to enlighten on how to make this kind of cardview.

Hi! I'm trying to use the

rank

SQLite function in an FTS4 table query.

SELECT *
FROM launches
JOIN launches_fts ON launches.name = launches_fts.name
WHERE launches_fts MATCH "<query>"
ORDER BY rank(matchinfo(launches_fts));

The

launches_fts

table is an FTS4 table, implemented as:

CREATE VIRTUAL TABLE launches_fts USING FTS4(name TEXT NOT NULL, details TEXT, content=launches);

The problem is that whenever I try to run this query, I get the following error:

Result: wrong number of arguments to function rank()
At line 1:
SELECT name
FROM launches_fts 
WHERE launches_fts MATCH "*star*"
ORDER BY rank(matchinfo(launches_fts)) DESC;

This query matches the query given in the official documentation here: https://www.sqlite.org/fts3.html#matchinfo Can someone point out what I'm doing wrong?

@nickbutcher, May I ask a question. I have a requirement where the buttons in my app doesn't match the Theme's Primary Color... In current theming we do a way with this by setting a theme overlay on our button theme and setting it in styles so all button gets the set color like:

<style name="MyTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
        ...
        <item name="materialButtonStyle">@style/Widget.MyButton</item>
        <item name="materialButtonOutlinedStyle">@style/Widget.MyButton.Outlined</item>
        ...
</style>

<!--Buttons Styles-->
<style name="ThemeOverlay.MyButton" parent="">
        ...
        <item name="colorPrimary">@color/mycolor</item>
        <item name="colorOnPrimary">@color/myOnColor</item>
        ...
</style>

<style name="Widget.MyButton" parent="Widget.MaterialComponents.Button">
        <item name="materialThemeOverlay">@style/ThemeOverlay.MyButton</item>
        ...
</style>

....

But in

Jetpack Compose

there is no

styles

to set. Is it correct to instead of using the

Button

directly, simply create a "`MyButton` " and use it instead like:

@Composable
fun MyButton(
    ....
    modifier = Modifier,
) {
   Button(modifier = modifier.backgroundColor(myColor)
        ....
}

or is there a better and correct way to do this?

class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
    init {
        itemView.setOnClickListener {
            val intent = Intent(itemView.context, ListFragment::class.java)

            itemView.context.startActivity(intent)

        }
    }

}

why is it giving me an error message saying i need to declare fragment into manifest file? is it because of the intent?

i am using navigation, fragments, & recyclerviews

Hello there, I am trying to programming an app based on SOLID principles, and sometimes I see that my ViewModel is doing a lot of work(More than it should) and I would like to know what do I need to avoid this? Should I have one ViewModel for each fragment? or they can share based on the lifecycle? Thanks in advance.

I'm working on an Android app where I have ViewModel arch component and I observe a liveData in my fragment. I want to have a countdown textView that counts from 50 to 0 and "ticks" every second. I plan on doing this by having this coroutine

viewModelScope.launch {
            var initVal = 100
            repeat(100) {
                _myViewData.value =
                    _myViewData.value?.copy(initVal.toString())
                initVal--
                delay(1000)
            }
        }

Is there anything really bad with this approach? The only thing I can think of is how would the ViewModel being cleared would affect this.

Hey. In a Compose Codelab by @Sean McQuillan [G], I came across this ViewModel class:

class HelloCodelabViewModel: ViewModel() {

   // LiveData holds state which is observed by the UI
   // (state flows down from ViewModel)
   private val _name = MutableLiveData("")
   val name: LiveData<String> = _name

   // onNameChanged is an event we're defining that the UI can invoke
   // (events flow up from UI)
   fun onNameChanged(newName: String) {
       _name.value = newName
   }
}

class HelloCodeLabActivityWithViewModel : AppCompatActivity() {
   val helloViewModel by viewModels<HelloCodelabViewModel>()

   override fun onCreate(savedInstanceState: Bundle?) {
       /* ... */

       binding.textInput.doAfterTextChanged {
           helloViewModel.onNameChanged(it.toString()) 
       }

       helloViewModel.name.observe(this) { name ->
           binding.helloText.text = "Hello, $name"
       }
   }
}

I have two questions. 1- Why is

_name

not defined public so that it can be directly observed rather than through

name

? 2- How can

name

be modified using observe while it is defined as immutable (val)?

I guess LiveData is not immutable, right?

Hello guys, I want to know if it’s worth investing in instrumental testing in Android, Do I need to write them, keeping in mind how much time to spend maintaining them.

Hi, We have implemented an XMPP chat server with Prosody. and i want to connect this Xmpp server to send and receive messages. but I got error in connecting to this server via smack library. here is my code to connect:

private fun initChat() = GlobalScope.launch {
    initConnection()
}

private fun initConnection() {
    val config = XMPPTCPConnectionConfiguration.builder()
        .setXmppDomain("my domain")
        .setHost("my domain")
        .setSecurityMode(ConnectionConfiguration.SecurityMode.disabled)
        .setCompressionEnabled(false)
        .setPort(5280)
        .build()
    
    val connection = XMPPTCPConnection(config)
    connection.connect()
    connection.login()
}

and there are my gradle dependency:

i need to start my app from broadcast receiver/ service. i use this intent for it:

val intent = Intent(context, SplashScreen.class).apply{
 addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
 setAction(Intent.ACTION_MAIN)
 intent.addCategory(Intent.CATEGORY_LAUNCHER)
}
startActivity(intent);

but seem it not working. some one can tell me reason why and give me solution for it!?

Is this how Kotlin translates these to static jvm methods, it doesn't use the typed

List<T>

?

In Jetpack Compose, how is navigation supposed to be done?

specifically:

Class 'FilterOptions' is not abstract and does not implement abstract member public abstract fun describeContents(): Int defined in android.os.Parcelable

but in the generated code…

public FilterOptions(@Nullable String keyword) {
      this.keyword = keyword;
   }

   public int describeContents() {
      return 0;
   }

what gives?

how could I run some code after constructor like in Java?

public class CustomView extends View {
    public CustomView(Context context) {
        this(context,null);
    }

    public CustomView(Context context, @Nullable AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public CustomView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        //some custom code
    }
}

I try

init{}

block, but it run before constructor.

class CustomView @JvmOverloads constructor(
    context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : View(context, attrs, defStyleAttr) {
    init {
        // this place is run before super constructor
    }
}

Has anybody use

hilt

on an app that is already/ or about to be published?

How do you navigate from an Android

to a Navigation Component destination (fragment)?

Hi folks, recently published a Redux library using Kotlin 1.4.0, Coroutines, and the Flow API: https://github.com/grant-park/ReduxEngine Would love for anyone to check it out and I would be grateful for any feedback. I'm also always open to discussing MVI for Android apps in general.

For a fragment, what's the difference, if any, between fragment.lifecycleScope.launch() and fragment.viewLifecycleOwner.lifecycleScope.launch() ?

say bye bye to sharedPreferences DATA STORE

How to pass an argument type of Double in Navigation Component?

Hello, can you tell me how can I tint the text hint of my TextInputLayout from theme colors? I was doing tests by I have not found any way.

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar.Bridge">
    <item name="colorPrimary">#2f2f2f</item>
    <item name="colorPrimaryDark">#2f2f2f</item>
    <item name="colorPrimaryVariant">#007038</item>
    <item name="colorOnPrimary">#0D1DB1</item>
    <item name="colorSecondary">#456321</item>
    <item name="colorSecondaryVariant">#965874</item>
    <item name="colorOnSecondary">#741080</item>
    <item name="colorError">#F44336</item>
    <item name="colorOnError">#810000</item>
    <item name="colorSurface">#DFDFDF</item>
    <item name="colorOnSurface">#CFCFCF</item>
    <item name="android:colorBackground">@color/background</item>
    <item name="colorOnBackground">#fff</item>
</style>

that is my theme and the result is this I can't see the hint of the TextInputLayout when it is unselected.

Does updating a plugin in one Android Studio break it for another on Linux? E.g. does updating Flutter plugin in Canary installation break Flutter in the stable version?

When starting on a project whose design is ready what steps should consider before start coding? Architecture of project is important. Use case diagram, class diagram they are useful also. But anyone have any resources or thorough guideline to share about the whole process from the very beginning? Thanks advanced. (Asking from android perspective but should consider ios or obviously web for later)
