# compose

Can someone suggest any good references for converting composable to android views, official documentation is pretty basic. I want to explore the best approaches to do the same .

@Composable
fun CustomTextViewCompose(
    customText: String
) {
    Text(text = customText)
}

--------------------------------

class CustomTextView(
    context: Context,
    attrs: AttributeSet? = null,
    defStyle: Int = 0
) : AbstractComposeView(context, attrs, defStyle) {

    var textString by mutableStateOf("")

    @Composable
    override fun Content() {
        CustomTextViewCompose(customText = textString)
    }
}

This is a very pretty basic sample , when it comes to button and all you may have to update the text and do other things to , how to handle those scenarious?

You've got the idea. 🙂 Snapshot state backed view properties for anything you would pass as a parameter to the composable

[wintersoldier]

But is there a way to make these state backed properties as mandatory .
For ex

<app.textview.CustomTextView-->
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
android:id="@+id/tvCustom"/>

binding.tvCustom.apply{
//here how can I make this property as mandatory //,if I didn’t pass textString how
}.

@ildar.i [Android], Sorry to tag you , but would like to know if you will be able to help here.

I dont understand the question. Can you reformulate?

no view properties are mandatory in the way composable function parameters are mandatory. The best you'll be able to do is make your state-backed properties nullable and null-check them during composition. If you wanted you could do something like

val currentTextString = textString
if (currentTextString == null) {
  Text("textString wasn't set!", Modifier.background(Color.Red), style = TextStyle(color = Color.Yellow))
} else { ...
