I have a simple activity which I am using to convert a composeView to Bitmap.
However when I run the below myBitmap is blank and does not show the "Hello" text composable.
How can I make the below convert composeView to Bitmap?
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
val widthPx = 200
val heightPx = 120
val composeView = ComposeView(applicationContext)
composeView.setContent {
Text(
text = "Hello",
color = Color.Black,
fontSize = 14.sp,
modifier = Modifier
.wrapContentSize()
.background(Color.Green)
)
}
val myBitmap: Bitmap = Bitmap.createBitmap(widthPx,heightPx,Bitmap.Config.ARGB_8888)
val myCanvas = Canvas(myBitmap)
composeView.draw(myCanvas)
val result = myBitmap /*<--- result is blank bitmap*/
}
}
