Set Drawable instance to Image in Jetpack Compose

Question

In Jetpack Compose, who can tell me is there a way to assign a Drawable Object to the Image compose view?

I took the apps installed on an Android device. I get an icon with the type that is Drawable and I want to use it in Image

val icon: Drawable = packageInfor.applicationInfo.loadIcon(packageManager)

I found there are 3 functions that can assign images

• From Painter (IdRes)
• From ImageBitmap
• From ImageVector

From all that I don't know how to assign a Drawable instance.

Answer 1

After all, I found a simple solution with Accompanist. Thanks to @Sinner of the System for suggesting to me.

Adding this dependency to the app gradle.

implementation "com.google.accompanist:accompanist-drawablepainter:<version>" //0.16.0

Using:

Image(
    painter = rememberDrawablePainter(drawable = drawable),
    contentDescription = "content description",
)

Edit: You should definitely use the accompanist library as recommended in the Wilson Tran answer. Since it provides support for several kinds of drawables.

If you're not using the accompanist library, you can do the following...

ContextCompat.getDrawable(LocalContext.current, R.mipmap.ic_launcher)?.let {
    Image(bitmap = it.toBitmap().asImageBitmap(), contentDescription = null)
}

You can set the drawable size in toBitmap function if you want...

If you're using the Coil library, rememberImagePainter will accept an Any? as its data argument, which includes support for Drawable instances. I'm using this as an all-in-one solution for my images rather than importing Accompanist.

Image(
    painter = rememberImagePainter(data = myDrawableInstance)
)

You can do like that

 val backgroundImage = painterResource(R.drawable.your_image)

and then pass this to your image like that

 Image(painter = backgroundImage, contentDescription = null)

That will work.
