Error while adding an Image composable function in Android Studio

June 4, 2023

I am following the android development course on developer.android.com and wile adding the above composable function I am getting the following error:

None of the following functions can be called with the arguments supplied.

Image(ImageBitmap, String?, Modifier = …, Alignment = …, ContentScale = …, Float = …, ColorFilter? = …, FilterQuality = …) defined in androidx.compose.foundation
Image(Painter, String?, Modifier = …, Alignment = …, ContentScale = …, Float = …, ColorFilter? = …) defined in androidx.compose.foundation
Image(ImageVector, String?, Modifier = …, Alignment = …, ContentScale = …, Float = …, ColorFilter? = …) defined in androidx.compose.foundation

According to the course tutorial the error should resolve after including the following import:

import androidx.compose.foundation.Image

This is the the code where i am using the imahge composable:

@Composable
fun GreetingImage(message: String, from: String, modifier: Modifier = Modifier) {
    val image = painterResource(R.drawable.androidparty)
        Image(
            painter = image
        )
}

>Solution :

The Image function has two required parameters, not just one:

@Composable
fun Image(
    painter: Painter,
    contentDescription: String?,
    modifier: Modifier = Modifier,
    alignment: Alignment = Alignment.Center,
    contentScale: ContentScale = ContentScale.Fit,
    alpha: Float = DefaultAlpha,
    colorFilter: ColorFilter? = null
): Unit

So in addition to setting the painter, you also must provide a contentDescription – that’s the string that users with impaired vision will have read to them, since they cannot see what painter you have set:

@Composable
fun GreetingImage(message: String, from: String, modifier: Modifier = Modifier) {
    val image = painterResource(R.drawable.androidparty)
    // Make a String resource in res/values/strings.xml
    val contentDescription = stringResource(R.string.androidparty)
    Image(
        painter = image
      )
}
