在边框前添加填充可以解决你的问题。下面是完整的代码。

@Composable
fun BottomStrip() {
    Row(modifier = Modifier
        .fillMaxWidth()
        .height(70.dp)
        .background(color = colorResource(id = R.color.cgux_background_grey)),
        horizontalArrangement = Arrangement.End, verticalAlignment = Alignment.CenterVertically) {
        Image(
            painter = painterResource(id = R.drawable.cgux_ic_keyboard_16),
            modifier = Modifier
                .width(36.dp)
                .height(36.dp)
                .padding(5.dp)
                .border(BorderStroke(1.dp, colorResource(id = R.color.cgux_primary_500_base)))
                .padding(5.dp)
                .clickable {},
            contentDescription = "Expandable Image",
            colorFilter = ColorFilter.tint( colorResource(id = R.color.cgux_primary_500_base))
        )
    }
}

你可以试试下面这样。

@Composable
fun BottomStrip() {
    Row(
        modifier = Modifier
            .fillMaxWidth()
            .height(70.dp)
            .background(color = Color.Cyan),
        horizontalArrangement = Arrangement.End, verticalAlignment = Alignment.CenterVertically
    ) {
        Image(
            painter = painterResource(id = R.drawable.ic_visa),
            modifier = Modifier
                .padding(5.dp)
                .border(BorderStroke(1.dp, Color.Red))
                .clickable {},
            contentDescription = null
        )
    }
}

在jetpack组合中，修改器的顺序很重要。官方文档
您可以使用此解决方案并在设置图像大小之前添加填充：

@Composable
fun BottomStrip() {
    Row(modifier = Modifier
        .fillMaxWidth()
        .height(70.dp)
        .background(color = colorResource(id = R.color.cgux_background_grey)),
        horizontalArrangement = Arrangement.End, verticalAlignment = Alignment.CenterVertically) {
        Image(
            painter = painterResource(id = R.drawable.cgux_ic_keyboard_16),
            modifier = Modifier
                .padding(5.dp) // padding between Row and Image, you can remove it because you already set size for Image and Row
                .border(BorderStroke(1.dp, colorResource(id = R.color.cgux_primary_500_base)))
                .padding(5.dp) // padding between border and image
                .size(36.dp)
                .clickable {},
            contentDescription = "Expandable Image",
            colorFilter = ColorFilter.tint( colorResource(id = R.color.cgux_primary_500_base))
        )
    }
}
