This library brings easy-to-use composable which can fetch and display images from external sources, such as network, using the Glide image loading library.
The primary API is via the GlideImage()
functions. There are a number of function versions available.
The simplest usage is like so:
GlideImage(
data = "https://picsum.photos/300/300",
contentDescription = "My content description",
)
This loads the data
passed in with Glide, and then displays the resulting image using the standard Image
composable.
You can also customize the Glide RequestBuilder
through the requestBuilder
parameter. This allows usage of things like (but not limited to) transformations:
GlideImage(
data = "https://picsum.photos/300/300",
contentDescription = "My content description",
requestBuilder = {
val options = RequestOptions()
options.centerCrop()
apply(options)
},
)
It also provides optional content 'slots', allowing you to provide custom content to be displayed when the request is loading, and/or if the image request failed:
GlideImage(
data = "https://picsum.photos/300/300",
contentDescription = "My content description",
loading = {
Box(Modifier.matchParentSize()) {
CircularProgressIndicator(Modifier.align(Alignment.Center))
}
},
error = {
Image(asset = imageResource(R.drawable.ic_error))
}
)
This library has built-in support for animating loaded images in, using a fade-in animation.
There are two ways to enable the animation:
A fadeIn: Boolean
parameter has been added to GlideImage
(default: false
). When enabled, a default fade-in animation will be used when the image is successfully loaded:
GlideImage(
data = "https://picsum.photos/300/300",
contentDescription = "My content description",
fadeIn = true
)
If you need more control over the animation, or you want to provide custom layout for the loaded image, you can use the content
composable version of GlideImage
:
GlideImage(
data = "https://picsum.photos/300/300",
) { imageState ->
when (imageState) {
is ImageLoadState.Success -> {
MaterialLoadingImage(
result = imageState,
contentDescription = "My content description",
fadeInEnabled = true,
fadeInDurationMs = 600,
)
}
is ImageLoadState.Error -> /* TODO */
ImageLoadState.Loading -> /* TODO */
ImageLoadState.Empty -> /* TODO */
}
}
Accompanist Glide supports GIFs through Glide's own GIF support. There's nothing you need to do, it should just work.
If you wish to provide a default RequestManager
to use across all of your GlideImage
calls, we provide the LocalRequestManager
composition local.
You can use it like so:
val requestManager = Glide.with(...)
// customize the RequestManager as needed
.build()
CompositionLocalProvider(LocalRequestManager provides requestManager) {
// This will automatically use the value of LocalRequestManager
GlideImage(
data = ...
)
}
