Download
Gradle
Add the below codes to your root build.gradle
file (not your module build.gradle file).
allprojects {
repositories {
mavenCentral()
}
}
Next, add the below dependency to your module's build.gradle
file.
dependencies {
implementation "io.getstream:avatarview-coil:1.0.7"
}
Note: The
io.getstream.avatarview-coil
dependency includes Coil to load images internally. So if you're using Coil in your project, please make sure your project is using the same Coil version or exclude Coil dependencies to adapt yours.
We highly recommend using AvatarView-Coil to load images. However, if you'd more prefer to use Glide, you can use AvatarView-Glide instead.
SNAPSHOT
See how to import the snapshot
Including the SNAPSHOT
Snapshots of the current development version of AvatarView are available, which track the latest versions.
To import snapshot versions on your project, add the code snippet below on your gradle file.
repositories {
maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' }
}
Next, add the below dependency to your module's build.gradle
file.
dependencies {
implementation "io.getstream:avatarview-coil:1.0.7-SNAPSHOT"
implementation "io.getstream:avatarview-glide:1.0.7-SNAPSHOT"
}
Usage
First, add the following XML namespace inside your XML layout file.
xmlns:app="http://schemas.android.com/apk/res-auto"
AvatarView in XML layout
You can customize AvatarView
in your XML layout by setting attributes.
<io.getstream.avatarview.AvatarView
android:layout_width="110dp"
android:layout_height="110dp"
app:avatarViewBorderColor="@color/yellow"
app:avatarViewBorderWidth="3dp"
app:avatarViewIndicatorBorderColor="@color/white"
app:avatarViewIndicatorBorderSizeCriteria="10"
app:avatarViewIndicatorColor="@color/md_green_100"
app:avatarViewIndicatorEnabled="true"
app:avatarViewIndicatorPosition="bottomRight"
app:avatarViewIndicatorSizeCriteria="9"
app:avatarViewInitialsTextStyle="bold"
app:avatarViewShape="circle" />
Loading Single Image
You can load an image on your AvatarView
by using the loadImage
method as in the example below:
avatarView.loadImage(data)
The default supported data types are String
, Uri
, HttpUrl
, File
, DrawableRes
, Drawable
, and Bitmap
.
You can also set a place holder and request listeners as in the example below:
avatarView.loadImage(
data = data,
placeholder = drawable,
onStart = {
// started requesting an image
},
onComplete = {
// completed requesting an image
}
)
Loading Images with Fractional Style
AvatarView
supports loading up to four images with the fractional style as in the example below:
avatarView.loadImage(
data = listof(url1, url2, url3, url4)
)
We can set the maximum section size of the avatar when we load multiple images by using the avatarViewMaxSectionSize
attribute as in the exmample below:
app:avatarViewMaxSectionSize="4"
The default value is 4, and you can set the fractional formats to your taste.
Loading Placeholder
We can set a placeholder to show a placeholder during loading an image as in the example below:
app:avatarViewPlaceholder="@drawable/stream"
Or we can set a drawable manually on the AvatarView
.
avatarView.placeholder = drawable
Error Placeholder
We can set an error placeholder to show a placeholder when the request failed as in the example below:
app:avatarViewErrorPlaceholder="@drawable/stream"
Or we can set a drawable manually on the AvatarView
.
avatarView.errorPlaceholder = drawable
Custom ImageRequest
You can customize ImageRequest and provide information to load an image as in the example below:
avatarView.loadImage(
data = data
) {
crossfade(true)
crossfade(300)
transformations(CircleCropTransformation())
lifecycle(this@MainActivity)
}
Border
You can customize border relevant attributes as in the example below:
<io.getstream.avatarview.AvatarView
android:layout_width="110dp"
android:layout_height="110dp"
app:avatarViewBorderColor="@color/white"
app:avatarViewBorderWidth="3dp" />
Also, you can make a gradient for the border with an avatarViewIndicatorBorderColorArray
attribute. First, declare an array of color in you colors.xml file as in the example below:
colors.xml
<array name="rainbow">
<item>@color/red</item>
<item>@color/orange</item>
<item>@color/yellow</item>
<item>@color/chartreuse</item>
<item>@color/green</item>
</array>
Next, apply the color array with the avatarViewBorderColorArray
attribute instread of the avatarViewBorderColor
as in the below example:
<io.getstream.avatarview.AvatarView
android:layout_width="110dp"
android:layout_height="110dp"
app:avatarViewBorderColorArray="@color/white"
app:avatarViewBorderWidth="3dp" />
Shape
AvatarView supports two shapes; circle and rounded rect. You can customize the shapes as in the example below:
Circle
You can set the shape as a circle by setting the avatarViewShape
attribute to circle
.
<io.getstream.avatarview.AvatarView
android:layout_width="110dp"
android:layout_height="110dp"
app:avatarViewShape="circle" />
Rounded Rect
You can set the shape as a rounded rect by setting the avatarViewShape
attribute to rounded_rect
. Also, you can customize a radius of the border with an avatarViewBorderRadius
attribute.
<io.getstream.avatarview.AvatarView
android:layout_width="110dp"
android:layout_height="110dp"
app:avatarViewShape="rounded_rect"
app:avatarViewBorderRadius="21dp"
/>
Indicator
AvatarView supports drawing an indicator, which can be used for presenting a user online status or badges. You can enable it by giving true for an avatarViewIndicatorEnabled
attribute as in the example below:
<io.getstream.avatarview.AvatarView
android:layout_width="110dp"
android:layout_height="110dp"
app:avatarViewIndicatorEnabled="true"
app:avatarViewIndicatorColor="@color/green"
app:avatarViewIndicatorBorderColor="@color/white"
app:avatarViewIndicatorSizeCriteria="9"
app:avatarViewIndicatorBorderSizeCriteria="10"
app:avatarViewIndicatorPosition="bottomRight" />
As you can see above, you can customize the color of the indicator and border of the indicator, size criteria, and position. Also, you can customize the whole indicator with your custom drawable resource:
<io.getstream.avatarview.AvatarView
android:layout_width="110dp"
android:layout_height="110dp"
app:avatarViewIndicatorDrawable="@drawable/stream" />
Initials
AvatarView
supports drawing initials. You can draw and customize initials instead of loading an image over the AvatarView
as in the example below:
<io.getstream.avatarview.AvatarView
android:layout_width="110dp"
android:layout_height="110dp"
app:avatarViewInitials="AB"
app:avatarViewInitialsBackgroundColor="@color/skyBlue"
app:avatarViewInitialsTextColor="@color/white"
app:avatarViewInitialsTextSize="21sp"
app:avatarViewInitialsTextSizeRatio="0.33"
app:avatarViewInitialsTextStyle="bold" />
AvatarCoil
The io.getstream.avatarview-coil
dependency supports customizing the internal Coil that is called AvatarCoil
.
Custom ImageLoader
You can load images with your custom ImageLoader
to load AvatarView
by setting an ImageLoaderFactory
on the AvatarCoil
. Then all AvatarView
will be loaded by the provided ImageLoader
as in example the below:
AvatarCoil.setImageLoader(
AvatarImageLoaderFactory(context) {
crossfade(true)
crossfade(400)
okHttpClient {
OkHttpClient.Builder()
.cache(CoilUtils.createDefaultCache(context))
.build()
}
}
)
Custom AvatarBitmapFactory
Loading custom Avatar bitmaps
Avatar bitmaps are created by the internal bitmap factory called AvatarBitmapFactory
. However, you can override the image loading methods and provide your own bitmap loader like the example below:
Note: The
loadAvatarBitmapBlocking
method takes precedence over this one if both are implemented.
AvatarCoil.setAvatarBitmapFactory(
object : AvatarBitmapFactory(context) {
override suspend fun loadAvatarBitmap(data: Any?): Bitmap? {
return withContext(Dispatchers.IO) {
val imageResult = context.imageLoader.execute(
ImageRequest.Builder(context)
.headers(AvatarCoil.imageHeadersProvider.getImageRequestHeaders().toHeaders())
.data(data)
.build()
)
(imageResult.drawable as? BitmapDrawable)?.bitmap
}
}
}
)
If you don't use coroutines, you can override loadAvatarBitmapBlocking
method instead.
AvatarCoil.setAvatarBitmapFactory(
object : AvatarBitmapFactory(context) {
override fun loadAvatarBitmapBlocking(): Bitmap? {
return // return your loaded Bitmap
}
}
)
Loading custom Avatar placeholder bitmaps
Basically, you can draw your placeholder drawable by setting the placeholder
property on the AvatarView
. However, you can provide your own bitmap loader by overriding the loadAvatarPlaceholderBitmap
method like the example below:
Note: The
loadAvatarPlaceholderBitmap
will be executed if the previous image request failed. And theloadAvatarPlaceholderBitmapBlocking
method takes precedence over this one if both are implemented.
AvatarCoil.setAvatarBitmapFactory(
object : AvatarBitmapFactory(context) {
override fun loadAvatarPlaceholderBitmap(): Bitmap? {
return // return your loaded placeholder Bitmap
}
}
)
If you don't use coroutines, you can override loadAvatarPlaceholderBitmapBlocking
method instead like the example below:
AvatarCoil.setAvatarBitmapFactory(
object : AvatarBitmapFactory(context) {
override fun loadAvatarPlaceholderBitmapBlocking(): Bitmap? {
return // return your loaded placeholder Bitmap
}
}
)
Custom ImageHeadersProvider
If you're using your own CDN, you can set the imageHeadersProvider
on AvatarCoil
to load image data with your own header as in the example below:
AvatarCoil.imageHeadersProvider = yourImageHeadersProvider
AvatarView with Glide
We highly recommend using AvatarView-Coil to load images if possible. However, you can also use Glide instead.
π Check out AvatarView-Glide.
Stream Integration
AvatarView supports integrating features with Stream Chat SDK for Android. First, You can simply integrate with Stream Chat SDK by adding the dependency below:
dependencies {
implementation "io.getstream:avatarview-stream-integration:$avatarview_version"
}
Next, you should set the StreamAvatarBitmapFactory
on the AvatarCoil
as in the below:
AvatarCoil.setAvatarBitmapFactory(StreamAvatarBitmapFactory(context))
Basically, it will load the image
extra data of the User
. But if there's no valid image data, the initials from the name
will be loaded.
Then you can set your User
model to the AvatarView
as in the example below:
val currentUser = ChatClient.instance().getCurrentUser()
avatarView.setUserData(currentUser)
Also, you can set your Channel
model to the AvatarView
as in the example below:
avatarView.setChannel(channel)
The channel image will be loaded. But if there is no valid channel image, an image composed of members will be loaded.
