ErrorView

A custom view that displays an image, a title, and a subtitle. It can be used for various purposes like displaying errors, empty states, or just messages with images.

Download

implementation 'tr.xip.errorview:library:4.0.0'

Note: You might have to add jcenter() to your repositories.

Pre-3.0 versions were com.github.xiprox.errorview:library:x.y.z.

If you're migrating from v2, you may find the changelog in the releases page helpful.

Usage

Image

setImage(int res)
setImage(Drawable)
setImage(Bitmap)

setImageTint(int color)

setImageVisible(boolean)

setImageSize(int width) // The ImageView adjusts its height to preserve aspect ratio.

.isImageVisible
app:ev_image="@drawable/,,,"
app:ev_imageTint="@color/..."
app:ev_imageVisible="boolean"
app:ev_imageSize="123dp"

Title

setTitle(String)
setTitle(int res)
setTitleColor(int color)
setTitleVisible(boolean)
.title
.isTitleVisible
app:ev_title="@string/..."
app:ev_titleColor="@color/..."
app:ev_titleVisible="boolean"

Subtitle

setSubtitle(String)
setSubtitle(int res)
setSubtitleColor(int color)
setSubtitleVisible(boolean visible)
.subtitle
.isSubtitleVisible
app:ev_subtitle="@string/..."
app:ev_subtitleColor="@color/..."
app:ev_subtitleVisible="boolean"

Retry button

setRetryText(String)
setRetryText(int res)
setRetryColor(int color)
setRetryVisible(boolean)
.retryText
.isRetryVisible
app:ev_retryText="@string/..."
app:ev_retryBackground="@drawable/..."
app:ev_retryColor="@color/..."
app:ev_retryVisible="boolean"

Retry listener

setRetryListener(RetryListener)

Builder pattern

All set methods return ErrorView, so you can chain them like such:

errorView.setImage(image).setTitle(e.title).setSubtitle(e.message).setRetryVisible(false)

Theming

You can theme ErrorView app-wide:

<style name="AppTheme" parent="Theme.AppCompat.DayNight.DarkActionBar">
    ...
    <item name="ev_style">@style/MyErrorView</item>
</style>
 
<style name="MyErrorView">
    <item name="ev_retryText">@string/error_retry</item>
    <item name="ev_image">@drawable/sadface</item>
</style>

You can also apply themes to specific ErrorViews:

<tr.xip.errorview.ErrorView
    android:id="@+id/specialErrorView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/MySpecialErrorView"/>
<style name="MySpecialErrorView">
    <item name="ev_imageSize">120dp</item>
    <item name="ev_retryColor">@color/apptheme_accent>>
</style>

And yes, ErrorView supports AppCompat.DayNight out-of-the-box. In fact the above style snippet is from the sample app.

Further customization

If you are looking for further customization, you can always do something like the following, albeit a bit hacky:

val image = errorView.findViewById(R.id.ev_image)
val title = errorView.findViewById(R.id.ev_title)
val subtitle = errorView.findViewById(R.id.ev_subtitle)
val retryButton = errorView.findViewById(R.id.ev_retry)

These view ids will not be changed unless there is a major version increment (e.g. 4.0.0 -> 5.0.0).
