Crouton
Context sensitive notifications for Android
DEPRECATION NOTICE
This library has passed it's prime and is now considered deprecated.
With the Android Design Support Library introducing Snackbar developers get a well crafted pattern to use for context aware notification of users.
I won't do any active development for Crouton any more. But I still do accept pull requests that fix bugs.
So long, and thanks for all the forks.
Overview
Crouton is a class that can be used by Android developers that feel the need for an alternative to the Context insensitive Toast.
A Crouton will be displayed at the position the developer decides. Standard will be the top of an application window. You can line up multiple Croutons for display, that will be shown one after another.
You can check some features in the Crouton Demo.
If you're already using Crouton and just want to download the latest version of the library, follow this link.
Releases / Changelog
Current version: 1.8.5
Usage
The API is kept as simple as the Toast API:
Create a Crouton for any CharSequence:
Crouton.makeText(Activity, CharSequence, Style).show();
Create a Crouton with a String from your application's resources:
Crouton.makeText(Activity, int, Style).show();
Further you can attach a Crouton to any ViewGroup like this:
Crouton.makeText(Activity, int, Style, int).show();
Crouton.makeText(Activity, int, Style, ViewGroup).show();
Also Crouton.show(...) methods are available for convenient fire and forget display of Croutons.
If you would like a more graphical introduction to Crouton check out this presentation.
##Important!
In your Activity.onDestroy() make sure to call
Crouton.cancelAllCroutons();
to cancel cancel all scheduled Croutons.
This is a workaround and further description is available in issue #24.
Basic Examples
Currently you can use the three different Style attributes displayed below out of the box:
Extension and Modification
The whole design of a Crouton is defined by Style.
You can use one of the styles Crouton ships with: Style.ALERT, Style.CONFIRM and Style.INFO. Or you can create your own Style.
In general you can modify
- display duration
- dimension settings
- options for the text to display
- custom Views
- appearance & disappearance Animation
- displayed Image
Since Style is the general entry point for tweaking Croutons, go and see for yourself what can be done with it.
Building
Gradle
From maven central
Add maven central to your build.gradle:
buildscript {
repositories {
mavenCentral()
}
}
repositories {
mavenCentral()
}
Then declare Crouton within your dependencies:
dependencies {
...
compile('de.keyboardsurfer.android.widget:crouton:1.8.5@aar') {
// exclusion is not necessary, but generally a good idea.
exclude group: 'com.google.android', module: 'support-v4'
}
...
}
Maven
From maven central
To use crouton within your maven build simply add
<dependency>
<artifactId>crouton</artifactId>
<version>${crouton.version}</version>
<groupId>de.keyboardsurfer.android.widget</groupId>
</dependency>
to your pom.xml
If you also want the sources or javadoc add the respective classifier
<classifier>sources</classifier>
or
<classifier>javadoc</classifier>
to the dependency.
If you are referencing a newer version of the Android Support Library in your application, you might want to exclude Crouton's dependency like this:
<dependency>
<artifactId>crouton</artifactId>
<version>${crouton.version}</version>
<groupId>de.keyboardsurfer.android.widget</groupId>
<exclusions>
<exclusion>
<groupId>com.android.support</groupId>
<artifactId>support-v4</artifactId>
</exclusion>
</exclusions>
</dependency>
DIY
The build requires Gradle. Operations are very simple:
- install gradle
gradle assemblebuilds all artifactsgradle jarbuilds the jar
After putting Crouton in a repository you can add it as dependency.
compile('de.keyboardsurfer.android.widget:crouton:1.8.5@aar') {
exclude group: 'com.google.android', module: 'support-v4'
}
###Building and Signing
In order to build and sign Crouton locally you'll need to rename gradle.properties.sample to gradle.properties.
