LiveData-CombineUtil-Java contains helper functions for LiveData, to combine their latest emissions.
import static com.zhuinden.livedatacombineutiljava.LiveDataCombineUtil.*;
combine(liveData1, liveData2, liveData3, (t1, t2, t3) -> {
// map to something
}).observe(viewLifecycleOwner, (mapped) -> {
// do something with mapped values
});
It's useful when you want to combine multiple reactive streams together and get a combined object of the latest values.
In order to use LiveData-CombineUtil-Java, you need to add jitpack
to your project root build.gradle.kts
(or build.gradle
):
// build.gradle.kts
allprojects {
repositories {
// ...
maven { setUrl("https://jitpack.io") }
}
// ...
}
or
// build.gradle
allprojects {
repositories {
// ...
maven { url "https://jitpack.io" }
}
// ...
}
In newer projects, you need to also update the settings.gradle
file's dependencyResolutionManagement
block:
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven { url 'https://jitpack.io' } // <--
jcenter() // Warning: this repository is going to shut down soon
}
}
and then, add the dependency to your module's build.gradle.kts
(or build.gradle
):
// build.gradle.kts
implementation("com.github.Zhuinden:livedata-combineutil-java:1.0.0")
or
// build.gradle
implementation 'com.github.Zhuinden:livedata-combineutil-java:1.0.0'
