Library for android. Helping you to handle data result from remote data source or local data source.
Add it in your root build.gradle at the end of repositories:
allProjects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}Add the dependency:
dependencies {
implementation 'com.github.fajaragungpramana:result-helper:0.0.2'
}First step. You can create function return ResultHelper<TYPE> to handle your data result. For example in my MainRepository.kt
class MainRepository {
fun getPersonName(): ResultHelper<String> = connection {
val name = "Fajar Agung Pramana"
if (name.isNotEmpty())
ResultHelper.OnSuccess(name)
else
ResultHelper.OnFailure()
}
}connection {} is wrapper function to handle result when your logic get an exception. you can handle the exception result in ResultHelper.OnError(Throwable)
And in your Activity or Fragment or ViewModel or another class. You can call the function like code bellow. For example MainActivity.kt
class MainActivity : AppCompatActivity() {
private lateinit var mMainRepository: MainRepository
private val mPersonName by lazy { findViewById<TextView>(R.id.tv_name) }
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
if (!::mMainRepository.isInitialized) mMainRepository = MainRepository()
mMainRepository.getPersonName().onResultListener(
onSuccess = { data, code, message ->
// TODO: Do something magic here when get result success.
mPersonName.text = data
},
onFailure = { data, code, message ->
// TODO: Do something magic here when get result failure.
},
onError = { throwable ->
// TODO: Do something magic here when get result error.
}
)
}
}
