artcrespo / HomeActivity.kt

Created February 5, 2019 20:55 — forked from antoniolg/HomeActivity.kt

Snackbar extensions on Kotlin, to create a useful small DSL.

	class HomeActivity : AppCompatActivity() {

	override fun onCreate(savedInstanceState: Bundle?) {
	super.onCreate(savedInstanceState)
	setContentView(R.layout.activity_home)
	setSupportActionBar(toolbar)

	fab.setOnClickListener {
	it.snack("Snack message") {
	action("Action") { toast("Action clicked") }

artcrespo / SharedPreferenceLiveData.kt

Created June 13, 2018 01:07 — forked from rharter/SharedPreferenceLiveData.kt

Creates LiveData objects that observe a value in SharedPreferences while they have active listeners.

	import android.arch.lifecycle.LiveData
	import android.content.SharedPreferences

	abstract class SharedPreferenceLiveData<T>(val sharedPrefs: SharedPreferences,
	val key: String,
	val defValue: T) : LiveData<T>() {

	private val preferenceChangeListener = SharedPreferences.OnSharedPreferenceChangeListener { sharedPreferences, key ->
	if (key == this.key) {
	value = getValueFromPreferences(key, defValue)
