Resources

SwitchPreferenceCompat allows to use SwitchCompat as preference.

Android AlertDialog that only shows once for a given string.

This is a subclass of AlertDialog with all its features supported. The only difference is that a key is provided in its initialization, which is used to check the default SharedPreferences and save itself once shown.

Use cases:

  • Show your app's recent updates prompt just once per version name.
  • Show a "rate now" prompt just once.
  • Quickly create a randomly shown message without worrying about the preferences.

Tree view implementation for Android.

A demonstration of handling Activities and Fragments using Dagger dependency injection framework

The real benefit here is that you create an object graph only when you need it. This contributes to keeping the memory footprint of your app as low as possible.

TitledEditText allows to write a large font sized title with a content like done in SimpleNote.

MovingButton is an Android button which moves in eight direction.
