Conductor

A small, yet full-featured framework that allows building View-based Android applications. Conductor provides a light-weight wrapper around standard Android Views that does just about everything you'd want:

Conductor
🎉 Easy integration
☝? Single Activity apps without using Fragments
♻? Simple but powerful lifecycle management
🚋 Navigation and backstack handling
🔀 Beautiful transitions between views
💾 State persistence
☎? Callbacks for onActivityResult, onRequestPermissionsResult, etc
🏤 MVP / MVVM / VIPER / MVC ready

Conductor is architecture-agnostic and does not try to force any design decisions on the developer. We here at BlueLine Labs tend to use either MVP or MVVM, but it would work equally well with standard MVC or whatever else you want to throw at it.

Installation

compile 'com.bluelinelabs:conductor:2.1.4'  // If you want the components that go along with // Android's support libraries (currently just a PagerAdapter): compile 'com.bluelinelabs:conductor-support:2.1.4'  // If you want RxJava lifecycle support: compile 'com.bluelinelabs:conductor-rxlifecycle:2.1.4'  // If you want RxJava2 lifecycle support: compile 'com.bluelinelabs:conductor-rxlifecycle2:2.1.4'  // If you want RxJava2 Autodispose support: compile 'com.bluelinelabs:conductor-autodispose:2.1.4'  // If you want Controllers that are Lifecycle-aware (architecture components): compile 'com.bluelinelabs:conductor-archlifecycle:0.1.1'

SNAPSHOT

Just use 2.1.5-SNAPSHOT as your version number in any of the dependencies above and add the url to the snapshot repository:

allprojects {

repositories {

  maven {
 url "https://oss.sonatype.org/content/repositories/snapshots/" 
}

}
 
}

Components to Know

Conductor Components
Controller The Controller is the View wrapper that will give you all of your lifecycle management features. Think of it as a lighter-weight and more predictable Fragment alternative with an easier to manage lifecycle.
Router A Router implements navigation and backstack handling for Controllers. Router objects are attached to Activity/containing ViewGroup pairs. Routers do not directly render or push Views to the container ViewGroup, but instead defer this responsibility to the ControllerChangeHandler specified in a given transaction.
ControllerChangeHandler ControllerChangeHandlers are responsible for swapping the View for one Controller to the View of another. They can be useful for performing animations and transitions between Controllers. Several default ControllerChangeHandlers are included.
ControllerTransaction Transactions are used to define data about adding Controllers. RouterControllerTransactions are used to push a Controller to a Router with specified ControllerChangeHandlers, while ChildControllerTransactions are used to add child Controllers.

Getting Started

Minimal Activity implementation

public class MainActivity extends Activity {

private Router router;

@Override
  protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

 setContentView(R.layout.activity_main);

 ViewGroup container = (ViewGroup)findViewById(R.id.controller_container);

 router = Conductor.attachRouter(this, container, savedInstanceState);

if (!router.hasRootController()) {

 router.setRoot(RouterTransaction.with(new HomeController()));

}

  
}

@Override
  public void onBackPressed() {

if (!router.handleBack()) {

 super.onBackPressed();

}

  
}
  
}

Minimal Controller implementation

public class HomeController extends Controller {

@Override
  protected View onCreateView(@NonNull LayoutInflater inflater, @NonNull ViewGroup container) {

View view = inflater.inflate(R.layout.controller_home, container, false);

((TextView)view.findViewById(R.id.tv_title)).setText("Hello World");

return view;
  
}
  
}

Sample Project

Controller Lifecycle

The lifecycle of a Controller is significantly simpler to understand than that of a Fragment. A lifecycle diagram is shown below:

Advanced Topics

Retain View Modes

setRetainViewMode can be called on a Controller with one of two values: RELEASE_DETACH, which will release the Controller's view as soon as it is detached from the screen (saves memory), or RETAIN_DETACH, which will ensure that a Controller holds on to its view, even if it's not currently shown on the screen (good for views that are expensive to re-create).

Custom Change Handlers

ControllerChangeHandler can be subclassed in order to perform different functions when changing between two Controllers. Two convenience ControllerChangeHandler subclasses are included to cover most basic needs: AnimatorChangeHandler, which will use an Animator object to transition between two views, and TransitionChangeHandler, which will use Lollipop's Transition framework for transitioning between views.

Child Routers & Controllers

getChildRouter can be called on a Controller in order to get a nested Router into which child Controllers can be pushed. This enables creating advanced layouts, such as Master/Detail.

RxJava Lifecycle

If the RxLifecycle dependency has been added, there is an RxController available that can be used along with the standard RxLifecycle library. There is also a ControllerLifecycleProvider available if you do not wish to use this subclass.

Android Ruler number picker.

Customisable menu that could have from 1 to 10 (and more) buttons. Colors, radius, pictograms - everything can be changed. It suits more for center oriented interfaces and screens. For example by tapping on profile avatar you can open additional functions like Edit, Change Photo etc.

This is a more modified version of EditText. in conventional EditText in android we get the default functionalities, but one of the most important functionality is missing in the default EditText. As we know, we must have to validate the data before taking it as an input in EditText, so this functionality is provided in this mod.

ReactiveFB provides an API that bridges the reactive world of RxJava 2.0 with the callback-style of Facebook-SDK. The aim of the library is to :

  • make the use of the facebook api easy and less boilerplate.
  • expose the facebook api methods to the possibilities of the reactive world like transformations, filtering, composition.

Material Animations practice.

ActivitySwitcher is based on the Activity view operation management library, you can achieve any jump between Activity, close any Activity and end applications and other functions.
