Moxy

Moxy is a library that helps to use MVP pattern when you do the Android Application. Without problems of lifecycle and boilerplate code!

The main idea of using Moxy:

Description

See what's happening here in the wiki.

Capabilities

Moxy has a few killer features in other ways:

  • Presenter stay alive when Activity recreated(it simplify work with multithreading)
  • Automatically restore all that user see when Activity recreated(including dynamic content is added)
  • Capability to changes of many Views from one Presenter

Sample

View interface

public interface HelloWorldView extends MvpView {
	void showMessage(int message);
}

Presenter

@InjectViewState
public class HelloWorldPresenter extends MvpPresenter<HelloWorldView> {
	public HelloWorldPresenter() {
		getViewState().showMessage(R.string.hello_world);
	}
}

View implementation

public class HelloWorldActivity extends MvpAppCompatActivity implements HelloWorldView {

	@InjectPresenter
	HelloWorldPresenter mHelloWorldPresenter;

	private TextView mHelloWorldTextView;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_hello_world);

		mHelloWorldTextView = ((TextView) findViewById(R.id.activity_hello_world_text_view_message));
	}

	@Override
	public void showMessage(int message) {
		mHelloWorldTextView.setText(message);
	}
}

Here you can see "Github" sample application.

Android studio templates

In order to avoid boilerplate code creating for binding activity, fragments and its presentation part, we propose to use Android Studio templates for Moxy.

Integration

Base modules integration:

dependencies {
  ...
  compile 'com.arello-mobile:moxy:1.5.5'
  annotationProcessor 'com.arello-mobile:moxy-compiler:1.5.5'
}

For additional base view classes MvpActivity and MvpFragment add this:

dependencies {
  ...
  compile 'com.arello-mobile:moxy-android:1.5.5'
}

If you are planning to use AppCompat, then you can use MvpAppCompatActivity and MvpAppCompatFragment. Then add this:

dependencies {
  ...
  compile 'com.arello-mobile:moxy-app-compat:1.5.5'
  compile 'com.android.support:appcompat-v7:$support_version'
}

AndroidX module integration

If you use AndroidX, use MvpAppCompatActivity and MvpAppCompatFragment add this (thanks to @jordan1997):

implementation 'tech.schoolhelper:moxy-x-androidx:1.7.0'

AndroidX(Google material) module integration

If you use google material, use MvpBottomSheetDialogFragment add this (thanks to @jordan1997):

implementation 'tech.schoolhelper:moxy-x-material:1.7.0'

Note: @jordan1997 creates fork of Moxy — feel free to use it fully (instead of use only this module dependency) on your opinion.

Kotlin

If you are using kotlin, use kapt instead of provided/apt dependency type:

apply plugin: 'kotlin-kapt'

dependencies {
  ...
  kapt 'com.arello-mobile:moxy-compiler:1.5.5'
}

ProGuard

Moxy is completely without reflection! No special ProGuard rules required.
