EventListener

EventListener is small library and is used for communication between classes like broadcaste signals No Need to maintain listener reference. It auto work with app lifecycle.

Prerequisites

  • Android 14

Installing

Step 1:- Add it in your root build.gradle at the end of repositories:

allprojects {
  repositories {
   ...
   maven { url 'https://jitpack.io' }
  }
 }
  

Step 2:- Add the dependency:


 dependencies {
         implementation 'com.github.prabhat1707:EventListener:1.0'
 }
 
  

Usage

SendData to Register Listener:-


EventListener.getInstance().post(modelClass, "From Fragment");

Rec callback of the sendData :

  • if you want to rec your post modelclass as well as Tag in callback then pass ModelClass Type in DataWrapper
implement Updatable<DataWrapper<ObjectClass>> :

@Override
    public void EventListenerCallback(DataWrappe<ModelClass> objectDataWrapper) {
        Toast.makeText(this, objectDataWrapper.getTag(), Toast.LENGTH_SHORT).show();
        text.setText(objectDataWrapper.getObject().getTest());
    }
    
    //  objectDataWrapper.getObject return your modelClass

  • default is
implements Updatable<DataWrapper>

 @Override
    public void EventListenerCallback(DataWrapper objectDataWrapper) {
        Toast.makeText(this, objectDataWrapper.getTag(), Toast.LENGTH_SHORT).show();
      
    }
    
  • register or unregister the callback according to your logic for ex-:
@Override
    protected void onResume() {
        super.onResume();
        EventListener.getInstance().registerListener(this);
    }
    
@Override
    protected void onDestroy() {
        super.onDestroy();
        EventListener.getInstance().unregisterListener(this);
    }

Contructor types:

  1. EventListener.getInstance().post("From Fragment"); // only Tag

  2. EventListener.getInstance().post(); // without Tag and data

  3. EventListener.getInstance().post(modelClass, "From Fragment"); // with data also
