ToggleableButton
ToggleableButton is a library that allows you to create a button similar to:

Basic Usage
Copy all the files above

Attributes
The attributes that can be used to configure the button's behavior and appearance are:

          <com.example.app.ToggleableButton
            app:icon="@drawable/ic_favorite_border"
            app:active_icon="@drawable/ic_favorite_active"
            app:active="true"
            app:count="5"/>

Button State
To set the initial active state of the button you simply use the setActive() functionality via XML or Java. This will show the button in the click/unclicked state(depending on the active state) with the drawable that you selected.

XML
app:active="true"

Java
button.setActive(true)

You can also set the count of the button using the setCountValue() functionality via XML or Java:

XML
app:count="3"

Java
button.setCountValue(5)

OR
To increment the count use:
button.incrementCount()

To decrement the count use:
button.decrementCount()

Button Event Listener
To make the button toggleable and listen for click/unclick events:

  button.enableClickToggle(true);
  button.setOnClickToggleListener(new OnClickToggleListener {
        
       @Override
        public void onClicked(){
               // implement code
        }

        @Override
        public void onUnclicked(){
               // implement code
        }
    });

You can also set the button to behave like a normal button, i.e. listen for only click events. To make the button behave like a normal button:

  button.enableClickToggle(false);
  button.setOnClickListener(new OnClickListener {
         @Override
         public void onClick() {
             //implement code
         }
    });

Example
To create this button:

XML

    <com.example.app.ToggleableButton`
            android:id="@+id/item_post_ib_like"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:icon="@drawable/icons8_heart_inactive"
            app:active_icon="@drawable/icons8_love_active"
            android:background="@android:color/transparent"
            android:layout_marginRight="7dp"/>

        button.enableClickToggle(true);
        button.setOnClickToggleListener(new ToggleableButton.OnClickToggleListener() {
               @Override
               public void onClicked() {
                   button.incrementCount();
               }

               @Override
               public void onUnclicked() {
                   button.decrementCount();
               }
           });
