How to pass values from RecycleAdapter to MainActivity or Other Activities

Using  Local Broadcast.

In Adapter:

String ItemName = tv.getText().toString();
                String qty = quantity.getText().toString();
                Intent intent = new Intent("custom-message");
                //            intent.putExtra("quantity",Integer.parseInt(quantity.getText().toString()));
                intent.putExtra("quantity",qty);
                intent.putExtra("item",ItemName);
                LocalBroadcastManager.getInstance(context).sendBroadcast(intent);

MainActivity:

public void onCreate(Bundle savedInstanceState) {

  ...

  // Register to receive messages.
  // We are registering an observer (mMessageReceiver) to receive Intents
  // with actions named "custom-message".
  LocalBroadcastManager.getInstance(this).registerReceiver(mMessageReceiver,
      new IntentFilter("custom-message"));
}

...
public BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            // Get extra data included in the Intent
            String ItemName = intent.getStringExtra("item");
            String qty = intent.getStringExtra("quantity");
             Toast.makeText(MainActivity.this,ItemName +" "+qty ,Toast.LENGTH_SHORT).show();
        }
    };
