How to call a MainActivity method from ViewHolder in RecyclerView.Adapter?

Question

In a simple app project at GitHub I have only 2 custom Java-files:

1. MainActivity.java contains Bluetooth- and UI-related source code
2. DeviceListAdapter.

Answer 1

You can call Activity method by using instance of Activity like this, inside MainActivity write below code

mDeviceListAdapter = new DeviceListAdapter(MainActivity.this);

Inside Adapter

 private MainActivity _mainActivity;
 public DeviceListAdapter(MainActivity activity){
 this._mainActivity=activity;
 }

Inside your onClick method

 _mainActivity.yourActivityMethod(address);
