How to create our own Listener interface in android?

Question

Could someone help me to create user defined listener interface with some code snippets?

Answer 1

Create listener interface.

public interface YourCustomListener
{
    public void onCustomClick(View view);
            // pass view as argument or whatever you want.
}

And create method setOnCustomClick in another activity(or fragment) , where you want to apply your custom listener......

  public void setCustomClickListener(YourCustomListener yourCustomListener)
{
    this.yourCustomListener= yourCustomListener;
}

Call this method from your First activity, and pass the listener interface...
