binding.java

class View {
  Data data;
  void setData(Data data) {
    this.data = data;
    setOnClickListener(v -> run(data));
  }
}

class View {
  Data data;
  private final View.OnClickListener clickListener = new OnClickListener() {
    @Override public void onClick(View v) { run(data);}
  };
  { setOnClickListener(clickListener); }
  void setData(Data data) { this.data = data; }
}

The former allocates on every invocation of bind. When flinging you don't want it to waste time allocating in the draw path.

I mean, how many objects does Picasso.load allocate while I'm flinging?
But, every piece counts, and I should reduce waste when I know it's going to be used in this manner. 👍
