Is there a way to pass parameters to a Runnable? [duplicate]

Simply a class that implements Runnable with constructor that accepts the parameter can do,

public class MyRunnable implements Runnable {
  private Data data;
  public MyRunnable(Data _data) {
    this.data = _data;
  }

  @override
  public void run() {
    ...
  }
}

You can just create an instance of the Runnable class with parameterized constructor.

MyRunnable obj = new MyRunnable(data);
handler.post(obj);
