How can we use new View.OnClickListener directly when OnCLickListener is not static-CodePudding

I was wondering one thing today. Whenever we are setting up a ClickListener, we run this code.

tv.setOnClickListener(new View.OnClickListener() {
  @Override
  public void onClick(View v) {

  }
});

I Opened the View Class and saw the OnClickListener interface and found that it is not static. The method is like this:

public interface OnClickListener {
  /**
   * Called when a view has been clicked.
   *
   * @param v The view that was clicked.
   */
  void onClick(View v);
}

Then how are we able to access OnClickListener method directly by using class name?

CodePudding user response：

For java, "A nested interface is implicitly static." jls (9.1.1.3)

CodePudding user response：

You can implement class View.OnClickListener and then you will able to Override its method just like shown below :

public class YourActivity implements View.OnClickListener {
  @Override
  public void onClick(View v) {

  }
}
