Simple double-click listener that can be used like the way OnClickListener is used on a view in Android

DoubleClickListener.java

import android.os.SystemClock;
import android.view.View;
import android.view.View.OnClickListener;

/**
 * A simple double-click listener
 * Usage: 
 * 			// Scenario 1: Setting double click listener for myView
 * 			myView.setOnClickListener(new DoubleClickListener() {
 *				
 *				@Override
 *				public void onDoubleClick() {
 *					// double-click code that is executed if the user double-taps
 *					// within a span of 200ms (default).
 *				}
 *			});
 *
 * 			// Scenario 2: Setting double click listener for myView, specifying a custom double-click span time
 * 			myView.setOnClickListener(new DoubleClickListener(500) {
 *				
 *				@Override
 *				public void onDoubleClick() {
 *					// double-click code that is executed if the user double-taps
 *					// within a span of 500ms (default).
 *				}
 *			});
