I'm pretty new in android and I was wondering what really happens if I don't use "setOnClickListener" in one of my Layouts because it seems that my app can still run properly without any errors. Can anyone explain me that to me?

example:

```
myLayout = (LinearLayout) findViewById(R.id.myLayout);
myLayout.setOnClickListener(this);
myLayout2 = (LinearLayout) findViewById(R.id.myLayout2);

```
