How to have a Button on click open an app on an android?

I have made an app that will simulate the iOS.

When the settings button is clicked i need it to open the settings on the android phone.

Same thing for all of the other icons such as the phone button will open the dialer on the android phone.

How can i do this??

Here's an example of a home screen replacement app, which is what I assume you're trying to do

If not, you have to clarify what you're doing, because "simulating the iOS" could mean a lot of things.

see here on how to do things on a click.

see here on how to start an activity (the UI parts of an app). unluckily I don't know the intent to open settings, but I guess googling for "android settings intent" should give some results.
