Return back to previous screen in Android?

possible duplicate of How to close activity and go back to previous activity in android

The problem is, I add finish() at the end of the method I'm currently on, and the whole app closes.

I want it to return back to the previous screen by pressing the back button on the phone (I don't want to add a back button in the app)

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void secondScreen(View v) {
        setContentView(R.layout.activity_second_screen);
    }

I want to return to main from secondScreen()

It looks like you only have one Activity and you are just changing the layout with setContentView(). While you could fix this by overriding onBackPressed() and changing the layout there, this is not recommended. If you want to separate layouts then you should have two separate Activities. So you should create a second Activity as you did with the first and in the onCreate() you would have setContentView(R.layout.activity_second_screen);

Then in your, I'm guessing it is, onClick() you would use an Intent to go to that second Activity.

public void secondScreen(View v) {
    Intenet i = new Intent(v.getContext(), NextActivityName.class);
    startActivity(i);
}
