My activity_main.xml has 2 buttons. I have implemented onClickListner(); for both of them .
For MainActivity, - > setContentView(R.layout.activity_main) This activity_main has the 2 buttons.
Button1 - setContentView(R.layout.layout1); Button2 - setContentView (R.layout.layout2);
Is this the proper way to use?? Because..
The program runs fine. The problem is that when I click Button2, the layout2 loads, I want to come back to main_activity now, So I press 'Back' button. The entire app closes..!! I am taken to homescreen of the phone.
How to get around this?? I say ViewSwitcher. I do not have a button to come back.
Any other way?? Please excuse for basic question and bad English.
You should pretty much never call setContentView() more than once. What you're describing is standard backstack behavior. Either start a new Activity whatever layout you're transitioning to, or switch to using Fragments, and add a new Fragment to the backstack instead of calling setContentView().
Both approaches will give you native behavioral support for the back button.
