Question

I hawe many view’s in my application and now the problem is how to go back from one view to another.

What I could do it by set back Buttons in every view but i would like to use the android back hard button.

I have tried something like this:

public boolean onKeyDown(int keyCode, KeyEvent event) 
{       
  if(keyCode==KeyEvent.KEYCODE_BACK)
          {
      finish();
          }
return false;
}

But the problem is that this will close my application.
Could you please guide me for a proper solution, for example to memorize the last view was set and then to come back to this view or something like this.

Here is the code with which I am changing the view (it’s a method in my main activity):

public void CheckIfUserIsLogedIn ()
{
    int userPresence = localDatabase.CheckUserPresence();
    if (userPresence == 0) 
    {
        setContentView(R.layout.main);
    }
    else
    {
        setContentView(R.layout.userlogedon);
    }
}  

Thank you.

Look!

You are doing this wrong way..

An Activity class should only have on content View. (because it is recommended way and easy to use and implement).

And if you want to go to next View, show it under another separate Activity.

when you will finish it, you will be automatically redirected to previous Activity.

(and you don’t need to memorize the Previous View 🙂 )
