    Default Activities.

    Hello, I'm trying to understand what exactly is happening in my code. Thanks in advance for replying, I'm pretty confused and need some help. I have read many things on the internet but i havnt found it to be much help.

    I have followed an Android tutorial which has created an app with tabs. The code im looking at in particular is this:

    intent = new Intent().setClass(this, AlbumsActivity.class);
    and
    setContent(intent);

    I have read that "setContent(Intent) is called to specify the Intent to open the appropriate Activity". I've also read that each activity is a different screen.

    When I click on a new tab what exactly am I doing, when I click on a tab everything remains except that the tab I click on stands out (as I clicked on it), so when I click on a tab what is actually happening, am I opening a different activity? If so by opening a different activity what is actually happening? I cant see how I am though because the Activity class which is supposably opening is pretty much blank, all it has in it is a TextView object, so how come the tabs still remain on the screen.

    Im confused on what it is to switch to a different Activity, all this time I thought that when you switch Activity, you switch screens, but that cant be seeing as the View objects remain on screen when changing activity :S.

    This is the tutorial I've been following: Tab Layout | Android Developers

    Not to put you down in any way but I think you must understand java before diving into Android development. After you get good with java, you will not have much problems understanding what Android code means - after all, all is based on Java. Wish you good luck. Why don't you select that code and paste it to google, perhaps someone has posted it somewhere!

    I do have an understanding of Java. It's concept of an Activity which is confusing me. Reading different things on the internet have made me confused.

    This is what made me think that each activity is a different window:

    "An activity is the equivalent of a Frame/Window in GUI toolkits. It takes up the entire drawable area of the screen"

    To answer my own question............ What I'm actually doing is setting the content of the tab as an Activity???
