Four classes in one tabber in Android?

I want to do as UITabBarController does in iPhone, I have four classes and I want to work them in one tabber

as I click first tab, first class should show as I click second tab, second class should show as I click third tab, third class should show as I click fouth tab, fourth class should show

What is best and easy way to manipulate with such开发者_JAVA百科 conditions, I am new to Android developement and this is my first app if you are not clear with question, may ask again ...

The android dev site has exactly an example you're looking for. http://developer.android.com/resources/tutorials/views/hello-tabwidget.html

There are code examples. You'll need to make a tab layout xml file, edit the main.xml and then in the java code, for each tab you'll have something like this

intent = new Intent().setClass(this, AlbumsActivity.class);
spec = tabHost.newTabSpec("albums").setIndicator("Albums",
       res.getDrawable(R.drawable.ic_tab_albums))
      .setContent(intent);
tabHost.addTab(spec);

This is the Java code for implementing tab bar in android

           tabHost = getTabHost(); // The activity TabHost
    tabHost.setOnTabChangedListener(this);
    Resources res = getResources(); // Resource object to get Drawables
    tabHost = getTabHost(); // The activity TabHost
    TabHost.TabSpec spec; // Reusable TabSpec for each tab

    TabSpec firstTabSpec = tabHost.newTabSpec("tid1");
    TabSpec secondTabSpec = tabHost.newTabSpec("tid2");
    TabSpec thirdTabSpec = tabHost.newTabSpec("tid3");
    TabSpec fourthTabSpec = tabHost.newTabSpec("tid4");
    TabSpec fifthTabSpec = tabHost.newTabSpec("tid5");

    viewCache[0] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);
    viewCache[1] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);
    viewCache[2] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);
    viewCache[3] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);
    viewCache[4] = LayoutInflater.from(this).inflate(R.layout.tabs1, null);

    firstTabSpec.setIndicator(viewCache[0]);
    secondTabSpec.setIndicator(viewCache[1]);
    thirdTabSpec.setIndicator(viewCache[2]);
    fourthTabSpec.setIndicator(viewCache[3]);
    fifthTabSpec.setIndicator(viewCache[4]);

    firstTabSpec.setContent(new Intent(this, HomeTabActivityGroup.class));
    secondTabSpec
            .setContent(new Intent(this,   ProfileTabActivityGroup.class));
    thirdTabSpec.setContent(new Intent(this,
            NotificationTabActivityGroup.class));
    fourthTabSpec.setContent(new Intent(this,
            FavoritesTabActivityGroup.class));
    fifthTabSpec
            .setContent(new Intent(this, MoreTabActivityGroupNew.class));

    tabHost.addTab(firstTabSpec);
    tabHost.addTab(secondTabSpec);
    tabHost.addTab(thirdTabSpec);
    tabHost.addTab(fourthTabSpec);
    tabHost.addTab(fifthTabSpec);
