Android TabHost - actions on each tab

I am trying to create several tabs, each of which has a different action. The only drawback is that I use my own layout file, so my class extends Activity, not TabActivity. When you try to run, it fails and offers to callTabHost.Setup(ActivityGroupManager agm)

Does anyone have an idea / practical example of how this can be achieved?

Thanks in advance

This is an example of my activity, which also does not apply to TabActivity:

protected TabHost tabs;

// ...

/**
 * Init tabs.
 */
private void initTabs() {
    tabs = (TabHost) findViewById(R.id.tabhost);
    tabs.setup();
    tabs.setBackgroundResource(R.drawable.bg_midgray);

    TabHost.TabSpec spec;

    // Location info
    txtTabInfo = new TextView(this);
    txtTabInfo.setText("INFO");
    txtTabInfo.setPadding(0, 0, 0, 0);
    txtTabInfo.setTextSize(14);
    txtTabInfo.setBackgroundResource(R.drawable.bg_tab_left_inactive_right_inactive);
    txtTabInfo.setTextColor(Color.DKGRAY);
    txtTabInfo.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.TOP);
    txtTabInfo.setHeight(39);
    spec = tabs.newTabSpec("tabInfo");
    spec.setContent(R.id.tabInfo);
    spec.setIndicator(txtTabInfo);
    tabs.addTab(spec);

    // Maps
    txtTabMap = new TextView(this);
    txtTabMap.setText("MAP");
    txtTabMap.setTextSize(14);
    txtTabMap.setPadding(0, 0, 0, 0);
    txtTabMap.setBackgroundResource(R.drawable.bg_tab_middle_inactive_right_active);
    txtTabMap.setTextColor(Color.DKGRAY);
    txtTabMap.setGravity(Gravity.CENTER_HORIZONTAL|Gravity.TOP);
    txtTabMap.setHeight(39);
    spec = tabs.newTabSpec("tabMap");
    spec.setContent(R.id.tabMap);
    spec.setIndicator(txtTabMap);
    tabs.addTab(spec);

    tabs.setCurrentTab(0);

    tabs.setOnTabChangedListener(this);
}

First, define frametab in the main layout.

<tabhost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent">
  <linearlayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp">
    <tabwidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content">
      <framelayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="5dp">
      </framelayout>
    </tabwidget>
</linearlayout>
</tabhost>

Then create an action exiting TabActivity

Resources res = getResources();
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
Intent intent;
intent = new Intent().setClass(this, DashboardActivity.class);
spec = tabHost.newTabSpec("home").setIndicator("Home", res.getDrawable (R.drawable.ic_tab_dashboard)).setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, CreditCardActivity.class);
spec = tabHost.newTabSpec("sample1").setIndicator("Sample Tab",res.getDrawable (R.drawable.ic_tab_sample1)).setContent(intent);
tabHost.addTab(spec);

, :

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:drawable="@drawable/helpblue" android:state_selected="true">
  <item android:drawable="@drawable/helpgray"></item>
</item></selector>

, TabActivity .

XML :

<activity android:name=".TabActivtyClass" android:label="@string/app_name"
    android:theme="@android:style/Theme.NoTitleBar">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

- :

public class TabActivtyClass extends TabActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        TabHost tabHost = getTabHost(); // The associated TabHost

        // Create an Intent to launch given Activty for this tab
        Intent i = new Intent().setClass(this, FirstActivty.class);
        TabHost.TabSpec spec = tabHost.newTabSpec("tab_name").setIndicator("Tab Name").setContent(i); // <- references the intent we just created
        tabHost.addTab(spec);

        // And do the same for the other tabs ...
    }
}

PS Also keep in mind that the Eclipse layout editor does not work with tabs. This is an error that is already registered .
