Tabs in Android - through an example

As i was trying to experiment with the different widgets of Android, i developed this example to show how Tab works in Android.

And the application looks like the following:



And the next tab looks like:



The first thing we need to to do is working on the XML layout.

The XML code of the layout my example is as follows:

(?xml version="1.0" encoding="utf-8"?)
(LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
)

(TabHost android:id="@+id/TabHost01" android:layout_width="wrap_content" android:layout_height="wrap_content")
(TabWidget android:id="@android:id/tabs" android:layout_width="wrap_content" android:layout_height="wrap_content" /)
(FrameLayout android:id="@android:id/tabcontent" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="65px")
(AnalogClock android:id="@+id/AnalogClock01" android:layout_width="wrap_content" android:layout_height="wrap_content")(/AnalogClock)
(DigitalClock android:text="DigitalClock01" android:id="@+id/DigitalClock01" android:layout_width="wrap_content" android:layout_height="wrap_content")(/DigitalClock)
(/FrameLayout)
(/TabHost)
(/LinearLayout)

And the Java code for this example is as follws:

import android.app.Activity;
import android.os.Bundle;
import android.widget.TabHost;

public class tabexample extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

TabHost tabs = (TabHost)findViewById(R.id.TabHost01);

tabs.setup();

TabHost.TabSpec spec1 = tabs.newTabSpec("tag1");

spec1.setContent(R.id.AnalogClock01);
spec1.setIndicator("Analog Clock");

tabs.addTab(spec1);

TabHost.TabSpec spec2 = tabs.newTabSpec("tag2");
spec2.setContent(R.id.DigitalClock01);
spec2.setIndicator("Digital Clock");

tabs.addTab(spec2);
}
}

Hope this helps the newcomers of Android...
