Unfortunately the method setIndicator(View view) only works for Android 1.6 and up (version 4). If you are supporting Android 1.5 (version 3) you can only use a String/CharSequence as an indicator using the setIndicator(CharSequence label).

See the reference: http://developer.android.com/reference/android/widget/TabHost.TabSpec.html#setIndicator

Notice that the method setIndicator(View view) is "Since: API Level 4"

Use the following code for tabs in android

Java File

public class Main extends TabActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.main1);

        TabHost tabHost = getTabHost(); // The activity TabHost
        TabHost.TabSpec spec; // Reusable TabSpec for each tab
        Intent intent; // Reusable Intent for each tab

        // Create an Intent to launch an Activity for the Movies tab.
        intent = new Intent().setClass(this, BarActivity.class);
        // Initialise a TabSpec for the Movies tab and add it to the TabHost.
        spec = tabHost.newTabSpec("Nights").setIndicator("Nights").setContent(intent);
        tabHost.addTab(spec);

        // Do the same things for the Theatres tab.
        intent = new Intent().setClass(this, BarActivity.class);
        spec = tabHost.newTabSpec("Weeks").setIndicator("Weeks").setContent(intent);
        tabHost.addTab(spec);

        intent = new Intent().setClass(this, BarActivity.class);
        spec = tabHost.newTabSpec("Months").setIndicator("Months").setContent(intent);
        tabHost.addTab(spec);
        getTabHost().getTabWidget().getChildAt(0).setLayoutParams(new 
                LinearLayout.LayoutParams(100,50)); 
        getTabHost().getTabWidget().getChildAt(1).setLayoutParams(new 
                LinearLayout.LayoutParams(100,50)); 
        getTabHost().getTabWidget().getChildAt(2).setLayoutParams(new 
                LinearLayout.LayoutParams(100,50)); 
        tabHost.setCurrentTab(0);
    }
}

and main1.xml

<?xml version="1.0" encoding="utf-8"?>

<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">
    <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">
    </FrameLayout>
</LinearLayout>
</TabHost>
