}

}

anybody pls help me to fix this issue ...

thanx in advance .. kris

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>
