TabHost without extending TabActivity...Example

TabDemo.java
package com.hcl.tab;
import android.app.Activity;
import android.app.ActivityGroup;
import android.content.Intent;
import android.os.Bundle;
import android.os.Bundle;
import android.util.Log;
import android.widget.TabHost;

public class TabDemo extends ActivityGroup
{  
 TabHost host;
   /** Called when the activity is first created. */

   @Override
   public void onCreate(Bundle savedInstanceState)
   {
      Log.i(this.toString(), "OnCreate");

      super.onCreate(savedInstanceState);
      setContentView(R.layout.main);

      Log.i(this.toString(), "get tab host");
       
      this.host = (TabHost) findViewById(R.id.tabhost);
      this.host.setup(getLocalActivityManager());
      host.setup();

      Log.i(this.toString(), "add tabs");
      host.addTab(host.newTabSpec("one")
                      .setIndicator("First Results")
                      .setContent(new Intent(this, FirstResultsListViewActivity.class)));

      host.addTab(host.newTabSpec("two")
                      .setIndicator("Second Results")
                      .setContent(new Intent(this, SecondResultsListViewActivity.class)));

      Log.i(this.toString(), "adjust tab size");
      host.getTabWidget().getChildAt(0).getLayoutParams().height = 35;
      host.getTabWidget().getChildAt(1).getLayoutParams().height = 35;

   }// end onCreate

}

FirstResultsListViewActivity.java

package com.hcl.tab;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class FirstResultsListViewActivity extends Activity{
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.name);
  TextView tv=(TextView)findViewById(R.id.textView1);
  tv.setText("Madhu First activity");
 }
}

SecondResultsListViewActivity .java
package com.hcl.tab;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.second);
  TextView tv=(TextView)findViewById(R.id.textView2);
  tv.setText("Madhu Second activity");
