import android.widget.TabHost;
import android.widget.TabHost.TabSpec;
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TabHost tabHost=(TabHost)findViewById(R.id.tabHost);

I am new to android eclipse. I made 4 tabs(linearlayout) inside this tabview. But it is difficult to set the location on a button in one tab. How can i work with this 4 types of tabs like i am working with 4 xml files, is that possible ? How can i make the tabwidget smaller without the text not going away? , i hope this makes sense.
