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

    TabHost tabHost = getTabHost(); 
    tabHost.setOnTabChangedListener(this);

    TabHost.TabSpec spec;  
    Intent intent; 

    intent = new Intent().setClass(this, Main.class);        
    spec = tabHost.newTabSpec("Main Tab").
    setIndicator("Main Tab")
                  .setContent(intent);
    spec.setIndicator("", this.getResources().getDrawable(R.drawable.maintabicon) );
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, TabA.class);
    spec = tabHost.newTabSpec("Tab A").
    setIndicator("Tab A")
                  .setContent(intent);
    spec.setIndicator("", this.getResources().getDrawable(R.drawable.tabaicon) );
    tabHost.addTab(spec);


    tabHost.setCurrentTab(0);

@Override
public void onTabChanged(String tabId) {

}

You can use SharedPreference for this. So that when you choose radio button you can change your shared value to radio and when you use Check box change value to check box and use the view in your second tab according to the shared value.
