Problem with back button on emulator when multiple activities are there in single tab

Question

I have created two tabs, say TAB1 and TAB2. For TAB1, i have loaded one Activity, say ActivityOne, into TAB1 as

Intent intent = new Intent(this,ActivityOne.class);
    TabHost.TabSpec spec = getTabHost().newTabSpec("ActivityOne")
                                       .setIndicator("Activity One",getResources().getDrawable(R.drawable.artists)).setContent(intent);
    getTabHost().addTab(spec);

This ActivityOne has extended the ActivityGroup and i added one button in this activity. By clicking on this button it will call another activity, say ActivityOne_One, as

public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(ActivityOne.this,ActivityOne_One.class);
            replaceContentView("ActivityOne_One",intent);
        }
public void replaceContentView(String id, Intent intent){
    View view = this.getLocalActivityManager().startActivity(id, intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
        this.setContentView(view);
}

When we click on that button ActivityOne_One will be launched under same TAB1. In this application i have two problems: 1) If i want to go back to ActivityOne under same TAB1 by using traditional BACK button on emulator it is not working.. 2)ActivityOne_One is launching with no animation(like sliding from right to left) effect.

If anyone know about any one of these, give your advice..

Thanks,
venu

see this link which may help you out with this. http://blog.henriklarsentoft.com/2010/07/android-tabactivity-nested-activities/

i have implemented what is advised in the link i provided. it works OK, but it is quirky and does not always redirect you BACK like you would expect. i have found that you must implement your own custom tabs to really get this desired effect.
