How to handle back pressed on sub activity of TabActivity?

Question

I am implementing Tab environment as follow :

There is one class TabScreenABCActivity extends TabActivity,in that i have handled the tabchange functionality.

I have implemented MyTabGroupActivity extends TabGroupActivity. From this class, i have called MyActivity like so:

startChildActivity(getResources().getString(R.string.MyActivity), new Intent(this,MyActivity.class));

Now, MyActivity extends TabGroupActivity, from this class i called two other classes using intent like so:

Intent intent=new Intent();
intent.setClass(MyActivity.this,XYZActivity.class);
TabGroupActivity tab = (TabGroupActivity) MyActivity.this.getParent();
tab.startChildActivity("Tab", intent);

I have also overridden method to go back Activity onBackPressed() method in each activity. But it is not working properly. Can anyone guide me on how to handle it?

This is code for hard back Button of your device. here put your intent.

public boolean onKeyDown(int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {

             Intent i = new Intent(Activity1.this,Activity2.class);
                 startActivity(i);  

            return true;
        }
        return super.onKeyDown(keyCode, event);
    }
