android - Using intents to pass data between activities

Question

I am trying to pass the data between Activities

I use intents to pass data between regular activities

consider the code below::

AndroidTabRestaurantDescSearchListView.java

public class AndroidTabRestaurantDescSearchListView extends TabActivity {

    // TabSpec Names
    private static final String INBOX_SPEC = "Rating";
    private static final String OUTBOX_SPEC = "Price";

    Button Photos;
    Button Filter;
    Button Search;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TabHost tabHost = getTabHost();

        // Inbox Tab
        TabSpec inboxSpec = tabHost.newTabSpec(INBOX_SPEC);
        Intent inboxIntent = new Intent(this, RatingDescriptionSearchActivity.class);
        inboxSpec.setIndicator(INBOX_SPEC);
        // Tab Content
        inboxSpec.setContent(inboxIntent);

        // Outbox Tab
        TabSpec PriceSpec = tabHost.newTabSpec(OUTBOX_SPEC);
        Intent PriceIntent = new Intent(this, PriceDescriptionSearchActivity.class);
        PriceSpec .setIndicator(OUTBOX_SPEC);
        PriceSpec.setContent(PriceIntent);


        // Adding all TabSpec to TabHost
        tabHost.addTab(inboxSpec); 
        tabHost.addTab(PriceSpec); 

        //Set the current value tab to default first tab
        tabHost.setCurrentTab(0);

    }

}

Suppose i send data from Someother activity called Activity-1 to AndroidTabRestaurantDescSearchListView as intents

Now how can i recieve the data in AndroidTabRestaurantDescSearchListView which i got from Activity-1 and then again pass it into RatingDescriptionSearchActivity

Pictoral representation is ::

{EDIT} -- If this is possible based on answers --- Ambiguity because AndroidTabRestaurantDescSearchListView is a tab activity

TabSpec inboxSpec = tabHost.newTabSpec(INBOX_SPEC);
        Intent inboxIntent = new Intent(this, RatingDescriptionActivity.class);
        intent.putExtra("keyName", value);
        inboxSpec.setIndicator(INBOX_SPEC);
        // Tab Content
        inboxSpec.setContent(inboxIntent);

Answer 1

Pass the data from Activity-1 to AndroidTabRes.. as below:

At sending activity...

Intent intent = new Intent(current.this, AndroidTabRestaurantDescSearchListView.class);
intent.putExtra("keyName","value");
startActivity(intent);

At AndroidTabRes.. activity...

  String data = getIntent().getExtras().getString("keyName");

Thus you can have data at receiving activity from sending activity...

And in your AndroidTabRestaurantDescSearchListView class, do this:

String value= getIntent().getStringExtra("keyName");

Intent intent = new Intent(this, RatingDescriptionSearchActivity.class);
intent.putExtra("keyName", value);
startActivity(intent);

Then in your RatingDescriptionSearchActivity class, do this:

 String data= getIntent().getStringExtra("keyName");
