How to call tab Onclick and OnTabChange for same tab

Question

In my project, I have two tabs and a button. For two tabs,I have two activities and button calling different activity. the thing is I am showing result of button on first tab. i.e tab0 is active on tab0Event and on button click event too. And am able to change the tab events using tabHost.setOnTabChangedListener, but now what i further want is, say suppose i click on button so now button view is displaying(tab0 is active) but again if i click on tab0, tab0 activity should be displayed.

I tried many solutions for clicking on tab, one is

getTabWidget().getChildAt(getTabHost().getCurrentTab()).setOnClickListener
      (new View.OnClickListener() {

      @Override public void onClick(View v) {
      System.out.println(getTabHost().getCurrentTab());

      } });

But when i used this code with tabChnageListner, tab change not working and i got very unexpected results. Would you please suggest solution for my problem.

Thanks.

code that is working for tab changed is as: (working fine for tab change, need to add Tab Onclick in it)

public class TabLayoutUsingTabChangeEventActivity extends TabActivity {

        @Override
        public void onCreate(Bundle savedInstanceState) {

            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);                
            final TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);
            final TabHost.TabSpec sp1 = tabHost.newTabSpec("TAB1");
            TabHost.TabSpec sp2 = tabHost.newTabSpec("TAB2");

            //Creating First Tab
            Intent intent1 = new Intent(this, Tab1Activity.class);
            sp1.setIndicator("TAB1").setContent(intent1);
            tabHost.addTab(sp1);

            //Creating Second Tab 
            Intent intent2 = new Intent(this, Tab2Activity.class);
            sp2.setIndicator("TAB2").setContent(intent2);
            tabHost.addTab(sp2);               

            //Tab Changed Event
            tabHost.setOnTabChangedListener(new OnTabChangeListener(){
                 @Override
                 public void onTabChanged(String tabId) {
                     Log.i("TabId :", tabId);
                     if(tabId.equals("TAB2")){
                     Log.i("TAB1", "TAB1 Changed");
                     Intent intent1 = new Intent().setClass(getApplicationContext(), Tab1Activity.class);
                     sp1.setIndicator("TAB1").setContent(intent1);
                     tabHost.setCurrentTab(0);
                     }
                  }
            });

            Button addNewButton = (Button)findViewById(R.id.add_new_ticket_btn);
            addNewButton.setOnClickListener(new OnClickListener(){
                  @Override
                  public void onClick(View v) {
                     Intent in = new Intent().setClass(getApplicationContext(), AddNewTicketActivity.class);
                     sp1.setContent(in);
                     tabHost.setCurrentTab(0);
                     //startActivity(in);
                 }
            });               
      }
}

You can implement this listener:

    host.setOnTabChangedListener(new OnTabChangeListener()
    {
        @Override
        public void onTabChanged(String tabId)
        {
            if (getTabHost().getCurrentTabTag().equals("tab0"))
            {
                host.getCurrentTabView().setOnTouchListener(
                        new OnTouchListener()
                        {
                            @Override
                            public boolean onTouch(View v, MotionEvent event)
                            {
                                if (event.getAction() == MotionEvent.ACTION_DOWN)
                                {
                                    if (getTabHost().getCurrentTabTag().equals("tab0")
                                    {
                                        getTabHost().setCurrentTabByTag("tab1");
                                        getTabHost().setCurrentTabByTag("tab0");
                                    }
                                    return false;
                                }
                                return false;
                            }
                        });
            }
        }
    });

Also when you add tabs set tag for every tab:

host.addTab(host.newTabSpec("tab0"));
host.addTab(host.newTabSpec("tab1"));

You can used Fragment to layout
