Android TabWidget detect click on current tab

Question

I am trying to find way to be able to fire an onclick event on a tab when this tab is the current tab.

I did try this way (among several other) with no success thou.

public void onTabChanged(String tabId) {
    Log.d(this.getClass().getName(), ">>>>>>>>>>>>>>>>>>>>>>>> tabId: " + tabId);

    int tabs = getTabWidget().getChildCount();
    Log.d(this.getClass().getName(), "tabs: " + tabs);
    for(int i=0; i<tabs; i++){
        View tab = getTabWidget().getChildAt(i);
        if(i==tabHost.getCurrentTab()){
            Log.d(this.getClass().getName(), "tab: " + i);
            tab.setOnClickListener(this);
        }else{
            tab.setOnClickListener(null);
            tab.getOnFocusChangeListener();
        }
    }   
}

the point is that I set the onClickListener to null so, the next time I click on a tab nothing happens, but I would like to have the normal tab behavior.

Any idea there outside?

I think I have found a solution, here follows a sample code:

    intent = new Intent(this, HomeGroup.class);
    View tab1 = _inflater.inflate(R.layout.custom_tab_1,null);
    homeTab.setTag("Tab1");
    spec = tabHost.newTabSpec("Tab1").setIndicator(tab1).setContent(intent);
    tabHost.addTab(spec);

    View tab2 = _inflater.inflate(R.layout.custom_tab_2,null);
    homeTab.setTag("Tab2");
    spec = tabHost.newTabSpec("Tab2").setIndicator(tab2).setContent(intent);
    tabHost.addTab(spec);

    View tab3 = _inflater.inflate(R.layout.custom_tab_3,null);
    homeTab.setTag("Tab3");
    spec = tabHost.newTabSpec("Tab3").setIndicator(tab3).setContent(intent);
    tabHost.addTab(spec);

    tabHost.setOnTabChangedListener(this);

    //click on seleccted tab
    int numberOfTabs = tabHost.getTabWidget().getChildCount();
    for(int t=0; t<numberOfTabs; t++){
        tabHost.getTabWidget().getChildAt(t).setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                if(event.getAction()==MotionEvent.ACTION_UP){

                    String currentSelectedTag = MainTab.this.getTabHost().getCurrentTabTag();
                    String currentTag = (String)v.getTag();
                    Log.d(this.getClass().getSimpleName(), "currentSelectedTag: " + currentSelectedTag + " currentTag: " + currentTag);
                    if(currentSelectedTag.equalsIgnoreCase(currentTag)){
                        MainTab.this.getTabHost().setCurrentTabByTag(currentTag);
                        String newSelectedTabTag = MainTab.this.getTabHost().getCurrentTabTag();
                        if(newSelectedTabTag.toLowerCase().indexOf("tab1")!=-1){
                            //do smthg
                        }else if(newSelectedTabTag.toLowerCase().indexOf("tab1")!=-1){
                            //do smthg
                        }else if(newSelectedTabTag.toLowerCase().indexOf("tab3")!=-1){
                            //do smthg
                        }
                        return true;
                    }
                }
                return false;
            }
        });
    }       

Probably it is possible to improve it, but this does the work for me!
