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

Answer 1

The problem here is that setOnTabChangedListener does not fire when clicking on the selected tab, and if you set an OnClickListener on the tab, you lose the normal tab behavior.

So an easy solution is to put OnClickListener on the tab, and inside it, set programatically that this is the current tab.

With TabHost:

getTabWidget().getChildAt(0).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // custom code
        tabHost.setCurrentTab(0);                                    
    }
});

With TabLayout

tabLayout.getTabAt(0)setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                    // custom code
                    TabLayout.Tab tab  = tabLayout.getTabAt(0);
                    tab.select();
                }
            }
        });
