Capturing the tab click event in Android Tabview

Question

I have a tabview in my android app with 3 tabs. The tabs are all working fine.

Now I want to perform some additional logic when the tab (on the top) of the currently active tab is clicked.

Here is an example:

In one of my tabs, I provide an option for the user to sort things in different order. When the press the tab of the currently active tab, I want to reset all these sorting.

Is it possible to capture the tab click event in tabview and perform some additional logic?

Edit: Edited for clarity.

Solution 1

If you ares till looking for a solution, I might have found one. Take a look here: Android TabWidget detect click on current tab

Solution 2

This is how your code should work :

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

        @Override
        public void onClick(View v) {
        //do whatever you need

        }
});

Solution 3

I found one clean and easy solution for Detecting clicks on selected Tab

Steps:

1: Extend TabActivity in your class. 2: In the onResume() method implement the following method

For each tab (i) implement this:

TabHost tabHost = getTabHost();

public void onResume() {

 super.onResume();
     tabHost.getTabWidget().getChildAt(0).setOnClickListener(new OnClickListener() {

                public void onClick(View v) {
                   count++;
                   tabHost.setCurrentTab(0);
    //based on your count value..you can do anything...like going back to homepage...
    //    similar thing exist on iphone (double tab a tab..it takes back to homepage)
     }
   });
 }      

Since we always have a fixed number of tabs, implementing it separately is not a problem.

TabHost.onTabChangeListener is getting fired only when the tab is changed. But I want the event to be fired, even if the tab header of the currently active tab is clicked. Is it possible to do that?

Thanks, this code works. But it is introducing a new problem. Now the tabs are not getting switched when they are clicked. Do I have to call any additional methods to make the tabs change?

I am working to solve this issue as well... so far I do not have an answer if not to implement you own "switching" code. If you succeed please share :) stackoverflow.com/questions/4337514/…

Do you mean the onResume() method of the activity? Also it would be helpful, if you can show a complete example.

Vikas shows a fix to make the tabs switch. Inside the listener add: getTabHost().setCurrentTab(getTabHost().getCurrentTab()); Or if the getCurrentTab() gives trouble, create a final int with the tab's index outside the listener, and use that instead.
