How to switch tabs programmatically in Android from fragment?

Question

I have implemented a TabActivity which extends FragmentActivity. It has 5 tabs each tab is a Fragment. What i am looking for is to switch between the tabs programmatically.

For eg: if i am in tab4. On button click I want to move from tab4 to tab1. Tried a lot but couldn't find the solution for this.

Tried with the following but it doesn't help.

From SecondTab

public void switchTabInActivity(String value){
    FirstTab parent;
    parent = (FirstTab) getActivity().getParent();
    parent.switchTab(value);
}

TabActivity

  /** To Change Tab*/
public void switchTab(String tabno){ 
    this.onTabChanged(tabno);
}

Answer 1

for Material support you switch the tablayout from a fragment in the following ways:

1) send a broadcast that is received by the parent activity which then modifies the tab.

context.sendBroadcast(yourintent);

2.) A modification of vino's answer,

TabLayout tabhost = (TabLayout) getActivity().findViewById(R.id.tabLayout);
tabhost.getTabAt(2).select();

tablayout is the id of the tablayout as defined in your main xml.

Answer 2

Finally i can switch between the tabs programatically from Fragments using the following line of code

  TabHost host = (TabHost) getActivity().findViewById(android.R.id.tabhost);
  host.setCurrentTab(2);

Hope it will help some one.

I have tabs (using TabLayout not TabHost(depreciated))(with Fragments) in my Main Activity in which in my first tab(fragment) with a click listener in the fragment which is for changing the current tab in my MainActivity.

I successfully change the current tab via the below in the onCreateView() method within the fragment.

TabLayout tabs = (TabLayout)((MainActivity)getActivity()).findViewById(R.id.tabs);
tabs.getTabAt(1).select();

Take a look at this answer: https://stackoverflow.com/a/5460651/198996

((TabActivity) getParent()).getTabHost().setCurrentTab(2)

Answer 5

If you're using TabLayout instead of TabHost , I suggest a modification to BENN1TH's answer that worked for me:

  TabLayout tabs = getActivity().findViewById(R.id.tab_layout);
  tabs.getTabAt(tabNumber).select(); 

(The difference is R.id.tab_layout)
