How to set the default tab of multiple swipe views with tabs?

Solution 1
The second tab is index 1, all you should need to do is add a setCurrentItem to change the current tab to the correct one after you have setup the page change listener.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_paged);
... code omitted ...
/**
* on swiping the viewpager make respective tab selected
**/
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {...}
// set the default tab to the second tab
viewPager.setCurrentItem(1, false);
}
Solution 2
You can use this code to make the desired tab selected
suppose if you want to select the second tab to be default selected tab then
actionBar.setSelectedNavigationItem(1);
will do the same

I am really stuck. I did four Swipe Views with Tabs in my main activity but what I want is when user opens the application it shows automatically the second tab not the first one.
This is my MainActivity.java
public class MainActivity extends FragmentActivity implements ActionBar.TabListener { private ViewPager viewPager; private TabsPagerAdapter mAdapter; private ActionBar actionBar; // Tab titles private String[] tabs = { "First Tab", "Second Tab", "Third Tab", "Fourth Tab" }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Initilization viewPager = (ViewPager) findViewById(R.id.pager); actionBar = getActionBar(); mAdapter = new TabsPagerAdapter(getSupportFragmentManager()); viewPager.setAdapter(mAdapter); actionBar.setHomeButtonEnabled(false); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); // Adding Tabs for (String tab_name : tabs) { actionBar.addTab(actionBar.newTab().setText(tab_name) .setTabListener(this)); } /** * on swiping the viewpager make respective tab selected * */ viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { @Override public void onPageSelected(int position) { // on changing the page // make respected tab selected actionBar.setSelectedNavigationItem(position); } @Override public void onPageScrolled(int arg0, float arg1, int arg2) { } @Override public void onPageScrollStateChanged(int arg0) { } }); } @Override public void onTabReselected(Tab tab, FragmentTransaction ft) { } @Override public void onTabSelected(Tab tab, FragmentTransaction ft) { // on tab selected // show respected fragment view viewPager.setCurrentItem(tab.getPosition()); } @Override public void onTabUnselected(Tab tab, FragmentTransaction ft) { }
And this is my main_activity.xml:
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent"> </android.support.v4.view.ViewPager>
