how to make the titles in pagerSlidingTabstrip dynamic?

I need to change the titles in the pager according to the items that are dynamically changing in the child fragments in the pager. I have tried it this way

     TextView title = (TextView) mPagerSlidingTabStrip.getChildAt(1);
        title.setText("Posts " + count);

But it doesnt seem to be working. Thanks in advance

you can use this to access textview of each tab

    LinearLayout mTabsLinearLayout = ((LinearLayout) mPagerSlidingTabStrip.getChildAt(0));
    for (int i = 0; i < mTabsLinearLayout.getChildCount(); i++)
    {
        TextView tv = (TextView) mTabsLinearLayout.getChildAt(i);
        tv.setText("title");
    }

Now you want perticular tab's textview so

LinearLayout mTabsLinearLayout = ((LinearLayout) mPagerSlidingTabStrip.getChildAt(0));
TextView tv = (TextView) mTabsLinearLayout.getChildAt(<perticular tab position>);
tv.setText(yourText);
