Question: I am using google's SlidingTabLayout in my view, but i want to add dynamically new tabs to it. 
I'm using this <http://developer.android.com/samples/SlidingTabsBasic/src/com.example.android.common/view/SlidingTabLayout.html>

This is my code which initialize it:

```
    // Create the adapter that will return a fragment for each of the three
    // primary sections of the activity.
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager()); 
    //this ^ is a FragmentStatePagerAdapter

    // Set up the ViewPager with the sections adapter.
    mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    // Assiging the Sliding Tab Layout View
    tabs = (SlidingTabLayout) findViewById(R.id.tabs);

    // Setting the ViewPager For the SlidingTabsLayout
    tabs.setViewPager(mViewPager);

```

I have absolutely no idea how to add a Tab.

I thought about changing the ViewPager but in the SlidingTabLayout there is a comment:

```
/**
 * Sets the associated view pager. Note that the assumption here is that the pager content
 * (number of tabs and tab titles) does not change after this call has been made.
 */
public void setViewPager(ViewPager viewPager) {

```

Answer: 
There's probably a nicer, more efficient way, but simply calling `setViewPager()` every time you add a page to your `ViewPager` will work.
Here is a nice tutorial. <http://www.android4devs.com/2015/01/how-to-make-material-design-sliding-tabs.html> 

In short, you can supply them with your Pager Adapter. Override the getPageTitle method in order to supply something custom. E.g. 

```
@Override
public CharSequence getPageTitle(int position) {
    return _items[position].getDisplayName();
}

```
