Sliding Tabs in Toolbar using Material Design-open source projects angular/material

As i already wrote you can find an example here: http://www.android4devs.com/2015/01/how-to-make-material-design-sliding-tabs.html

By the way, what you need to is include in your project this code: https://developer.android.com/samples/SlidingTabsColors/src/com.example.android.common/view/SlidingTabLayout.html. So create a class in which you will paste the entire code.

Then create your activity that extends ActionBarActivity like for example this one:

public class MainActivity extends ActionBarActivity {

static final String LOG_TAG = "SlidingTabsBasicFragment";
private SlidingTabLayout mSlidingTabLayout;
private ViewPager mViewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.fragment_sample);
    Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);

    mViewPager = (ViewPager) findViewById(R.id.viewpager);
    mViewPager.setAdapter(new SamplePagerAdapter());
    mSlidingTabLayout = (SlidingTabLayout) findViewById(R.id.sliding_tabs);
    mSlidingTabLayout.setViewPager(mViewPager);

    /*
     * FragmentTransaction transaction =
     * getSupportFragmentManager().beginTransaction();
     * SlidingTabsBasicFragment fragment = new SlidingTabsBasicFragment();
     * transaction.replace(R.id.sample_content_fragment, fragment);
     * transaction.commit();
     */

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

class SamplePagerAdapter extends PagerAdapter {

    /**
     * @return the number of pages to display
     */
    @Override
    public int getCount() {
        return 5;
    }

    /**
     * @return true if the value returned from
     *         {@link #instantiateItem(ViewGroup, int)} is the same object
     *         as the {@link View} added to the {@link ViewPager}.
     */
    @Override
    public boolean isViewFromObject(View view, Object o) {
        return o == view;
    }

    // BEGIN_INCLUDE (pageradapter_getpagetitle)
    /**
     * Return the title of the item at {@code position}. This is important
     * as what this method returns is what is displayed in the
     * {@link SlidingTabLayout}.
     * 

     * Here we construct one using the position value, but for real
     * application the title should refer to the item's contents.
     */
    @Override
    public CharSequence getPageTitle(int position) {
        return "Item " + (position + 1);
    }

    // END_INCLUDE (pageradapter_getpagetitle)

    /**
     * Instantiate the {@link View} which should be displayed at
     * {@code position}. Here we inflate a layout from the apps resources
     * and then change the text view to signify the position.
     */
    @Override
    public Object instantiateItem(ViewGroup container, int position) {
        // Inflate a new layout from our resources

        View view = getLayoutInflater().inflate(R.layout.pager_item,
                container, false);
        // Add the newly created View to the ViewPager
        container.addView(view);

        // Retrieve a TextView from the inflated View, and update it's text
        TextView title = (TextView) view.findViewById(R.id.item_title);
        title.setText(String.valueOf(position + 1));

        Log.i(LOG_TAG, "instantiateItem() [position: " + position + "]");

        // Return the View
        return view;
    }

    /**
     * Destroy the item from the {@link ViewPager}. In our case this is
     * simply removing the {@link View}.
     */
    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
        Log.i(LOG_TAG, "destroyItem() [position: " + position + "]");
    }

}

of course this fragment layout:

and the pager_item.xml

This is the way to do it.
