}

Simple usage

The tab item layout

R.layout.tab_simple_text

<TextView
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:textSize="18dp"
  android:gravity="center" />

The tab strip which will contain the tab items

<com.novoda.landingstrip.LandingStrip
  android:id="@+id/landing_strip"
  android:layout_height="50dp"
  android:layout_width="match_parent" />

A TabAdapter implementation to set the tab titles from PagerAdapter.getPageTitle

static class TitledAdapter extends TabAdapter<TextView> {

    private final ViewPager viewPager;

    public TitledAdapter(LayoutInflater layoutInflater, int itemLayoutId, LandingStrip landingStrip, ViewPager viewPager) {
        super(layoutInflater, itemLayoutId, landingStrip, viewPager);
        this.viewPager = viewPager;
    }

    @Override
    protected void bindView(TextView view, int position) {
        super.bindView(view, position);
        bindPageTitleToView(view, position);
    }

    private void bindPageTitleToView(TextView itemView, int position) {
        PagerAdapter adapter = viewPager.getAdapter();
        if (adapter == null) {
            return;
        }
        itemView.setText(adapter.getPageTitle(position));
    }

}

Attach the TabAdapter to the LandingStrip and the LandingStrip to the ViewPager.

LandingStrip landingStrip = (LandingStrip) findViewById(R.id.landing_strip);
TabAdapter tabAdapter = new TitledAdapter(
        getLayoutInflater(),
        R.layout.tab_simple_text,
        landingStrip,
        viewPager
);
landingStrip.setAdapter(tabAdapter);
viewPager.addOnPageChangeListener(landingStrip);
