public class MainActivity extends ActionBarActivity {

private Toolbar toolbar;

private ViewPager mPager;

private SlidingTabLayout mTabs;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

toolbar = (Toolbar) findViewById(R.id.app_bar);

setSupportActionBar(toolbar);

mPager= (ViewPager) findViewById(R.id.viewPager);

mTabs=(SlidingTabLayout) findViewById(R.id.tabs);

mPager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));

mTabs.setDistributeEvenly(true);

mTabs.setBackgroundColor(getResources().getColor(R.color.colorPrimary));

mTabs.setSelectedIndicatorColors(getResources().getColor(R.color.colorAccent));

mTabs.setViewPager(mPager);

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.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();

//noinspection SimplifiableIfStatement

if (id == R.id.action_settings) {

return true;

}

return super.onOptionsItemSelected(item);
