@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
list.add(new Fragment1());
list.add(new Fragment2());
list.add(new Fragment3());
list.add(new Fragment4());
list.add(new Fragment5());
viewPager.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {
@Override
public Fragment getItem(int i) {
return list.get(i);
}
@Override
public int getCount() {
return list.size();
}
@Nullable
@Override
public CharSequence getPageTitle(int position) {
return titles[position];
}
});
tabLayout.setupWithViewPager(viewPager);
