탭을 클릭하여 변경할 수 있지만 스 와이프하면 아무 반응이 없습니다. 선택한 탭 아래에 색상 막대가 표시되지 않습니다.TabLayout의 탭을 스 와이프 할 수 없습니다.
여기 내 코드가 있습니다. 나는 대체로 this 자습서를 따라 갔지만, 이전에는 depreceated 되었기 때문에 을StoriesActivity로 변경했습니다.
StoriesActivity :
public class StoriesActivity extends AppCompatActivity implements TabLayout.OnTabSelectedListener {
//This is our tablayout
private TabLayout tabLayout;
//This is our viewPager
private ViewPager viewPager;
private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_stories);
/* +++ START Intent +++ */
Bundle extras = getIntent().getExtras();
final int authorID = extras.getInt("author_id");
final String authorName = extras.getString("author_name");
Log.i("click", Integer.toString(authorID));
/* +++ END Intent +++ */
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle(authorName);
setSupportActionBar(toolbar);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
finish();
}
});
//Initializing the tablayout
tabLayout = (TabLayout) findViewById(R.id.tab_layout);
//Adding the tabs using addTab() method
tabLayout.addTab(tabLayout.newTab().setText("Stories"));
tabLayout.addTab(tabLayout.newTab().setText("Collections"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
//Initializing viewPager
viewPager = (ViewPager) findViewById(R.id.pager);
//Creating our pager adapter
StoriesTabsAdapter adapter = new StoriesTabsAdapter(getSupportFragmentManager(), tabLayout.getTabCount());
//Adding adapter to pager
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
//Adding onTabSelectedListener to swipe views
tabLayout.addOnTabSelectedListener(this);
}
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
}

답장을 보내 주셔서 감사합니다. 주어진 페이지가 두 페이지인데, 왜 'FragmentStatePagerAdapter'를 사용해야합니까? – Sebastian
@Sebastian 업데이트 됨. https://stackoverflow.com/questions/18747975/difference-between-fragmentpageradapter-and-fragmentstatepageradapter –
여전히 이해할 수 없습니다. 제한된 수의 프래그먼트가 있으므로 'FragmentPagerAdapter'가 가장 적합합니다. 맞습니까? – Sebastian
